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.

Africa Must Commit To Biosecurity Measures
August 22, 2007 10:12 AM - Chandre Gould, SciDevNet

Africa - The threat of biotechnology misuse has implications for the development of science and technology in Africa, argue Chandre Gould and colleagues. Recent African Union summits have identified science and technology as key future drivers for development, and increased investment is being welcomed by African leaders — particularly in areas such as biotechnology. But the growth of the biotechnology industry internationally has raised some important concerns about biological safety issues.

In the timeless quest for healthier, younger looking skin, scientists from the University of Cincinnati and Tokyo Medical University have made an important discovery toward manipulating skin tone and color.

Using Hi-Tech Tools To Rescuing Recorded Sound from Silence
August 21, 2007 01:35 PM - Kathleen M. Wong, UC Berkeley

While listening to National Public Radio in 2000, Carl Haber learned that the Library of Congress had a big problem. The Library's audio collection, which spans the 130-year history of recorded sound, includes the soaring tenor of Enrico Caruso, the speeches of Teddy Roosevelt, and the voices of Native Americans from now-vanished tribes. These echoes of a bygone era were recorded on media such as wax cylinders and shellac and lacquer discs. But many are now too fragile to play in their original format; the pressure of a stylus or phonograph needle could cause irreversible damage. The archivists needed a means to preserve the recordings without injuring them further.
