Humans do it, bacteria do it, even viruses do it: they make copies of themselves. Now US researchers have built a flexible robot that can perform the same trick. It’s not the first self-replicating robot ever built, says Hod Lipson of Cornell University, who led the study. But previous machines with the capacity for copying themselves have been very simple, often spreading out in only two dimensions. And more complex devices existed only in computer simulations, not reality.
Lipson’s robot consists of four cubes, each 10-cm to a side, which are sliced diagonally into halves that can rotate against each other. This allows the robot to change shape, he reports in Nature. Provided it is fed with cubes, the robot can create a copy of itself within a few minutes.

From MSNBC:

Young male birds may break rigid rules for song structure, but they quickly shape up when it’s time to attract a mate. During the first half of their youth, male canaries raised alone in soundproof cages can learn to precisely imitate computer-generated songs. As spring nears, however, the canaries literally “change their tune” by reorganizing the structure of their songs so that they conform to the rules of adult canary songs and the expectations of potential mates. This new study appears in Friday’s issue of the journal Science, published by AAAS, the nonprofit science society.

“Short of driving a Mercedes-Benz, it’s what a bird can do to say ‘I’m such a good finder of food that I have the time to make these long songs,’” explained Rockefeller University’s Fernando Nottebohm, another author of the Science research.

Zafar Abbas for The BBC:

The Pakistan Air Force (PAF) academy has been all-male for more than 55 years – but now it is going through major change. Women are now allowed to enrol on its aerospace engineering and fighter pilot programmes and are doing rather well. To the great surprise of many men, some of the female recruits will soon start flying jet-engine planes.

But when one male cadet said the women should be shown compassion, female cadet Saman Ahmed was swift to say they were there to compete on equal terms. “We don’t expect compassion, we don’t get compassion, and we don’t want compassion,” she said. And this confidence is not without reason for Cadet Ahmed has already won praise in her engineering studies, beating both men and women. Her excellence is not confined to the classroom, either. During a rifle exercise, I watched as she shot all five bullets right in the bull’s eye.

From The Village Voice:

“Isn’t that a bit like a Catholic marrying a Protestant back where I’m from?” asks the Irish officer at the Canadian office as Amitava Kumar, a Hindu writer from India, and his soon-to-be wife, Mona, a Pakistani Muslim, submit their marriage application. It’s much worse, according to Kumar’s Husband of a Fanatic, the reciprocity of hate between South Asia’s Hindu and Muslim communities having reached new levels of hostility over the last decade or so. Inspired by Underground, Haruki Murakami’s book on Tokyo’s 1995 sarin gas attack, Kumar tries to get to the root of this animosity via the personal experiences of victims. He visits scenes of carnage and sites of remand and retribution, and attempts to discourse with casualties and aggressors in places as distant as India, South Africa, and Queens.

From The Chronicle of Higher Education:

On March 16, the Kansas Legislature heatedly debated a bill that would criminalize all stem-cell research in the state. Evangelical-Christian politicians and conservative lawmakers argued with molecular biologists and physicians from the University of Kansas’ medical school about the morality of therapeutic cloning.

Up against a substantial audience of vocal religious conservatives, William B. Neaves, CEO and president of the Stowers Institute for Medical Research, a large, privately financed biomedical-research facility in Kansas City, began his impassioned defense of the new research by giving his credentials as “a born-again Christian for 30 years.” Barbara Atkinson, executive vice chancellor of the University of Kansas Medical Center, tried to articulate the difference between “a clump of cells in a petri dish” and what several hostile representatives repeatedly interrupted to insist is “early human life.” Clearly, in this forum, language mattered. Each word carried wagonloads of moral resonance.

I am a literature professor. I was at the hearing because I am also chairwoman of the pediatric-ethics committee at the University of Kansas Medical Center. I listened to the debates get more and more heated as the positions got thinner and more polarized, and I kept thinking that these scientists and lawmakers needed to read more fiction and poetry. Leon R. Kass, chairman of the President’s Council on Bioethics, apparently feels the same way. He opened the council’s first session by asking members to read Hawthorne’s story “The Birthmark,”and he has since published an anthology of literature and poetry about bioethics issues.

