Forced evolution: Can we mutate viruses to death? (Deem; 11/19/08, Press Release)It sounds like a science fiction movie: A killer contagion threatensEarth, but scientists save the day with a designer drug that forces thevirus to mutate itself out of existence. The killer disease? Stillfictitious. The drug? It could become a reality, thanks to a new studyby Rice University bioengineers.
How Random Disorder Destroys Superfluidity (Hulet; 11/20/08)Materials, no matter how pure they may be or how carefully they are prepared, inevitably have some random disorder. This disorder can be caused by crystal defects, impurities, or anything that changes the landscape of how electrons move about in the material. Many years ago, P.W. Anderson from Princeton University suggested that with enough disorder, an electrical conductor can be transformed to an insulator due to localization of the electrons. Disorder can also induce an otherwise superconducting material to become insulating, withe implications for important classes of superconductors, such as those made of thin films or small grains.
Rice physicists play role in new discovery from Fermilab's DZero experiment (Corcoran; 7/31/08, Press Release)Physicists from the DZero collaboration at Fermi National AcceleratorLaboratory in Batavia, Ill., this week announced the observation of akey pairing of subatomic particles called "Z bosons."

Microscopic Views of Gold Nanorods (Hafner; 9/6/07, Journal Physical Chemistry B)Very small gold particles lack the element’s familiar yellow luster. At a size scale of 10’s of nanometers, their optical properties are dominated by an effect called localized surface plasmon resonance (LSPR), which can be thought of as a resonance in the oscillation of the gold particle’s free electrons due to excitation by light. It has long been known that the LSPR of spherical gold particles peaks in the green.
