In 2011, NASA will launch two spacecraft that will orbit the Earth and sample the
harsh radiation belt environment. The Radiation Belt Storm Probes Mission will
provide scientists with the information they need to make predications about changes
in this critical region of space.

Biodesign Institute scientist John Chaput and his research team have
made the first self-assembled nanostructures composed entirely of
glycerol nucleic acid -- a synthetic analog of DNA. The nanostructures
contain additional properties not found in natural DNA, including the
ability to form mirror image structures. The ability to make mirror
image structures opens up new possibilities for nanotechnology.
