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.

RSV Vaccine in Pregnancy Not Associated With Increased Preterm Birth Risk, Study Finds

A new study has found that a vaccine against respiratory syncytial virus (RSV) administered during pregnancy was not associated with increased risks of preterm birth or other poor outcomes.

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.

Liver Cells Put a “Sleep Timer” On Immune Cells in Chronic Hepatitis B Infection

A team has discovered that cells in blood vessels in the liver start a “sleep timer” that switches off immune cells, and targeting this mechanism could be a starting point for immunotherapies.
