There were two stories relating to human cognition today that really had me thinking about the way we…think (how appropriate). The first involves the game of chess. You know, the game of kings invented so long ago in India:

Chess is commonly believed to have originated in North-West India during the Gupta empire, where its early form in the 6th century was known as caturanga (Sanskrit: four divisions [of the military] - infantry, cavalry, elephants, and chariotry, represented by the pieces that would evolve into the modern pawn, knight, bishop, and rook, respectively). The earliest evidence of Chess is found in the neighboring Sassanid Persia around 600 where the game is known under the name became chatrang. [Link]

Garry Kasparov, the former world chess champion (the current is India’s Viswanathan Anand) has penned a brilliant (absolute must-read) essay/review of the new book, Chess Metaphors: Artificial Intelligence and the Human Mind. The title of his essay could have easily been, “How I Learned to Stop Battling and Love the Computer.” It chronicles his victories over the machines, followed by his losses, followed finally by a type of brutally efficient partnership. Let the human worry about strategy and the machine about tactics.

…I narrowly defeated the supercomputer Deep Blue in a match. Then, in 1997, IBM redoubled its efforts—and doubled Deep Blue’s processing power—and I lost the rematch in an event that made headlines around the world. The result was met with astonishment and grief by those who took it as a symbol of mankind’s submission before the almighty computer. (“The Brain’s Last Stand” read the Newsweek headline.) Others shrugged their shoulders, surprised that humans could still compete at all against the enormous calculating power that, by 1997, sat on just about every desk in the first world.

It was the specialists—the chess players and the programmers and the artificial intelligence enthusiasts—who had a more nuanced appreciation of the result. Grandmasters had already begun to see the implications of the existence of machines that could play—if only, at this point, in a select few types of board configurations—with godlike perfection. The computer chess people were delighted with the conquest of one of the earliest and holiest grails of computer science, in many cases matching the mainstream media’s hyperbole. The 2003 book Deep Blue by Monty Newborn was blurbed as follows: “a rare, pivotal watershed beyond all other triumphs: Orville Wright’s first flight, NASA’s landing on the moon….” [Link]

I’ve been meaning to link to the recent study in Nature, “Reconstructing Indian Population History” (subscription reqd.) all week, but have been too busy (note: a document full of supplementary information is freely available here, though you need to be able to understand the way they do statistical analysis to make sense of all the charts).

As this is genetics, one would expect some comments from Razib, and indeed, one is not disappointed: here are Razib Khan’s comments on the study (see also this follow up post, where Razib creates his own plots based on the study’s data). The study gives data that relates to quite a number of different things, but the takeaway points seem to be : (1) South Indian and North Indian populations are genetically fairly mixed, and are (1a) more closely related to each other than to any other genetic/ethnic group; (2) the “Ancestral South Indian” genetic type is projected to most closely resemble a nearly extinct tribe in the Andaman Islands, the Onge (which is not to say that the Onge are themselves the “origin” of the South Indian gene pool); and (3) caste groups in the same regions of India show surprisingly high genetic difference in some cases, suggesting that caste endogamy within individual regions is a rather ancient practice.

According to Razib at least, the biggest limitation of this study is the small sample size (in the low hundreds). It seems clear that all of the conclusions being drawn from this study would be on stronger ground if they could go back and multiply the number of samples by 10.

Finally, there is a good, not overly technical synopsis of the Nature study at the Times of India: here. The TOI focuses on point (1) more than the others:

`This paper rewrites history… there is no north-south divide,” Lalji Singh, former director of the Centre for Cellular and Molecular Biology (CCMB) and a co-author of the study, said at a press conference here on Thursday.

Senior CCMB scientist Kumarasamy Thangarajan said there was no truth to the Aryan-Dravidian theory as they came hundreds or thousands of years after the ancestral north and south Indians had settled in India.

It is probably a mistake to read too much into this study, or even to accept the co-author’s bald claim that “there is no North-South divide” (Razib points out that it’s not that there aren’t genetic differences between North and South Indians — there are — but they fall on a gradient, rather than a solid barrier). Still, the study might have implications for South Indian activists who articulate a separatist “Dravidian” agenda, as well as North Indian “Aryan Invasion” proponents, who fantasize that they are really European. The only people who are really genetically “pure” on the Indian subcontinent are, it appears, the Onge.

Science fiction writer Arthur C. Clarke died earlier this week, at the age of 91. He was one of the best-known sci-fi writers of the 20th century, the author behind 2001: A Space Odyssey, among many others.

As is well-known, Clarke moved to Ceylon/Sri Lanka in 1956 — in large part for the year-around access to diving — and remained there until his death. The locale inspired at least one of Clarke’s novels, Fountains of Paradise:

Clarke lived in Sri Lanka from 1956 until his death in 2008, having emigrated there when it was still called Ceylon, first in Unawatuna on the south coast, and then in Colombo. Clarke held citizenship of both the UK and Sri Lanka. He was an avid scuba diver and a member of the Underwater Explorers Club. Living in Sri Lanka afforded him the opportunity to visit the ocean year-round. It also inspired the locale for his novel The Fountains of Paradise in which he described a space elevator. This, he believed, ultimately will be his legacy, more so than geostationary satellites, once space elevators make space shuttles obsolete. (link)

I first read The Fountains of Paradise many years ago, and I pulled it off the shelf this afternoon for a refresher. There is an intense opening, set in the classical period, 2000 years ago, involving a “Prince Kalidasa,” who does not seem to resemble the actual Kalidasa (who was not a prince, but a poet). And there are some rich descriptions of the island of Sri Lanka (named “Taprobane” — Tap-ROB-a-nee — by Clarke).

Earlier this week, an article in the Journal of Personality and Social Psychology detailed some provocative new findings:

Are you happy? Well don’t try to be happier; you might become less happy. That is the gist of a multi-cultural study published recently in the Journal of Personality and Social Psychology.

The study by University of Virginia psychology professor Shigehiro Oishi and colleagues at three other institutions found that, on average, European-Americans claim to be happy in general - more happy than Asian-Americans or Koreans or Japanese - but are more easily made less happy by negative events, and recover at a slower rate from negative events, than their counterparts in Asia or with an Asian ancestry. On the other hand, Koreans, Japanese, and to a lesser extent, Asian-Americans, are less happy in general, but recover their emotional equilibrium more readily after a setback than European-Americans.

“We found that the more positive events a person has, the more they feel the effects of a negative event,” Oishi said. “People seem to dwell on the negative thing when they have a large number of good events in their life. [Link]

So in a nutshell, what this article is saying is that “Whitey” is happier than me on a day-to-day basis (which is why he’s always whistling), but that I get over a bad day or a negative life event with greater ease than him. Could it be that since Asian families are likely to be newer to America (i.e. fewer generations removed from Asia) we are instilled with a certain sense of fatalism engrained within the family? When a grandparent or relative died in India and our parents couldn’t be there, we watched them deal with it and recover as best they could from afar. As another example, when we are the victims of racism we have to shake it off and keep going. A European American may not have to deal with some of these things. The study (and take it for what its worth) is essentially saying that Asian Americans have built up a greater immunity to bad news than European Americans.

“It is like the person who is used to flying first class and becomes very annoyed if there is a half-hour delay. But the person who flies economy class accepts the delay in stride…” [Link]

When it comes to “hot fields of scientific research”, obviously desis are at the forefront of discovery and innovation; that’s not chauvinism, that’s just logic. Millions of brown people exist and a solid chunk of them are in science, so the odds are just stacked in our favor. But I digress. And there’s exciting stuff regarding Proteome Research to get to, so let’s get back on topic! [Via MSNBC]:

A small study links the type of bacteria living in people’s digestive system to a desire for chocolate. Everyone has a vast community of microbes in their guts. But people who crave daily chocolate show signs of having different colonies of bacteria than people who are immune to chocolate’s allure.

That may be the case for other foods, too. The idea could eventually lead to treating some types of obesity by changing the composition of the trillions of bacteria occupying the intestines and stomach, said Sunil Kochhar, co-author of the study. It appears Friday in the peer-reviewed Journal of Proteome Research.

This study isn’t biased at all:

Kochhar is in charge of metabolism research at the Nestle Research Center in Lausanne, Switzerland. The food conglomerate Nestle SA paid for the study. But this isn’t part of an effort to convert a few to the dark (or even milk) side of cocoa, Kocchar said.

Here’s my favorite part of the study:

In fact, the study was delayed because it took a year for the researchers to find 11 men who don’t eat chocolate.

BWAH! In your face, people who think chocolate craving = pre-menstrual misery and weakness. MEN! They couldn’t find eleven MEN who don’t indulge.

Kochhar compared the blood and urine of those 11 men, who he jokingly called “weird” for their indifference to chocolate, to 11 similar men who ate chocolate daily. They were all healthy, not obese, and were fed the same food for five days.

The researchers examined the byproducts of metabolism in their blood and urine and found that a dozen substances were significantly different between the two groups. For example, the amino acid glycine was higher in chocolate lovers, while taurine (an active ingredient in energy drinks) was higher in people who didn’t eat chocolate. Also chocolate lovers had lower levels of the bad cholesterol, LDL.

That does it. I’m having red wine and Cadbury for dinner tonight. What to do? It’s the healthy choice.

The levels of several of the specific substances that were different in the two groups are known to be linked to different types of bacteria, Kochhar said.

They’re still not sure if it’s the bacteria that wants to be startin something, gots to be startin something or if diet affected the bacteria blah blah chicken egg.

How gut bacteria affect people is a hot field of scientific research.

I think my tummy is always warm, but that is based on highly unscientific rubbing of it, while attempting to pat my head simultaneously.

Wots this? A reference to my bellowed alma mater? GO AGS!

Not that you care, but I almost named this post A Salmagundi of NPR. However, I’m smitten with the way some Desis say “potpourri”, so I couldn’t resist the allure of that word. Oh, how do they say it? Like so: pottu-puri

None of these stories feels substantial enough to merit their own post; what does feel significant is perking up FOUR times during Morning Edition, because there are four different sepia-colored stories! That’s almost a fifth of the program! Here is what I (and undoubtedly fellow NPR-phile-Abhi, as well) heard:

1) Moray Eels are toothy!

Scientists in California have reported that Moray eels have a set of teeth within a second set of jaws, called the pharyngeal jaws, that help them capture their prey.

Once the Moray eel secures its prey with its first set of jaws, the pharyngeal jaws reach up from its throat, grabbing and pulling the prey down through its esophagus.

One of you already has an itchy-trigger-comment finger, I know it, so stop it— the brown angle is a-comin’…

Rita Mehta is a post-doctoral researcher at the University of California Davis who studies the evolution of diversity in eel feeding behavior.

Like, whoa. Not only is there a female scientist to celebrate, this has to do with my alma mater as well! w00t Davis! We study Moray Eels!

“What we discovered is that the pharyngeal jaws of Moray’s have the greatest mobility of any pharyngeal jaws ever documented,” Mehta says.

So here’s another piece of ammo for your “everything came from India” uncle -

Newton’s Infinite Series: We heard it in Malayalam first

NEW DELHI: A group of Malayali scholars had predated a ground-breaking Newton ‘discovery’ by over 250 years, according a research paper published on Monday.

The team of researchers from the Universities of Manchester and Exeter reveal that the ‘Kerala School’ identified the ‘infinite series’- one of the basic components of calculus - in about 1350.

And thus, by discovering one of the building blocks of calculus first, Mallu’s used the knowledge to, uh, well, uh, I’m not quite sure…. The researchers were quick to note that this discovery shouldn’t be used to reduce Newton’s stature but instead, add some brown names to the pantheon of genius -

[Dr George Gheverghese Joseph, one of the researcher and Honorary Reader, School of Education at The University of Manchester said,] “The brilliance of Newton’s work at the end of the seventeenth century stands undiminished - especially when it came to the algorithms of calculus.

“But other names from the Kerala School, notably Madhava, Valloppillil, and Nilakantha, should stand shoulder to shoulder with him as they discovered the other great component of calculus- infinite series.

However, Dr. Joseph does note that perhaps, just perhaps, Newton wasn’t inspired by the proverbial apple at all -

…there is strong circumstantial evidence that the Indians passed on their discoveries to mathematically knowledgeable Jesuit missionaries who visited India during the fifteenth century.

That knowledge, they argue, may have eventually been passed on to Newton himself.

Let the attribution games begin! (Hat tip - Venkat & Sindhya)

Rani woke up one morning in Singapore with an idea - why not make paneer from the left over breast milk that was sitting in her freezer? [via BoingBoing] No, I’m not kidding:

Basically this is human cheese. Why would I do that?

Well, basically, there are about twenty bags (each 150ml) of frozen breastmilk in the fridge, and they have passed their three months drinkability period, which means I would not be able to donate the milk like I did before. But the milk is still less than six month old, which is the actual expiry date.

So what do I do with it? I could make cream soup like I did several months ago. But I really wanted to try something different, and making Breast Milk Paneer sounds really exciting. [Link]

I was a bit weirded out when I started reading this. Human milk is clearly a bodily fluid, it can even transmit HIV. Emotionally, it feels very different from cows milk, even though both come from teats so that mammals can feed their young.

I mean, when you’re eating brie you don’t say “I’m having moldy bovine bodily secretions” because you don’t deconstruct cheese. Human breast milk cheese, on the other hand, lays the process bare.

I also was uneasy at the idea that she was wasting something that precious, but interestingly enough, her motive for making the paneer was to avoid wasting any of the precious fluids. Given that she had frozen breast milk that she couldn’t use and couldn’t donate, wouldn’t it be less wasteful to eat it than throw it out? My curiousity overpowered my discomfort and I kept reading.

A tragedy, in five lines;

This is Vinay and his wife Rashmi.

They were married in 2005.

He was diagnosed with a rare form of leukemia in 2006.

He is 28.

He needs a bone marrow transplant, in the next six weeks.

If you aren’t already part of the National Marrow Donor Program registry, please consider what you would be going through if this were your little brother, childhood friend or husband. Wouldn’t you want as many desis as possible to be in the database? Vinay’s greatest hope lies with someone like him, but the number of us who are registered is so low, it’s pathetic.

All it takes is a few minutes of your time. A swabbed cheek. And maybe, with that selfless gesture, you increase the chances that this person who probably has so much in common with you goes on to live the life we all deserve.

