Howard Hughes Medical Institute (HHMI) researchers and their colleagues have produced vast libraries of short segments of ribonucleic acid (RNA) that can be used to turn off individual human and mouse genes to study their function.

Odorants enhance survival of olfactory neurons
Research reveals olfactory sensory neurons exhibit activity-dependent survival, which may be critical for animals to retain responsiveness to odorants.

Soft drinks not linked to decreased calcium intake
A new study by researchers at the Center for Food and Nutrition Policy (CFNP) at Virginia Tech published in the Journal of the American College of Nutrition found that calcium intake among U.S. adolescents although inadequate, has remained a constant since the 1970s and does not appear to be linked to soft drink consumption.

Workplace drinking and gender harassment linked
A new Cornell University study shows that when alcohol consumption in and around the workplace increases, so does the risk of sexual harassment to women workers.

Southern Californians commonly misinformed about beach water quality, study finds
Scientists at The Henry Samueli School of Engineering at UC Irvine have found serious flaws in the methods used for warning Southern Californians about the quality of coastal water.

Myosin mutant points to human origins
In an effort to find the remaining genes that govern myosin--the major contractile protein that makes up muscle tissue--researchers at the University of Pennsylvania School of Medicine have made a discovery that may be central to answering key questions about human evolution.

The NYU Child Study Center and The Bear Stearns Charitable Foundation today announced that they have embarked on the second phase of their ongoing educational campaign aimed at raising awareness of the potential emotional impact of 9/11 and its aftermath on children.

The human brain and comparative judgments
A new study reveals significant information about how the brain interprets spatial and nonspatial sensory information to make comparative judgments about quantities such as number, size, and luminance.

Soya-powered planes
American biochemists say aircraft fuel based on soya oil is just the thing to give commercial aviation a greener future.

The puzzling spiral troughs that emanate from Mars' polar ice caps have been called the most enigmatic landforms in the solar system.

Land cover changes affect US summer climate
While climate may be impacted by carbon dioxide emissions, aerosols and other factors, a new study offers further evidence land surface changes may also play a significant role.

SMART-1 mission update
ESA's SMART-1 spacecraft has just made its 250th orbit, in good health and with all functions performing nominally.
