Cell Receptors in Dairy Cows a Prime Target for Influenza Infection

As highly pathogenic avian influenza has spread in dairy herds across the U.S., the virus is being detected in raw milk. A new study by a broad team of researchers at Iowa State University’s College of Veterinary Medicine helps explain why.

Most Salmonella Illnesses From Chicken Caused by Just a Few Products

A new study from the University of Illinois Urbana-Champaign shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts.

Brain Inflammation Study Reveals Pathways To Combat Muscle Fatigue in Long COVID and Alzheimer's

Researchers have found that brain inflammation results in the release of a protein that travels to the muscles resulting in fatigue. Targeting this protein could offer new hope for treating muscle pain associated with long COVID and Alzheimer's.

Severe COVID-19 Infections Foreshadow Severe Reinfections

Using health data from almost 213,000 Americans who experienced reinfections, researchers have found severe infections from the virus that causes COVID-19 tend to foreshadow similar severity of infection the next time a person contracts the disease.

Nearly Half of Cancer Cases Are Linked to Modifiable Risk Factors, Study Finds

A new study has found that 40% of cancer cases, and nearly 50% of all cancer deaths, are linked to “modifiable risk factors” such as cigarette smoking, excess body weight and alcohol consumption.

A Single “Kiss” From a Parasite Alters Human Host Cell Metabolism

Using a novel imaging technique, researchers have described how a parasite “kisses” the surface of host cells before infection and how this affects host cell metabolism.