This is what Vinay’s parents have to say:

We cannot express in words what this is like. All we can do is implore you to close your eyes for a moment, and imagine that this is your son, your brother, your best friend. We are guessing you would move heaven and earth to help save his life…

Vinay is the world to us - he is warm, funny, loving. We have watched him grow from a little baby, to a young boy playing sports, to a fine young man determined to be a doctor, to a man marrying the girl of his dreams. Please help us help our son have a chance to live - to be with his wife, with us, and his friends. [Hema and Partha]

Drives are planned in Fremont, Cerritos, Anaheim and Livermore; additional information may be found here. Speaking of additional information, when I numbly surfed through Vinay’s website, the following three points made me cringe:

When a Caucasian is looking for a match they find 15 matches on an average where as opposed to an Indian they might find one match or none.

This can happen to anyone at any age and god forbid if you get into similar situation then this will be the only registry that will come to rescue.

There is no such registry in India and when an Indian kid is looking for a marrow match this registry is the only resort. [HelpVinay.org]

We’ve written about others whose lives were similarly threatened by our failure to represent in such a vital way. What would it take to move you to get involved? Would it matter if I told you that like every 8th desi, he’s from Fremont?

That he went to Ardenwood and eventually UCB (though not this UCB)?

That his favorite books were The Hobbit and Midnight’s Children?

That he liked The Godfather (but only 1 and 2), Garden State and Million Dollar Baby?

That he’s Seshu “Tiffinbox” Badrinath’s cousin?

He listens to Coltrane, Miles Davis and 2pac?

And yes, like every male I know, he likes to watch Scrubs and Sportscenter?

Do you identify with him yet? I pray you do. Because one of you could be his match and that would be the sweetest thing. My Uncle died of Leukemia and I’m sure each of us knows someone else who has been similarly affected.

I’m sure the science-fiction geeks amongst y’all know about the lost continents of Atlantis, Lemuria and Mu. These are the “missing continents” that were submerged in the Atlantic, Indian and Pacific oceans respectively.

[The story of Atlantis has its origin in the Platonic dialogues, while Lemuria was hypothesized in the late 1800s as an explanation for why there were Lemurs in both Madagascar and India but not in Africa or the Middle East. Both are now beloved of mystics and kooks. Nobody really cares about Mu, although it is sometimes confused with Lemuria.]

However, I’ll bet you’ve never heard of the Tamil analogue, the lost continent of Kumari Kandam! Proponents say Kumari Kandam is Lemuria, different names for the same continent that once covered most of the Indian ocean:

Sri Lanka together with India, Indonesia and Malaysia were a part of this continent. Many islands in the Pacific and Indian oceans are remnants of this continent that in ancient time covered the whole area of today’s ocean. [Link]

The lost continent of Kumari Kandam

It turns out that everything does not actually come from India, it comes from Kumari Kandam. And by everything, I do mean everything.

“Homo Dravida” first evolved in Kumari Kandam; it is the cradle of civilization; the birthplace of all languages in general and of the Tamil language in particular. This is where the first and second great ages (Sangams?) of the Tamils happened, not in India, but in the true Dravidian homeland, further south.

Growing up, I never understood why some people found it necessary to use a bagel guillotine. It’s easy enough to cut a bagel with a sharp knife, and it avoids squishing the bagel the way a slicer does. Part of my rejection of the tool is probably New York Jewish snobbishness (coupled with fear that if I ever embraced such a shanda, I’d be required to return my virtual circumcision and fountain pen). But it also comes from a sense that using such tools makes the whole process of bagel eating less sensual and more antiseptic.

As such, I’m agnostic about the Oxo mango slicer until I actually get a chance to try one out for myself. On the one hand, if you watch the video below, you’ll see that it makes very quick work of a mango, turning it into two halves and the seed in no time flat. And honestly, I’m better at and more interested in mango eating than mango cutting.

On the other, I wonder if the tool exists because of the big deal that non-desis make about how messy mango eating is. I remember once somebody on the radio solemnly intoned “mangos should only be eaten naked and in the ocean.” My mother scoffed and replied “White people don’t know how to eat mangos, otherwise they wouldn’t make such a mess.” Sometimes I lose the fruit under all of the “exotic” subtext going on and I don’t know how much of this machine’s appeal lies in this myth of the messy, untamable mango.

Will any of you admit to having used a tool to (ahem) split the mango? If so, did it increase or decrease your pleasure?

A soon to be published genetic study of the population of Northern India is sure to get the attention of some right wing groups who like to come up with their own alternate “theories” with regards to the history of Hindu/Muslim interaction on the sub-continent.

Scientists have confirmed what historians have known.

Genetic studies have suggested that Muslims in northern India are mostly descendants of local people who embraced Islam rather than repositories of foreign DNA deposited by waves of invaders.

The studies by scientists in India, Spain and the US indicate that while the Shias and the Sunnis in Uttar Pradesh are mostly descendants of converts, the former have some elements of paternal foreign ancestry…

“In the mtDNA, we do not see discrete signals from outside India,” Rene J. Herrera, a biologist at Florida International University in the US and one of the collaborators, said. “Thus, both are, for the most part, descendants from local caste groups,” he told The Telegraph.

However, the Shias do show some signatures of foreign DNA from southwest Asia and North Africa in the Y chromosome, Herrera said. [Link]

Within the last decade it has continued to amaze me how some strands of DNA can help corroborate or disprove decades worth of historical investigation. As the techniques become quicker and cheaper I’m sure we’ll be unlocking all kinds of secrets about the movements of humans and whether they mated with each other or killed each other.

Principal component analysis (PCA), a statistical tool that separates individuals on the basis of differences in their properties was employed to place each social group on a plot. According to this plot Shias and Sunnis are much closer to Brahmins, Bhargavas, and tribals from Karnataka than people from UAE, Yemen, Egypt, Iran, Iraq, and or Central Asian countries. PCA generated a plot that showed three clear clusters- Souther Arabian Peninsula, North East African population in upper left quadrant, East Central Asian and Middle Eastern group in the lower right hand corner, and all Indian groups can be found closer to each other to the right. [Link]

A while back I blogged about this National Geographic Project that is looking to systematically trace the movement of humanity’s genes. Have any readers swabbed their cheeks and sent in their DNA yet? Want to share your results?

All over the greater diaspora, Aunties bemoan that desi children are picky. How will they ever be satisfied? How will they ever settle down and start popping out the requisite grandkids?

Aunties can sleep better at night now that SCIENCE is on the job. Examining peoples’ behavior in online dating settings (which is equivalent to looking at biodata), they’ve noticed a few clear patterns:

Men are easy - they are generally interested in hotness above all.

Women are choosier, but it turns out their preferences are fungible. This is good news for aunties because it gives them a metric with which to translate different suitor’s attributes to a common scale, allowing them to rank apples and oranges. They can tell, for example, whether an average woman (in this study) is likely to prefer the not quite as handsome, shorter i-banker or the more gorgeous, slightly taller, high school English teacher.

What is this common scale? Money. According to these researchers, women will forgive men’s flaws if (gasp) they earn more.

Consider looks. A guy can compensate for ordinary looks with more moola, which tells us what he has to reveal in his biodata if he wants to be a playa:

Suppose you’re an ordinary-looking guy whose online picture is ranked around the median in attractiveness… And suppose you’d like to be as successful with women as a guy whose picture is ranked in the top tenth. Then you’d need to make $143,000 more than him. If your picture is ranked in the bottom tenth, you’d need to make $186,000 more than him. [Link]

Cash also acts like elevator shoes for our shorter brothers:

… a 5-foot-0 guy would need to make $325,000 more than a 6-foot-0 man to be as successful in the online dating market. [Link]

An NYU Professor of graduate and undergraduate courses in statistics, probability and analysis at NYU’s Courant Institute of Mathematical Studies has won the Abel Prize for 2007. It’s kinda like the Nobel, but for maths and he’s the first desi to win it. In other words, this is a big deal (thanks, karmakong and Sanjiv).

The Norwegian Academy of Science and Letters has decided to award the Abel Prize for 2007 to Srinivasa S.R. Varadhan, Courant Institute of Mathematical Sciences, New York. He receives the prize “for his fundamental contributions to probability theory and in particular for creating a unified theory of large deviation”. [link]

As for the caption under the good Professor’s picture: don’t you ever see an Uncle or an Auntie and just want to hug them? Especially if they seem to be radiating wisdom and kindness? Ah, I’ve been taking what Saheli is on, so pardon us as we skip through flower-laden fields, seeing the absolute best in people. He just seems like the kind of Uncle I’d love to have (as opposed to most of my Uncles, whom I have to love). Well, that and my devotion to people who are fantastic at math is probably responsible for some of this effusiveness. :D

Back on topic:

Probability theory is the mathematical tool for analyzing situations governed by chance. The theory of large deviations studies the occurrence of rare events. This subject has concrete applications to fields as diverse as physics, biology, economics, statistics, computer science, and engineering. [link]

Unfortunately, there is a typo in the above definition, “my love life” should immediately follow “computer science”.

Varadhan’s theory of large deviations provides a unifying and efficient method for clarifying a rich variety of phenomena arising in complex stochastic systems, in fields as diverse as quantum field theory, statistical physics, population dynamics, econometrics and finance, and traffic engineering. It has also greatly expanded our ability to use computers to simulate and analyze the occurrence of rare events. Over the last four decades, the theory of large deviations has become a cornerstone of modern probability, both pure and applied.[link]

For more information on this dazzling desi, peep his biography here. Next up at SM: why Anna is the only South Indian person ever to have never taken calculus. Cause for shame or America is to blame? You decide.

Absolutely zero Desi Angle (TM) here per se, but a whole heap o’ relevance for anyone who frequents the comment threads here (and if you are one of those happy souls who only reads Sepia Mutiny for the blog entries, feel free to skip this one, as I’m about to get a little parochial). But I noticed that today one of the most-emailed articles from the New York Times is an essay by Daniel Goleman on the scientific explanation for why people say, uh, intemperate things online that they would rarely say — or at least say the same way — in person. So if you’ve ever wondered what it is that causes folks on discussion boards to insult each other, call each other idiots or worse, flagrantly mis-characterize each other’s points in order to drive home some strident and ill-conceived argument of their own, and generally stink up the joint — and if you’ve perhaps caught yourself doing so, whether here on in any other online exchange — you need look no further for your answer than your orbitofrontal cortex. (I trust that one of y’all medical/scientific macacas can explain the details to the rest of us, or indeed, critique the article — politely, natch.)

The emerging field of social neuroscience, the study of what goes on in the brains and bodies of two interacting people, offers clues into the neural mechanics behind flaming.

This work points to a design flaw inherent in the interface between the brain’s social circuitry and the online world. In face-to-face interaction, the brain reads a continual cascade of emotional signs and social cues, instantaneously using them to guide our next move so that the encounter goes well. Much of this social guidance occurs in circuitry centered on the orbitofrontal cortex, a center for empathy. This cortex uses that social scan to help make sure that what we do next will keep the interaction on track. (…)

Socially artful responses emerge largely in the neural chatter between the orbitofrontal cortex and emotional centers like the amygdala that generate impulsivity. But the cortex needs social information — a change in tone of voice, say — to know how to select and channel our impulses. And in e-mail there are no channels for voice, facial expression or other cues from the person who will receive what we say.

But wait, what about :) and :P and ;) ???

True, there are those cute, if somewhat lame, emoticons that cleverly arrange punctuation marks to signify an emotion. The e-mail equivalent of a mood ring, they surely lack the neural impact of an actual smile or frown. Without the raised eyebrow that signals irony, say, or the tone of voice that signals delight, the orbitofrontal cortex has little to go on. Lacking real-time cues, we can easily misread the printed words in an e-mail message, taking them the wrong way.

And if we are typing while agitated, the absence of information on how the other person is responding makes the prefrontal circuitry for discretion more likely to fail.

TWA - Typing While Agitated. Never happens to me. No, sir. I keeps cool calm and collected. But just in case…

Bizarre and strange were the words that came to mind when I first started reading this article…

Wendy Duncan and her husband Brian are white. Nineteen months ago, the Lincolnshire housewife gave birth to a beautiful, healthy, Indian daughter. Freya, brown-skinned and dark-eyed, is not a medical miracle after a long and fruitless quest through IVF and adoption, but the product of a booming industry in India that is offering embryos for adoption.

Embryo adoption was the culmination of an 18-year journey for the Duncans during which their attempts to become parents were frustrated by nature and bureaucracy. Being white and already having a mixed-race child (from Mrs Duncan’s previous relationship) meant that they failed the criteria for a normal adoption.

IVF was unsuccessful and expensive for a family relying on Mr Duncan’s income as a lorry driver. The older Mrs Duncan got, the less the chance there was of any fertility treatment working. Their options were running out until they stumbled upon a website for the Bombay clinic. It was an easy choice.

I’ve had a warm feeling toward vultures, buzzards and other scavenger birds since the time I attended a wedding in Burkina Faso, the arid, land-locked West African country, back in the early 1990s, and looked up to see clusters of big, bad-lookin’ buzzards hanging around on trees, waiting for the event to be over so they could swoop in for the remnants of the dozen or so sheep that had been slaughtered for the occasion. It was one of those “hey, what’s up?” moments humans can have with animals, when you realize that we’re all in this together, that each creature serves its function, and that the social and cultural practices of one species have significant effects on the well-being of others. I want to say it “humanized” the buzzards for me, which obviously isn’t the right word, but it demystified them and made me appreciate them. Nuff respect to the scavenger birds.

Today tipster Sakshi brings to our attention a fascinating article from Smithsonian magazine on vultures in the subcontinent, which not only offers an interesting glimpse into the lives of these birds but, more importantly, shows how closely we and they — and other species — lead interwoven lives and how fragile that balance can be. It turns out that scientists, picking up on the observations of cattle herders and others in the field, have noticed a substantial decline in the long-billed vulture population in the subcontinent for some years. The disappearance of the lead scavenger has resulted in the accumulation of un-scavenged cattle corpses as well as the growth of packs of feral dogs, in ways that you can read about in the article. It has also placed a new burden on secondary scavenger birds that used to only come in after the larger, more powerful vultures. Those birds in turn have become vulnerable to whatever it is that has decimated the vultures:

… across the subcontinent all three species of Gyps vultures are disappearing. Dead livestock lie uneaten and rotting. These carcasses are fueling a population boom in feral dogs and defeating the government’s efforts to combat rabies. Vultures have become so rare that the Parsi in Mumbai have resorted to placing solar reflectors atop the Towers of Silence to hasten the decomposition of bodies. International conservation groups now advocate the capture of long-billed, white-backed and slender-billed vultures for conservation breeding.

