Animals Laughed Long Before Humans

Stefan Lovgren reports in National Geographic News:

As the human brain evolved, humans were able to laugh before they could speak, according to a new study. But here's the punch line: Laughter and joy are not unique to humans, the study says. Ancestral forms of play and laughter existed in other animals long before humans began cracking up.

"Human laughter has robust roots in our animalian past," said Jaak Panksepp, a professor of psychobiology at Bowling Green State University in Ohio. Panksepp has studied rats and found that when they "play," they often chirp—a primitive form of laughter, according to the scientist. In an article to be published tomorrow in the journal Science, he makes the argument that animal laughter is the basis for human joy. In studying laughter, scientists have focused mostly on related issues—humor, personality, health benefits, social theory—rather than laughter itself. New research, however, shows that "circuits" for laughter exist in very ancient regions of the human brain.

As humans have incorporated language into play, we may have developed new connections to joyous parts of our brains that evolved before the cerebral cortex, the outer layer associated with thought and memory. Researchers say that the capacity to laugh emerges early in child development, as anyone who has tickled a baby knows.

The wisdom of heuristic diversity

Cosma Shalizi, whose return to blogging is most welcomed, points to an intriguing article by Lu Hong and Scott Page.

"We introduce a general framework for modeling functionally diverse problem-solving agents. In this framework, problem-solving agents possess representations of problems and algorithms that they use to locate solutions. We use this framework to establish a result relevant to group composition. We find that when selecting a problem-solving team from a diverse population of intelligent agents, a team of randomly selected agents outperforms a team comprised of the best-performing agents. This result relies on the intuition that, as the initial pool of problem solvers becomes large, the best-performing agents necessarily become similar in the space of problem solvers. Their relatively greater ability is more than offset by their lack of problem-solving diversity."

Why is a nation that considers spending a civic duty approving harsher ways to punish the bankrupt?

Walter Kirn in the New York Times Magazine:

...thanks to an almost certain new federal law that the president has vowed to sign, this ending is set to grow unhappier still -- at least for a significant percentage of the one million to one and a half million Americans who file for bankruptcy protection every year and will, as early as this autumn, find it much harder to wipe clean their books and get back on their economic feet. For the credit-card issuers and consumer-finance companies whose well-financed lobbyists backed the bill (whose central provision requires bankrupt debtors with incomes exceeding their statewide median incomes to settle for long-term repayment plans), the results should prove more gratifying.

For a nation whose very founding can be viewed as an attempt to free itself from financial burdens thrust upon it by a distant ruler; for a government that is deeply in the red because of its own spendthrift ways; and for a political leadership whose emissaries have been pressuring other countries to forgive Iraqi debt, such a reform raises questions, to put it mildly.

Was Billie Holiday a victim of drink and drugs or...

Julia Blackburn's biography of The First Lady of Jazz reviewed in The Guardian:

'She could crack your skull with a riff'... Billie Holiday plays New York in 1942

In November 1956, Holiday was interviewed by Tex McCreary. She sounds heavy with alcohol and whatever drugs she might have been using, and the conversation is slow and awkward. The interviewer obviously feels it's no good going on with the questions and she was in no fit state to sing, but he has a sudden inspiration. He asks her to recite one of her songs. "I want you to close your eyes, Billie," he says, "and speak the words like a poet. What about 'Yesterdays'?"

Without a moment's hesitation she does what she has been told to do. She recites the words with an almost unbearable languor, but with all the power and authority of a great theatrical monologue. Her voice sounds like a song, so musical in its resonances that as you listen you seem to hear a band playing with her:

Yesterdays,

Days I knew as happy sweet,

Sequestered days,

Olden days, golden days,

Days of mad romance and love.

Then gay youth was mine,

Truth was mine,

Joyous free and flaming life,

Forsooth were mine.

Sad am I, glad am I,

For today I'm dreaming of,

Yesterdays...

So that is the sort of performance she might have given if she could appear before us now, and you cannot doubt that everyone listening to her would hold their breath in awe and delight.

Doctors and Dollars

Atul Gawande asks how much doctors should be paid, in The New Yorker:

For those who have Medicare—its payments are near the middle of the range—an office visit for a new patient with a “low complexity” problem (service No. 99203) pays $77.29. A visit for a “high complexity” problem (service No. 99205) pays $151.92. Setting a dislocated shoulder (service No. 23650) pays $275.70. Removing a bunion: $492.35. Removing an appendix: $621.31. Removing a lung: $1,662.34. The best-paid service on the list? Surgical reconstruction for a baby born without a diaphragm: $5,366.98. The lowest-paying? Trimming a patient’s nails (“any number”): $10.15. The hospital collects separately for any costs it incurs.

The notion of a schedule like this, with services and fees laid out à la carte like a menu from Chili’s, may seem odd. In fact, it’s rooted in ancient history. Doctors have been paid on a piecework basis since at least the Code of Hammurabi; in Babylon during the eighteenth century B.C., a surgeon got ten shekels for any lifesaving operation he performed (only two shekels if the patient was a slave). The standardized fee schedule, though, is a thoroughly modern development.

US supply of biological materials to Iraq

David Smith at Preoccupations brings attention to Geoff Holland's important (but largely ignored by the media) work:

Geoff Holland emailed me yesterday:

In case this is of interest, here is an article just published by Irene Gendzier, Professor of History and Politics at the University of Boston, who specialises in the Middle East. This prelude to her latest book mentions our campaign in Britain to hold the US accountable for supplying Iraq with the materials which fuelled its biological weapons programme.

There are now 122 MP signatures on the current House of Commons Early Day Motion 'Biological and Toxin Weapons Convention and Iraq' (EDM 303), tabled by Austin Mitchell MP. In the Scottish Parliament, where the same Motion has been tabled (S2M-2050) by Chris Ballance, 19 MSPs have now signed.

Many thanks to all who have supported the campaign by asking their MP or MSP to sign and in many other encouraging ways. If we have achieved nothing else, at least a few more people have given thought to this vitally important matter. For example, there have been more than 31,000 hits on the campaign website and there are now numerous links to this site on other websites.

The Color of Palo Alto

Samuel Yates's art project:

The artist will begin his search for “The Color of Palo Alto” by photographing every parcel of land in Palo Alto with a digital camera, five days per week, Monday thru Friday. He will alternate between 68 and 69 photos per day. The photographs will be taken alphabetically from the "A" streets through the "Z" streets from January 3 to December 30, 2005.

Together with artist Eli Schleifer, who wrote a software program for the project that finds the average pixel color of each digital photograph, Yates will find the average color of each neighborhood, street, and parcel in Palo Alto.

In a democratic manner, each parcel in the city will contribute one “vote” of color toward the final color of Palo Alto.

The average color of all 17,860 photographs will then become a paint color, to be referred to as “The Color of Palo Alto.” There will also be average colors for each neighborhood, street, and parcel in the city.

B.F. Skinner, Revisited

David P. Barash in the Chronicle of Higher Education:

I am not now, nor have I ever been, a devotee of behaviorism, radical or otherwise. Moreover, when I teach or write about animal behavior, I often counterpoise B.F. Skinner's work in particular as the intellectual antipode of my own perspective, which emphasizes the importance of built-in, prewired, evolutionarily generated mechanisms. For Skinner and his disciples, living things (including human beings) are tabula rasa, blank slates upon which the contingencies of reinforcement write as they will, thereby constituting the crucial -- indeed, the only -- determinant of behavior: the experience of each individual...