The fight in Kansas (the bill was not put to a vote) is in some ways a microcosm of what has been happening around the country.

200 researchers and numerous robots of different types have gathered together in GeorgiaTech for the 2005 RoboCup US open competition, where robot dogs play soccer, and humans on segways cooperate with robots to win games. The BBC reports:

“There is a serious side to the 2005 RoboCup US Open but there is also a lot of fun to be had watching robot dogs playing football. The event has become the robotic version of the football World Cup and is a fertile meeting ground for robot researchers. The software that drives the footballing canines has practical real-world applications as well. Organisers plan the ultimate human versus robot football game in 2050.”

James Surowiecki in The New Yorker:

In the summer of 1924, a Kansas City band called the Coon-Sanders Original Nighthawk Orchestra did something unusual: it went on tour. Popular as live music was, bands in those days tended to serve as house orchestras or to play long stands in local clubs; there was hardly even a road to go on. But Jules Stein, a booking agent from Chicago, convinced the Nighthawk Orchestra that it could make more money by playing a different town every night. The tour, which lasted five weeks, was a smash. Soon, bands all over the country were hitting the road to play ballrooms and dance halls.

Stein’s original vision hasn’t changed much, despite some modifications over the years—parking lots, hair spray, the disposable lighter…

Larry Stewert reviews The Newtonian Moment: Isaac Newton and the Making of Modern Culture by Mordechai Feingold, in American Scientist:

The exhibits of Newton’s works at Cambridge University Library in 2001 and at the New York Public Library from October 8, 2004, to February 5, 2005, were of note, among other reasons, for the attention they drew to a December 2004 auction of rare Newton manuscripts. Mordechai Feingold has, meanwhile, created a lavishly illustrated and immensely entertaining companion volume to the New York display of Newton’s great achievement. The book serves to demonstrate that the rationalism of the European Enlightenment, which was marked by upheaval in America and in France, was defined in such large measure by the conception and diffusion of Newton’s great works in mathematics and physics that the epoch could be viewed as the Newtonian Moment.

Here is a Newton deified, not only in a state funeral at Westminster Abbey (rare for a philosopher) but also by endless numbers of paintings and engravings of the great man—some of which Newton himself distributed. Gentlemanly experimental philosophers, even amateur ones, later took pains when having their own portraits painted to have apparatus and portraits of Newton and Bacon in the background. Thomas Jefferson was so smitten that he obtained one of the few copies of Newton’s death mask made in 1727. The colossus of Newton strode across the 18th century, subduing nature, even as Alexander Pope eulogized him with this couplet: “Nature, and Nature’s Laws lay hid in Night. / God said, ‘Let Newton be!’ and all was Light.”

Will Knight in New Scientist:

A gun that spits out ball bearings after spinning them to extreme speeds is being developed by a US inventor. The novel design has already caught the imagination of some defence industry experts.

The weapon, called DREAD, was invented by Charles St George, a veteran of the US firearms industry who founded the company Leader Propulsion Systems to promote the idea. He claims a major US defence company has shown an interested in developing it further and has produced a promotional video showing a prototype in action, which can be seen here (Quicktime). He says a new prototype will be developed in August 2005.

Denis Dutton reviews The Seven Basic Plots: Why We Tell Stories by Christopher Booker, in the Washington Post:

In the summer of 1975, moviegoers flocked to see the story of a predatory shark terrorizing a little Long Island resort. The film told of how three brave men go to sea in a small boat and, after a bloody climax in which they kill the monster, return peace and security to their town — not unlike, Christopher Booker observes, a tale enjoyed by Saxons dressed in animal skins, huddled around a fire some 1,200 years earlier. Beowulf also features a town terrorized by a monster, Grendel, who lives in a nearby lake and tears his victims to pieces. Again, the hero Beowulf returns peace to his town after a bloody climax in which the monster is slain.

Such echoes have impelled Booker to chart what he regards as the seven plots on which all literature is built. Beowulf and “Jaws” follow the first and most basic of his plots, “Overcoming the Monster.” It is found in countless stories from The Epic of Gilgamesh and “Little Red Riding Hood” to James Bond films such as “Dr. No.” This tale of conflict typically recounts the hero’s ordeals and an escape from death, ending with a community or the world itself saved from evil.