So what’s the cause? After initially speculating it was some kind of virus, scientists now have strong proof that it’s a particular medication that herders give cattle that is toxic to the vultures. This brings into the story the Indian pharmaceutical industry and its history of reverse-engineering cheap drugs, which arguably has done a lot to save human lives but has also resulted in a proliferation of drugs on the market without necessarily sufficient regulation or understanding of appropriate use. The chain of effects goes on:

Public health officials say it’s likely that India’s rat population is growing too, sharing the bounty of abandoned carcasses with feral dogs, and raising the probability of outbreaks of bubonic plague and other rodent-transmitted human diseases. Livestock diseases may increase too. Vultures are resistant to anthrax, brucellosis and other livestock diseases, and helped control them by consuming contaminated flesh, thus removing reservoirs of infectious organisms. Some municipalities are now resorting to burying or burning carcasses, expending precious land, firewood and fossil fuels to replace what Rahmani calls “the beautiful system nature gave us.”

In all, this is a powerful story of interdependence and one that, just possibly, might have a happy ending, as the governments of India, Pakistan and Nepal have grown aware of the problem and taken remedial action. Read the article for that story as well as a rich perspective on the interconnectedness of all things, one that might, at a minimum, help us step back from some of the ridiculous disputes over trivial matters that we humans, including those of us who hang out at this site, sometimes so enjoy wallowing in. There’s also a nice sidebar interview with the article’s writer, Susan McGrath:

Well, I knew that my trip to India was going to be different than most people’s trips to India. All my friends were saying, “Oh you’re so lucky! The crafts! The clothing! The wildlife!” And I spent half my time in India in carcass dumps.

Glad you did, Ms. McGrath. And to the vultures: keep ya ugly heads up, my avian brothers and sisters, stay strong!

Someone want to let me in on the secret that is South Carolina? It was the only state of the union that, until recently, has a capital forgotten on almost every geography bee and prompted one to think of secession and stars-and-bars. Suddenly, everyone from my boss to a close friend is interested in purchasing property there, and this patch of Southern Appalachia is turning into quite the desi magnet. Not only has a doctor friend set up shop in Columbia, but has invited my very eager brother to do so as well.

I considered it all a coincidence until the discovery that famous geophysicist, Pradeep Talwani, is a professor at the University of South Carolina and director of the South Carolina Seismic Network, and Vijay Vulava has joined the faculty of the College of Charleston as an environmental geochemist. Hmmmm … the thot plickens.

Hark, what light through yonder passport photo breaks? Move over, Michael Manga - there’s a new sexy desi geologist in town. Unfortunately, like Michael, Vijay is married. His wife, Sirisha Vadlamudi, is an electrical engineer who specializes in virtual and augmented reality (sound familiar?).

Not to be excluded from the running is UTIG’s Abhijit Gangopadhyay.

While you investigate the South Carolina riddle, I’ll keep my eyes peeled for more kannu-candy at the upcoming SEG conference in New Orleans.

I’ve decided to split the speculation concerning the science that may have been involved in the plot into a separate post since it is getting long.

Some experts think that the bomb might have involved TATP, the same compound used by the 7/7 bombers.

While there are several liquid explosives that could be used to bring down an aircraft, chemists believe it is more likely that terrorists planned to mix liquid materials that are not themselves explosive but can be combined into a bomb. The liquid explosives that are sufficiently destructive in their own right to blow up a plane are generally too unstable or too easily detected to be readily smuggled aboard.

A more subtle approach would be to combine two or more liquids that are stable by themselves, but which form a powerful explosive when mixed together. A prime candidate for this would be triacetone triperoxide (TATP), the explosive used by the July 7 bombers. Its two raw ingredients are both liquids, which could potentially be carried on board in sufficient quantities in containers such as bottles of shampoo or contact lens solution.

These could then be mixed in a toilet to make TATP, which is a crystalline white powder. The problem here is that the solid has to be dried before it becomes a reliable explosive. It can also be difficult to detonate, as attested by the failure of the attempted suicide attacks on London on July 21 last year.

The problems of assembling and then detonating an improvised bomb of this sort in an airline toilet could explain why the terrorists targeted so many aircraft. It is likely that many of the devices would have failed, so attacking 10 flights would have greatly increased the chances of blowing up one or two. [Link]

There have also been at least two prior terrorist attacks planes using liquid explosives, KAL 858 and PAL 434. [Details follow after the fold]

On March 16th of this year, Abhi wrote about a first-in-man trial in the UK which went horribly awry for six volunteers who experienced heart, kidney and liver failure after they were given an experimental drug made by German firm TeGenero, called TGN 1412:

It is an anti-inflammatory agent makers hoped would become a lucrative treatment for rheumatism, leukaemia and multiple sclerosis.[link]

When we first posted about this nightmarish story, Doctors said they were “in the dark” and that they did not know exactly how these human guinea pigs would be affected. Unfortunately, now it seems we have an answer—and it is tragic:

Victims of the disastrous “Elephant Man” drugs trial have been told they face contracting cancer and other fatal diseases as a result of being poisoned in the bungled tests. [link]

Nav Modi, 24, whose bloated face and swollen chest led to the nickname “Elephant Man”, said he did not know how long he would live.[link]

“It’s a really bizarre feeling when you discover you might be dead in a couple of years or even in a couple of months,” he said. “I feel like I’ve given away my life for £2,000.”[link]

It seems that not only were the volunteers (quite predictably) assured before participating in the trial that they would not suffer any life-threatening illnesses, they were told that after it was obvious that the test results were disastrous, too.

Four months later he still suffers from occasional lapses of memory, severe headaches, back pain and diarrhoea. (Modi) and the others had been led to believe that while their symptoms might persist for a while, their long-term future was not at risk.[link

Wrong. So very wrong.

One of the six victims was told last week he is already showing “definite early signs” of lymphatic cancer.

He and three others have also been warned that they are “highly likely” to develop incurable auto-immune diseases.[link]

Usually, an article related to the process of sex selection would sadden me because I think the brown preference for boys blows, but this one which was submitted to our news tab (Thanks, Premii!) had me laughing, because I immediately thought of celebrity evidence to back it up. Apparently, it is possible to choose whether you are going to have a male or female…calf:

Want to have a baby boy? Tuck into the burgers, fries and ice cream. Want a girl? Then go on a diet and lose some weight.

It works for cows, according to John Roche, a scientist at New Zealand’s dairy research organisation Dexcel. “And we would expect what holds true for one mammal will hold true across the board,” he said.

Also, if it can be applied to celebrities, it must be true. Angelina stayed rather sleek while incubating the most attractive celebrity baby possible, to the point where useless weeklies which cost $1.99 and all run the same story (though with slightly different covers) speculated that based on the lack of fat around her elbows, the lippy star was way too skinny. (I kid you not. I read this while waiting for my train.) Angelina, the magazines screeched, was “dangerously thin”. She had a girl, in case you haven’t had access to television, radio, newspapers, the internet, carrier pigeons, flaming arrows etc.

Meanwhile, Kate Hudson put on an amount which was almost equivalent to my mother’s entire body weight pre-pregnancy-with me; Hudson gave birth to a boy, Ryder. Britney…well, we all know about Britney. Do not read anything in to the fact that the quote I’m about to use contains the word “heifers”. I am establishing no connection between Britney and one of those. If you are currently thinking that thought, it’s your bad, not mine. ;)

They found that cows that gained weight before conceiving were more likely to give birth to bull calves. Those shedding kilos before conception had a better chance of producing heifers (females).

Roche told the Waikato Times , published in Hamilton at the heart of New Zealand dairying country, the research underlined the theory that humans had some control over the sex of their children…Roche said it was not clear exactly why weight affected the sex of a cow’s offspring.

Today’s featured picture of mictyris longicarpus captured my attention for two reasons:

1) I am absolutely terrified of crustaceans and think eating them is just gross. They remind me of insects and one of you more useful (read: non-poli-sci major) types told me that the two groups of ickiness are actually related.

2) LOOK at those COLORS. Have you ever seen a prettier icky creature?

Here, learn something:

The light blue soldier crab (Mictyris longicarpus), inhabits beaches in the Indo-Pacific region. Soldier crabs filter sand or mud for microorganisms. They congregate during the low tide, and bury themselves in a corkscrew pattern during high tide, or whenever they are threatened.

I googled a bit more and found out that this thing (more formally known as the “soldier crab”) scurries about the Andaman and Nicobar Islands. This proves my E.C.F.I.-Uncle-esque theory that everything South Asian is prettier. ;)

I just wanted to make sure that everyone was aware that AIDS “turns” 25 this week. India now has the largest number of infected people and is still trending downhill:

Twenty-five years after the first AIDS cases were reported, there is no sign of a halt to the pandemic which is likely to spread to every corner of the globe, the head of the United Nations’ AIDS agency said.

Peter Piot was speaking as UNAIDS released a report which declared that the world’s response to the disease, that has infected about 65 million people and killed 25 million, has been nowhere near adequate. Five years after a special U.N. session pledged its commitment to halt the AIDS pandemic, only a few countries have met the targets laid down…

India has the largest number of people living with the virus. With 5.7 million infections, it has overtaken South Africa’s total of 5.5 million. But, the epidemic is still at its worst in sub-Saharan Africa, where 90% of the world’s HIV-infected children live. [Link]

The first reported case in India came nearly 5 years after the first reported case in the U.S.

The first case of HIV infection in India was diagnosed among commercial sex workers in Chennai, Tamil Nadu, in 1986. Soon after, a number of screening centres were established throughout the country. Initially the focus was on screening foreigners, especially foreign students. Gradually, the focus moved on to screening blood banks. By early 1987, efforts were made up to set up a national network of HIV screening centres in major urban areas. [Link]

The statistics are grim:

The UN Population Division projects that India’s adult HIV prevalence will peak at 1.9% in 2019. The UN estimates there were 2.7 million AIDS deaths in India between 1980 and 2000. During 2000-15, the UN has projected 12.3 million AIDS deaths and 49.5 million deaths during 2015-50.

A 2002 report by the CIA’s National Intelligence Council predicted 20 million to 25 million AIDS cases in India by 2010, more than any other country in the world. [Link]

So you guys tell me. We know what some of the problems are. What more can be done to stop this boulder from rolling?

In what can only be described as poetic injustice, the most priapic fruit in the world may go extinct within five to ten years for lack of sex. I feel for you, brutha. India’s glorious, 12” long banana fruit has been neutered by the cruel, cruel world (thanks, tipster):

The world’s most popular fruit… is in deep trouble. Its genetic base, the wild bananas and traditional varieties cultivated in India, has collapsed…

The main hope for survival of the Cavendish [variety] lies in developing new hybrids resistant to the [black sigatoka] fungus, but… the seedless modern fruit does not reproduce sexually and has to be bred from cuttings.

… wild banana species are rapidly going extinct as Indian forests are destroyed… In fact many of the genes that could save the Cavendish may already have been lost… One variety that contains genes that resist black sigatoka survives as a single plant in the botanical gardens of Calcutta… [Link]

The banana’s problem is that it is the seedless, infertile mutant cousin of a wild herb. The absence of seeds makes its fruit edible, but also genetically vulnerable… They have survived only because for some 10,000 years banana-lovers have propagated the fruit by taking shoots from the base of the plants…

The most widespread banana disease currently is a leaf fungus called black Sigatoka. It cuts yields by 50 percent or more on hundreds of millions of small farms across the tropics. Commercial banana plantations keep up production with weekly applications of fungicides - the most intensive application of chemicals on any major food crop. But now a new strain of an old disease, Panama disease, threatens to make even fungicides useless…

“In the 1970s we controlled Black Sigatoka by spraying 10 to 12 times a year…” That frequency has jumped to almost weekly… [Link]

NASA has inked a deal to launch two scientific instruments on an Indian rocket bound for the moon within the next two years. Even space is being outsourced:

The picture either means ‘satellite’ or ‘no head-in parking’

U.S. space agency NASA entered into an agreement with the Indian Space Research Organisation (ISRO) on Tuesday to send two scientific instruments on board Chandrayaan-I, the country’s first unmanned moon mission scheduled for 2008…

[The U.S. instruments include] a mini synthetic aperture radar (miniSAR), developed by the agency’s applied physics laboratory and a moon mineralogy mapper, built by [NASA] Jet Propulsion Laboratory…

Chandrayaan-I will be launched from… Sriharikota on the east coast of Andhra Pradesh, using the new polar satellite launch vehicle… [Link]

The first payload will look for polar ice on the moon and the other will study the moon’s surface mineral composition. [Link]

NASA won’t be the only hitchhiker in the galaxy — the Europeans are also aboard:

… the Chandrayaan payload… will have 15-20 instruments, including 11 from India and three from the European Space Agency. [Link]

India’s own payload is a lunar surveyor:

The instruments will perform photo-geological mapping of the lunar surface apart from mineral content. [Link]

A new theory in cosmology sounds much like the Hindu, Jain and Buddhist concepts of cyclical creation and mind-boggling timescales. I don’t mean to sound like Religious Uncle, rather to evoke a neat coincidence (via Slashdot):

The universe is at least 986 billion years older than physicists thoughtThe universe may be 986 billion years older than previously thought, and creation may be cyclical and is probably much older still, according to a radical new theory. The revolutionary study suggests that time did not begin with the big bang 14 billion years ago…

The standard big bang theory says the universe began with a massive explosion, but the new theory suggests it is a cyclic event that consists of repeating big bangs and big crunches - where every particle of matter collapses together…

“I think it is much more likely to be far older than a trillion years though,” said Prof Turok. “There doesn’t have to be a beginning of time. According to our theory, the universe may be infinitely old and infinitely large…” [Link]

… According to Steinhardt and Turok, today’s universe is part of an endless cycle of big bangs and big crunches, with each cycle lasting about a trillion years. At every big bang, the amount of matter and radiation in the universe is reset, but the cosmological constant is not. Instead, the cosmological constant gradually diminishes over many cycles to the small value observed today… the cosmological constant decreases in steps, through a series of quantum transitions. [Link]

As I’ve noted before, the Hindu concept of time is so over-the-top that it beats even the Chinese long view quoted sanctimoniously by bestsellers on the business shelves:

… the life cycle of Brahma is… 311 trillion years. We are currently in the 51st year of the present Brahma and so about 155 trillion years have elapsed… [Link]

Via our newsline we see that Thursday’s issue of the journal Nature has a paper out which indicates that dentistry may be one of the world’s oldest professions. The paper, which has an Italian as the lead author, is titled Early Neolithic Tradition of Dentistry (paid subscription required). Now when we are old uncles/aunties we can brag to our children that South Asians invented denistry also.