Into my own comfortable conceptual dichotomy ("behaviorism bad; evolutionism good"), there came an apple of discord when I happened to reread Skinner's Beyond Freedom and Dignity, published more than three decades ago.

Please don't misunderstand: I haven't become a convert to behaviorism. But I have emerged with a deeper respect for B.F. Skinner and his work, and a recognition that in his legacy, not just evolutionary biologists but all scientists have a potent intellectual ally. His research didn't encompass neurobiology, sociobiology, or, indeed, biology at all. But there is no doubt that he "did" science, and moreover, that he provided the rest of us with some conceptual tools and arguments that will help us along our way.

Award for novel of love and racism

John Ezard writes in The Guardian:

Maps for Lost Lovers, which took Nadeem Aslam 11 years to write, was declared in San Francisco as joint winner of the annual Kiriyama award, which aims to raise understanding of the peoples of the Pacific rim and south Asian diaspora.

The novel is a combined love story and murder mystery set in a poor south Asian enclave where a local curse is "May your son marry a white woman". It centres on Kaukab, a pious Muslim woman who relies on her faith to ease her feelings of estrangement from her homeland of Pakistan and from her husband and westernised children.

It dramatises both white and Asian racism and deals with arranged marriages and Muslim divorce. Aslam, 39, who won literary awards for his first novel Season of the Rainbirds, is the son of Pakistani parents who settled in Huddersfield in the 1980s.

Early Risers Have Mutated Gene

John Roach reports in National Geographic News:

"I'm wide awake and ready to paint the house," the 49-year-old Colchester, Vermont, resident said. "I don't need a cup of coffee to get going, not at all. But between 4:00 and 5:00 [p.m.] you might have to nudge me with an elbow." Middlebrook suffers from what is known as familial advanced sleep phase syndrome, or FASPS. Her body's clock is out of sync with the sleep-wake rhythm most of the world lives by. She goes to bed each night between 5:30 and 7:30 p.m. and wakes in the wee hours of the morning.

"The net result is you can feel very isolated," Middlebrook said. "Who wants to party at three in the morning? Nobody I know, and I'm not headed to the local bar to see who's still there." Instead, she quietly cleans the house, makes breakfast, or cuddles up with a book.

About three-tenths of a percent of the world's population lives like this, including two of Middlebrook's sisters, her daughter, and her mother. "Their whole clock is shifted," said Ying-Hui Fu, a neuroscientist at the University of California, San Francisco. Fu and colleagues report in tomorrow's issue of the science journal Nature on a newly discovered mutation to a single gene that they say causes FASPS. In addition to FASPS, four of the five individuals showed signs of depression, Fu said. "[The depression] is most likely caused by the same thing," she said. "As we probe deeper into how this mutation causes sleep problems, it very likely will also give insight to how the mutation will cause depression."

MicroRNA Is a Big Topic in Bio

Kristen Philipkoski reports in Wired News:

One of the tiniest entities in the human genome is becoming a very big deal in biology, with implications for the treatment of cancer, diabetes and brain disorders. MicroRNA, or miRNA, was considered relatively unimportant less than a decade ago. The tiny bits of RNA play a part in gene regulation, which involves how and when genes turn on and off. When the human genome proved to have fewer than 25,000 genes instead of the 100,000 or so that many scientists predicted, gene regulation became the focus of much attention. Suddenly it wasn't the genes themselves that held the most intrigue, but the things that influence their behavior and the proteins that the gene-regulation process produces.

MiRNA seems to stifle the production of proteins exclusively -- a function opposite that of its better-known relative, messenger RNA, or mRNA, which translates instructions from genes to create proteins. Researchers estimate there could be anywhere from 200 to 1,000 miRNAs -- the range is wide because miRNAs are so small, making them difficult to detect. Gary Ruvkun, a Harvard University researcher and pioneer of miRNA research, has called the tiny entities "the biological equivalent of dark matter, all around us but almost escaping detection." In a paper published in the Jan. 14 issue of Cell, David Bartel of the New York University School of Medicine predicted that miRNAs could regulate 30 percent of all human genes.

The Millennium Ecosystem Assessment

Duncan Graham-Rowe and Bob Holmes in New Scientist:

It has cost $24 million and taken more than 1300 scientists in 95 countries four years to put together. This week, the first ever global inventory of natural resources was finally published. Its overwhelming conclusion: we are living way beyond our means.

According to the Millennium Ecosystem Assessment (MA), approximately 60 per cent of the planet's "ecosystem services" - natural products and processes that support life, such as water purification - are being degraded or used unsustainably. What is more, this degradation increases the risk of abrupt and drastic changes, such as climate shifts and the collapse of fisheries.

But amid the doom and gloom there is hope. According to the MA, which is backed by the UN, the World Bank and the World Resources Institute, there is still tremendous scope for action that could mitigate these problems. "The future is in our hands," Robert Watson, MA project leader and chief scientist for the World Bank told New Scientist.

The Big Book of Jewish Conspiracies

Izzy Grinspan in The Village Voice:

One of the toughest things about being a Jew in today's America is that everyone assumes you are innately hilarious. It's not the worst stereotype—better to be the comedians than the ones with the noses. Sometimes, though, it makes otherwise clever writers get lazy.

David Deutsch and Joshua Newman's The Big Book of Jewish Conspiracies is a funny joke in the form of a sloppy book. Jews, according to the book's premise, are behind most of the major events in history, especially the catastrophic ones. The bubonic plague? Naturally. Feminism? Of course. September 11? You get the idea.

Reviewing Reviewers

Sarah Boxer in the New York Times:

Do you remember Charles and Ray Eames's 1977 film "Powers of Ten," in which the camera zooms back from the surface of the Earth to a far-off point in space? As the details of the planet recede and vanish, new features of the universe appear. Before you know it, you've been sucked into another order entirely.

Sometimes the Internet is like that. The traditional objects of culture - books, movies, art - are becoming ever more distant. In their place are reviews of reviews, museums of museums and many, many lists.

Ron Hogan, who writes a literary blog called Beatrice.com, recently began a second blog, Beatrix: A Book Review Review. He's not the only one reviewing reviewers. The blogs Bookdwarf, Conversational Reading, The Elegant Variation, Golden Rule Jones, The Reading Experience and Confessions of an Idiosyncratic Mind - all gloss, grade or review other people's book reviews.

Lovecraft: Too Legit to Quit

It's official: H.P. Lovecraft isn't just some creepy schoolboy's secret literary fare anymore, but a bona fide Amercian Author. At least that's how I read the Library of America's recent publication of Lovecraft's Tales, edited by Peter Straub. Why all the sudden interest in Lovecraft? The Believer recently published French enfant terrible Michel Houellebecq's essay on Lovecraft and intends to publish Lovecraft: Against the World, Against Life at some point soon. (Lovecraft is to Houellebecq what Poe was to Baudelaire; I'm not sure what it is about ornate American works of terror that so rivets the French imagination, but hey.) Nick Mamatas of the Fortean Bureau has already pointed out that Lovecraft entered "the Canon" (if you're worried about such things) when Penguin published his work. Meanwhile, Laura Miller finds both Lovecraft and his admirers a little loathsome in her firm but pretty fair Salon review. Miller rightly dwells on Lovecraft's pathological racism (see, e.g., Lovecraft's "Rats in the Walls"), but that never slowed down the Canonization of Chandler or Jack London either. More provocatively, Miller asks Why Lovecraft? when Edmund Wilson doesn't have a Library of America volume yet.

