Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

Rising sea levels 20,000 years ago, as the last ice age was beginning to wane, often are attributed in part to melting in West Antarctica. But in a new study led by University of Washington researchers, an ice core of 1,000 meters was used as a sort of dipstick to show that a key...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

...ed significantly. In the second, third, and fourth years of the pilot phase, the centers in aggregate reported 109, 217, and 348 structures, respectively. Now, halfway through the fifth year, they’ve surpassed a total of 1,000. Many of these structures are very different from previously known structures, s...

PANTHER Protein Classification System Database 5.0

...ions of fruit fly genes have beenavailable for two years as part of an ongoing collaboration withFlyBase. “The task of performing functional annotation of genomes ischallenging. Too often we rely simply on transitive annotation based ona BLAST match. The PANTHER system offers a much more sophisticatedsyste...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

... prenylation pathway ?that regulates Ras. Several years ago, Casey's laboratory was one of a handful to unravel how the prenylation pathway works. This accomplishment led pharmaceutical companies to test compounds that block another key player in the pathway, a protein called farnesyltransferase. Blocking...

Simple drug has the potential to save many lives threatened by malaria

...itory) in 103 children aged between 6 months and 5 years with severe malaria. They found the two treatments broadly comparable and suggest that rectal artemether could be used to treat severe malaria where qualified staff and equipment for intravenous therapy is not available. These are encouraging resul...

Scientists identify new model Of NK cell development

Scientists have believed for years that human NK cells are generated in bone marrow, but Michael Caligiuri, director of the OSU Comprehensive Cancer Center and the senior author of the study, says research in his laboratory shows that the precursors to NK cells are actually found in c...

New RNA polymerase discovered in plants

...cotyledon. "These two plants diverged 200 million years ago, and there is some speculation that this form of polymerase might extend twice as far back in evolution,' Pikaard said. Pikaard said that it is strange that so far this kind of polymerase has been found only in plants. "Why would plants only ha...

Boosting HIV screening can increase survival and is cost effective

Frequent HIV screening in moderate-to-high-risk populations could produce life expectancy gains at costs that compare favorably to many commonly employed screening intervent...

Since the hardware is the same, the difference between mice and humans must be at the software level--which determines h...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

Similar proteins involved in essential cellular functions are often similar across species. "This new result indicates that the way in which the most functionally important pr...

"I noticed this five years before in Panama, but it was at that moment in Peru 18 months ago that I realized why they do it: They're trying to get back to the tree, they're trying to not get lost in the understory of the forest," he said. Once they hit the forest floor, he add...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

Through sequence alignment with increasingly strict criteria, they identified 1,373 highly conserved non-coding element...