Proving prehistoric man’s ingenuity and ability to withstand and inflict excruciating pain, researchers have found that dental drilling dates back 9,000 years.

Primitive dentists drilled nearly perfect holes into live but undoubtedly unhappy patients between 5500 B.C. and 7000 B.C., an article in Thursday’s journal Nature reports. Researchers carbon-dated at least nine skulls with 11 drill holes found in a Pakistan graveyard.

That means dentistry is at least 4,000 years older than first thought — and far older than the useful invention of anesthesia.

This was no mere tooth tinkering. The drilled teeth found in the graveyard were hard-to-reach molars. And in at least one instance, the ancient dentist managed to drill a hole in the inside back end of a tooth, boring out toward the front of the mouth. [Link]

My whole life I had looked down on people with multiple cavities because I had never had one. I usually snubbed these “enamelly challenged” because I saw them as being weak and unable to resist candy. I got my just desserts though. Last year I got my first (and I swear it will be my last) cavity. By the time the doctor was done she had pulled two of my innocent teeth just to get to the offending tooth which she then reconstructed with a crown. My wisdom teeth surgery was even worse (warning: NSDL). Apparently they were like upside down. I can’t even begin to imagine how people were able to withstand the pain in the Neolithic.

The site of Mehrgarh in Baluchistan lies along the principal route connecting Afghanistan to the Indus valley. After intermittent occupations by hunter-gatherers, Mehrgarh’s subsistence economy shifted to the cultivation of barley and wheat, cotton domestication and cattle breeding. Diachronic archaeological evidence records an increasingly rich cultural life, with technological sophistication based on diverse raw materials. Excavation of the Neolithic cemetery known as MR3 yielded more than 300 graves created over a 1,500-year time span…

Whatever the purpose, tooth drilling on individuals buried at MR3 continued for about 1,500 years, indicating that dental manipulation was a persistent custom. After 6,500 yr BP, the practice must have ceased, as there is no evidence of tooth drilling from the subsequent MR2 Chalcolithic cemetery, despite the continuation of poor dental health. [Link]

Teeth are the greatest find in any paleontological/archeological expedition. Measuring istope ratios can even tell you what the people ate. I keep two of my old teeth on my desk at home. This is just in case my body is lost during some adventure and someone wants to learn about my lifestyle when I was still alive.

Red rain is coming down…
Red rain is pouring down
Pouring down all over me…

— Peter Gabriel, ‘Red Rain’

In 2001, Kerala residents heard a sonic boom in the sky followed by two months of mysterious red rain. A physicist in Kerala took samples of the downpour and found what looked like cells without DNA. He believes that the material came from a meteor which exploded while aloft and speculates that the specimens were aliens hitching a panspermic ride. He’s pretty sure they aren’t red earth in pouring rain (thanks, masale.wallah):

On 25 July, 2001, blood-red rain fell over the Kerala district of western India. And these rain bursts continued for the next two months. All along the coast it rained crimson, turning local people’s clothes pink, burning leaves on trees and falling as scarlet sheets at some points.

Investigations suggested the rain was red because winds had swept up dust from Arabia and dumped it on Kerala. But Godfrey Louis, a physicist at Mahatma Gandhi University in Kottayam, after gathering samples left over from the rains, concluded this was nonsense. ‘If you look at these particles under a microscope, you can see they are not dust, they have a clear biological appearance.’ Instead Louis decided that the rain was made up of bacteria-like material that had been swept to Earth from a passing comet. In short, it rained aliens over India during the summer of 2001…

Dr. Godfrey Louis has just released these magnified images of the cells in a new paper in Astrophysics and Space Science (via Digg).

A new story in Nature reiterates that an Indian-American nuclear scientist’s claims of tabletop fusion are suspect (thanks, Saheli):

Dr. Rusi Taleyarkhan

Several Purdue researchers said Rusi Taleyarkhan, a Purdue professor of nuclear engineering, has stymied their attempts to verify or refute aspects of his controversial “bubble fusion” experiments since late 2003, when he joined Purdue’s faculty. In an article published online Wednesday in the journal Nature, they said their confidence in his work at Purdue and previously at Oak Ridge National Laboratory in Tennessee has been seriously shaken…

Seth Putterman, a professor of physics at the University of California, Los Angeles, who received a $350,000 grant from the Defense Department to try to reproduce Taleyarkhan’s findings, said he has been unable to do so. [Link]

In February 2005, the BBC commissioned a collaboration between Seth Putterman and Ken Suslick (two leading sonoluminescence researchers) to reproduce Taleyarkhan’s work. Using similar acoustic parameters, deuterated acetone, similar bubble nucleation, and a much more sophisticated neutron detection device, the researchers could find no evidence of a fusion reaction. This work was reviewed by a team of four scientists, including an expert in sonoluminescence and an expert in neutron detection, who also concluded that no evidence of fusion could be observed. [Link]

Taleyarkhan’s paper had skeptics from the beginning — this excerpt is from 2002:

However, many scientists remain sceptical of the results reported by Rusi Taleyarkhan and his colleagues at Oak Ridge National Laboratory in Tennessee, including other researchers at ORNL who tried and failed to repeat the experiments.

The second ORNL team say they used a more sophisticated detection system. But team member Mike Saltmarsh says: “Our experiment saw no evidence for nuclear fusion. This does not prove that no nuclear fusion is going on - it’s virtually impossible to prove a negative - but it does show that if it exists, it is at a very low level…” [Link]

You have all most likely heard of the Kennewick Man:

In 1996, there was a boat race on the Columbia River, near Kennewick, in Washington State, in the extreme northwestern United States. Two fans pulled ashore to get a good viewpoint of the race, and, in the shallow water at the edge of the bank, they found a human skull. They took the skull to the county coroner, who passed it to archaeologist James Chatters. Chatters and others went to the Columbia and retrieved a nearly complete human skeleton, with a long, narrow face suggestive of a person of European descent. But the skeleton was confusing to Chatters; he noticed that the teeth had no cavities and for a 40-50 year old man (the most recent studies suggest he was in his thirties), the teeth were extremely ground down. Cavities are the result of a corn-based (or sugar-enhanced) diet; grinding damage usually results from grit in the diet. Most modern people don’t have grit in their food, but do consume sugar in some form and so do have cavities. And Chatters spotted a projectile point embedded in his right pelvis, a Cascade point, normally dated between 5,000 and 9,000 years before the present. It was clear that the point had been there while the individual was alive; the lesion in the bone had partially healed. Chatters sent off a bit of the bone to be radiocarbon dated. Imagine his astonishment when he received the radiocarbon date as over 9,000 years ago. [Link]

The cover of Time Magazine this week is dedicated to new discoveries about the Kennewick Man reported inside. For many years his remains were the subject of a heated court battle. Native Americans claimed that they had the right to reclaim and bury his remains (thereby preventing scientific study) because he was one of their own. The Time Magazine article (subscription currently required) explains how forensics reveals that the Kennewick Man was not racially what we would consider Native American, but rather Polynesian or Ainu. He therefore predates existing Native American tribes. Indolink.com takes it a step further and includes speculation that he may have been from South Asia. It gets tricky because some people use “South Asia” when they really mean “Southeast Asia”:

Now it appears that analysis of Kennewick Man, places him “closer to southern Asians and nearly equidistant to modern Native Americans and Polynesians.”

That’s because the skull “appears to have strongest morphological affinities with populations in southern Asia, and not with American Indians or Europeans in the reference samples” according to one study.

The interpretations by anthropologists Joseph F. Powell and Jerome C. Rose are based on a scientific technique called craniofacial morphometric analysis. It involves detailed study of the shape of the skull and face, using a sophisticated method called multivariate analysis. In some cases, more than 60 different dimensions of a skull are measured and compared with comparable dimensions considered typical of specific racial groups. [Link]

Last January I posted a link to an online test that you can take, which supposedly reveals if you have even a subconscious racial bias. One of the researchers conducting the study was Harvard’s Mahzarin Banaji. Banaji and her colleagues have just revealed results from their latest set of experiments which, if true, corroborates what many of us have suspected about politics. I love a bit of controversy on a Monday. From the Washington Post:

The field of social psychology has long been focused on how social environments affect the way people behave. But social psychologists are people, too, and as the United States has become increasingly politically polarized, they have grown increasingly interested in examining what drives these sharp divides: red states vs. blue states; pro-Iraq war vs. anti-Iraq war; pro-same-sex marriage vs. anti-same-sex marriage. And they have begun to study political behavior using such specialized tools as sophisticated psychological tests and brain scans…

Emory University psychologist Drew Westen put self-identified Democratic and Republican partisans in brain scanners and asked them to evaluate negative information about various candidates. Both groups were quick to spot inconsistency and hypocrisy — but only in candidates they opposed.

When presented with negative information about the candidates they liked, partisans of all stripes found ways to discount it, Westen said. When the unpalatable information was rejected, furthermore, the brain scans showed that volunteers gave themselves feel-good pats — the scans showed that “reward centers” in volunteers’ brains were activated. The psychologist observed that the way these subjects dealt with unwelcome information had curious parallels with drug addiction as addicts also reward themselves for wrong-headed behavior.

Another study presented at the conference, which was in Palm Springs, Calif., explored relationships between racial bias and political affiliation by analyzing self-reported beliefs, voting patterns and the results of psychological tests that measure implicit attitudes — subtle stereotypes people hold about various groups.

That study found that supporters of President Bush and other conservatives had stronger self-admitted and implicit biases against blacks than liberals did.

Not so fast, say a few expected critics.

Brian Jones, a spokesman for the Republican National Committee, said he disagreed with the study’s conclusions but that it was difficult to offer a detailed critique, as the research had not yet been published and he could not review the methodology. He also questioned whether the researchers themselves had implicit biases — against Republicans — noting that Nosek and Harvard psychologist Mahzarin Banaji had given campaign contributions to Democrats.

Lunar / “Asian” New Years is always an occasion for me to reflect on how different South (brown) Asians are from East and Southeast (yellow) Asians. However, there is an area in which we, apparently, are a mix of both African/European and East Asian genotypes. The area in question is earwax:

Earwax comes in two types, wet and dry. The wet form predominates in Africa and Europe, where 97 percent or more of people have it, and the dry form among East Asians. The populations of South and Central Asia are roughly half and half. [Link]

This is evidence, apparently, of some yellow in the woodpile:

The dry form, the researchers say, presumably arose later in northern Asia, because they detected it almost universally in their tests of northern Han Chinese and Koreans. The dry form becomes less common in southern Asia, probably because the northerners with the dry earwax gene intermarried with southern Asians carrying the default wet earwax gene. [Link]

There must have been a lot of intermarriage if half the populations of South Asia have the East Asian gene. It turns out that the earwax gene is also related to that other, oh so polite topic of conversation, body odor:

Since it seems unlikely that having wet or dry earwax could have made much difference to an individual’s fitness, the earwax gene may have some other, more important function. Dr. Yoshiura and his colleagues suggest that the gene would have been favored because of its role in sweating. They write that earwax type and armpit odor are correlated, since populations with dry earwax, such as those of East Asia, tend to sweat less and have little or no body odor, while the wet earwax populations of Africa and Europe sweat more and so may have more body odor. [Link]

This would imply that half of all South Asians sweat little and have little B.O. Having recently ridden the Delhi metro, my question is … where are they ?

A new paper published in the Proceedings of the National Academy of Sciences (subscription required) offers a counter theory to the long held Aryan Invasion Theory (thanks for the tip “Gujjubhai” and “Mauritious”). But before I get into that, I want to address a pet peeve of mine. The word “theory” is one of the most mis-used words in the English language. When most people use the word theory, they actually mean to use “hypothesis” or “hunch.” A theory by definition means:

A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

By definition a theory has already stood up to repeated challenges, and on the basis of scientific evidence has held true despite many assaults on its validity. Therefore the Theory of Evolution isn’t just some willy-nilly hunch. It has taken on and turned aside all would-be challengers. Everybody “knows” that gravity is real, but did you know that Newton’s gravity is in fact a theory? When dealing with physics that approach the speed of light, the Newtonian Theory of Gravity fails, and Einstein’s Theory of Relativity takes over. Now that we are past that let’s go back to the PNAS paper. First, what is the “Aryan Invasion Theory”:

… a term that refers to the theory developed by 19th Century European linguists to explain the similarity between Sanskrit and European languages, by hypothesising that peoples originating outside India invaded or migrated to India. Another view is that this theory was developed as a means to show the superiority of European Aryan race. Max Muller and other western scholars who studied Sanskrit were very impressed with it and wanted to develop a link of this brilliant language with there own race i.e Europeans. They found some roots common in german and sanskrit and invented AIT. There is no archaeological evidence for the invasion. In ancient times there were abundant contact between civilization in India and Europe and European languages borrowed lot of words/roots from Sanskrit. Interesting fact is that modern non-Indians still cling to this theory even though it has no locus standi or a scientific basis. [Link]

A great many tipsters are informing us that People Magazine has included an Indian American as one of its Sexiest Men Alive. Yeah, he’s half Indian and he is “sexy.” So what, I say? That doesn’t really seem that blog-worthy to me. However, what eventually convinced me as to the importance of getting this story out to the people isn’t the fact that he is representing Indian Americans, but rather that he is a proxy for the previously unacknowledged sexiness of all geologists in the Earth and Space Sciences Departments of schools in the University of California system. Meet Michael Manga:

People magazine has featured a geophysicist of Indian origin alongside the likes of U2 frontman Bono in the ‘Smart Guys’ section of its ‘Sexiest Man Alive’ issue.

Michael Manga, a 37-year-old geology professor of UC Berkeley, who won the $500,000 MacArthur ‘genius’ grant earlier in 2005, shares pages with stars like Matthew McConaughey, Matt Damon, Jake Gyllenhaal and Orlando Bloom among others.

“My first inclination, of course, was to say no, because that’s not how I perceive myself,” Manga, father of two boys, said. “But it is a way to let people know about science and that it is OK to be a scientist.” [link]

I think it is a particularly sad commentary on the decadence of our culture that it has taken THIS long to point out that there are in fact “sexy” Indian geologists that deserve to share the same page as Bono.