The answer, I think, has something to do with Lovecraft's strange enduring influence, his weird mythology the nightmare American version of J.R.R. Tolkien's steadily increasing stock, which is something other than strictly literary. I have one Lovecraft theory, rather political in nature, which I wouldn't go out on a limb to defend. When a continent is conquered by war, slavery, and racial extermination, the landscape, only seeming to lack a persistent cultural memory, could come back to haunt us, with monsters bred out of the sleep of reason. In this sense, I see Lovecraft in a line with William Burroughs, whose conclusion from a superficial and exoticized look at the native culture of Central and South America, in addition to the white madness that displaced it and the native peoples of North America, was that America was simply an evil land. It is surely right to place Lovecraft's externalized demons back into his head, biographically speaking, but there's something odd and inexplicable about his cultural persistence. What it boils down to, perhaps, is not only that America is haunted, an "old world" also (at last, the truth admitted), but also that in Lovecraft we see the ultimate denial and dramatic reversal of the original American Dream of Starting Over in an Edenic land of boundless possibility and natural beauty.

Financing democratic change in Kyrgyzstan

Following on Alex Cooley's editorial, here's a report on how the West's support for opposition newspapers helped in the downfall of Akayev.

"Shortly before Kyrgyzstan's recent parliamentary elections, an opposition newspaper ran photographs of a palatial home under construction for the country's deeply unpopular president, Askar Akayev, helping set off widespread outrage and a popular revolt in this poor Central Asian country.

The newspaper was the recipient of United States government grants and was printed on an American government-financed printing press operated by Freedom House, an American organization that describes itself as 'a clear voice for democracy and freedom around the world.'

In addition to the United States, several European countries - Britain, the Netherlands and Norway among them - have helped underwrite programs to develop democracy and civil society in this country. The effort played a crucial role in preparing the ground for the popular uprising that swept opposition politicians to power."

On the Collapse of the Kyrgyz Kleptocracy

Alex Cooley writes on events in Kyrgyzstan.

"The revolution in Kyrgyzstan not only represents a new opportunity for the Kyrgyz people, but also for Western governments that have failed to support true democratization in post-Soviet Central Asia.

The West must abandon its support for regional strongmen who merely profess to be Western-oriented, and should set the same expectations of democratic governance for them as it has for other post-Communist states.

In fact, the United States and European governments share some responsibility for the Kyrgyz regime's years of incompetent and corrupt rule. Immediately after the dissolution of the Soviet Union, Kyrgyzstan stood out as the only Central Asian country that appeared willing to break from its Communist past.

Its new president, Askar Akayev, was a charismatic former scientist who promised to enact Western-style democratization and pursue economic liberalization, hailing his small country as the 'Switzerland of Central Asia.'"

The Company of Strangers: A Natural History of Economic Life

  Economist Paul Seabright is fascinated by human cooperation. Mistrust and violence are in our genes, he says, but abstract, symbolic thought permits us to accept one another as "honorary relatives"—a remarkable arrangement that ultimately underlies every aspect of modern civilization.

In developing these ideas for his latest book—The Company of Strangers: A Natural History of Economic Life—Seabright traveled widely, especially in Eastern Europe and Asia. He currently lives in southwest France, where he teaches economics at the University of Toulouse.

American Scientist Online managing editor Greg Ross interviewed Seabright by e-mail in March 2005.

You point out that human society has led us to interact as strangers only in the last 10,000 years, while we still carry deeper instincts toward violence and suspicion of outsiders. How fragile is the social contract?

How full is the glass? It can seem extraordinary that the vast complexity of human cooperation—from road traffic patterns to markets, the Internet and the systems that keep our houses and cities safe—should rest on nothing more solid than social convention, as though civilization were founded purely on table manners. I may think my property is secure and my life reasonably protected, but that is only because the rest of the world has agreed, for the time being, to let them be so. And what people have agreed to respect today they can agree to violate tomorrow. Yet it is just as remarkable how robust many of our conventions turn out to be in practice. Partly this is because conventions govern our reactions to people as roles and not just as individuals—an assassinated president can be replaced by a vice president, and the system as a whole can go on functioning, with people listening to the new president much as they would have listened to the old. Partly it is because the hydra of social life has too many heads to be easily incapacitated: The conventions that sustain our physical security are not coordinated in one place, such as the U.N. or the Pentagon, but are the result of billions of individual decisions concerning how we react to neighbours, friends and colleagues. Some circumstances—the genocide in Rwanda, for instance—upset those conventions radically, so that neighbours, friends and colleagues become each others' greatest threat. But those circumstances are—fortunately—rare, and the capacity of societies to recover from them has historically proved remarkable.

Hair is good source of stem cells

  The fact that hair grows quickly and is continually replenished makes it an attractive source to harvest the amount of stem cells needed for treatments. This has been a major stumbling block of stem cell research, as well as controversy surrounding the ethics of harvesting cells from embryos. The Proceedings of the National Academy of Science study shows nerve cells can be grown from hair follicle stem cells. Read more here as reported by BBC. (Image: COURTESY OF THE PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES).

Inside a hair follicle is a small bulge that houses stem cells. As hair follicles cycle through growth and rest periods, these stem cells periodically differentiate into new follicle cells. Yasuyuki Amoh of AntiCancer, Inc. and his colleagues isolated stem cells from the whiskers of mice and tested their ability to become more sophisticated cell types. The researchers cultured the cells and after one week discovered that they had changed into neurons and two other cell types--known as astrocytes and oligodendrocytes--that are associated with neurons. According to the report, when left for longer periods lasting weeks or months, the stem cells could differentiate into a variety of cell types, including skin and muscle cells.

Asteroid Impact Fueled Global Rain of spherules

Michael Schirber in Space.com:

The asteroid that struck the Yucatan Peninsula 65 million years ago presumably initiated the extinction of the dinosaurs. The huge collision also unleashed a worldwide downpour of tiny BB-sized mineral droplets, called spherules.

The hard rain did not pelt the dinosaurs to death.

But the planet-covering residue left behind may tell us something about the direction of the incoming asteroid, as well as possible extinction scenarios, according to new research. The falling spherules might have heated the atmosphere enough to start a global fire, as one example.

