A new study suggests that chimpanzee subspecies may be more genetically variable than humans and also more closely related to each other.

Recipients of well-matched kidneys received locally require less long-term care
A study of thousands of kidney transplants suggests that the long-term cost of caring for patients could drop dramatically if more people received locally allocated kidneys that closely resembled their own organs.

The same rocket fuel that helps power the Space Shuttle as it thunders into orbit will now be taking on a new -- perhaps surprising -- role, with the potential to benefit millions of people worldwide.

Schools nationwide to test novel teaching method that redefines what it means to be smart
Yale scientists have received a $3 million National Science Foundation (NSF) grant to test triarchic instruction, a teaching method that focuses on children's creative and practical strengths, rather than their academic skills.

Revolutionary genomics project launched
Recognizing the profound significance of recent advancements in gene studies, the University of California, Davis, has launched a new genomics initiative that will unite scientists from across the campus in better understanding the actions of genes in growth, health, disease and behavior.

Shedding light on the origin of primate color vision
Researchers at the University of Chicago have found evidence that trichromatic or full color vision originated in prosimians, a group of lemurs, Bush Babies and pottos rather than in higher primates, pushing the origin of primate color vision back roughly 20 million years.

Experts will convene at Purdue to discuss information security
As the Y2K problems fade into the new year, computer analysts will face even more complex issues surrounding information security, Purdue University computer security expert Gene Spafford says.

California's environment threatened by global warming
A new two-year study by California's leading ecological scientists concludes that climate change poses a range of serious challenges for the state's environment and economy.

Clemson forum may help decide design of future space suits
A Clemson University forum may help decide the design of space suits used for future exploration on missions to Mars.

Medical scientists to begin clinical trials of promising cancer therapy
Scientists at the University of North Carolina at Chapel Hill are beginning phase one clinical trials, also known as safety trials, of a promising new way of treating certain cancers.

Wake Forest researchers ask: Can ginkgo prevent memory loss?
Researchers at Wake Forest University School of Medicine will test whether an extract from the leaves of the ginkgo tree can slow memory loss in older adults.

Cerebral cortex cells may pulse electrical rhythm through the brain
Brown University researchers have shown that some nerve cells in the cerebral cortex use electrical connections to communicate.

Protein component apparently plays key role in muscle elasticity
A pair of hydrogen bonds in the protein titin appears to be a key component allowing muscle to stretch and return to normal by regulating the ability of the protein to unfold one section at a time when stressed, researchers say.

Sounds of race cars reveal engine performance, racing strategy
The sound of a race car as it rounds the track can reveal engine performance, driver techniques and the racing team's strategy.