Manga was one of only two men in academia admitted to the ranks of America’s dreamiest dudes. “That’s why I agreed to do this,” he explains.

“I wanted to get information out to people who wouldn’t normally hear or see anything about science.”

I really wanted to write a post about the U.S. Federal Court slapping down “Intelligent Design” in Dover, Pennsylvania today:

A federal judge in Pennsylvania ruled today that it is unconstitutional to compel teachers there to present “intelligent design” as an alternative explanation to evolution because it amounts to establishing religion in public schools.

I couldn’t find a strong Desi-angle beyond what we’ve already blogged about though. So instead, I’ve decided to write a post about “Un-intelligent Design.” Most people know that Hitler’s Third Reich was fascinated by the occult and was always looking for mystical weapons and methods in order to defeat the Allies. Essentially, that is what the plot of Raiders of the Lost Ark is about. He is also thought to have been fascinated by Eastern religions. After reading the following article out today in the Scotsman, I wondered if the brutal dictator Joseph Stalin might have been reading up on his Hindu mythology when he came up with this VERY unintelligent design idea:

The Soviet dictator Josef Stalin ordered the creation of Planet of the Apes-style warriors by crossing humans with apes, according to recently uncovered secret documents.

Moscow archives show that in the mid-1920s Russia’s top animal breeding scientist, Ilya Ivanov, was ordered to turn his skills from horse and animal work to the quest for a super-warrior…

According to Moscow newspapers, Stalin told the scientist: “I want a new invincible human being, insensitive to pain, resistant and indifferent about the quality of food they eat…”

Mr Ivanov’s experiments, unsurprisingly from what we now know, were a total failure. He returned to the Soviet Union, only to see experiments in Georgia to use monkey sperm in human volunteers similarly fail. [Link]

Sick, sick, sick. Nothing is going to convince me that they were really “volunteers.” I wondered if Stalin may have been inspired by Hanuman’s story. He is after all the mightiest of warriors and proved himself during the Ramayana War. He was conceived more naturally…well sort of.

Whether ‘tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them?

Mama Beeb reports that India is putting together an ayurpedia to fight inappropriate patents in developed countries (via Slashdot): Claim: 80% of U.S. patents on medicinal plants by 2000 were of Indian origin

In a quiet government office in the Indian capital, Delhi, some 100 doctors are hunched over computers poring over ancient medical texts… One of them is Jaya Saklani Kala, a young ayurveda doctor, who is wading through a dog-eared 500-year-old text book for information on a medicine derived from the mango fruit…. putting together a 30-million-page electronic encyclopædia of India’s traditional medical knowledge…

Dr Vinod Kumar Gupta, who is leading the traditional wealth encyclopaedia project… reckons that of the nearly 5,000 patents given out by the US Patent Office on various medical plants by the year 2000, some 80% were plants of Indian origin… … in most of the developed nations like United States, “prior existing knowledge” is only recognised if it is published in a journal or is available on a database…

Mogambo is displeased

The ambitious $2m project, christened Traditional Knowledge Digital Library, will roll out an encyclopaedia of the country’s traditional medicine in five languages - English, French, German, Japanese and Spanish - in an effort to stop people from claiming them as their own and patenting them. The electronic encyclopædia, which will be made available next year, will contain information on the traditional medicines, including exhaustive references, photographs of the plants and scans from the original texts…

… ayurvedic texts are in Sanskrit and Hindi, unani texts are in Arabic and Persian and siddha material is in Tamil language… there are some 54 authoritative ‘text books’ on ayurveda alone, some thousands of years old… [Link]

For today’s Science Friday I wanted to talk about crap. Dinosaur crap that is. About two years ago I came across the word “coprolite” in a paper I was reading. I have a bookmark set to Dictionary.com so I tend to look up many words throughout the day (mostly because unlike most desis I am a shockingly poor speller). To my surprise “corpolite” was yet another name that humanity has provided for feces:

The Indus Valley Civilization could have used a few of these

cop·ro·lite n.
Fossilized excrement. [Link]

Well okay then. I am quite sure several of you will be sharing this new knowledge with someone tonight. You see, corpolite is a paleontologist’s dream. Not only can you figure out if the animal that “dropped” it was a carnivore/herbivore/omnivore, but you can also tell which plants existed at the time. An article in the Journal Science today is titled, “Dinosaur Coprolites and the Early Evolution of Grasses and Grazers,” and has Dr. Vandana Prasad of Lucknow as the first author (paid subscription required):

Silicified plant tissues (phytoliths) preserved in Late Cretaceous coprolites from India show that at least five taxa from extant grass (Poaceae) subclades were present on the Indian subcontinent during the latest Cretaceous. This taxonomic diversity suggests that crown-group Poaceae had diversified and spread in Gondwana before India became geographically isolated. Other phytoliths extracted from the coprolites (from dicotyledons, conifers, and palms) suggest that the suspected dung producers (titanosaur sauropods) fed indiscriminately on a wide range of plants. These data also make plausible the hypothesis that gondwanatherian mammals with hypsodont cheek teeth were grazers.

Translate to English please: this means that ~70 million years ago a lot of really large dinosaurs were grazing on grass all over the chunk of land that eventually broke away from the supercontinent Gondwana to become the Indian sub-continent (before it once again recombined like the present day). We can always rely on good old National Geographic to break it down for the laymen:

Coprolites are very common in the area and are often found in rocks that have been worn down by weather. Based on their common association with titanosaur bones, many of the dung fossils probably come from the massive plant-eating reptiles.

The finding is the first indication that grasses evolved before the dinosaurs went extinct.

Fossil evidence had suggested that grasses evolved along with early plant-eating mammals. Hoofed animals with high-crowned teeth suitable for chewing grass first began to appear about 25 million years ago.

But the grass minerals in the Indian coprolites were much older than the hoofed mammals and were already diverse. Five different species were evident, which means that grasses likely diversified substantially before the end of the late Cretaceous.

Imagine that. Dinosaurs were doing almost the same job millions of years before the sacred cow began eating grass all over India (and tilling the fields), thus sustaining the Indus Valley Civilization. This immediately caused me to imagine a Flintstones type universe in which the dinosaurs may have gone on to become sacred, if only they had survived extinction and been domesticated.

Bubble boy Ram Sabnis helped an inventor complete his decade-long quest to create a new kids’ toy: the first bubbles with disappearing color, so they won’t stain your kids or your floor (see photos). Like sticky notes, their impermanence is their selling point (via Boing Boing). I knew that textile industry would come in handy someday!

Ram Sabnis is a leader among a very small group of people who can point to a dye-chemistry Ph.D. on their wall. Only a handful of universities in the world offer one, and none are in the U.S. (Sabnis got his in Bombay). He holds dozens of patents from his work in semiconductors (dying silicon) and biotechnology (dying nucleic acids)…

Sabnis told them he’d have it ready to market in a year… “This is the most difficult project I have ever worked on,” Sabnis says now… For months, he ran 60 to 100 experiments a week, filling notebooks with sketches of molecules, spending weekends in the library studying surfactant chemistry, trying one class of dyes after another…

He synthesized a dye that would bond to the surfactants in a bubble to give it bright, vivid color but would also lose its color with friction, water or exposure to air… go away completely, as though it had never been there. When one of these bubbles breaks on your hand, rub your hands together a few times and look: Poof. Magic. No more color… [Link]

For today’s Science Friday, I want to jump right into the center of the culture wars. From Tuesday’s elections, two results in particular will affect the way that science is taught in parts of our country. First, the Kansas Board of education voted 6-4 to weaken evolution teaching in its classrooms. Second, voters in Dover, PA swept eight pro-Creationist school board members out of office and replaced them with eight anti-creationists.

The Kansas Board of Education has approved science standards that support the theory of intelligent design and cast doubt on Darwin’s theory of evolution. The final vote was 6-4 in favor of intelligent design. [Link]

Voters in rural Dover, Pennsylvania, on Tuesday ousted eight school board members who favor mentioning the concept as an alternative to evolution. The newly elected board members are opponents of the concept, which critics say promotes the Bible’s view of creation and violates the constitutional separation of church and state. [Link]

The latter action prompted this from good ‘ole Pat Robertson:

Conservative Christian broadcaster Pat Robertson told citizens of a Pennsylvania town that they had rejected God by voting their school board out of office for supporting “intelligent design” and warned them Thursday not to be surprised if disaster struck…

“I’d like to say to the good citizens of Dover: if there is a disaster in your area, don’t turn to God, you just rejected Him from your city,” Robertson said on his daily television show broadcast from Virginia, “The 700 Club” [Link]

This week’s Time magazine features a very clear and concise appeal from commentator Eric Cornell, calling all scientists to action:

…as exciting as intelligent design is in theology, it is a boring idea in science. Science isn’t about knowing the mind of God; it’s about understanding nature and the reasons for things. The thrill is that our ignorance exceeds our knowledge; the exciting part is what we don’t understand yet. If you want to recruit the future generation of scientists, you don’t draw a box around all our scientific understanding to date and say, “Everything outside this box we can explain only by invoking God’s will.” Back in 1855, no one told the future Lord Rayleigh that the scientific reason for the sky’s blueness is that God wants it that way. Or if someone did tell him that, we can all be happy that the youth was plucky enough to ignore them. For science, intelligent design is a dead-end idea.

My call to action for scientists is, Work to ensure that the intelligent-design hypothesis is taught where it can contribute to the vitality of a field (as it could perhaps in theology class) and not taught in science class, where it would suck the excitement out of one of humankind’s great ongoing adventures.

Earlier this week The Discovery Channel handed out awards for its 2005 Discovery Young Scientist Challenge. Who took ‘America’s Top Young Scientist of the Year’ award? Meet Neela Thangada of San Antonio, TX. From Rediff.com:

Neela, of San Antonio, Texas, was adjudged ‘America’s Top Young Scientist of the Year’ — which carries a $20,000 scholarship - for her science project on plant cloning.

…student of Keystone Junior High School, won the top prize for her science fair project titled ‘Effects of Various Nutrient Concentrations on the Cloning of the Eye of Solanum Tuberosum at Multiple Stages.’ Her skills of leadership, teamwork, scientific problem solving, critical thinking, and oral and written communication skills earned her the title of ‘America’s Top Young Scientist of the Year’, organisers say.

“I am very excited and happy to win this prize,” Neela told rediff India Abroad. “I did not expect to win, so it was a shock to me.” She said the contest is a great programme, which helps students get interested in science and take that interest to the next level. She plans to continue research at her high school, with the ultimate goal of becoming a professor of medicine.

Neela’s research was inspired by a biology textbook’s idea of a potato cloning experiment. She wanted to determine how different nutrient concentrations affected the multiple stages of growth in a potato. In her experiment, she removed 60 shoot tips from growing potatoes.

After sterilizing the tips, she excised the bottom two segments, and placed each in a test tube of half-strength or full-strength nutrient solution before incubating them.

Cloning? I don’t think they look favorably upon cloning in conservative Texas. It’s great to see that Indian parents are now allowing their kids aspire to be a professor of medicine and not just common doctors . Nine of the forty finalists were in fact of South Asian origin. Second place went to Nilesh Tripuraneni of Fresno, CA:

Nilesh had heard about hydrogen-powered cars but understood that producing hydrogen requires fossil fuels. He sought to find a more environmentally friendly approach through solar hydrogen production.

Nilesh built a solar-powered device that ran an electric current through a beaker full of saltwater. The result: electrolysis, by which water is split into hydrogen and oxygen. By clever manipulation of various gas laws, Nilesh measured the temperature, pressure, and volume of the hydrogen gas produced. He found that seawater produced almost as much hydrogen as solutions containing sulfuric acid or sodium hydroxide. [Link]

That there is an engineer in the making folks.

I sometimes hang out at Brad DeLong’s blog, where apparently Razib thought I was a dude. Yesterday DeLong wrote a post about Tamiflu, the Roche patented drug which is the one of the only plausible defenses against the dreaded Avian influenza or Asian Bird Flu. DeLong was mostly concerned with the domestic policy and economic ramifications of nationalizing a patent in times of emergency and stockpiling a drug ahead of time, but as with Sepia Mutiny, the comments can be most educational—and that’s how I found out that clever Cipla is at its Robin Hood reverse engineering tricks again. Bird flu is, of course, a global issue:

Cipla, an Indian producer of generic drugs, is preparing to become an alternative producer of oseltamivir phosphate, an antiviral drug better known by the brand name Tamiflu.Cipla plans to offer Tamiflu in the Indian market and in 49 less-developed countries where the company already sells AIDS treatments, Hamied says. The legality of the introduction in India, where pharmaceutical patents started to be recognized this year, is uncertain.

Hamied says he will withdraw Tamiflu from the Indian market if Roche’s patent is recognized.  (Link.)

A Roche spokesman, Terry Hurley, said that the company ”fully intends to remain the sole manufacturer of Tamiflu.” . .Making the drug involves 10 complex steps, he said, and the company believes that it’ll take another company ”two to three years, starting from scratch,” to produce it. Hamied dismissed that claim, saying that he initially thought it would be too hard but that his scientists had finished reverse-engineering the drug in his laboratories two weeks ago. He said he could have small commercial quantities available as early as January 2006. Asked if he thought Hamied was making an idle boast, Hurley declined to comment. Hamied said he would sell generic Tamiflu ”at a humanitarian price” in developing nations and not aim at the US or European market. ”God forbid the avian flu should strike India,” he said. ”There is no line of defense.” (Link.)

What does this have to do with mangosteens? I’m glad you asked!

I was thinking of starting up “Science Fridays” here on SM.  Let’s face it, there are a lot of science geeks and engineers that read SM on a daily basis who aren’t being catered to.  I think our long term growth strategy should include reaching out to this key demographic.  Why Friday?  Two reasons.  First, the two most prestigious peer-reviewed journals Science and Nature are reported on in the media on Fridays (though they usually come out on Thursday).  More importantly however I usually have more time to blog on Fridays (the rest of the week I am busy doing science-geek things).   This being SM I will of course look for the desi connection in science stories.  So without further pomp here we go.  This week’s theme will be Cryptozoology.  The first story I bring you is a tip from SM reader Marvin Thomas who writes to us about something that washed up on a beach in Tamil Nadu recently because it was supposedly dislodged by the Tsunami from months ago.  First watch the following clip [via Giantology]:

If you remember, Vinod blogged about ancient ruins that were uncovered as a result of the Tsunami.  This creature was supposedly buried close by.  But according to the “reporter” Rupa Sridharam in this “news clip” the bones of this creature just washed up/was unburied now.  Luckily SM has a paleontologist on staff to definitively tell you that this is a hoax.  Even if you can’t see the fake special effects it’s obvious that whoever filmed this doesn’t know the first thing about science.  First off they sent in archeologists to do a paleontologist’s job.  I HATE it when people mess stuff like this up.  Remember Top Gun?  Kelly McGillis’s character was described as a “civilian astrophysics instructor.”  Why the hell would someone that specialized in stars and globular structures be sent in to teach test pilots?  That’s just stupid.

