Detecting the presence of hazardous lead paint could become as simple as pressing a piece of paper against a wall and noting a color change.

Scientists at the University of Illinois at Urbana-Champaign have developed a highly sensitive and selective biosensor that functions in much the same fashion as a strip of litmus paper. The researchers report their discovery in a paper that has been accepted for publication in the Journal of the American Chemical Society, and posted on its Web

Findings may aid the development of drugs to treat thyroid disorders

Structural analysis has revealed for the first time how a key messenger in the body’s chemical communication system hooks up with one of the proteins that delivers it to sites of action in the body.

Using X-ray crystallography, scientists from Imperial College London and the University of Hawaii have identified the location of four binding sites on human serum albumin (HSA), the principal protein in bl

90 % of all large fish including tuna, marlin, swordfish, sharks, cod and halibut are gone – leading scientists say need to attempt restoration on a global scale is urgent

The cover story of the May 15th issue of the international journal Nature reveals that we have only 10% of all large fish– both open ocean species including tuna, swordfish, marlin and the large groundfish such as cod, halibut, skates and flounder– left in the sea. Most strikingly, the study shows that industrial

Mine-infested land can now be rendered safe by a new tractor that crushes unexploded bombs.

Unexploded anti-personnel landmines litter the border between Croatia and what was once Yugoslavia. The mine-infested area spans more or less half of the country and roughly 1,700 km2 of minefields are left to clear.

EUREKA’s first foray into anti-personnel landmine technology, the ORACLE project has developed a rugged tractor for clearing mines and unexploded shells from agricu

Taken from a microbe that thrives in the depths of a Yellowstone National Park hot springs pool, a newly discovered enzyme may be the key to transforming industrial bleaching from environmentally problematic to environmentally green.

Chemical engineer Vicki Thompson and biologists William Apel and Kastli Schaller from the U.S. Department of Energy’s Idaho National Engineering and Environmental Laboratory discovered that the catalase enzyme from a Thermus brockianus microbe flourishes i

Brief activation of signaling protein stimulates hair follicle growth phase

University of Michigan graduate student David Van Mater knew something strange was going on when he noticed stubble on the shaved skin of experimental mice in his laboratory. Instead of the tumors he had originally expected to see, the mice were growing hair.

Van Mater had stumbled on the discovery that beta-catenin (“bay-tuh-kuh-TEEN-in”), a signaling protein involved in embryonic development and se