Booker’s second plot is “Rags to Riches.”

A while ago I posted about an AI that was remarkably good at 20 questions.  Now the AI is available in a hand held ball.

“Last year, after 1 million rounds of 20 questions online, the neural net had accumulated 10 million synaptic associations. It has a 73% success rate of guessing what you thought. Burgener then compressed the 20Q code to run on a chip, and had the neural net select 2,000 of the most popular 10,000 objects it then knew about. He then had the neural net select out the most useful 250,000 synaptic connections related to those 2,000 objects, and hard wired that learning into the chip in the orb. In other words, this sphere is a handheld version of Burgener’s Twenty Questions web site. (Because it knows about fewer objects than the web version, it gets confused less often, so its success rate is ironically higher.)

The toy is remarkable. Because it is so small, so autonomous, its intelligence is shocking to the unprepared. Most children can’t stump it, and if you stick to objects it will stump smart adults about 80% of the time with 20 questions and most of the time with an additional 5 questions.”

‘When the Central Line opened in 1900, it introduced hanging straps and proper windows, but drew renewed complaints of bad air. A bureaucrat in the Sudan Political Service said that it smelled like crocodile’s breath. The Central Railway retorted: ‘It has been practically demonstrated by physiological and chemical experiments that a live man might be sealed up in a lead coffin for half an hour without any resultant feeling of oppression – I say nothing of depression – provided he were treated as frozen mutton in a cold store, so that the air he breathed might still remain cold.’ Not until the 1930s was the atmosphere of the Tube made palatable by means of blowing filtered, ozonised air into it from the outside world.’

From James Meek’s LRB essay on the Tube, “Crocodile’s Breath.”

British Modernism has not been served well by American critics and readers. Preoccupied by American poetry’s own version of family court—who are the true heirs of William Carlos Williams, Charles Olson, or even Robert Lowell? when will the prodigal Stein finally come back from Europe and take her place at the head of the table?—we have been content merely to nod approvingly at the likes of Basil Bunting and David Jones. But as the recent publication of J.H. Prynne’s Poems, Tom Raworth’s Collected Poems, and the many collected and selected volumes streaming out of Salt Publishing remind us, the story of British Modernism in America is still a work in progress.

Add to that story W.S. Graham’s New Collected Poems, which not only returns Graham to the central narrative of 20th-century British poetry but should also mark his introduction to the United States as a major lyric poet.

From an interesting review by Brian Kim Stefans at Boston Review. Here’s a poem by Graham:

                 Listen. Put on morning.
                 Waken into falling light.
                 A man’s imagining
                 Suddenly may inherit
                 The handclapping centuries
                 Of his one minute on earth.
                 And hear the virgin juries
                 Talk with his own breath
                 To the corner boys of his street.
                 And hear the Black Maria
                 Searching the town at night.
                 And hear the playropes caa
                 The sister Mary in.
                 And hear Willie and Davie
                 Among bracken of Narnain
                 Sing in a mist heavy
                 With myrtle and listeners.
                 And hear the higher town
                 Weep a petition of fears
                 At the poorhouse close upon
                 The public heartbeat.
                 And hear the children tig
                 And run with my own feet
                 Into the netting drag
                 Of a suiciding principle
                 Listen. Put on lightbreak.
                 Waken into miracle. . . .

From The Boston Globe:

BARBARA EHRENREICH is best known these days for “Nickel and Dimed: On (Not) Getting By in America,” her biting 2001 bestseller about going undercover in a variety of low-wage jobs. But “Nickel and Dimed” was actually her 12th book. In her long career, Ehrenreich has often investigated how capitalism unmoors individual lives, whether by treating low-wage workers (especially women) as disposable things (“Nickel and Dimed’’) or encouraging women to sell their mother-love (“Global Woman: Nannies, Maids, and Sex Workers in the New Economy,” co-edited with Arlie Russell Hochschild).