Currently Snopes.com has this case (hoax or not) categorized as “undetermined.”

It’s probably safe to say that the clip itself is not a genuine news report, as no other news outlets have reported on this amazing find. We don’t yet know the source of the video — it could be something taken from a television or film drama, a viral promo for some type of upcoming entertainment offering (such as a video game), or just something created for the sake of perpetrating an amusing hoax.

Every Geologist has the same macabre dream.  They want to be as close to the fault as possible when the big one hits.  Any geologist that tells you different is lying so as not to upset your sensibilities.  The first three months of this year I spent nearly every weekend camping in the rugged mountains near the San Andreas Fault while constructing a geological map of the area.  On every drive out the professor would smile devilishly and then say “maybe the Big One will hit this weekend.”

Previously I blogged about the extreme dangers of the world’s most unforgiving battlefield, high in the Siachen Glacier near the Line of Control in Kashmir (Manish followed up with some stats).  As if the hail of artillery rounds, machine-gun fire, and extreme cold weren’t enough, over the weekend the soldiers manning their outposts had to deal with a massive Earthquake almost directly beneath them.  How did those soldiers fair during the Earthquake?  That is a secret held close by both sides for good reason.  What men with guns can’t dislodge, an Earthquake can manage with ease.

ISLAMABAD: The Army General Headquarters has asked the Ministry of Water and Power to restore power to several sensitive military installations, which collapsed in the earthquake, along the Line of Control (LoC) in Azad Jammu and Kashmir (AJK), a government official told Daily Times.

The Water and Power Development Authority (WAPDA) was providing electricity to AJK from the Muzaffarabad Grid Station through a single point electricity provision system, while AJK Electricity Board was responsible for power distribution in the area.

The official said that the Muzaffarabad Grid Station supplied electricity to all sensitive military installations and pickets, but the earthquake has completely destroyed the system. [Link]

and on the Indian side:

Twenty-six security personnel, including 21 Army jawans, were killed and scores of others injured as the massive earthquake damaged bunkers and barracks along the Line of Control (LoC) in Baramulla, Kupwara and Poonch districts of Jammu and Kashmir today.

The Army has lost 21 soldiers due to bunkers caving in and damage to barracks along LoC in Rampur, Uri, Baramulla and Tangdhar sectors, a defence spokesman told PTI. [Link]

Mahatma Gandhi may never have won a Nobel, but Gauri Nanda makes it all ok.

The Ig Nobels are the Hasty Puddings of the science world. They’re given out for the most pointless or humorous scientific research, like one winning paper on how leeches react to beer and sour cream. (Like humans, I’m guessing they swell up and die.)

Nanda won last night for her annoying, you-must-get-out-of-bed alarm clock. She’ll make a perfect desi mom someday Congrats, Gauri!

ECONOMICS: Gauri Nanda of the Massachusetts Institute of Technology, for inventing an alarm clock that runs away and hides, repeatedly, thus ensuring that people DO get out of bed, and thus theoretically adding many productive hours to the workday.

The 2005 Ig Nobel Prizes were awarded on Thursday evening, October 6, at the 15th First Annual Ig Nobel Prize Ceremony, at Harvard’s Sanders Theatre… [Link]

Note that last night was their 15th ‘First Annual’ ceremony, like it’s my friends’ tenth 21st birthdays  Here’s more on Nanda. Past South Asia-related winners:

MATHEMATICS: K.P. Sreekumar and the late G. Nirmalan of Kerala Agricultural University, India, for their analytical report “Estimation of the Total Surface Area in Indian Elephants…”

PHYSICS: Deepak Chopra of The Chopra Center for Well Being, La Jolla, California, for his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness. [REFERENCE: Deepak Chopra’s books “Quantum Healing,” “Ageless Body, Timeless Mind,” etc.]…

PEACE: Lal Bihari, of Uttar Pradesh, India, for a triple accomplishment: First, for leading an active life even though he has been declared legally dead; Second, for waging a lively posthumous campaign against bureaucratic inertia and greedy relatives; and Third, for creating the Association of Dead People…

A fascinating article from a science blog I read from time to time - 

This year’s Nobel Prize in medicine or physiology was announced this morning. Barry Marshall and J. Robin Warren won for discovering that ulcers can be caused not by stress or genes but by a bacterium called Helicobacter pylori (shown here)

…Helicobacter infects half of all people on Earth…The scientists documented a surprising variety of genes in the bacteria. Each ethnic group they looked at carried a distinctive strain.

As scientists got to know the global variation of Helicobacter better, they began to discover a remarkable pattern. They mapped out an evolutionary tree of the strains of the bacteria and found that it lined up very well with the migrations of humans over the past 50,000 years. One study looked at the Ladakh province of northern India. Muslims and Buddhists have coexisted there for 1000 [years] but remain isolated from one another. It turns out that Muslim Ladakhs only carry a European strain of Helicobacter, while Buddhists carry a mix of European and East Asian bugs.

They might be neighbors, but that don’t mean they’re friends.

The late American astronaut Kalpana Chawla is the subject of the newest comic book (or graphic novel) in the Amar Chitra Katha series (thanks for the tip Cecilia).  The BBC reports:

The life and achievements of an Indian-American astronaut who died in the Columbia space shuttle disaster in 2003 has now been illustrated in comic form.

An Indian publishing house has released the comic book based on Kalpana Chawla, the first American female astronaut of Indian origin to have gone on a National Aeronautics Space Administration (NASA) mission…

“If Kalpana Chawla inspires even two more students to go out there and achieve what they are dreaming for, well, then that’s our job done really,” she said.

About 437 titles have been released under the comic series and 90 million copies sold.

That should be an interesting read.  I am curious as to how much fiction might be added into her real story to play to the young Indian audience that is most likely to pick up this book.  Likewise, I want to see how much nationalism might be displayed by the comic book character.  Bottom line though is whatever gets young kids interested in space and science is good to see.

Fifteen-year old Meghna Pithadia says her ambition is to become an astronaut.

She says a comic on Chawla’s life is a great way of introducing her to small children.

“They can come to know about her, what was her life, what was her history. It’s a good thing, they can learn from her.”

Nine-year old Sakina Machiswalla said she read a little of the comic book and realised that girls can do everything that boys can do.

“She wanted to become an astronaut and she went out there and became one. If boys can do it then so can girls. Now I have a goal that I must do something big in life.”

Now here’s a topic that’s guaranteed to make folks squirm.   A group of Brit scientists think they’ve discovered the root cause of their country’s recent bout with Mad Cow disease.   Cynics, upon hearing the proposed theory, might argue that this whole thing amounts to a massive deflection of blame to the brown nether world -

LONDON - Mad cow disease may have originated from animal feed contaminated with human remains washed ashore after being floated downriver in Indian funerals, British scientists said on Friday.

…Professor Alan Colchester of the University of Kent in England says it may have been caused by the tons of animal bones and other tissue imported from India for animal feed which also may have contained the remains of humans infected with Creutzfeldt-Jakob disease (CJD).

…In a report in the Lancet medical journal, Colchester and his daughter Nancy, of the University of Edinburgh, explained that many human and animal corpses were disposed of in rivers in India in accordance with Hindu custom.

The remains washed ashore in poor areas where bone collectors work.

“We are aware of a considerable risk of the incorporation of human remains with the animal remains that are collected. They are processed locally and some have been exported. In 10 years, more than a third of a million tons of material from these areas was imported into the UK,” Colchester said.

Needless to say, other scientists advise that these are waters upon which one should tread lightly -

“Scientists must proceed cautiously when hypothesizing about a disease that has such wide geographic, cultural and religious implications,” Shankar said.

Your old, crazy aunty from back in da homeland may have found yet another way to haunt her Western son from beyond the grave.    

[Hi folks, this is my last Sepia Mutiny post. It's been fun, but it was a one-month guestblogger gig all along (same deal with Turbanhead). I've really enjoyed playing in this sandbox, and doing comments gupshup w/people like Bong Breaker, Punjabi Boy, DesiDancer, Razib the Atheist, Al-Mujahid for Debauchery, etc. etc. Feel free to come play in my smaller, geekier box over here. Ciao, and I leave you with a short post on bioethics, just in case "Versions of the Ramayana" wasn't punk enough for you]

Surprisingly, though India is in some ways an even more religiously polarized place than the U.S., the question of the ethics of this kind of biotech (as well as the ethics of genetic cloning) has not become a bone of political contention. This is despite the fact that passages in Hindu scriptures like The Mahabharata clearly suggest that life begins at conception:

Indeed, most evangelical Christians, who believe that the embryo is a person, may find more support in ancient Hindu texts than in the Bible. Many Hindus see the soul -- the true Self (or atman) -- as the spiritual and imperishable component of human personality. After death destroys the body, the soul soon finds a new temporal home. Thus, for Hindus as much as for Catholics, life begins at conception.

The ancient system of Indian medicine known as Ayurveda assumes that fetuses are alive and conscious when it prescribes a particular mental and spiritual regimen to pregnant women. This same assumption is implicit in The Mahabharata, the Hindu epic about a fratricidal war apparently fought in the first millennium B.C. In one of its famous stories, the warrior Arjuna describes to his pregnant wife a seven-stage military strategy. His yet-to-born son Abhimanyu is listening, too. But as Arjuna describes the seventh and last stage, his wife falls asleep, presumably out of boredom. Years later, while fighting his father's cousins, the hundred Kaurava brothers, Abhimanyu uses well the military training he has learned in his mother's womb, until the seventh stage, where he falters and is killed.

A couple of days ago the New York Times had an interview with Dr. Ullas Karanth, a wildlife biologist/conservationist from India who is desperately trying to save the tiger from extinction (thanks for the tip Yamini):

Dr. Karanth, 57, was in New York on a recent summer afternoon to attend a conference at the Bronx Zoo, a subsidiary of the conservation society, on the future of tigers in the wild. In a break in the proceedings, he spoke of his favorite feline.

Q. Do we know how many wild tigers still exist in India?

A. We don’t. The government claims that there are over 3,000. But that figure is based on a flawed counting method that officials developed for themselves. There are preservation groups who claim the number is more like 1,000. It’s probably not that low.

We believe that if India is to have tigers, these wildlife reserves must be rigorously protected.

Josh Dolan of Cornell University publishes a paper in this week’s Nature (paid subscription required) that proposes a solution for animals faced with the same prospects as the tigers in India:

North America lost most of its large vertebrate species — its megafauna — some 13,000 years ago at the end of the Pleistocene. And now Africa’s large mammals are dying, stranded on a continent where wars are waging over scarce resources. However much we would wish otherwise, humans will continue to cause extinctions, change ecosystems and alter the course of evolution. Here, we outline a bold plan for preserving some of our global megafaunal heritage…

Our vision begins immediately, spans the coming century, and is justified on ecological, evolutionary, economic, aesthetic and ethical grounds. The idea is to actively promote the restoration of large wild vertebrates into North America in preference to the ‘pests and weeds’ (rats and dandelions) that will otherwise come to dominate the landscape. This ‘Pleistocene re-wilding’ would be achieved through a series of carefully managed ecosystem manipulations using closely related species as proxies for extinct large vertebrates…

Bold plan?  Are you kidding me! You guys get what he is saying?  They want to reintroduce lions and tigers and…elephants from Africa into North America so that they have a chance to survive the seemingly inevitable extinction they face in Africa (and most likely India).  This is just ballsy.  There are a dozen reasons why this is a very very bad idea but I like big thinkers.

Some of the comments on SM of late have disturbed me greatly.  I am begining to realize that a lot of people are very confused about who they are.  Even worse they seem obsessed with trying to convince people who they are not.  While sitting in a jury pool all day last Tuesday I did a little bit of reading.  I learned of National Geographic’s Genographic Project which attempts to trace the path of humans as they left Africa.

[Spencer] Wells, 36, is a population geneticist using science in global pursuit of the greatest story not yet told: the story of how humankind traveled from its origins in Africa to populate the planet. The most telling clues lie with isolated, indigenous tribes like the Tubu, for their DNA remains, in a sense, the purest. Their unique genetic markers, characteristic mutations in a defined sequence of DNA, are like flags waving from the place their ancestors have inhabited for thousands of years—the starting point for ancient migrations. Any venturesome Tubu who crossed the Sahara to see the outlying world, and propagated in the process, passed on one or another of those genetic markers to his or her offspring. Any traveler who came through the Tibesti and intermarried did the same. Wells might take a cheek swab from an investment banker in Boston and find that same genetic marker: proof that one of those Tubu created a family line that leads, in some circuitous way, over continents and generations, from the Tibesti to an oak-paneled office in Back Bay. It’s in the hope of tracing myriad journeys such as this that Wells, a newly named National Geographic Explorer-in-Residence, is undertaking one of the most ambitious and expensive research adventures in the National Geographic Society’s 117-year history: the grandly named Genographic Project.

At a cost of 40 million dollars over five years, the brunt of it borne by National Geographic, IBM, and the Waitt Family Foundation, the Genographic Project under Wells’s direction is establishing 11 DNA-sampling centers around the world, with the goal of collecting 100,000 cheek swabs or blood samples from mostly indigenous peoples like the Tubu. A sense of urgency infuses the project: Year by year, at an ever quickening rate, the outside world is crowding in on, and at the same time absorbing, indigenous peoples. A Tubu who moves to Paris will still have the genetic markers that distinguish him as a Tubu, but the geographical context for his markers will be gone. As for the Tubu who remain in the Tibesti mountains, they may marry more with outsiders as modern technology makes contact more likely. Generation by generation, tracing the last routes of historical migration of such isolated people grows that much harder. Wells wants to map as many routes as he can while their geographical origins are relatively intact.

