A new study, led by researchers at Washington University School of Medicine in St. Louis, takes a deep dive into inherited cancer mutations measured in a healthy blood sample and reports how those mutations might take a toll on the body's cells starting at birth, perhaps predisposing a person to develop cancers at various stages of life.

In a mouse study they describe a brain pathway that starts with neurons (labeled in green, above) that sense inflammation signals, and the researchers were able to treat the loss of motivation by blocking this pathway.

The answer to one of humanity's biggest questions is complicated by a basic reality: If there is life on other worlds, it may not look familiar. A study in Nature Communications proposes a new way to search for life using tell-tale patterns of energy.

New calculations by researchers at Washington University in St. Louis suggest that the planet's outer crust may be constantly churning, an unexpected phenomenon called convection that could help explain many of the volcanoes and other features of the Venusian landscape.

The researchers identified a protein in cells that spurs the release of infection-fighting molecules. The protein, whose role in the immune system had not previously been suspected, provides a potential target for therapies that could prevent overreactive immune responses that are at the root of several debilitating illnesses.
