Researchers investigate importance of STAT1 phosphorylation in NK cells

Since its discovery in the early 1990s, the protein STAT1 (Signal Transducer and Activator of Transcription 1) has been found to be central in passing signals across immune cells, ensuring that our bodies react quickly and appropriately to threats from viruses or other pathogens.

Scientists determine new strategy to estimate total viral diversity in mammals

EcoHealth Alliance, a nonprofit organization that focuses on local conservation and global health issues, and the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health announced a new strategy to identify the total number of wildlife viruses that could potentially cause emerging disease outbreaks that threaten both public and wildlife health.

Promiscuity in mice is matter of free choice

We know from earlier studies that mice can derive genetic benefits when females mate with multiple males, but until recently, the conditions under which females will voluntarily mate with multiple males were not clear. Kerstin Thonhauser and her colleagues from the Konrad Lorenz Institute of Ethology of the Vetmeduni Vienna conducted a series of experiments in which female wild-derived house mice (Mus musculus) could mate freely with one or two males while not in danger of sexual coercion by a male.

Barber pole worm genome provides essential platform to understand drug resistance in worms

Researchers have identified five enzymes that are essential to the survival of a parasitic worm that infects livestock worldwide and is a great threat to global food security. Two of these proteins are already being studied as potential drug targets against other pathogens.

Study reveals cancer in humans linked with high amounts of proteins responsible for cells division

Cancer in humans is frequently associated with unusually high amounts of one or more proteins responsible for controlling the rate at which cells divide. As an example, excessive amounts of the cyclin-dependent kinase CDK6 are often found in types of cancer such as lymphoma.

Researchers find antibodies specific to MERS-CoV in dromedary camels

Researchers searching for signs of Middle East respiratory syndrome coronavirus in livestock animals have found antibodies specific to the new virus in dromedary camels. The research, published in The Lancet Infectious Diseases, suggests that these animals have encountered MERS-CoV, or a closely related virus, and may be one reservoir of the virus that is causing MERS in humans.

FDA publishes new regulation defining "gluten-free" for food labeling to protect people with celiac disease

The U.S. Food and Drug Administration today published a new regulation defining the term "gluten-free" for voluntary food labeling. This will provide a uniform standard definition to help the up to 3 million Americans who have celiac disease, an autoimmune digestive condition that can be effectively managed only by eating a gluten free diet.
