UCLA AIDS Institute researchers successfully removed CCR5 -- a cell receptor to which HIV-1 binds for infection but which the human body does not need -- from human cells. Individuals who naturally lack the CCR5 receptor have been found to be essentially resistant to HIV.

Dark matter, for more than 70 years as mysterious and unknowable a subject to science as the legendary island of Atlantis has been to history, is bringing 140 scientists from the U.S., Europe and Asia to the Marriott Hotel in Marina del Rey for the ninth UCLA Symposium on Sources and Detection of Dark Matter and Dark Energy in the Universe. The three-day conference runs through Friday, Feb.

New research using magnetic resonance imaging (MRI) shows that childhood stress such as abuse or emotional neglect, in particular when combined with genetic factors, can result in structural brain changes, rendering these people more vulnerable to developing depression.

CORAL GABLES, FL (February 25, 2010)----A new study by researchers from the University of Miami shows that maternal sensitivity may influence language development among children who go on to develop autism. Although parenting styles are not considered as a cause for autism, this report examines how early parenting can promote resiliency in this population.

WASHINGTON, Feb. 24 -- As part of LaserFest, the year-long celebration of the 50th anniversary of the first working laser, the Optical Society (OSA) and the American Physical Society (APS) sponsored a special day-long seminar on the birth, growth and future developments in laser science and technology at the 2010 American Association for the Advancement of Science (AAAS) annual meeting.

Bacteria in ocean sediments appear to string together nanowires to connect complementary but spatially separated chemical processes, according to a new study. The finding is the first example of a natural electrical circuit bridging a macroscopic gap, in this case more than a centimeter across, to mediate a biogeochemical process on either side.
