In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.
The key lies in a virus' RNA -- a long molecular chain often used to make proteins -- and how it regulates an enzyme called protein kinase R (PKR), acco... Read More
What gets the sea all riled up? Winds and tides do, certainly, but scientists have long wondered how the movement of fish and other organisms — even tiny ones, like zooplankton — might contribute to ocean mixing.

Infectious-disease specialists at UT Southwestern Medical Center have demonstrated that a cannibalistic process in cells plays a key role in limiting Salmonella infection.
Salmonella, the causative agent of salmonellosis, causes many of the intestinal infections and food-related illnesses rep... Read More
A new oral vaccine against sylvatic plague is showing significant promise in the laboratory as a way to protect prairie dogs and may eventually protect endangered black-footed ferrets who now get the disease by eating infected prairie dogs, according to results by a USGS researcher at the USGS N...
