Seeing the breath of life: specially treated gases could soon bring a breakthrough in medical imaging
Article Abstract:
Researchers are studying the possibility of utilizing helium and xenon in magnetic resonance imaging (MRI) to provide more detailed scans of the lungs, brain, colon and other organs. The technique involves hyperpolarizing the gases to generate MRI signals that are about 100,000 times stronger per nucleus than those produced by water.

Clearing the air; common rocks may deliver cleaner power
Article Abstract:
Researchers at the Los Alamos National Laboratory are studying the feasibility of using common minerals to minimize the impact of carbon dioxide emissions on the atmosphere. They believe that such minerals can be made to react with carbon dioxide to create a harmless waste product.
