BUFFALO, N.Y.-- In the wake of the earthquake in Haiti, University at Buffalo geography students are participating in a global effort to enhance the international response and recovery effort by helping to assess damage, using images hosted by Google Earth and the Virtual Disaster Viewer, which shares imagery of disasters from various sources.

ANN ARBOR, Mich.-- A 9 cubic millimeter solar-powered sensor system developed at the University of Michigan is the smallest that can harvest energy from its surroundings to operate nearly perpetually.
The U-M system's processor, solar cells, and battery are all contained in its tiny frame, which measures 2.5 by 3.5 by 1 millimeters. It is 1,000 times smaller than comparable commercial counterparts.

Vesicular stomatitis virus, or VSV, has long been a model system for studying and understanding the life cycle of negative-strand RNA viruses, which include viruses that cause influenza, measles and rabies.
More importantly, research has shown that VSV has the potential to be genetically modified to serve as an anti-cancer agent, exercising high selectivity in killing cancer cells while sparing healthy cells, and as a potent vaccine against HIV.

A century after Amedeo Modigliani painted the Portrait of Maud Abrantes, the mystery behind the painting might be solved. Ofra Rimon, Director and Curator of the Hecht Museum at the University of Haifa, discovered that hidden in the painting is the portrait of another woman. "Modigliani was probably not happy with that painting and decided to paint over it in favor of a portrait of Maud," she claims.

Researchers in Chicago and London have developed a method for controlling the properties of magnets that could be used to improve the storage capacity of next-generation computer hard drives.
Magnets that can readily switch their polarity are widely used in the computer industry for data storage, but they present an engineering challenge: A magnet's polarity must be easily switched when writing data to memory, but be difficult to switch when storing or reading it.

KINGSTON, ON -- Treatment of prostate cancer using a very low dose of nitroglycerin may slow and even halt the progression of the disease without the severe side effects of current treatments, Queen's University researchers have discovered
The findings are the result of the first-ever clinical trial using nitroglycerin to treat prostate cancer.
The 24-month, Phase II study targeted 29 men with increasing levels of prostate-specific antigen (PSA) following prostate surgery or radiation. PSA levels are a key predictor of cancer progression.

MBL, WOODS HOLE, MA—The phrase "perk up your ears" made more sense last year after scientists discovered how the quietest sounds are amplified in the cochlea before being transmitted to the brain.

But in results published Feb. 5 in the journal Science, a Princeton-led team of scientists has observed electrons in a semiconductor on the brink of the metal-insulator transition for the first time. Caught in the act, the electrons formed complex patterns resembling those seen in turbulent fluids, confirming some long-held predictions and providing new insights into how semiconductors can be turned into magnets. The work also could lead to the production of smaller and more energy-efficient computers.
