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.

) 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]

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."

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.

T. rex soft tissue!
No, not dino-kleenex -- scientists have extracted organic compounds from a fossilized Tyrannosaurus rex bone. Can Jurassic Park
be far behind?

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.

To the Lost City.
Researchers at the University of Washington discovered an undersea hydrothermal vent field that promises new information about the origins of life. A monthlong research trip
in 2003, documented online, yielded results that have just now been published in Science
(subscribers only, sorry). The UW's Lost City site has much of interest, including an online journal
from the excursion; pictures and video are also available here
