Supercomputers to focus brains on AIDS dilemma

...04 Proceedings of the National Academy of Sciences reports on how the molecular dynamics simulations of the McCammon group dovetailed with Merck research, helping the company's scientists make sense of puzzling data of their own: seemingly similar inhibitors were binding to different parts of the enzyme's ac...

Oldest cranial, dental and postcranial fossils of early modern European humans confirmed

...e Mladec samples date to around 31,000 years ago," reports Eva Maria Wild from the VERA (Vienna Environmental Research Accelerator) Laboratory at University of Vienna, where the radiocarbon dating has been performed. This is the oldest assemblage of modern humans in Europe which retains many portions of the ...

Gene keeps neural cells on correct developmental path

...o liver, muscle, and other tissues. The new study reports that REST uses a different temporary off mechanism to direct neuronal development. "This study shows that there is more than one way to keep a REST-regulated gene repressed," said Michael G. Rosenfeld, an HHMI investigator at University of California...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

...al Society’s journal Nano Letters. Lindsay’s team reports achieving an experimental result that physicists have been trying to detect for a long time: negative differential resistance in a single molecule attached to electrodes. The specifically designed molecule, a hepta-aniline oglimer, belongs to a grou...

AIDS Public Awareness Campaign Expands Following Report Of Rapidly Progressive HIV

...auses AIDS. Dr. Novello said, "In light of recent reports of a drug-resistant, rapidly progressive strain of HIV in New York City, we must continue to reinforce critical HIV prevention messages to help New Yorkers protect themselves. Although, at this point, this is the only case of its kind we know of, it ...

Future diabetes drugs may target new protein interaction

But at this point, knowing for sure whether sirtuin1 helps extend lifespan (an organism issue) or is merely involved in cellular aging (a cell-by-cell...

'Smart drug' targets deadly brain cancer

...y the North Central Cancer Treatment Group (NCCTG) reports that a new "smart" drug treatment for an incurable form of recurrent brain cancer slowed tumor growth in more than one-third of the 65 adult patients who tried it. The same research team also developed a screening technique to help predict which pati...

Researchers find gene that may be at root of potato blight

...to global food security," Kamoun said. "Disturbing reports predict that potato late blight could cause food shortages and hunger in several parts of the world." He added that the spread of P. infestans may hit developing nations particularly hard, as potatoes are a staple crop in many of these countries. P...

Butterfly migration could be largest known

... times," Shapiro said. Shapiro said he is getting reports of "billions" of butterflies around Trona, near Death Valley, and in the San Fernando Valley. More waves of butterflies are likely to appear in central California over the next few weeks as the insects take wing. Painted lady butterflies, known by t...

Primates on the brink

...tological Society in Turin, Italy, follows similar reports in 2000 and 2002. Fifteen of the primates on the new list, including the Sumatran orangutan of Indonesia and the northern muriqui of Brazil, are "three-time losers" for having appeared on all three lists. Seven are new additions to the 2004-2006 list...

Shark attack worries? Driving to the beach is more deadly

...the human shape as a prey item. Sometimes you hear reports of surfers having their boards hit by a shark, and it's probably because the board resembles the shape of a seal, which is a prime food source for sharks." McEachran says some common sense can go a long way in avoiding contact with sharks. "Sharks ...
