AUSTIN, Texas  Researchers at The University of Texas at Austin have devised a new method for enriching a group of the world's most expensive chemical commodities, stable isotopes, which are vital to medical imaging and nuclear power, as reported this week in the journal Nature Physics. For many isotopes, the new method is cheaper than existing methods. For others, it is more environmentally friendly.

How Mark Raizen and his lab -- and some borrowed ideas -- got atoms under control

June 14, 2010

Atom Stopper: In his quest to control atoms to a greater and greater degree, Professor Mark Raizen has borrowed ideas from chemistry, electromechanics and plasma physics. His journey demonstrates scientific creativity and the parts that serendipity and intuition play in discovery and that ideas can come from unexpected sources and arrive at unlikely times and places. It started in 2005 when Raizen took up the idea of controlling atoms.

Physicists Prove Einstein Wrong with Observation of Instantaneous Velocity in Brownian Particles

May 20, 2010

A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.
