Scientist refines cosmic clock to determine age of Milky Way

The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. Dauphas' method, which he reports in ...

Size matters: Friction, adhesion change on atomic level

Physicists have a pretty good idea of what to expect when friction and adhesion occur in the visible world. You jam on the brakes, for instance, and your tires and the highway interact to stop your car. You glue two pieces ...

New robots help patients walk, touch, feel
