IMPROVED SUPERCONDUCTIVITY IN MULTI-WALLED CARBON NANOTUBES, March 13
A group of researchers from several institutions in Japan has observed superconductivity - a phenomenon in which electrons flow with no resistance - in billionth-of-a-meter sized cylindrical carbon molecules known as "multi-walled carbon nanotubes." The nanotubes' ability to superconduct adds to their many intriguing electrical and physical characteristics. Moreover, it increases the likelihood that carbon nanotubes will one day drastically improve electronics, building materials, and many other products.

FREEZING MAGNETS WITH MAGNETS, March 14
A "spin liquid" is a very unique, dynamic material in which each spin - the tiny magnetic field carried by an electron - is not frozen into place, producing clearly defined magnetic regions. Instead, the spins are free to change orientation. Because of this, external magnetic fields applied to spin liquids may produce changes that even extreme temperatures and pressures cannot.

BROOKHAVEN SCIENTISTS WORKING TOWARD PRACTICAL HYDROGEN-STORAGE MATERIALS, March 15
Hydrogen-storage materials hold the promise of supporting many exciting new technologies, such as clean, efficient hydrogen fuel cells for automobiles. At the U.S. Department of Energy's Brookhaven National Laboratory, scientists are working toward this goal by studying the basic mechanisms that underlie reversible hydrogen storage in certain materials.