This Tuesday at the Radcliffe Institute, she will expand on the theme in a lecture titled ‘‘Weird Science: Challenging Sexist Ideology Since the 1970s.” – E.J. GRAFF

IDEAS: Alessandra Stanley wrote in The New York Times a few months ago that feminism lasted for 15 minutes but the backlash against it has lasted for 30 years. How would you compare women’s status today to our status in 1975?

EHRENREICH: Oh, I think there’s just been enormous changes for the good, on the whole. A kind of feminist consciousness has permeated a lot of our culture and is not any more regarded as the property of “feminism.” Women who aren’t self-proclaimed or self-identified feminists will still be opposed to unequal pay for unequal work, or will stand up against perceived insults to women.

From The Guardian:

What is a gene? Scientists eager to uncover genes for heart disease, autism, schizophrenia, homosexuality, criminality or even genius are finding that their quarry is far more nebulous than they imagined. Uncovering the true nature of genes has turned biology on its head and is in danger of undermining the whole gene-hunting enterprise. 

The first clues turned up in study of the cell’s metabolic pathways. These pathways are like Britain’s road networks that bring in raw materials (food) and transport them to factories (enzymes) where the useful components (molecules) are assembled into shiny new products (more cells). A key concept was the “rate-limiting step”, a metabolic road under strict traffic control that was thought to orchestrate the dynamics of the entire network.

Biotechnologists try to engineer cells to make products but their efforts are often hindered, apparently by the tendency of the key genes controlling the rate-limiting steps to reassert their own agenda. Scientists fought back by genetically engineering these genes to prevent them taking control. When they inserted the engineered genes back into the cells they expected to see an increase in yields of their products. But they were disappointed. The metabolic pathways slipped back into making more cells, rather than more products.

From The Edge:

On April 22, 2005, Harvard University’s Mind/Brain/Behavior Initiative (MBB) held a defining debate on the public discussion that began on January 16th with the public comments by Lawrence Summers, president of Harvard, on sex differences between men and women and how they may relate to the careers of women in science. It’s interesting to note that since the controversy surrounding Summers’ remarks began, there has been an astonishing absence of discussion of the relevant science…you won’t find it in the hundreds and hundreds of articles in major newspapers; nor will find it in the Harvard faculty meetings where the president of the leading University in America was indicted for presenting controversial ideas.

But unlike just about anything else said about Summers’ remarks, the debate, “The Science of Gender and Science”, between Harvard psychology professors Steven Pinker and Elizabeth Spelke, focused on the relevant scientific literature. It was both interesting on facts but differing in interpretation.

Who won the debate? Make up your own mind. Watch the video, listen to the audio, read the text and check out the slide presentations.

Shirin Neshat writes in The Art Newspaper:

With the Islamic revolution (1979) and the political isolation that followed, Iran fell into a deep cultural crisis. Artists were suddenly faced with a dictatorship that essentially denied artistic freedom of expression, imposed severe Islamic codes and made Western culture taboo. As the borders closed and new boundaries were established by the government, artists had no choice but to look inward to their imagination, to transform this isolation into an artistic resolution. Consequently, we have seen an outpouring of artistic production in literature, film, theatre, visual arts and music. We find bold attempts by artists who have not only challenged the authority, but have pioneered an authentically Iranian, non-Western aesthetic; which, while remaining mindful of the crippling social, political and religious realities of their country, aims at transcending national boundaries, to become universally significant.

Jennifer Viegas in New Scientist:

Smelling a male pheromone prompts the same brain activity in homosexual men as it does in heterosexual women, a new study has found. It did not excite the sex-related region in the brains of heterosexual males, although an oestrogen-derived compound found in female urine did.

The testosterone-derived chemical AND is found in male sweat and is believed to be a pheromone. It activated the anterior hypothalamus and medial preoptic area of gay men and straight women alike. Researchers led by Ivanka Savic at the Karolinska University Hospital in Sweden believe this brain region integrates the hormonal and sensory cues used in guiding sexual behaviour.

The research demonstrates a likely link between brain function and sexual orientation, Savic suggests. But she told New Scientist that the study “does not answer the cause-and-effect question”.

So the brain-activation of gay men by AND may contribute to sexual orientation of those men, or simply be the result of their orientation and sexual behaviour. She added that the brain scans revealed no anatomical differences between any of the participant’s brains.
