Mars Express observes aurorae on the Red Planet
Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks.   view more (2008-11-24)

New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA—a tiny gold beam whose 40 million vibrations per second are measured by hopping electrons—offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes (STM), perhaps paving the way for scientists to watch atoms... view more (2007-03-19)

Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers.   view more (2007-07-13)

UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the... view more (2007-06-01)

G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes... view more (2006-06-30)
