LETTING THE SPIN LOOSE, July 12
A team of scientists at the Weizmann Institute of Science has recently demonstrated conclusively that, in very specific circumstances, spin can become separated from charge and progress independently down a wire.
Two properties of an electron - its spin and its charge - are generally thought to be inseparable, intrinsic characteristics, no more given to sudden changes or going off on their own than say, the fur on a cat or the paint on a bicycle. But a team of scientists at the Weizmann Institute of Science has recently demonstrated conclusively that, in very specific circumstances, spin can become separated from charge and progress independently down a wire. Their findings appeared in a recent issue of Science.

METALS TAKE A WALK, July 12
Scientists in the Organic Chemistry Department of the Weizmann Institute of Science have caught a glimpse of platinum-based complexes 'walking' a path to their destinations
Do metal complexes casually stroll around certain molecules prior to chemical reactions? Scientists in the Organic Chemistry Department of the Weizmann Institute of Science have caught a glimpse of platinum-based complexes "walking" a path to their destinations.

SUPERCOMPUTER INSTALLED AT RIT AMONG THE WORLD'S FASTEST, July 12
One of the fastest supercomputers in the world and the first ever designed specifically to study the evolution of star clusters and galaxies is now in operation at Rochester Institute of Technology.
The new computer, built by David Merritt, professor of physics in RIT's College of Science, uses a novel architecture to reach speeds much higher than that of standard supercomputers of comparable size.
