VA-Stanford Study Identifies Effective Anthrax Treatment

When spores sent through the mail in 2001 caused 11 people to contract anthrax – ultimately killing five of them – infectious disease specialists noted that the death rate was substantially lower than the historical mortality rate, which approached 100 percent. Many assumed that access to modern intensive care units and more powerful antibiotics made the difference.

But after completing the most comprehensive review of anthrax cases ever conducted, researchers at the Veterans Aff

A better tool to study role of iron in Alzheimer’s, Parkinson’s

Engineers have found a way to pinpoint and identify the tiny iron oxide particles associated with Alzheimer’s and other neurodegenerative diseases in the brain.

The technique is likely to accelerate research on the cause of the diseases and could lead to the first diagnostic procedure for Alzheimer’s in patients while they are alive.

“We’re the first to be able to tell you both the location of the particles and what kind of particles they are,” said Mark Davidson, a Unive

New Modeling Technique Aims to Reduce Aircraft Noise

Newly published research by a Princeton engineer suggests that understanding how air travels across the sunroof of a car may one day make jet engines less noisy.

Clarence Rowley, an assistant professor of mechanical and aerospace engineering, did not actually conduct his experiments on a sunroof. Rather, he and collaborators used computer simulations and subsonic wind tunnels at Princeton and at the U.S. Air Force Academy in Colorado Springs, to experiment with models that rese

Warming Makes Polar Bear “Brutalized”

During migration, polar bears reach mainland by ice. The exit to the coast is extremely important for them, as bears find food there – remains of walrused perished at coastal breeding-grounds, remainder of aboriginal population’s sea fishery, ringed seal (Pusa hispida). Pregnant females come out to the locations of hiding into maternity dens. Lagging of ice sheet arrival in the south makes a lot of bears reach mainland by swimming.

In 2005, reports appeared that polar bears were more frequ

New Radio Tech Enhances Inventory Management with RFID

Research financiers Vinnova in Sweden and Tekes in Finland have granted SEK 6 million to a Nordic research project in printed electronics and RFID, Radio Frequency Identification. Eventually RFID will replace bar codes on packaging, for example. With the help of radio technology, many items can then be identified at the same time, which is of great value in taking inventory, for instance. The research project was initiated by a research team in RFID technology at Mid Sweden University.

Human-Chimp Differences Linked to Gene Regulation Insights

The vast differences between humans and chimpanzees are due more to changes in gene regulation than differences in individual genes themselves, researchers from Yale, the University of Chicago, and the Hall Institute in Parkville, Victoria, Australia, argue in the 9 March 2006 issue of the journal Nature.

The scientists provide powerful new evidence for a 30-year-old theory, proposed in a classic paper from Mary-Claire King and Allan Wilson of Berkeley. That 1975 paper documented
