Scientists Re-Trace Evolution Of Genes
August 24, 2007 05:08 PM - University of Oregon
EUGENE, Ore. — Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. "Never before have we seen so clearly, so far back in time," said project leader Joe Thornton, an evolutionary biologist at the University of Oregon. "We were able to see the precise mechanisms by which evolution molded a tiny molecular machine at the atomic level, and to reconstruct the order of events by which history unfolded."
Cancer Drugs That Block Blood Vessel Growth From Inside Cells May Lead to Serious Long Term Health Problems
August 24, 2007 04:48 PM - UCLA
Los Angeles - Angiogenesis inhibitors, drugs that block a tumor's development of an independent blood supply, have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy. However, a new study by researchers at UCLA's Jonsson Cancer Center has shown that one method of blocking blood-supply development could result in serious and potentially deadly side effects.
Hubble And Keck Gives New View Of Uranus' Rings

Ancient Organisms Discovered in Canadian Gold Mine
August 23, 2007 09:00 AM - University of Illinois Chicago
Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task.
NASA And U.S. Forest Service Partner On Wildfire Imaging Mission
August 22, 2007 08:44 PM - Paul Schaefer, ENN
EDWARDS AIR FORCE BASE, Calif. - NASA and the U.S. Forest Service have begun tests of their aerospace agency-developed technologies to improve wildfire imaging and mapping capabilities. From mid-August through September, NASA's Dryden Flight Research Center is conducting flights of a remotely piloted unmanned aircraft system to demonstrate the capabilities of its sophisticated new imaging and real-time communications equipment. The first flight of the series Aug. 16 captured images of California wildfires, including the Zaca Fire in Santa Barbara County. The aircraft carried instruments that collected data while flying more than 1,200 miles over a 10-hour period.
New Technology Prmoises Dramatic Chip-Cooling Potential For Future Computers
August 22, 2007 01:20 PM - Emil Venere, Purdue University
WEST LAFAYETTE, Ind. - Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. The Purdue University researchers, in work funded by Intel Corp., have shown that the technology increased the "heat-transfer coefficient," which describes the cooling rate, by as much as 250 percent.