When I worked for a few months in Delhi at the end of 2002 I was pleasantly surprised by my daily commute. I had heard that the Delhi air was absolutely choked with automobile exhaust fumes and made commuting unbearable. Having converted many buses and rickshaws over to natural gas (CNG) seemed to have done a pretty good job in cleaning up the Delhi skies. Los Angeles, where I live, is still playing catch-up. In the near future though, Indian cities may surge ahead again thanks to the most reliable form of transportation. Indianexpress.com explains:

The great Indian autorickshaw may have just shifted to the eco-friendly CNG but it’s ready for the generation-next fuel.

Taking a major leap towards Indo-US co-operation in the energy sector, the United States Department of Energy (DOE) and US Agency for International Development (USAID) have helped develop a hydrogen-run three-wheeler for Indian roads.

The Rochester Hills (Michigan)-based Energy Conversion Devices (ECD) has successfully converted and developed a CNG-run three-wheeler of Bajaj Automobiles into one run on hydrogen fuel.

Converting over to a hydrogen economy in the U.S. would be a massive undertaking that would span a couple decades. Some analysts think that China and India who have a smaller oil infrastructure could make the switch more easily, and also become more competitive economically, if they start with an alternative energy source while their economies are still developing. I know the critics will say that a hydrogen economy is pie in the sky but I’ve always had a saying: If it’s good enough for the Space Shuttle then its good enough for me (Tang and Velcro included).

Seven years ago I spent a few days on the island of Capri, off the coast of Italy. At the top of the island was a famous hostel where everyone who visits ends up staying. My friends and I got lost trying to find it. Out of nowhere came a very old man who led us down twisting paths, first to a view of the Italian coast and then on to the hostel. I couldn’t help notice that this man, despite being old and short in height, was incredibly fit. His arms were like tree trunks and he moved with the agility of a mountain goat. I decided right then that this was the musculoskeletal system that I wanted when I became an old man. This feeling overcame me again, years later on the Inca trail where the Quechua porters (some quite old) made us a look like pathetic weaklings. If anyone has seen the Motorcycle Diaries they will recall the scene where Che and his buddy are forced to crash out on the Inca trail, just as a Quechua guide runs by them.

Earlier this week NPR had a fun story (MUST listen) about an article that appeared in the June 17th issue of the Journal Science. The paper is titled, Energetics of Load Carrying in Nepalese Porters, by Bastien et. al. [paid subscription required].

Nepalese porters routinely carry head-supported loads equal to 100 to 200% of their body weight (Mb) for many days up and down steep mountain footpaths at high altitudes. Previous studies have shown that African women carry head-supported loads of up to 60% of their Mb far more economically than army recruits carrying equivalent loads in backpacks. Here we show that Nepalese porters carry heavier loads even more economically than African women. Female Nepalese porters, for example, carry on average loads that are 10% of their Mb heavier than the maximum loads carried by the African women, yet do so at a 25% smaller metabolic cost.

Come on. You can’t possibly read that and not want a body like that!

In Egypt, near the ancient city of Alexandria, in the year 1911, on a day in late June, an event occurred that you won’t find in most history books. Those who give their lives in the pursuit of science are never as remembered as those who die during the waging of war. Human society may never properly evolve until such wrongs are corrected.

It was approximately 9a.m. in the morning and our forgotten hero had probably just gone out for a walk or finished sniffing some butts. Suddenly, from the morning sky fell 10 kilograms of rock that had broken up into several pieces as it fell through the thick atmosphere of our planet. Scientists later recovered approximately 40 total pieces. One of these rocks struck our hero, the dog, and killed it. To date it is the only mammalian fatality ever recorded at the hands of a meteorite. The dog’s true sacrifice wasn’t fully appreciated until it was discovered that the meteorite was actually a chunk of the planet Mars. The meteorite was named “Naklha”, in honor of the region in which it landed. The dog’s name is a casualty of history. Millions of years earlier the meteorite had been a basaltic rock that had been blown off the surface of Mars at escape velocity, when a larger meteorite had impacted Mars. It was propelled into a heliocentric orbit where it lingered for several millions of years. The irresistible attraction of gravity finally pulled it towards Earth, and its fatal encounter with our dog. Studying the meteorite and comparing it to data streaming back from Mars, beginning with the Viking Mission in 1976, has helped us to unravel many of the secrets of the Red Planet. If you think that I am making all this up and simply suffering from another delusion, then feel free to look it up.

Although the above story has only the most tenuous link to the following one, I just felt it was a story that needed to be told. OutlookIndia.com reports:

…NASA has given Indian names to certain types of rocks on Mars, a senior planetary geologist at the space agency’s Mars Mission said today. “…NASA has given Indian names to a number of rocks. We shall disclose the names soon after NASA gives a clearance to make this classified information public,” NASA planetary geologist Amitabha Ghosh, currently on a three-city tour to India, told PTI today.

Ghosh said the rocks were named in consultation with Indian geophysicists and astrophysicists.

For the first time, a four-member team from NASA, including planetary geologists Ghosh, Dr Michael Wyatt, astrogeologist Dr James Rice and Dr Nicole Schultz are in India to further space science research.

“The idea is to hold talks at scientific organisations and planetaria to create awareness about space science research,” Ghosh, the only Asian on the mission, said.

As members of the Mars Explorer Rover Mission, the four have been witness to the activities of Spirit and Opportunity rovers that landed on Mars.

Of course this is just a publicity and excitement building stunt. There are countless rocks on Mars. Giving some Indian names isn’t that big a deal. More importantly the team has created a website called Tharsis India to further awareness of Mars exploration in India. The Tharsis region on Mars is known for its supermassive volcanoes.

The visit to India comes at the same time as the Paris Airshow where NASA mentioned that it is shooting for after 2015 to put humans back on the Moon.

As Abhi posted, Amal Dorai of MIT threw a party for time travelers last Saturday. He begged visitors to bring a cure for cancer or some other proof of their travels. Here’s a report from Afua, the Samoan particle physicist-slash-bouncer:

“Two surfer dudes named Bill and Ted showed up claiming to be from the year 1989. I asked them to prove it, but all they said was ‘way!’ and ‘bogus.’ So I threw ‘em out. They yelled ‘Party on, dudes!’ and disappeared into a phone booth.

“A crazy-eyed old man with Van der Graaf hair showed up in a DeLorean. I ejected him, and he peeled out at 88 mph stuffing garbage scraps into a blender.

“Some huge thug showed up in a monster suit. He gave his name as Moore Locke, shrieked loudly and bit someone’s head off.

“A tall, thin man with pointy ears wandered by muttering something about a whale.

“A guy named Spicoli showed up stoned out of his mind. ‘Dude, I’m, like, from 30 seconds in the past,’ he said, adding, ‘huh-huh-huh.’

“So there were no time travelers at the party.”

By the end of the party, the only confirmed time travelers were Dorai’s purple leisure suit and zebra-stripe shirt. No other travelers showed up, so the party was a bust. The MIT boys squabbled over the only female-like creature in the room, a girl from BU who took a wrong turn and got trapped in Morss Hall like a dinosaur surrounded by velociraptors. Thousands of years later, they will find her bones.

If I wasn’t a broke ass graduate student I’d be on a flight to Boston tomorrow morning. “Why,” you ask? The Guardian says it all [tip from Francis Assisi]:

One of the strongest arguments against time travel is that we are not overrun with curious tourists from the future. A university student in Boston plans to change that, by inviting budding Doctor Whos to the world’s first time traveller convention this weekend.

The organiser, Amal Dorai - a masters student in electrical engineering and computer science at the Massachusetts Institute of Technology - aims to test the theory of time travel by inviting people from the future to the event.

This is friggin awesome! Dorai’s hypothesis seems to me to parallel the Fermi Paradox which asks why we haven’t been overrun by intelligent beings from elsewhere in the galaxy yet.

“We are doing this as a very low-risk, low-cost way to investigate the possibility of time travel,” he said. “I think the probability they will come is very low, but if it does happen it will one of the biggest events in human history.

“Of course, no time travellers doesn’t rule out the possibility of time travel, they could have just decided not to come to our convention.”

Ahhh…hope. The last refuge of the nerd. Incidentally there was a Star Trek the Next Generation episode years ago where a time traveler from the past pretended he was a time traveler from the future. No word yet on how Dorai plans to handle this possibility. If we were to teach a time traveler from the past too much, he/she could pollute the timeline. It’s enough to make your head spin.

With Edison, NJ in the news, this article from the the good folks over at GNXP is rather timely - a mathematical model for the formation of ethnic enclaves -

...Natural Intelligence has developed an application called the "Ethnic Simulator" that models the residential behavior of people in the hypothetical ethnically diverse city of Metropolis.

...The premise of the Ethnic Simulator is that ethnically distinct groups have a modest preference to live among their own kind. In Metropolis there are five ethnic groups –- Blues (the majority), Greens, Reds, Grays, and Yellows. The application allows the user to set the percentage of preference of each group for its own kind.

Outcome? Regardless of how "racist" the majority Blues are, the minority Yellows end up in "ghettos" if they express even the most minor preference for being near each other.... Intuitively obvious perhaps, but interesting to see mathematically modelled.

Eccentric mathematics rock star Srinivasa Ramanujan, who died at age 33, postulated a combinatorics problem almost 100 years ago that’s just been solved (via Slashdot). The breakthrough may yield better cryptography, meaning more secure documents and transactions.

Any integer can be broken down into sums of smaller numbers (‘partitions’). A University of Wisconsin researcher has extended Ramanujan’s theorem and shown that the number of partitions in any large integer are divisible by all prime numbers.

The truly interesting bit is Ramanujan’s Indian Idol story. He was recruited to Cambridge from an underdeveloped farm system like a pitching prodigy from Puerto Rico:

… in 1913, the English mathematician G. H. Hardy received a strange letter from an unknown clerk in Madras, India. The ten-page letter contained about 120 statements of theorems on infinite series, improper integrals, continued fractions, and number theory… Every prominent mathematician gets letters from cranks… But something about the formulas made him take a second look… After a few hours, they concluded that the results “must be true because, if they were not true, no one would have had the imagination to invent them…” [Hoffman]

The next Einstein working alone in a room, surfacing out of nowhere to overturn the accepted paradigm: it’s every institution’s nightmare. The self-taught Ramanujan had flunked out of school in Tamil Nadu and run away from home because he obsessed over math and only math. Over time, he was granted an honorary doctorate by Cambridge and elected to the Royal Society of London, Valhalla for mathematicians.

Ramanujan was an intuitive thinker who disdained formalism:

Hardy was a great exponent of rigor in analysis, while Ramanujan’s results were (as Hardy put it) “arrived at by a process of mingled argument, intuition, and induction, of which he was entirely unable to give any coherent account…” He was amazed by Ramanujan’s uncanny formal intuition in manipulating infinite series, continued fractions, and the like: “I have never met his equal, and can compare him only with Euler or Jacobi.” [Hoffman]

24-year-old Ram Kolli just won the U.S. Memory Championship, quickly memorizing decks of cards, names and faces, poems, and long numbers.

… when Cooke sees a three of clubs, a nine of hearts, and a nine of spades, he immediately conjures up an image of Brazilian lingerie model Adriana Lima in a Biggles biplane shooting at his old public-school headmaster in a suit of armor… To keep all this information in order, memorizers have to link their images together in a chain. Some… use what’s called the “journey method.” They place their images at predetermined points along a route that they know well… When it comes time to recall, he simply takes a mental stroll through his old college town and is able see each of the images in the place where he put it.

Evolutionary selection has favored sharp navigational memory, ranging from ‘dude, where’s my food?’ to ‘dude, where’s my wife?’:

… this method of using visual imagery as a mnemonic device was first employed by a Greek poet named Simonides in 477 BC. Simonides was the sole survivor of a roof collapse that killed all the guests at a large banquet he was attending. He was able to reconstruct the guest list by visualizing who was sitting at each seat around the table. What Simonides had discovered was that people have an astoundingly good recollection of location… this same technique was later used by Roman generals to learn the names of thousands of soldiers in their command and by medieval scholastics to memorize long religious tomes.

Slate has a fascinating followup on memory formation as portrayed in one of my favorite films, Eternal Sunshine of the Spotless Mind:

… some scientists now believe that memories effectively get rewritten every time they’re activated, thanks to a process called reconsolidation… instead of simply recalling a memory that had been forged days or months ago, the brain is forging it all over again, in a new associative context. In a sense, when we remember something, we create a new memory, one that is shaped by the changes that have happened to our brain since the memory last occurred to us. Theoretically, if you could block protein synthesis in a human brain while triggering a memory, you could make a targeted erasure.

India isn't the same place it used to be. Literally.

A seismologist in India says that the country has moved closer to Indonesia due to the massive earthquake which triggered the tsunami in December.

Dr Vineet Gahlaut said that India had shifted a few centimetres eastwards.

The expedition reveals the geographical distance between India and Indonesia - the epicentre of the deadly earthquake - has been reduced by between five metres and 15mm.

The amount of movement depended on the closeness of different areas to the epicentre of the quake, Dr Gahlaut explained. [BBC]

You see? The tsunami has brought the people of India and Indonesia closer together.

The Harvard controversy on whether women’s technical aptitudes are innate:

… [The Harvard president’s] young daughter, when given toy trucks, had treated them as dolls, naming them “Daddy truck” and “baby truck.” But critics dryly observed that men had a longstanding tradition of naming their vehicles, and babying them as though they were humans.

Lt. Neil Prakash:

You can’t beat ol’ Blinkey for armored protection.

I call my baby, Blinkey, ever since she got one of her headlights blown off in Baqubah by an RPG. The RPG had ripped open that little corner of the hull and exposed the depleted uranium armor. She’s taken so much battle-damage that we’re being told she will never return to duty after this deployment… Supposedly, she will be coded out, ripped apart and studied at a lab. If that’s true, that breaks my crew’s hearts. She has taken a pounding and kept her crew alive. She should be bronzed and placed on a concrete slab at Ft. Knox for everyone to see.

Bharat Bhushan, a MechE prof at Ohio State, is studying lotus leaves to fashion better technology. Biomimetic, how poetic — the Sanskrit gurus would approve.

