Smarty pantses

Beyond the science fair. Behind a veneer of shoddy web-design lies a brilliant idea: getting grade- and high-school students to do actual scientific work. For example, "10 students from New York, Texas and Virginia joined three World War II veterans and a retired railroader from Virginia" and discovered a way to make walls self-sterilize. The guy behind it is Carl Vermeulen.

Science, race, and genetics

The Natural History of Ashkenazi Intelligence (PDF). A fascinating new theory from physicist turned renegade evolutionary theorist, Gregory Cochran (see this Atlantic Monthly cover story on Cochran's already path-breaking germ theory of disease), and genetic anthropologist Henry Harpending, proposes that a unique evolutionary history, and a number of improbably clustered neurologically related genetic diseases among Ashkenazi Jews could help explain their incredible intelligence test scores and extraordinary intellectual achievements (e.g. Ashkenazi Jews are 3% of the American population but win 27% of the Nobel Prizes). The paper is set for publication in the Journal of Biosocial Science, and is already getting major press in the New York Times and The Economist. Does the recent Harvard fracas over Larry Summers herald a new "arms race" in academic debate about genetics, man and society for the 21st century? [compelling post by Jason]

The quake felt 'round the world

Worth picking up if you have a library with a subscription. The May 20th issue of Science was devoted to the Sumatra-Andaman Earthquake of December 24 describing the full power of that event, the most powerful recorded since the deployment of modern electronic sensors. The multiple effects claimed include swarm earthquakes in Alaska, a shock wave that moved every place on Earth a centimeter, and resonant waves continuing weeks after the event. It is also the the longest rupture recorded and took over an hour to complete. Animated simulations of aspects of the event are linked through PhysOrg.com.

Scientific Americans

The US Postal Service has issued a series of postage stamps honoring great American scientists including: Josiah Willard Gibbs, thermodynamicist best known for the Gibbs Phase Rule; Barbara McClintock, geneticist who showed genes could transpose within chromosomes; John von Neumann, mathematician who made significant contributions in game theory and computer science; and Richard Feynman, infamous physicist best remembered for his work on quantum electrodynamics, the Manhattan Project, Feynman Diagrams, and his testimony at the Space Shuttle Challenger hearings.

"Family Values, My Ass!"

"Family Values, My Ass!" That article in the Lexington Herald-Leader inspired me to look up the Nation article it referred to. Now I'm beginning to see why many women won't go to "evangelical Christian" MDs: this guy Hager (previously brought up on MetaFilter in 2003, in fact twice, and then again in 2004) is strongly anti-abortion -- so pro-conception that he tried to keep the "morning-after pill" known as "Plan B" away from women -- but he's apparently pro- sodomy and pro-rape. It almost sounds like fiction.

How Does Your Water Feel?

The Hidden Messages in Water? Masaru Emoto claims that water has the ability "to absorb, hold, and even retransmit human feelings and emotions. Using high-speed photography, he found that crystals formed in frozen water reveal changes when specific, concentrated thoughts are directed toward it. Music, visual images, words written on paper, and photographs also have an impact on the crystal structure." The theory may be suspect, but the photos are beautiful.

Christian fundamentalists and radical Islam: Two great tastes that go together over creationism!

"Set your irony meters on maximum." All this week, a three-member subcommittee of the Kansas State Board of Education is holding hearings on how to teach science. [background] Creationists, er, advocates of "intelligent design," are using it to bootstrap their claim that evolution through natural selection and creationism are two sides of a story. While many scientists are boycotting what one newspaper is calling "Barnum on steroids," IDers have brought out the big guns -- including one Mustafa Akyol, a Turkish, Muslim, newspaper columnist with a Masters in history and a close associaton with a group that presents evolution "as a conspiracy of the Jewish and American imperialists to promote new world order and fascist motives."

a glitch of the electronics

Junk Science. George Monbiot has a critical look at some the claims put forward by "climate change" deniers. There's lots of interesting refutation, with some amusement: "But there was still one mystery to clear up. While Bellamy’s source claimed that 55% of 625 glaciers are advancing, Bellamy claimed that 555 of them – or 89% – are advancing. This figure appears to exist nowhere else. But on the standard English keyboard, 5 and % occupy the same key. If you try to hit %, but fail to press shift, you get 555, instead of 55%. This is the only explanation I can produce for his figure. When I challenged him, he admitted that there had been “a glitch of the electronics”."

