UVa Physics professor Cass Sackett is testing gravity and quantum mechanics in space using the Cold Atom Laboratory (CAL), a device aboard the International Space Station.  His work is described in the current edition of UVa Today:

"Using lasers and magnets to control atoms in a vacuum chamber, the cooler-sized lab allows Sackett and an international team of colleagues to do in space (remotely, from Earth) what can’t be done on the Blue Planet – that is, conduct sustained experiments into how matter at the most fundamental level operates in “microgravity” conditions under ultra-cold temperatures. That can’t be done so well from Earth because the strong gravity of our planet affects the motions of atoms, the subject of interest in CAL experiments."
