From MSNBC:

Scientists have forced a little evolution in the laboratory, controlling whether a caterpillar becomes green or black. The color of the critter was made to vary with temperature during their development. The experiment reveals the basic hormonal mechanism underlying the evolution of such dual traits, the researchers report in Monday’s issue of the journal Science. The study was done on Manduca sexta, a caterpillar commonly called the tobacco hornworm. Its larvae are normally green. A related species, Manduca quinquemaculata, becomes black or green depending on temperature. The idea was to use similar temperature shocks to evolve a similar change in M. sexta.

Similar differences show up in genetically identical ants, which can develop into queens, soldiers or workers, based on the hormones they’re exposed to early in development. Similar hormonal differences can affect the specific color of a butterfly or bird.

The language of peace-making is everywhere, though. Sometimes it is curiously belligerent. ANGELIC PEACE LOCOMOTIVE CRUSHES LIFE OUT OF WAR DEVIL MONGERS was the headline in one Khartoum newspaper reporting the agreement. The less peace there is, the more people want to hear the magic word. A South Sudanese hip-hop artist, Emmanuel Jal, and a veteran northern Sudanese musician, Abdel Gadir Salim, recently recorded an album called Ceasefire. The two singers have never met: their album was made by sending recorded tracks back and forth between London, Khartoum and Nairobi, in Kenya, where Jal has been living. The result of this collaboration-at-a-distance is a wondrous fusion of the 6/8 merdoum rhythm of western Sudan with rap techniques honed in the dance halls of Nairobi. The songs are in a mix of English, Arabic, Nuer (Jal’s native language) and Sheng, a street language that is Kenya’s equivalent of the Spanglish spoken by Latinos in North America. In July, Jal performed in Cornwall at one of Bob Geldof’s Live 8 concerts. In August, he sang at the memorial event in London for John Garang, leader of the SPLM, who was killed in a helicopter accident shortly after the formation of the new government in Khartoum.

Landlines (2005), the first thing you see upon entering the exhibition of paintings by Langdon Quin on display at Kraushaar Galleries Inc., is so strange and good—so aloof yet oddly gripping—that it’s too bad the gallery felt it necessary to display other examples of the artist’s recent work. Not that there’s anything terribly wrong with the rest of Mr. Quin’s pictures. There are additional landscapes depicting Umbria, the subject of Landlines, as well as a handful of still-life and figurative pictures. A traditionalist through and through, Mr. Quin brings a sober sense of measure to everything he touches. There’s not a spot on the canvases that hasn’t been given his full and steady attention.

From The Boston Globe:

WHEN THE philosopher Daniel Dennett was a teenager, he played the backwoods holy man Elijah in his prep school’s production of ”Inherit the Wind.” ”Bearded, wild-haired, dressed in a tattered burlap smock,” Elijah comes down from the hills, on the eve of Bert Cates’s trial for teaching evolution, to sell Bibles out of an old vegetable crate. ”Are you an evolutionist? An infidel? A sinner?” Elijah asks an out-of-town newspaperman.

Until he went to graduate school, Dennett claims, the play, famously based on the 1925 Scopes ”monkey trial,” was the source of most of what he knew about evolution and natural selection. Today Dennett has a prophet’s beard, one corner of which he will sometimes fold into his mouth for a ruminative chew, and he is one of Darwinian theory’s foremost promoters. He sees it not just as an explanation for the origin of species, but for the fundamental whys and hows of human habits, beliefs, thinking, and desires. The logic of evolution, Dennett wrote in his 1995 book ”Darwin’s Dangerous Idea,” is a ”universal acid,” it ”eats through just about every traditional concept, and leaves in its wake a revolutionized worldview.”

Religion, Dennett says, is human behavior, and there are branches of science to study human behavior. ”Whether or not [Gould] was right,” Dennett told me in his office at Tufts University, where he is director of the Center for Cognitive Studies, ”and I don’t think he was, I’m not making a claim that he would disagree with. I’m not saying that science should do what religion does. I’m saying science should study what religion does.”

