Researchers trace evolution of self-control

Human self-control evolved in our early ancestors, becoming particularly evident around 500,000 years ago when they developed the skills to make sophisticated tools, a new study suggests.

Physicists weigh in on the origin of heavy elements

A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of "this" stuff and not other stuff?

A chemical embrace from the perfect host

An industrial process that currently consumes vast amounts of energy in petrochemical plants around the globe could be replaced by an alternative process so efficient that it requires no heating or elevated pressure.

Mechanical forces shape bacterial biofilms' puzzling patterns

Belying their slimy natures, the sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Now, researchers at Princeton University have combined expertise in molecular biology, ...
