Graphene—carbon formed into sheets a single atom thick—now appears to be a promising base material for capturing hydrogen, according to recent research* at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania. The findings suggest stacks of graphene layers could potentially store hydrogen safely for use in fuel cells and other applications.

A team led by Princeton University scientists has tested Albert Einstein's theory of general relativity to see if it holds true at cosmic scales. And, after two years of analyzing astronomical data, the scientists have concluded that Einstein's theory, which describes the interplay between gravity, space and time, works as well in vast distances as in more local regions of space.

Dunes On Mars: How Sand Shifts Without Wind
It's a scientific mystery: How did dunes form on Mars when the wind doesn't seem strong enough to move the sand? Jasper Kok tells Guy Raz he may have the answer — it has to do with sand "bouncing" and "splashing" in a way that's different than what happens on Earth.