From The National Geographic:

The research is one in a string of studies that suggest some time spent getting in tune with the flow of one’s breathing can complement a regimen of pills, diet, and exercise. Meditation is being prescribed for stress, anxiety, infertility, skin diseases, and other ailments. Many medical professionals in the West remain skeptical or are against the use of meditation for therapy. But some are beginning to endorse its benefits, said neuroscientist Sara Lazar, who leads the research at Harvard Medical School in Boston, Massachusetts. “Our hope is that by providing concrete evidence of [meditation’s] benefits, more people will at least try it and see if it is beneficial for them,” she said in an email interview. Lazar presented a paper on the research during a visit of the Dalai Lama, the spiritual leader of Tibet, to the annual meeting of the Society for Neuroscience last November in Washington, D.C.

The Dalai Lama was at the neuroscience meeting to give a talk on the potential for mingling neuroscience with the Buddhist tradition of meditation (map: “Buddhism’s Path to Going Global”).

Jon Wiener in The Nation:

Amos Oz is Israel’s leading novelist, a founder and the best-known voice of Peace Now. He is a bellwether for Israeli doves, for opponents of the occupation who favor Israeli withdrawal from the West Bank and a negotiated two-state solution. In a recent conversation, he assessed the political and diplomatic implications of the Hamas electoral victory.

A week after your book How to Cure a Fanatic was published, Hamas won a historic victory in elections for the Palestinian parliament. Do you regard Hamas as an organization of fanatics?

Fanatics are those people of any faith, color, persuasion or political belief who maintain that the end, whatever end, justifies all the means, including the bloody means. By this criterion I am afraid Hamas is a fanatic organization par excellence.

…

And if Hamas doesn’t change?

If they don’t change, I think it would be wise for Israel to take the conflict upstairs, to neighboring Arab nations, perhaps to the Arab League, and talk about a solution that will then be presented to the Palestinian people in a referendum.

John Lanchester reviews The Google Story by David Vise, in the London Review of Books:

Google is the only multi-billion-dollar company in the world that is also a spelling mistake. Back in the palaeolithic era (that’s the palaeolithic era in the internet sense, i.e. autumn 1997) its co-founders, Larry Page and Sergey Brin, were graduate computer science students at Stanford. They were working on an insanely cool new search engine, wanted to incorporate it as a company, and needed to find a name. David Vise, in his breezy book The Google Story, tells how they came up with one. A fellow graduate student suggested to Page and Brin that they use the name given to what is sometimes, erroneously or metaphorically, called the largest number, 10¹⁰⁰: google. They looked up the name on the internet, found that it wasn’t taken, and registered their brand-new brand, google.com. The next morning they found that the reason the name hadn’t been taken was because it should be spelled googol – and that googol.com had, of course, already been bagged. (It belonged, and still belongs, to a Silicon Valley software engineer and home-brewed beer enthusiast called Tim Beauchamp: ‘The links on this page are a mishmash of eclectic destinations that may be of interest to you. Actually, they may only be of interest to Tim but what the heck. It is his site!’) Lesser men might have considered that a bad omen, but Larry and Sergey are not bad-omen kind of guys. Just over eight years later, Google is the fastest-growing company in the history of the world – with, at the time of writing, a market capitalisation of $138 billion. Larry and Sergey, the Wallace and Gromit of the information age, are worth more than $10 billion each.

Gaia Vince in New Scientist:

Dads-to-be pile on the pounds during their partners’ pregnancy too – at least in some monkey species, new research suggests. The findings may illuminate the biological changes that occur in men to encourage effective fatherhood, since the primates studied are exceptionally good parents.

Pregnancy is something that not all expectant fathers miss out on – male “sympathetic pregnancies” have been reported in humans but never systematically studied. They are often regarded as psychosomatic events.

