Scientists have identified key genes responsible for a severe inflammatory disease that has spread along the old silk trading routes from the Far East to the edge of Europe.

To trap and hold tiny microparticles, engineers at Harvard have "put a ring on it," using a silicon-based circular resonator to confine particles stably for up to several minutes.

Specialized brain training targeted at the regions of a rat's brain that process sound reversed many aspects of normal, age-related cognitive decline and improved the health of the brain cells, according to a new study from researchers at University of California, San Francisco.

Scientists, practitioners and advocates from around the world today made a united call for global leaders to commit at least $US20 billion to the Global Fund to Fight AIDS, Tuberculosis and Malaria at its upcoming replenishment meeting in October.
