Science panel endorses new non-animal test to see if chemicals will burn, corrode skin and eyes
For the first time, a new federally sponsored panel of scientists has endorsed the use of a non-animal test to determine -- for safety and regulatory purposes, and for labeling -- whether a chemical is likely to burn or corrode human skin.

Jet contrails to be significant climate factor by 2050
Contrails formed by jet planes passing through moist air are similar to cirrus clouds.

Swine vaccine developed by veterinary college researcher receives USDA approval for commercial use
A genetically altered vaccine developed by a researcher in the Virginia-Maryland Regional College of Veterinary Medicine has received the final green light from the United States Department of Agriculture (USDA) and is now being commercially marketed as an agent to prevent pneumonia in pigs.

New mechanism for regulating gene expression discovered
TRA-1, one of a family of proteins that turns genes on by binding directly to DNA, also binds to a specific region of mRNA during transcription, thus providing another mechanism by which cells can fine-tune protein production during embryo development.

Brain region used in face recognition is active in new object recognition
Researchers at Brown University and the Yale Medical School used functional magnetic resonance imaging (fMRI) to demonstrate that the area of the brain active in face recognition is also involved in recognizing new, non-face objects, according to a study in the June issue of Nature Neuroscience.

Protein essential for making steroids turns out to be a "molten globule"
UCSF scientists have identified part of the structure of steroidogenic acute regulatory protein (StAR).

Gladstone/UCSF team discovers interaction of two brain proteins may be key factor in development of Alzheimer's disease
A team of San Francisco scientists studying Alzheimer's disease has found the interaction of two brain proteins may be a critical factor in development of the debilitating disorder.

'Fishboys' - the new cowboys of a world dependent on water...and ceramics.
'Fishboys' herding schools of fish, in seas converted into giant fish ranches, could become more fact than fiction in the next century, according to Professor Robert Newnham speaking at the European Ceramics Society conference today.

Rats operate robotic arm via brain activity
Researchers at MCP Hahnemann University and Duke University have developed a method for recording brain signals onto electrode arrays in laboratory rats that enable the rats to control a robotic arm without any actual muscle movement.