Now a US team has studied the parental weight patterns of common marmosets and cotton top tamarins – two squirrel-sized, monogamous primate species – from conception to birth. Each month the 25 prospective dads and 33 pregnant mums were weighed. The creatures’ food supply was maintained but not increased during the gestation periods for the marmosets (five months) and tamarins (six months).

“We found that the males gained on average an extra 10% of their body weight during the pregnancy,” says Toni Zeigler who led the research at the University of Wisconsin-Madison National Primate Research Center.

Paul Watkins reviews four books about RFS in the Times Literary Supplement:

David Crane’s exhaustively researched Scott of the Antarctic is a welcome addition to the wealth of reading material about one of Britain’s most famous explorers. It is all here. From “Con’s” early days as a fourteen-year-old naval cadet among the white-gloved eccentrics of the pre-First World War Royal Navy, Crane leads us through the death of Scott’s father and brother and the financial burden placed on him to support his mother and sisters. He traces Scott’s first journey to the Antarctic as captain of HMS Discovery, whose crew, despite many set-backs, returned home having come closer to the Pole than anyone had ever been at that time. Crane describes Scott on his arrival in London, blackened by soot and snow glare, plunged unwillingly into the limelight of royal galas and the lecture circuit. Two years after his marriage to Kathleen Bruce, Scott returns for his second and final voyage to the Antarctic, intent on planting the Union Jack at the South Pole and thus claiming it for Britain. As exhaustion and frostbite take their toll, we read again the immortal words of Oates (“I am just going outside and may be some time”) and the eerily prophetic last line of Scott’s journal, “For God’s sake, look after our people”, almost as if he could foresee the looming carnage of the First World War.

Nathan Bierma in the Chicago Tribune:

In the mid-1980s, Vanden Bosch — my English professor and now my colleague at Calvin College in Grand Rapids, Mich. — coined the word “presticogitation.” It’s a spin-off of the word “prestidigitation,” which means “sleight of hand” and is used to describe magicians (derived from the French “preste,” meaning “nimble, quick,” and the Latin “digitus” for “finger.”)

“Presticogitation” is the cerebral equivalent — “rapid mental processing that commands compliance because of its speed and beauty,” as Vanden Bosch defines it.

“Since the mid-1980s, I’ve been asking students to try to find room for it in their writing,” he says. But Vanden Bosch says his campaign is more than a personal indulgence; it has a teaching purpose.

On June 8, 1954, Alan Turing, a forty-one-year-old research scientist at Manchester University, was found dead by his housekeeper. Before getting into bed the night before, he had taken a few bites out of an apple that was, apparently, laced with cyanide. At an inquest, a few days later, his death was ruled a suicide. Turing was, by necessity rather than by inclination, a man of secrets. One of his secrets had been exposed two years before his death, when he was convicted of “gross indecency” for having a homosexual affair. Another, however, had not yet come to light. It was Turing who was chiefly responsible for breaking the German Enigma code during the Second World War, an achievement that helped save Britain from defeat in the dark days of 1941. Had this been publicly known, he would have been acclaimed a national hero. But the existence of the British code-breaking effort remained closely guarded even after the end of the war; the relevant documents weren’t declassified until the nineteen-seventies. And it wasn’t until the eighties that Turing got the credit he deserved for a second, and equally formidable, achievement: creating the blueprint for the modern computer.

It’s often hard to convince people that Olivo Barbieri’s aerial photographs are real. They look uncannily like hyperdetailed models, absent the imperfections of reality. Streets are strangely clean, trees look plastic, and odd distortions of scale create the opposite effect of what we expect from aerial photography–a complete overview, like military surveillance. “I was a little bit tired of the idea of photography allowing you to see everything,” Barbieri says. “After 9/11 the world had become a little bit blurred because things that seemed impossible happened. My desire was to look at the city again.”