The evolutionary revolutionary

Drake Bennett writes in The Boston Globe about Robert Trivers:

Trivers's ideas have rippled out into anthropology, psychology, sociology, medicine, even economics. His work provided the intellectual basis for the then-emergent field of sociobiology (now better known as evolutionary psychology), which sought to challenge our conceptions of family, sex, friendship, and ethics by arguing (controversially) that everything from rape to religion is bred in the bone through the process of evolution. The linguist and Harvard psychology professor Steven Pinker calls Trivers ''one of the great thinkers in the history of Western thought.'' Now his decades-long absence-what Trivers's friends and colleagues refer to as his ''fallow period''-finally seems to be ending. In 1994 he left Santa Cruz (''the worst place in the country,'' he now calls it) for Rutgers, and this spring he's back at Harvard as a visiting professor of psychology. A major new book on genetic conflicts within individual organisms, coauthored with Austin Burt, a geneticist at Imperial College London, is due out next spring from Harvard University Press. And thanks to Brockman-agent to some of the biggest names in science-he's under contract with Viking Penguin to write a popular book on the evolutionary origins of deceit and self-deception, one that will argue that humans have evolved, in essence, to misunderstand the world around them. Trivers thinks it could be the most important topic he has yet studied.

Trivers's work grew out of an insight made by the Oxford biologist William D. Hamilton, who died in 2000. In a 1964 paper, Hamilton proposed an elegant solution to a problem that had rankled evolutionary theorists for some time. In a battle of the fittest, why did organisms occasionally do things that benefited others at a cost to themselves? The answer, Hamilton wrote, emerged when one took evolution down to the level of the gene. Individuals were merely vessels for genes, which survived from generation to generation, and it made no difference to the gene which organism it survived in. According to this logic, the degree to which an organism was likely to sacrifice for another should vary in direct proportion to the degree of relatedness: Humans, for example, would be more likely to share food with a son than a second cousin, and more likely to share with a second cousin than someone wholly unrelated. Hamilton called the concept ''inclusive fitness.''

In 1976, the Oxford zoologist Richard Dawkins would popularize Hamilton's ideas in his book ''The Selfish Gene.'' But more than anyone else, it was Trivers, then a graduate student, who grasped the profound implications of Hamilton's work. In a way, Trivers's legendary papers of the early 1970s were simply a series of startling applications of its logic.

Bacteria act as glue in nanomachines

Electrodes snare microbes in key sites on silicon wafers.

Prachi Patel Predd writes in Nature: Electric currents are being used to move bacteria around silicon chips and trap them at specific locations. The technique could help to assemble nanomachines from miniature parts, and to create a new generation of biological sensors. Nanodevices are typically built by connecting tiny components. But such a delicate task is not easy. So, many researchers are exploring ways to fix components in place using the binding properties of biological molecules, notably DNA. Robert Hamers and his colleagues from University of Wisconsin-Madison propose using entire microbes instead. The cells have surface proteins that attach to certain biological molecules. Once the cells are placed at specific sites on a silicon wafer, nanoparticles tagged with these molecules can bind to the cells in those locations. This is easier than dragging the nanoparticles themselves to the right spot, because their high density makes them harder to move through fluid media than the less dense living cells. The technique gives one a way to fix components such as quantum dots or carbon nanowires at very precise locations, explains Paul Cremer, a bioanalytical chemist at Texas A&M University in College Station. "That's potentially very exciting," he says.

Golden rods: The researchers use Bacillus mycoides, rod-shaped bacteria that are about 5 micrometres long. They pass a solution containing the cells over a silicon wafer with gold electrodes on its surface. The charge on the electrodes captures the bacteria, which flow along the electrodes' edges like luggage on a conveyor belt. The electrodes have tiny gaps between them. When a bacterium reaches a gap, it is trapped there by the electric field. It can be released by reducing the field between the electrodes, or permanently immobilized by increasing the voltage enough to break its cell wall.

Evo Devo Is the New Buzzword ...

Brian K. Hall writes in the Scientific American:

The study of embryonic stages across the animal kingdom--comparative embryology--flourished from 1830 on. Consequently, when On the Origin of Species appeared in 1859, Charles Darwin knew that the embryos of all invertebrates (worms, sea urchins, lobsters) and vertebrates (fish, serpents, birds, mammals) share embryonic stages so similar (which is to say, so conserved throughout evolution) that the same names can be given to equivalent stages in different organisms. Darwin also knew that early embryonic development is based on similar layers of cells and similar patterns of cell movement that generate the forms of embryos and of their organ systems. He embraced this community of embryonic development. Indeed, it could be argued that evo devo (then known as evolutionary embryology) was born when Darwin concluded that the study of embryos would provide the best evidence for evolution.

Darwin's perception was given a theoretical basis and evo devo its first theory when Ernst Haeckel proposed that because ontogeny (development) recapitulates phylogeny (evolutionary history), evolution could be studied in embryos. Technological advances in histological sectioning and staining made simultaneously in the 1860s and 1870s enabled biologists to compare the embryos of different organisms. Though false in its strictest form, Haeckel's theory lured most morphologists into abandoning the study of adult organisms in favor of embryos--literally to seek evolution in embryos. History does repeat itself; 100 years later a theory of how the body plan of a fruit fly is established, coupled with technological advances, ushered in the molecular phase of evo devo evaluated by Carroll.

Most mesmerizing music

I was fortunate enough to attend a most riveting, thrilling, gorgeous (even visually) musical performance last evening in Boston by the young and superbly talented group So Percussion, at the Isabella Stuart Gardner Museum and are performing there again this afternoon. Here's a bit more about them:

DAVID WEININGER in the Boston Phoenix:

A salute to Steve Reich at the Gardner         

It’s customary to file Reich under the minimalism tag, but the label is proving to be less and less useful these days. The steady pulse and gradually shifting rhythms are still there, but his best pieces are so complex, with so many compositional elements, that the label rings hollow. George Steel, Miller Theatre’s director and the host of the "Composer Portraits" series, agrees. "It’s a useful term, because people sort of know you mean Steve Reich or people following Steve," he says over the phone from his office. "But is there a minimal amount of material? No, they’re very rich pieces." Perhaps a better label would be Steve Reich, The Artist Formerly Known As a Minimalist.

Allan Kozinn in NY Times 3.25.05

As part of its Composer Portraits series, the Miller Theater is devoting an evening to Steve Reich, with two of his major scores performed by the inventive So Percussion ensemble. For So Percussion (above), the timing is perfect: the group just released a fantastic recording of one of these works, "Drumming," on the Canteloupe new-music label. "Drumming," composed in 1971, is a pivotal work in Mr. Reich's catalog, and it has been getting lots of performances lately (the most recent by Tactus, a student ensemble at the Manhattan School of Music, just a couple of weeks ago). It draws on the techniques that Mr. Reich had explored in his early "phase" pieces - works in which two lines that begin in unison move out of phase as beats are displaced, creating increasingly complicated webs of rhythm, timbre and psycho-acoustic effect. But it also looks back at his studies of African drum techniques. A performance can take on an almost ritualistic appearance; in fact, as the performers moved gradually from bongos to marimbas to xylophones and then to a combination of those instruments, plus voices and a piccolo, a listener can imagine an exotic hybrid of a gamelan orchestra and a factory production line. The other work on the program, Sextet, was composed in 1984, at a time when Mr. Reich was taking stock after the composition of "The Desert Music," a substantial piece for orchestra and chorus. Sextet, for four percussionists and two keyboard players (who double on pianos and synthesizers), begins with a figure from "The Desert Music" but then moves in its own direction.