The project was inspired by lotus leaves’ deceiving looks. Although they appear waxy and smooth to the naked eye, the leaves are actually covered with a series of microscopic bumps that prevent water drops from touching their surface… The idea is to use surfaces to eliminate friction between moving parts that can’t be oiled… In a few years, the development could lead to far cheaper [DLP] wide-screen televisions, [microfluidic] chips that can analyze blood samples or windshields that clean themselves…

There's the high tech approach to minimizing tsunami deaths -- a global alert system that tries to predict tsunamis -- and then there's the low tech approach -- mangrove swamps. This should not be a surprise - wetlands are very effective at combatting flooding, for example, far more so than levees and dams. And while it is anthropomorphic to say that "the wetlands are nature's method of protecting people," it is useful to observe that wetlands have preserved many lands and try to cultivate them for that purpose. The Christian Science Monitor reports [snippets only]:

Mr. Selvum says that 172 families were saved from the tsunami in the fishing village of Thirunal Thoppu in India's Tamil Nadu state only because the mangroves are thriving and dense there. He also mentions three other Tamil Nadu villages where damage had been minimized by the aquatic trees. "Every village has more than 100 families, so just think of the number of lives saved," he says.

"Even though the mechanical impact of a tsunami is enormous, and is bound to destroy the first line of mangroves, the water suddenly slows down as it moves farther in," Selvum says.

Just days ago I mentioned that a bunch of wacky conspiracy stories have emerged recently in order to explain the origin of the tsunami. Although this one has nothing to do with the tsunami, it was just too good to pass up. From India Daily:

Kongka La is the low ridge pass in the Himalayas (the blue oval in the map). It is in the disputed India-China border area in Ladakh. In the map the red zone is the disputed area still under Chinese control in the Aksai Chin area. The Chinese held northeastern part is known as Aksai Chin and Indian South West is known as Ladakh. This was where Indian and Chinese army fought major war in 1962. The area is one of the least accessed area in the world and by agreement the two countries do not patrol that part of the border. According to many tourists, Buddhist monks and the local people of Ladakh, Indian Army and Chinese Military maintain the line of control. But there is something much more serious happening in this area.

According to the few locals people on the Indian and Chinese side, this is where the UFOs are seen coming out of the ground, According to many, the UFO underground bases are in this region and both the Indian and Chinese Government know this very well.

Now please keep in mind that UFO stands for “Unidentified Flying Object” and so it doesn’t necessarily equate to aliens, but what else might it be?

Recently, some Hindu pilgrims on their way to Mount Kailash from the Western pass, came across strange lights in the sky. …The pilgrims at that stage started quizzing the Indian border petrol personnel. According to them, the security personnel told them that they are ordered not to allow any one near the area of interest and it is true that strange objects come out from under the ground with amplified and modulated lights. India’s Special Forces and possible visit the area by intelligence agencies.

But why in this area? Is it due to the remoteness, or something else?

This one seems hard to believe but I am sure it will elicit several comments from those gnxp’ers:

Genes may account for more than 40% of such charitable behavior as the massive outpouring of donations following the recent South Asian tsunamis.

A study comparing the social responsibility of identical and non-identical twins showed that genes account for 42% of individual differences in attitudes while common environment accounts for 23% and other factors account for the remainder.

Conducted by Canadian researcher J. Philippe Rushton of the University of Western Ontario, the study also found that genes have a stronger influence on males than females (50% to 40%) while home upbringing has a stronger influence on females (40% to 0%), suggesting that parents may more closely watch the behavior of daughters than of sons.

The 92nd session of the Indian Science Congress is taking place right now in Ahmedabad and the U.S. is hinting at closer cooperation with India in space exploration as reported by IndiaExpress.com:

“India is working on a mission to moon. We are looking at collaborations with India in this,” Dr Lee Morin, Deputy Assistant Secretary for Science at the US Department of State, Bureau of Oceans and International Environment and Scientific Affairs and a NASA astronaut, told reporters in Ahmedabad at the 92nd session of the Indian Science Congress.

“US is also looking at collaboration in the area of telemedicine,” he said.

One of Bush’s main legacy projects will be an ambitious space agenda, including the first steps in a return to the Moon and preparations for a manned mission to Mars (although both will occur long after he has left office and would be subject to the whims of future administrations). The International Space Station was created with the help of 16 countries, of which India was not one. Baby steps like this could pave the way for India to be an active partner in such ambitious undertakings allowing Indian nationalism to be inspired by something other than nuclear weapons. Let us hope though that scientists such as this guy at the SAROUL (Scientific Advance Research of Universe and Life) conference in New Delhi don’t get to participate in space exploration:

When water was there in Mars, there was a definite life; small insects, reptiles and fishes were the natural life, fishes used to live in small, medium and big lakes.

There were no seas or oceans on Mars, only lakes were available, where the river used to end their journey by dropping water, particularly in the big lakes.” Dr. Baldev said.

Ummm. No. That statement is absurdly false on so many levels, and the worst part is that some of the press won’t know any better.

It’s not often that one hears of a government which is mandating an animal’s extinction; then again, India is and has always been a nation of exceptions. Her Central Zoo Authority (CZA) has decided that it is last call for the “cocktail lion”, a hybrid composed of Asian and African lion genes. All 300 of the mixed cats remaining in zoos and safari parks will be sterilised and allowed to die out, since Indian laws and traditions forbid killing them.

The authorities say the hybrid lions have weakened the blood pool of India’s lions and have turned out to be mangy, emaciated and suffering from mental and physical defects…Critics say that the breeding programmes across India were largely unsupervised over the years.

The end result has been a large increase in “cocktail” lions that have been interbred and are genetically weak. The hybrid animals bear characteristics of both species, but are low on immunity and prone to disease. Some are reported to be suffering from tuberculosis.

Zookeepers first experimented with “cocktails” by cross-breeding their Asiatic lions with African lions who were travelling the country in circuses. At places like Chhatbir Zoo in the Punjab, almost 100 of the cats were created during an era when no thought was given to genetics or preserving certain bloodlines. Zookeepers were focused on the short-term; they bred as many animals as possible, to improve exhibitions. Unfortunately, their careless efforts created the exact opposite result;

The (Chhatbir) zoo’s once healthy pride of lions is now no more than a motley collection of disease-prone animals barely able to stand up.

According to zookeepers, almost 45 lions have died over the past three years. “We lost 13 cubs in one go,” remembers wildlife warden Neeraj Gupta. Almost all the deaths occurred because the animals suffered from severe immune deficiency which slows down or prevents healing whenever the animals fall sick or are hurt.

…While the zookeepers do their utmost to treat the animals and keep them as comfortable as possible, there is little they can do for those born paralysed or for others whose open wounds refuse to heal.

BBC NEWS: Feeble roar of the hybrid lions

Describing what is sure to be a highly controversial idea, Science Magazine [paid or institutional access required] publishes an article about a group of scientists who are calling into question whether the Indus script is really even a script, in the traditional sense. Because of the fact that this article will not be accessible by most, I will liberally quote for the benefit of SM readers.

For 130 years scholars have struggled to decipher the Indus script. Now, in a proposal with broad academic and political implications, a brash outsider claims that such efforts are doomed to failure because the Indus symbols are not writing

Academic prizes typically are designed to confer prestige. But the latest proposed award, a $10,000 check for finding a lengthy inscription from the ancient Indus civilization, is intended to goad rather than honor. The controversial scholar who announced the prize last month cheekily predicts that he will never have to pay up. Going against a century of scholarship, he and a growing number of linguists and archaeologists assert that the Indus people—unlike their Egyptian and Mesopotamian contemporaries 4000 years ago—could not write.

That claim is part of a bitter clash among academics, as well as between Western scientists and Indian nationalists, over the nature of the Indus society, a clash that has led to shouting matches and death threats. But the provocative proposal, summed up in a paper published online last week, is winning adherents within the small community of Indus scholars who say it is time to rethink an enigmatic society that spanned a vast area in today’s Pakistan, India, and Afghanistan—the largest civilization of its day.

The Indus civilization has intrigued and puzzled researchers for more than 130 years, with their sophisticated sewers, huge numbers of wells, and a notable lack of monumental architecture or other signs of an elite class (see sidebar on p. 2027). Most intriguing of all is the mysterious system of symbols, left on small tablets, pots, and stamp seals. But without translations into a known script—the “Rosetta stones” that led to the decipherment of Egyptian hieroglyphics and Sumerian cuneiform in the 19th century—hundreds of attempts to understand the symbols have so far failed. And what language the system might have expressed—such as a Dravidian language similar to tongues of today’s southern India, or a Vedic language of northern India—is also a hot topic. This is no dry discussion: Powerful Indian nationalists of the Hindutva movement see the Indus civilization as the direct ancestor to Hindu tradition and Vedic culture.

Water is becoming increasingly scarce, all over the world. In India, perhaps fewer than a third of all Indians have access to "decent sanitation and high quality drinking water." (See V's earlier post on the subject) Nor is this just an Indian problem. Some of Australia's biggest cities, for example, may run dry in just a few years, perhaps as early as 2006.

What is to be done? Well, there is the ancient vedic practice of Shivambu or Amaroli, but despite Morarji Desai's best efforts, drinking one's own urine has not(ahem) gone down well amongst the general population.

But don't despair. In Singapore, they have harnessed the braininess of Brown scientists in the US to produce NEWater!

NEWater is the product of Singapore's new water-treatment system, and it is wastewater that has been purified through advanced synthetic membranes called ZeeWeed. That's right: The crystal-clear NEWater that gushes through the country's faucets isn't gurgling from a mountain spring. Most recently, it was flushed from a toilet. [Salon.com]

This process is the brainchild of Ashok Gadgil:

In December 1992, an outbreak of a new and dangerous strain of cholera began in southeastern India. Within months it had spread into neighboring countries, killing up to 10,000 people. The tragedy inspired Ashok Gadgil, an Indian-born scientist working at the Lawrence Berkeley National Laboratory in California, to look for a new way to purify drinking water. Using science no more complex than the ultraviolet light emitted by an unshielded fluorescent lamp, he built a simple, effective, and inexpensive water disinfection system. Dozens of these systems are now installed around the world.

"At the bare bones, using the simplest engineering, we could disinfect water for half a cent per ton. That's shockingly cheap. You could disinfect water for one person, a full year's drinking supply, for a couple of cents."

Supplesomething forwarded me an interesting NPR piece on Manjul Bhargava, 28, a professor of number theory at Princeton who discusses how the Fibonacci series pops up not just in mathematics but also in the arts.

The Fibonacci series is the set of numbers beginning with 1, 1 where every number is the sum of the previous two numbers. The series begins with 1, 1, 2, 3, 5, 8, 13, and so on. They were known in India before Fibonacci as the Hemachandra numbers. And the ratio of any two successive Fibonacci numbers approximates a ratio, ~1.618, called the golden section or golden mean.

It's long been known that the Fibonacci series turns up frequently in nature. The numbers of petals on a daisy and the dimensions of a section of a spiral nautilus shell are usually Fibonacci numbers. For plants, this is because the fractional part of the golden mean, a constant called phi (0.618), is the rotation fraction (222.5 degrees) which yields the most efficient and scalable packing of circular objects such as seeds, petals and leaves.

Last week, the European Patent Office revoked agricultural conglomerate Monsanto's patent on a variety of Indian Nap Hal wheat, widely used in chapatis because it doesn't rise when baked (via Boing Boing). Indians had cried biopiracy, reacting the way we would if France had patented apple pie (Monsanto is based in St. Louis, Missouri).

The wheat's low gluten content gives it low water absorption and elasticity. One scientist elaborated on how the patent's central claim was not novel:

The Indian wheat patent by Monsanto has lower gluten, which is responsible for its lower elasticity... This is the trait that is the core of Monsanto's patent and it is a trait evolved by farmers breeding in India. Introducing the trait into a cross... is an obvious step any breeder familiar with the art of breeding can undertake. Monsanto's claim is clearly not novel. This is a clear case of piracy of India's indigenous knowledge of breeding and cooking.

Yes, breeding and cooking: the desi core competencies. The patent opposition was filed in conjunction with Greenpeace.

Monsanto denied the patents would be used to block Indian farmers from using their Nap Hal seed. "Indian users can use Nap Hal for chapatis or whatever else, now and just as they've always been used to," McDermott told The Scientist. "The idea that Indian farmers would have to pay royalties to use Nap Hal, that's just inflammatory and ridiculous."

The controversy echoes the neem patent case in 2000. Neem leaves are widely used in ayurvedic remedies. The EPO revoked this patent, held by the U.S. government and W.R. Grace on a neem-based fungicide.

Here is the patent text.

Bio researcher Vamsi Mootha, 33, just won a $500K MacArthur fellowship (via Political Animal). Mootha is an assistant professor at Harvard who researches mitochondrial gene expression to combat disease.

By comparing the protein fingerprints with gene expression databases, more than 100 previously unknown mitochondrial proteins were identified. He used a similar, coordinated approach to identify the gene that causes Leigh Syndrome French Canadian variant, a fatal metabolic disease.  In diseases resulting not from a single gene but the interaction of sets of genes, he introduced a computational method for identifying patterns of gene activity in specific diseases… As importantly, Mootha has pioneered powerful, adaptable computational strategies for mining data collected in laboratories throughout the world, providing an efficient means to hunt down gene interactions that lead to a wide variety of diseases.

The James Logan debate coach won one as well. The Fremont-Newark-Union City area across from San Francisco has desi and Afghan gang problems, so this guy’s in the thick of it.

For 15 years, against long odds, Tommie Lindsey has held together an award-winning speech and debate team at James Logan High School in the blue- collar suburb of Union City. His students frequently defeat well-heeled competitors from elite high schools.

His teams have won four state championships; three James Logan students have been top winners at the national level and 25 at the state level. This year the team has more than 200 students. Ninety percent of Lindsey’s students go on to four-year colleges. Overall at Logan, just one-third of students qualify for the state university systems… In recent years, the team has been featured in a documentary and won a $100,000 award from Oprah Winfrey.

A 200-person debate team is enormous.

You're on the phone with your grandmother, and she wants to know when you're going to produce grandchildren for her and how on earth you can be "dating" the same person for 2 years without any marriage plans. You tell her that these things take time, that people are complicated, and it's hard to know where this is going. You feel morally superior as she clucks disapprovingly. You think, I'm a modern person, and I have science on my side.

Or do you? Well, today the BBC reports that:

People decide what kind of relationship they want within minutes of meeting, a study in the Journal of Social and Personal Relationships said.

"It's almost a self-fulfilling prophecy. We make a prediction about what kind of relationship we could have with a person and that helps determine how much effort we are willing to put into developing a relationship."

The results were the same for people who talked for three, six or ten minutes.

Prof Ramirez said: "That tells you things are happening very quickly. People are making snap judgements about what kind of relationship they want with the person they just met."