He began the Site Specific project in Rome, before moving on to Amman, Jordan; Las Vegas; Los Angeles; and Shanghai, China. He achieves the distinctive look by photographing from a helicopter using a tilt-shift lens–a method, he says, that “allows me to choose what I really like in focus: like in a written page, we don’t read [it as an] image but one line at a time.” Along with the still photographs, which are exhibited as enormous prints, Barbieri has been making short 35mm films. New York–not surprisingly–is next on his list of cities to tackle.

Today is the birthday of Langston Hughes (February 1, 1902 – May 22, 1967), and the first day of Black History Month:

Born in Joplin, Missouri, James Langston Hughes was a member of an abolitionist family. He was the great-great-grandson of Charles Henry Langston, brother of John Mercer Langston, who was the first Black American to be elected to public office, in 1855. Hughes attended Central High School in Cleveland, Ohio, but began writing poetry in the eighth grade, and was selected as Class Poet. His father didn’t think he would be able to make a living at writing, and encouraged him to pursue a more practical career. He paid his son’s tuition to Columbia University on the grounds he study engineering. After a short time, Langston dropped out of the program with a B+ average; all the while he continued writing poetry. His first published poem was also one of his most famous, “The Negro Speaks of Rivers”, and it appeared in Brownie’s Book. Later, his poems, short plays, essays and short stories appeared in the NAACP publication Crisis Magazine and in Opportunity Magazine and other publications.

I, too, sing America.

I am the darker brother.
They send me to eat in the kitchen
When company comes,
But I laugh,
And eat well,
And grow strong.

Tomorrow,
I’ll be at the table
When company comes.
Nobody’ll dare
Say to me,
“Eat in the kitchen,”
Then.

Besides,
They’ll see how beautiful I am
And be ashamed–

I, too, am America.

Malcolm Gladwell in The New Yorker:

In epidemiological studies of dog bites, the pit bull is overrepresented among dogs known to have seriously injured or killed human beings, and, as a result, pit bulls have been banned or restricted in several Western European countries, China, and numerous cities and municipalities across North America. Pit bulls are dangerous.

Of course, not all pit bulls are dangerous. Most don’t bite anyone. Meanwhile, Dobermans and Great Danes and German shepherds and Rottweilers are frequent biters as well, and the dog that recently mauled a Frenchwoman so badly that she was given the world’s first face transplant was, of all things, a Labrador retriever. When we say that pit bulls are dangerous, we are making a generalization, just as insurance companies use generalizations when they charge young men more for car insurance than the rest of us…

On her homepage, Nancy Cartwright has an interesting working paper, entitled “No God, No Laws”.

My thesis is summarized in my title, ‘No God, No Laws’: the concept of a law of Nature cannot be made sense of without God. It is not as dramatic a thesis as it might look, however. I do not mean to argue that the enterprise of modern science cannot be made sense of without God. Rather, if you want to make sense of it you had better not think of science as discovering laws of Nature, for there cannot be any of these without God. That depends of course on what we mean by ‘laws of Nature’. Whatever else we mean, I take it that this much is essential: Laws of Nature are prescriptive, not merely descriptive, and – even stronger – they are supposed to be responsible for what occurs in Nature. Since at least the Scientific Revolution they are also supposed to be visible in the Book of Nature, not writ only on stone tablets nor in the thought of God…

My claim here is that neither of these features can be made sense of without God; this despite the fact that they are generally thought to provide some autonomy of the world order from God.

But she does offer a way out.

From the Chronicle of Higher Education:

In 55 BC, the Roman leader Pompey staged a combat between humans and elephants. Surrounded in the arena, the animals perceived that they had no hope of escape. According to Pliny, they then “entreated the crowd, trying to win its compassion with indescribable gestures, bewailing their plight with a sort of lamentation.” The audience, moved to pity and anger by their plight, rose to curse Pompey — feeling, wrote Cicero, that the elephants had a relation of commonality (societas) with the human race.