R.M. Campbell in the Seattle Post Intelligencer:

The quartet, So Percussion, has been performing Reich's "Drumming" since its formation in 1999. Who better than these young, talented musicians to tackle the difficulties of Reich's famous score for percussion?

One of the most eloquent and inventive spokesmen in the world of minimalist music, the composer became intrigued with rhythm at an early age; his interest in Asian and African music came later. "Drumming," the devlopment of a single rhythmic figure inspired by Reich's experiences in Ghana, helped make him a celebrated figure and has been widely performed.

It would be hard to imagine a more persuasive performance then So Percussion's -- accurate, engaged and rich in vitality. Rarely does Western percussion sound so varied.

A new biography of Kierkegaard

John Updike in The New Yorker:

Joakim Garff, an associate professor at the Søren Kierkegaard Research Center at the University of Copenhagen, in a brief preface to his monumental “Søren Kierkegaard: A Biography” (translated from the Danish by Bruce H. Kirmmse; Princeton; $35), states that “the Danish biographies of Kierkegaard that have appeared since Georg Brandes’s critical portrait was published in 1877 can easily be counted on the fingers of one hand, and Johannes Hohlenberg’s biography from 1940 is the most recent original work in the field.” Garff’s compendious yet lively work is undeniably a Danish biography; it assumes on the part of its readers a prior acquaintance with, say, the poetry of Adam Oehlenschläger and the intellectuality of King Christian VIII, a firm sense of what the rix-dollar could buy in the eighteen-forties, and a Copenhagener’s inherent familiarity with the saga of his world-famous, locally notorious fellow-townsman Magister Søren Aabye Kierkegaard.

The Kierkegaardian tempest needed Copenhagen’s teapot.

Too Late to Die Young

Thomas Jones in the London Review of Books:

Catching news about the Michael Jackson trial, I can’t help being reminded of a caustic song by Dan Bern, a singer less famous than Jackson by several orders of magnitude, called ‘Too Late to Die Young’. ‘The day that Elvis died was like a mercy killing,’ it begins, before turning its attention to the inglorious late careers of other fallen idols of American popular culture, challenging listeners to ‘name the last good film that Marlon Brando made/While trying to keep his kid from going to jail.’ ‘Too late to crash, too late to burn, too late to die young,’ goes the chorus. The song is softened somewhat by the singer’s sense of his own life lacking much direction or purpose; and it’s more than aware that dying young isn’t on its own enough of an achievement to turn someone into James Dean.

‘Too Late to Die Young’ points up, too, the contradictions of being both a star and a human being, in terms not only of what consitutes the good – dying young v. living an ignominiously long life, for example – but also of the expectations of the crowd, who want their (our) heroes to be above common human frailties, but all the same can’t help probing for weaknesses, and are both sorely disappointed and gleefully reassured when we find them.

A small Oedipus still struggling with his father's shadow

Victor Sonkin in the Moscow Times:

Vladimir Nabokov's destiny was a difficult one. Forced into exile by the Revolution, he spent the early part of his life in Germany and France, working as a tutor and tennis coach while gradually becoming the greatest Russian writer of his time. Unfortunately, his poetry and fiction were appreciated only by a small emigre circle. After relocating to the United States, he continued to pursue his interest in entomology -- he had a lifelong passion for butterflies -- and, with the publication of "Lolita," he became a living classic of American literature. However, his early Russian novels, most of them translated into English by the author and his son Dmitry, have remained more obscure to U.S. readers than the books he wrote in English.

After the fall of the Soviet regime, Nabokov's books were finally published in Russia. Except for "Lolita," translated by the author into Russian -- although some critics consider this translation seriously inferior to the original -- his English-language novels have not achieved the same success here as "The Gift" or "Glory," his Russian masterpieces.

Imagination gets its due as a real-world thinking tool

Bruce Bower writes in Science News:

Marjorie Taylor of the University of Oregon in Eugene belongs to a contingent of researchers who regard imagination as a thinking tool. Kids regularly use their imaginations to figure out how the world works and to address mysterious issues, she notes, such as what God looks like and what happened in their families or in the world before they were born. Children also apply fantasy to sidestep pain. "Fantasy is alive and well in children's lives," Taylor says. According to Taylor, adults as well as children are imaginative thinkers—even while posing as staunch realists. From plumbers to prime ministers, individuals encounter and converse with others purely in their own thoughts, ponder the future, and rework past events in pleasing ways. "Imagination is about considering possibilities," Taylor says. "That's fundamental to how people think." 

A 3-year-old boy enthusiastically describes a scary creature after Harvard University psychologist Paul L. Harris shows the boy a box and asks him to imagine that a monster lives inside it. Nevertheless, the boy reassures Harris that a monster won't pop out if they open the box. The monster is only make-believe, the boy declares with an air of satisfaction. Harris then leaves the room for a few minutes. Alone with his thoughts, the youngster eyes the box nervously as he moves away from it.

This type of response, which kids regularly display by around age 2, doesn't mean that they fail to distinguish fantasy from reality, in Harris' view. Adults react in comparable ways, he says. In one experiment that he performed, adults filled a bottle with tap water and wrote the word cyanide on a label that they attached to the bottle. The volunteers knew that they were only pretending that the water was poisonous, but most wouldn't drink it. Taylor points out another example: Grown-ups get "really scared, not pretend scared," while watching horror movies.

In his book The Work of the Imagination (2000, Oxford), Harris proposed that people have evolved a brain system that goes to work appraising emotionally charged situations, whether or not they're real. In fact, responding emotionally to imagined scenarios aids decision making, he holds. For example, Harris has found a deficit among people who don't show physical signs of emotional involvement, such as an increased heart rate, while reading a suspenseful fictional passage. Such individuals score lower on tests of reasoning and logic than do people who show strong physical and emotional reactions to such tales.

From around the time that children begin to talk, Harris argues, they contemplate not only current and past events in the real world but also imaginary versions of the present and the past, future possibilities, and spiritual or supernatural concerns. He says that many other developmental psychologists neglect imagination's role in mental development. They assume that children generate reality-based theories primarily to explain what they observe around them, much as scientists do.

Cilia in C-Major

Elizabeth Gudrais in Harvard Magazine:

In the human ear, it takes only a few millionths of a second from the time a sound wave vibrates the receiving "hair cells" to the time the cells generate a neural response. The equivalent process in the human eye, from photon absorption to cellular response, takes a thousand times longer. Hearing "is fast because it's simple," says professor of neurobiology David P. Corey of Harvard Medical School.

Well, yes and no. On a basic level, it's easy to explain how we hear: sound waves, traveling through the air, vibrate the eardrum at certain frequencies and magnitudes, which the brain interprets to identify the sound's pitch and volume. Betwixt vibration and human perception, though, lie several intermediate steps. Hair cells in the inner ear convert sound waves -- a form of mechanical energy -- into electrical signals. In the brain, those messages make several transformations between electrical and chemical signals and back again, bouncing from neuron to neuron until they reach a final resting point where we perceive them as sound.

It was 30 years ago when Corey, as a graduate student at the California Institute of Technology, began applying his undergraduate background in physics -- and his childhood drive to take things apart and figure out how they work -- to the mystery of hearing. In a recent article in Nature, he and his colleagues describe a protein they believe adds a crucial piece to this intricate puzzle.

