Evolution of life on Earth may hold key to finding life in outer space

...the structure and function of all living cells and viruses and play a role in immune response. Fox and his group are examining the various components of the ribosome machinery trying to learn what parts came first and what was added later. "Since many of the components of the ribosome are shared by all orga...

Researchers report breakthrough against world’s deadliest viruses

Virus uses tiny RNA to evade the immune system

...y of California, San Francisco. Ganem studies how viruses infect people and cause disease. When scientists found that RNA interference appeared to be a basic and widespread gene regulatory mechanism, "it became clear that such a fundamental pathway could of course be pirated by a virus," said postdoctoral f...

UCLA scientists reveal how Nipah virus infects cells

... equivalent to the Ebola virus. To infect a cell, viruses must bind to a viral-specific receptor on the cell's surface in order to penetrate it. Lee's team identified a cell receptor called Ephrin-B2 as the key used by the Nipah virus to unlock the cells. Located on brain cells and cells lining the blood v...

Scavenger cells could be key to treating HIV-related dementia

"We agree there are different strains that populate different regions of the brain," said Francisco Gonzalez-Scarano, M.D., chairman of the University of Pennsylvania neurology department....

New discovery blurs distinction between human cells and those of bacteria

Since the 1940s, scientists have been trying to understand how the DNA in plants and some animals can be damaged by UV light, and then ?seemingly ?repaired by visible light. In the 1960s, ...
