Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data indicated positive detections.

Creating electricity with caged atoms

Posted: 22 Sep 2013 12:51 PM PDT

Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists have created a material which has extremely strong thermoelectric properties. It can be used to turn waste heat into electricity.

Formation of unusual ring of radiation around Earth explained

Posted: 22 Sep 2013 12:51 PM PDT

Since the discovery of the Van Allen radiation belts, scientists believed these belts consisted of two rings of highly charged particles. In February, scientists reported the discovery of a previously unknown third radiation ring -- a narrow ring that briefly circled the Earth for a month. Space scientists have successfully modeled and explained the unprecedented behavior of this third ring, and show that its energetic particles are driven by very different physics than the others.