Scientists have long known that the eardrum vibrates and transmits the vibration to the inner-ear bones, touching off a mechanical process in the cochlea, the snail-shaped organ containing hair cells with bristly cilia that vibrate back and forth in response to sound waves -- the greater the cilia vibration, the louder the sound. (A video clip on this magazine's website, www.harvardmagazine.com/av/hearing.html, shows these cilia vibrating in response to a piece of music.)

Evangelist of the sanguinary and excremental

Barry Gewen in the New York Times:

ARTHUR C. DANTO is arguably the most consequential art critic since Clement Greenberg. He is an erudite and sophisticated observer, a trained academic philosopher who is also wholly at home in the world of modern art, about which he writes with forcefulness and jargon-free clarity. Yet what truly distinguishes Danto from his peers is that he offers his readers more than simply his personal (if highly informed) opinions. His responses to works of art, like Greenberg's, are grounded in a coherent intellectual structure that takes them out of the realm of free-floating subjectivity. To look at a work with Danto is to see it within the context of contemporary art, its very raison d'être.

In ''Unnatural Wonders,'' a collection of reviews written for The Nation between 2000 and 2004, framed by a few broadly philosophical essays, Danto declares: ''I was in a sense the first posthistorical critic of art. . . . What was special about me was that I was the only one whose writing was inflected by the belief that we were not just in a new era of art, but in a new kind of era.'' Greenberg was set on his critical path by Jackson Pollock. Andy Warhol performed the same function for Danto, who argues that ever since Warhol's Brillo boxes of 1964, an art object could be anything at all (or even nothing), that for the first time in history artists were free to do whatever they wanted -- to slice up dead animals, throw elephant dung on canvases, display their soiled underwear and used tampons, mold images of themselves out of their own blood. In this world of total freedom, the actual physical attributes of a work counted for less than its philosophical justifications. All art had become conceptual art, and the job of the critic was to articulate what meaning the particular artist wished to convey and how that meaning was embodied in the work at hand.

Evolution on Trial

Steve Kemper in Smithsonian Magazine:

In the summer of 1925, when William Jennings Bryan and Clarence Darrow clashed over the teaching of evolution in Dayton, Tennessee, the Scopes trial was depicted in newspapers across the country as a titanic struggle. Bryan, a three-time presidential candidate and the silver-tongued champion of creationism, described the clash of views as "a duel to the death." Darrow, the deceptively folksy lawyer who defended labor unions and fought racial injustice, warned that nothing less than civilization itself was on trial. The site of their showdown was so obscure the St. Louis Post-Dispatch had to inquire, "Why Dayton, of all places?"

It's still a good question. Influenced in no small part by the popular play and movie Inherit the Wind, most people think Dayton ended up in the spotlight because a 24-year-old science teacher named John Scopes was hauled into court there by Bible-thumping fanatics for telling his high-school students that humans and primates shared a common ancestry. In fact, the trial took place in Dayton because of a stunt. Tennessee had recently passed a law that made teaching evolution illegal. After the American Civil Liberties Union (ACLU) announced it would defend anyone who challenged the statute, it occurred to several Dayton businessmen that finding a volunteer to take up the offer might be a good way to put their moribund little town on the map.

The Future Will Be Peaceful, Inshallah

Rory Stewart looks at What We Owe Iraq: War and the Ethics of Nation Building by Noah Feldman, Blinded by the Sunlight: Surviving Abu Ghraib and Saddam’s Iraq by Matthew McAllester, The Fall of Baghdad by Jon Lee Anderson, and The Freedom: Shadows and Hallucinations in Occupied Iraq by Christian Parenti, in the London Review of Books:

Will the election make all the difference? For a year after the invasion the policy was to reduce the number of police in Maysan and make them more ‘citizen-friendly’. In the last six months the police force has tripled in size and is now heavily armed. People in Maysan seem to enjoy voting. But the province on election day looks a little like a police state. There are armed men at checkpoints every few kilometres up the highway; policemen with vehicle-mounted machine-guns are checking IDs on almost every street corner; no civilian vehicles are allowed to move on the streets. This may be part of the reason ‘security has improved.’ Yet despite the checkpoints, which are in place every day, there are still daily car-jackings and roadside bombs, and towards the Iranian border there’s drug smuggling, looting, and kidnapping of children. The improvement is relative. As the sheikh found when he was shot on the steps of his mosque.

No foreigner really knows what is going on in Iraq. There are diplomats – both British and American – who speak good Arabic and have studied Iraqi history; there are intelligence officers who know tribal genealogies; and there are many soldiers who get out on the ground, build good relationships with rural leaders, deliver services and win respect. The quality of journalists in Iraq has been high: Elizabeth Rubin for the New York Times Magazine and the New Republic, George Packer for the New Yorker, Rory McCarthy for the Guardian and James Astill for the Economist have produced great pieces. But even the most energetic analysts cannot move freely. Astill’s longest conversation with an Iraqi in Fallujah was with a man urinating against a wall with a suitcase on his head, and thus unable to move for twenty seconds.

I certainly don’t know what is going on in Iraq.

China's Building Blitz Without precedent in history

From the Architectural Record:

In scale and pace, the building boom currently sweeping over China has no precedent in human history. China is spending about $375 billion each year on construction, nearly 16 percent of its gross domestic product. In the process, it is using 54.7 percent of the world's production of concrete, 36.1 percent of the world's steel, and 30.1 percent of the world's coal.

Pomegranate Juice Fights Heart Disease

Stefan Lovgren reports for The National Geographic News:

In the mythology of ancient Babylonia, pomegranate was considered an agent of resurrection. Now there is scientific evidence for the fruit's restorative powers. According to a new study, antioxidants contained in pomegranate juice may help reduce the formation of fatty deposits on artery walls. Antioxidants are compounds that limit cell damage. Scientists have tested the juice in mice and found that it combats hardening of the arteries (atherogenesis) and related diseases, such as heart attacks and strokes.

"In this experimental study, we have established that polyphenols [antioxidant chemicals] and other natural compounds contained in the pomegranate juice may retard atherogenesis," said Claudio Napoli, a professor of medicine and clinical pathology at the University of Naples, Italy.

Pomegranate (Punica granatum) is native to a region ranging from Iran to the Himalaya. It later spread to the Mediterranean area and now grows in most of the United States. The apple-size fruit, which grows on rounded plants 15 to 20 feet (4.6 to 6 meters) tall, contains a sack of seeds and a juicy pulp. In ancient Greece pomegranate was known as the fruit of the dead. In Hebrew tradition pomegranates adorned the vestments of the high priest. Ancient Persians believed that pomegranate seeds made their warriors invincible. In China the fruit symbolized longevity.

The research is published this week in the Proceedings of the National Academy of Sciences. Read more here.

Scientists recover T. rex soft tissue: 70-million-year-old fossil yields preserved blood vessels

Reuters report:

70-million-year-old Tyrannosaurus rex fossil dug out of a hunk of sandstone has yielded soft tissue, including blood vessels and perhaps even whole cells, U.S. researchers reported on Thursday. To make sure she was seeing what she thought she was seeing, Schweitzer, a biologist by training, compared the Tyrannosaur samples with bone taken from a dead ostrich. She chose an ostrich because birds are thought to be the closest living relatives of dinosaurs and ostriches are big birds. Both the dinosaur and ostrich blood vessels contained small, reddish brown dots that could be the nuclei of the endothelial cells that line blood vessels.