In 2000 AD, the High Court of Kerala, in India, addressed the plight of circus animals “housed in cramped cages, subjected to fear, hunger, pain, not to mention the undignified way of life they have to live.” It found those animals “beings entitled to dignified existence” within the meaning of Article 21 of the Indian Constitution, which protects the right to life with dignity. “If humans are entitled to fundamental rights, why not animals?” the court asked.

We humans share a world and its scarce resources with other intelligent creatures. As the court said, those creatures are capable of dignified existence. It is difficult to know precisely what that means, but it is rather clear what it does not mean: the conditions of the circus animals beaten and housed in filthy cramped cages, the even more horrific conditions endured by chickens, calves, and pigs raised for food in factory farming, and many other comparable conditions of deprivation, suffering, and indignity. The fact that humans act in ways that deny other animals a dignified existence appears to be an issue of justice, and an urgent one.

Charles Q. Choi in Scientific American:

The long-range weather forecasts that warned of where Hurricane Katrina would strike depended on data from polar satellites. They capture not only details over the Arctic and Antarctic but also virtually every point on the planet’s surface as the world turns under them. Now the replacements for the aging U.S. military and civilian fleet are in jeopardy. The program is as much as $3 billion over budget, and the launch of the first replacement satellite is as many as three years behind schedule.

Gary King in PSOnline:

A decade ago this journal published a symposium on replication policies in political science. The symposium began with an article I wrote entitled “Replication, Replication,” and was followed by opposing and supporting comments by 19 others (King, 1995). The debate over proper policies continued for a few years in subsequent issues of the journal and a variety of other public fora. Since then, many journals in political science have adopted some form of a data sharing or replication policy. Some strongly recommend or expect data sharing and some require it as a condition of publication. The editors of the major international relations journals have collectively written and committed themselves to a strong standard minimum replication policy (Gleditsch et al. 2003). Most important, numerous individual scholars now regularly share their data, produce replication data sets, put these data sets on their web sites, send them to the ICPSR and other archives, or distribute them on request to other scholars. Scholars sometimes worry about being “scooped,” about maintaining the confidentiality of their respondents, or about being proven wrong, but since authors who make their data available are more than twice as cited and influential as those who do not (Gleditsch, Metelits, and Strand 2003), the strong trend toward data sharing in the discipline should not come as a surprise.

The broader scientific community both collectively and in many other individual fields is also moving strongly in the direction of participating in or requiring some form of data sharing. Recipients of grants from the National Science Foundation and the National Institutes of Health now are required to make data available to other scholars upon publication or within a year of the termination of their grant. Replicating, and thus collectively and publicly validating, the integrity of our published work is often still more difficult than it should be, and some still oppose thewhole idea, but our discipline has made substantial progress.

Jack Shafer in Slate:

It’s not Ted Koppel’s fault that the New York Times has made him a Times contributing columnist. As Koppel writes in yesterday’s (Jan. 29) debut column, “And Now, a Word for Our Demographic,” the invitation came from an “editor friend of mine,” so the fault belongs to whoever assigned, accepted, and edited or rewrote Koppel’s self-indulgent, self-congratulatory, late-to-the-party, and punishingly obvious 1,500-word piece about the state of television news. (It’s bad.) It’s not even Koppel’s fault if he thinks he’s any good at this columnist thing, when he isn’t. If we were to belittle every person who stretched his talents until they pop, we’d have little time for anything else.

So, my critique isn’t personal, it’s institutional. Based on what did the Times think Koppel could write a compelling newspaper column? Did they not see disaster in this piece?

From MSNBC:

Some types of ongoing, inexplicable pain like arthritis are caused by intact, healthy nerve fibers rather than those that have been damaged, a new study finds. The discovery surprised researchers. It had not been made before partly because studies of chronic pain have tended to focus on the damaged nerves. The new understanding, reported in the Jan. 25 issue of the journal Neuroscience, could help scientists develop new types of painkillers.

The evidence so far applies only to ongoing pain associated with nerve injury and inflammation, although it may turn out to be more widely applicable, said Sally Lawson, a professor of physiology at the University of Bristol in Britain.
