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”."

Singularity

According to the developmental spiral we are heading towards an unfathomable point in time known as singularity. Could the futurists and science fiction writers such as Vernon Vinge be right?

From the follow-up department

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.
Ok, so I know nothing about physics, apart from what I learned getting beat up in grade school, but this seems both legit and cool. Here's a MeFi discussion of the other kind of desktop fusion, you know, the kind with the bubbles. A picture of the bubble machine.

Reith Lecture 2005

Reith Lecture 2005: The Triumph of Technology Lord Broers -In the five lectures, he sets out his belief that technology can and should hold the key to the future. He says: "It is time to wake up to this fact. Applied science is rivalling pure science both in importance and in intellectual interest. 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. The entire paper was published along with formal peer reviews and a response from Roberts [warning: 63page .pdf] (Peers came down about 50:50 in support/dissenting) A short review/discussion of the article and followup and a short followup Roberts paper with experimental replications (pdf) via

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.

An evolutionary basis for altruism. These findings suggest that true altruism, far from being a maladaptation, may be the key to our species' success by providing the social glue that allowed our ancestors to form strong, resilient groups. Sharing isn't just caring, it's surviving.

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.

Cage Match: Gravity Leakage vs. Dark Matter

In 1962, Thomas Kuhn published The Structure of Scientific Revolutions. It questioned not only the "progressive" model of scientific history, but also bled over into other disciplines and brought into question human perception of just about everything else. (coining the questionable phrase "paradigm shift" in the process.)

One of the most interesting shifts came in the battle about the (not totally forgotten) aether. A modern day equivalent might be "dark matter," an undetected form of matter that explains some of the quirky behavior of gravity. Or, it could all be gravity leakage.
Let the battle begin! (The winner might just set the course of astrophysics for the next generation, or even lead to the holy grail.)