What Adam Smith really said

Gavin Kennedy in The Scotsman:

Some on the Right brazenly saw in Smith’s name an authority against much of what he opposed on moral grounds. He was cited to oppose shorter working hours, to continue employing women and children in coal mines and dark satanic mills, even in defence of slavery. Smith allegedly advised against interference in the business of business.

The cries went up - Laissez faire! Leave the mine and mill owners alone! They know best. The invisible hand will come right in the end. It’s all in Smith’s Wealth of Nations. Interfere at your peril.

Some on the Left naively saw Smith as a compelling authority in favour of state intervention. Wilberforce quoted him against slavery, a practice Smith opposed on moral and economic grounds. Others quoted his support for the government to fund a school in every village so that each child would become literate and numerate. But they did not like his moral sentiments or his political economy.

The distortions of Smith’s views have conquered popular discourse. Libertarians on the Right vie with voices on the Left and sling quotations out of context - they long since gave up reading his books.

The distortions began shortly after Smith died in 1790.

Break, Blow, Burn

Clive James in the New York Times:

Clearly designed as a come-on for bright students who don't yet know very much about poetry, Camille Paglia's new book anthologizes 43 short works in verse from Shakespeare through to Joni Mitchell, with an essay about each. The essays do quite a lot of elementary explaining. Readers who think they already know something of the subject, however, would be rash if they gave her low marks just for spelling things out. Even they, if they were honest enough to admit it, might need help with the occasional Latin phrase, and they will find her analysis of individual poems quite taxing enough in its upper reaches. ''Having had his epiphany,'' she says of the sonnet ''Composed Upon Westminster Bridge,'' ''Wordsworth moves on, preserving his solitude and estrangement by shutting down his expanded perception.'' Nothing elementary about that.

She flies as high as you can go, in fact, without getting into the airless space of literary theory and cultural studies. Not that she has ever regarded those activities as elevated. She has always regarded them, with good reason, as examples of humanism's perverse gift for attacking itself, and for providing the academic world with a haven for tenured mediocrity. This book is the latest shot in her campaign to save culture from theory. It thus squares well with another of her aims, to rescue feminism from its unwise ideological allegiances. So in the first instance ''Break, Blow, Burn'' is about poetry, and in the second it is about Camille Paglia.

Internet Phone Service Creating Chatty Network

Ethan Todras-Whitehill in the New York Times:

JOHN PERRY BARLOW is pretty free and open, but he's no simpleton. So when he signed on to Skype, a free Internet phone service, and a woman identifying herself as Kitty messaged him, saying, "I need a friend," he was skeptical. He figured she was "looking for 'friends' to come watch her 'relax' in her Webcam-equipped 'bedroom.' "

Nevertheless, he took the call. "Will you talk to me?" she said. "I want to practice my English."

Kitty turned out to be Dzung Vu My, 22, a worker at an oil company in Hanoi, Vietnam. They spoke for a long time, exchanging text, photographs and Web addresses, and discussing everything from the state of Vietnam's economy to Ms. My's father's time in the army.

"One doesn't get random phone calls from Vietnam," Mr. Barlow, 57, the former Grateful Dead lyricist and co-founder of the Electronic Frontier Foundation, a nonprofit advocacy organization for an unfettered Internet, wrote on his blog. "At least, one never could before."

Mr. Barlow's experience is not unique. Skype users report unsolicited contacts every day, and contrary to such experiences with phone and e-mail, the calls are often welcomed.

Skype was founded by Niklas Zennstrom and Janus Friis, the creators of Kazaa, a peer-to-peer file-sharing service.

Karachi's growing drug culture

Naveen Naqvi at NBC News:

At least 200 people, most in their twenties or thirties, partied away at a recent warehouse party and danced as a U.K.-based DJ played Danny Howells' album for Global Underground.

Many stood on high platforms, their hands and eyes raised to the DJ’s booth on a balcony. They wore glow-in-the-dark bracelets, sunglasses, designer sports wear, and canvas shoes.

The scene could have been in London or New York, but this "rave" took place in the industrial area of Karachi, where you could name your poison and have it within minutes. 

Dealers dressed in baseball caps, baggy jeans and loose t-shirts milled around selling ecstasy for as low as $11 and as high as $25 a tab, cocaine for about a $100 a gram, acid for $10 a hit, and fifty grams of hashish for about $15. 

The gathering, one of many in Pakistan's financial capital, demonstrated how the drug culture common to many Western capitals, has made inroads in one of the world's strictest Islamic states.

preposterous to characterize Columbia as anti-Semitic

Karen W. Arenson in the New York Times:

Faced with complaints that Columbia University has tolerated anti-Semitism and intimidation in its Middle East studies classes, Columbia's president said last night that academic freedom has some limits when it comes to the classroom and the broader educational experience.

"We should not elevate our autonomy as individual faculty members above every other value," the president, Lee C. Bollinger, said in a speech to the Association of the Bar of the City of New York.

Professors, he said, have a responsibility "to resist the allure of certitude, the temptation to use the podium as an ideological platform, to indoctrinate a captive audience, to play favorites with the like-minded and silence the others."

Arguing that the health and vigor of universities rests on their scholarly professionalism, Mr. Bollinger said that when there are lapses, they should not be "accepted without consequences."

His remarks came as Columbia awaits the report of an internal committee set up to investigate charges by some pro-Israeli students that they had been intimidated in classes by pro-Palestinian professors in the department of Middle Eastern and Asian languages and cultures and outside the classroom as well. They also said that this occurred for several years and that Columbia had not taken their charges seriously.

What exactly is a tangible interface?

The Feature interviews Matt Jones:

Matt Jones and Chris Heathcote are Nokia's oracles. Officially, Jones is a concept development manager and Heathcote is a user experience manager in Nokia's Insight & Foresight group. Unofficially, the two are inciting a revolution in the way we interact with our mobile devices, and each other. At last week's Emerging Technology Conference in San Diego, they wowed the crowd with a demonstration of a Nokia's Near Field Communication, a cell phone shell containing a reader for wireless electronic tags. According to the researchers, NFC isn't just another wireless standard though. Rather, it's a harbinger of the "tangible interfaces" to come.

TheFeature: What exactly is a tangible interface?

Jones: We're trying to come up with ways to rethink and remap the idioms of computing and communications that have traditionally been tied to the desktop and laptop so that they work better in the contexts in which people use smart phones. Embodied interaction through tangible interfaces is one way to do that.

TheFeature: Can you give a concrete example?

Jones: We're looking at how touch can be used to execute a number of tasks or interactions so you don't have to switch contexts from the real world to the world inside the screen. For instance, one person could touch his device to someone else's and give them a "digital gift," to borrow a phrase from our old boss Marko Ahtisaari. That digital gift might be something as simple as a URL or a photo that I've taken of a moment we just shared.

TheFeature: Awww. That's sweet.