From the followup department: Global dimming? It stopped. "We see the dimming is no longer there," said Dr. Martin Wild, a climatologist at the Swiss Federal Institute of Technology in Zurich and the lead author of one of three papers analyzing sunlight that appear in today's issue of the journal Science. "If anything, there is a brightening." As always, use bugmenot to bypass registration.

Gender Based Brain Research

A review of the current state of gender based brain research shows that women and men differ both in the way their brains are constructed and in how they function.
..correlation between brain region size in adults and sex steroid action in utero suggests that at least some sex differences in cognitive function do not result from cultural influences or the hormonal changes associated with puberty--they are there from birth.
Treatment for such things as schizophrenia and depression will likely have gender specific variations in the future. Previously, brain research that examined gender differences was considered controversial because it was argued that the results might give rise to more sex discrimination against women. That view may be changing.

The Dance of the Manakin

Manakins (Manacus sp.) are small, colorful sparrow-sized birds found all over Central and South America. Manakin males engage in elaborate courtship dances, including rhythmic sounds they produce with their wings. No one really knew how the birds made this sounds, until Kimberly Bostwick, Curator of Birds and Mammals at the Cornell University Museum of Vertebrates, went into the jungles of Ecuador to film the birds at 1000 frames per second. As it turns out, different species of manakin use entirely different motion to produce the sounds. The Journal of Experimental Biology has published the results, complete with videos. Mark Barres, who studies avian genetic population structures at the Univ. of Wisconsin, has also filmed the mating dance of the Manakins [.mov].

Desktop Fusion

Putterman also suggests the crystals could be used as microthrusters for tiny spacecraft. By accelerating deuterium in one direction, the spacecraft would be propelled in the opposite direction.

We cannot leave technology to the technologists; we must all embrace it. We have lived through a revolution in which technology has affected all our lives and altered our societies for ever."

Self Experimentation is Credible Science??

"Chance favours the prepared mind" (Pasteur) but can a science of n = 1 be credible? Seth Roberts is a UCBerkeley Psychology Professor who is into generating novel scientific ideas from self-experimentation. He has written a very serious journal article (abstract) in Behaviour and Brain Science in which he alleges: Seeing faces in the morning on television decreased mood in the evening and improved mood the next day . . . Standing 8 hours per day reduced early awakening and made sleep more restorative . . . Drinking unflavored fructose water caused a large weight loss that has lasted more than 1 year.. among other things.

White Shark Released

White Shark Released from Monterey Bay Aquarium after six months in captivity. In the last week, aquarists noted several incidents of what they considered to be active hunting of other exhibit animals, and they became substantially more concerned about the well-being of the other fishes. She was not released because of any injury or health problem. At the time of her release, she was 6'-4" long and weighed 162 pounds.

Chaz has a posse!

Scientific American to stop reporting science, more creationism. There's no easy way to admit this. For years, helpful letter writers told us to stick to science. They pointed out that science and politics don't mix. They said we should be more balanced in our presentation of such issues as creationism, missile defense and global warming...But spring is in the air, and all of nature is turning over a new leaf, so there's no better time to say: you were right, and we were wrong.

Secrets of the X chromosome, revealed!

Female X chromosome 'cracked' - "The discovery, by an international consortium of scientists, shows that females are far more variable than previously thought and, when it comes to genes, more complex than men." Nature reports two new studies; one on the complete sequencing of the X chromosome for humans, which sheds some light on how sex evolved and how women differ from men, and another on how women express many genes from X chromosomes previously thought dormant.
