In extreme conditions, heat does not flow between materials. It bounces off. A new study supported by the U.S. National Science Foundation shows, for the first time, how heat moves — or rather, doesn't — between materials in a high-energy-density plasma state. The work is expected to provide a better understanding of inertial… Read more at nsf.gov
Why does the inner solar system not spin faster? The motion of a tiny number of charged particles may solve a long-standing mystery about thin gas disks rotating around young stars, according to a new study by Caltech researchers. These features, called accretion disks, last tens of millions of… Read more at nsf.gov