Jones: Well, I don't want to get too Hallmark about it. All joking aside though, the touch technology provides measurable quantitative differences in the efficiency by which people can complete that kind of task. In terms of the measurements that people wearing white coats take inside usability labs, touch technology could reduce the number of interactions required by an order of magnitude.

Evolution at Work (and creationism nowhere in sight)

Carl Zimmer in his blog, The Loom:

You may have heard last month's news about an aggressive form of HIV that had public health officials in New York scared out of their professional gourds. They isolated the virus from a single man, and reported that it was resistant to anti-HIV drugs and drove its victim into full-blown AIDS in a manner of months, rather than the normal period of a few years. Skeptics wondered whether all the hoopla was necessary or useful. The virus might not turn out to be all that unusual, some said; perhaps the man's immune system had some peculiar twist that gave the course of his disease such a devastating arc. But everyone did agree that the final judgment would have to wait until the scientists started publishing their research.

Today the first data came out in the Lancet. One of the figures jumped out at me, and I've reproduced it here. The scientists drew the evolutionary tree of this new strain. Its branch is marked here as "index case." The researchers compared the sequence of one its genes to sequences from other HIV strains, looking to see how closely related it was to them. The length of the branches shows how different the genetic sequences are from one another. The tree shows that this is not a case of contamination from some other well-known strain. Instead, this new strain sticks way out on its own.

The memoir mountain

William Grimes in the New York Times:

In 1884, Ulysses S. Grant, desperate for money and terminally ill with cancer, did what countless statesmen and military leaders had done before him: he sat down to write his memoirs. Racing against the clock, he turned out two substantial volumes on his early life and his military experiences in the Mexican and Civil Wars.

By any measure, he had a lot to write about and a lot to tell. He produced a classic memoir, as the genre was then understood: important events related by a great man who shaped them.

But that was then.

Today, Grant's memoirs fall into the same sprawling category as "Callgirl: Confessions of an Ivy League Lady of Pleasure," "Bat Boy: My True Life Adventures Coming of Age With the New York Yankees" and "Rolling Away: My Agony With Ecstasy," to pluck just three titles from the memoir mountain looming in the next month or two.

A New Company to Focus on Artificial Intelligence

John Markoff in the New York Times:

The technologist and the marketing executive who co-founded Palm Computing in 1992 are starting a new company that plans to license software technologies based on a novel theory of how the mind works.

Jeff Hawkins and Donna Dubinsky will remain involved with what is now called PalmOne, but on Thursday they plan to announce the creation of Numenta, a technology development firm that will conduct research in an effort to extend Mr. Hawkins's theories. Those ideas were initially sketched out last year in his book "On Intelligence: How a New Understanding of the Brain Will Lead to the Creation of Truly Intelligent Machines," co-written with Sandra Blakeslee, who also writes for The New York Times.

Dileep George, a Stanford University graduate student who has worked with Mr. Hawkins in translating his theory into software, is joining the firm as a co-founder.

Radical report supports baby sex selection

Shaoni Bhattacharya in New Scientist:

Parents undergoing fertility treatment should be allowed to choose the sex of their baby for "family balancing", says a radical report by the UK parliament's committee on science and technology.

The controversial document makes many other bold suggestions on human reproductive technologies. It does not rule out human reproductive cloning in the future; it backs the use of human-animal hybrid embryos for research; and it challenges the UK government's intention to strip the anonymity from future sperm and egg donors.

Revolutionary Science

Jed Z. Buchwald reviews Science and Polity in France: The Revolutionary and Napoleonic Years by Charles Coulston Gillispie, in American Scientist:

The book's nine chapters range from a careful account of the involvement of scientists in the early revolutionary Constituent Assembly, through discussions of education, the profoundly important creation of the Muséum d'Histoire Naturelle, the development of the metric system, and the years of the Terror, war and reaction. Along the way we meet some astonishingly colorful and often tragic characters. There are, for instance, the unfortunate Jean-Sylvain Bailly, a mediocre astronomer who became Mayor of Paris and met his end during the Terror, and the great chemist Lavoisier, a member of the General Tax Farm, who never could do things halfway and who thought that rational deliberation would always trump emotion. He too felt the kiss of Madame Guillotine, and none of his politically well-placed confreres (including the mathematician Gaspard Monge and the chemist Claude-Louis Berthollet) "said a word or lifted a finger." We meet as well the young Laplace, onetime collaborator of Lavoisier and eventually a central figure in French mathematics and physics, as well as a sometime administrator, of whom Napoleon remarked that "he brought the spirit of infinitesimals to administration."

Wrestling With a 'Lolita' Opera and Losing

Daniel J. Wakin in the New York Times:

In an introduction to the score for his "Darkbloom: Overture for an Imagined Opera," which will have its premiere with the Boston Symphony Orchestra tonight, John Harbison calls the piece the remnant of a misguided project, an "unproduceable" opera based on a "famous and infamous" American novel.

What made it unproduceable, at least in part, was the Roman Catholic Church's sexual abuse scandal involving priests and minors, Mr. Harbison said in an interview this week. The novel was Vladimir Nabokov's "Lolita," a work about a man's passion for an adolescent girl.

"I suppose the subject matter never has been more socially unacceptable than it is now in the United States," Mr. Harbison said. "Obviously I began to think more about that."

Bobby Fischer’s scabrous and hate-filled farewell

Richard Lloyd Parry in The Times:

After nine months of captivity and bitter legal struggle the former world chess champion flew to freedom in Iceland, spraying his vitriol far and wide. Japanese politicians, he declared, were “gangsters”. The US was “Jew-controlled”. “This was not an arrest,” he said, in the few minutes that he was audible to reporters between his arrival at Narita airport in Tokyo and his departure for Reykjavik. “It was a kidnapping cooked up by Bush and (the Japanese Prime Minister Junichiro) Koizumi. They are war criminals and should be hanged.”

To underline his point, he unzipped his trousers as he approached the airport, and made as if to urinate on the wall. This is the man who on the night of September 11, 2001, applauded the attacks on the United States as “wonderful news”, expressing the hope that Americans as a consequence “will imprison the Jews, they will execute several hundred thousand of them at least”.

Man smuggles own art into MoMA

From CNN:

Many a visitor to New York's Museum of Modern Art has probably thought, "I could do that."

A British graffiti artist who goes by the name "Banksy" went one step further, by smuggling in his own picture of a soup can and hanging it on a wall, where it stayed for more than three days earlier this month before anybody noticed.

The prank was part of a coordinated plan to infiltrate four of New York's top museums on a single day.

Rousseau's Narcisse at The Theater for the New City

Via Crooked Timber, Narcisse, a play by Jean-Jacques Rousseau, will be performed for the first time in the U.S. at the Theater for the New City, April 7th through April 10th.

Eyeball Planet and The Theater for the New City are delighted to announce the American premiere of Jean Jacques Rousseau’s play NARCISSE; a masterpiece which the legendary philosopher wrote at the age of 18 years old. NARCISSE has never been performed in the United States and will make its contemporary debut in a stunning, surrealistic and experimental production.

. . .

NARCISSE is an utterly contemporary drama that deals with the problem of narcissism and sexual ambiguity. The play is about a man who falls in love with an image of himself dressed as a woman and explores contemporary issues of desire, self-obsession and the difficulty of the relation between the sexes.
