Getting ready for the 'big one,' researchers make most detailed survey ever of San Adreas Fault
Researchers have completed the most meticulous survey ever made of the San Andreas Fault, and they've found detailed features that nobody could have seen before. Michael Bevis, Ohio Eminent Scholar in geodynamics and professor of civil and environmental engineering and geodetic science at Ohio State University, unveiled the first images from the ambitious new survey Wednesday at the American Geophysical Union meeting in San Francisco.

Dietary intake of antioxidants associated with reduced risk of age-related macular degeneration
A diet with a high intake of beta carotene, vitamins C and E, and zinc is associated with a substantially reduced risk of age-related macular degeneration in elderly persons, according to a study in the December 28 issue of JAMA.

Bystanders become good samaritans when the stakes are high
A person is in trouble in a crowded place, but no-one steps over to help. The situation is called the bystander effect, and it appears that the more people watching, the less likely it is that anyone will respond. But new research shows that even when accompanied by another person, individuals are much more likely to intervene if the situation is dangerous or violent, and when they feel empathy for the victim.

Rutgers researchers scientifically link dancing ability to mate quality
Dance has long been recognized as a signal of courtship in many animal species, including humans. Better dancers presumably attract more mates, or a more desirable mate. What's seemingly obvious in everyday life, however, has not always been rigorously verified by science. Now, a study by Rutgers scientists for the first time links dancing ability to established measures of mate quality in humans.

Scripps marine research physiologist pioneer to receive lifetime achievement award

As Grid problem solving flows smoothly
Computational Fluid Dynamics, a technique that can be used to measure the flow of water around a ship's hull or the exhaust flow of a car engine, requires complex, processing-intensive software. It is therefore a key candidate to benefit from Grid computing, as the FlowGrid project proved.

Bullying in middle school may lead to increased substance abuse in high school
Over the past decade, parents, educators and policy makers have become increasingly concerned about verbal and physical harassment in schools and the subsequent effects of peer victimization on teens. A recent study by Julie C. Rusby and colleagues from the Oregon Research Institute, published in the November 2005 issue of The Journal of Early Adolescence by SAGE Publications, found significant associations between peer harassment of students in middle school and a variety of problem behaviors, such as alcohol abuse, once these students reach high school.

UQ researchers show traditional Chinese exercises can help combat diabetes
A pilot study for Australia's first clinical trial to evaluate the effectiveness of traditional Chinese exercises in preventing the growing problem of diabetes has produced startling results

Women who undergo reconstructive breast implantation frequently develop short-term complications

Male elephants woo females with precise chemistry
The exact chemical blend of a pheromone emitted by older male elephants in musth influences both a female elephant's interest in mating and how other surrounding elephants behave, a new study has found. Oregon and New Zealand researchers say the release of a specific proportion of two mirror images of the pheromone, frontalin, depends on whether the male elephant is mature enough and has reached a particular stage of its annual period of sexual activity.

Cell biologists applaud intelligent design ruling
Zena Werb, President of the American Society for Cell Biology, hailed the ruling Thursday by US District John Jones in 'Kitzmiller et al v. Dover Area School District' that teaching 'intelligent design' would violate the Constitutional separation of church and state. 'The ruling by Judge Jones preserves the notion that science classrooms are solely for the teaching of science,' said Werb. 'Yesterday was a great day for science education.'

Nearly a quarter of children are especially susceptible to respiratory illness if they are exposed to second-hand smoke
Children with a certain genetic makeup are at heightened risk of chest infections and other respiratory illnesses due to second-hand smoke exposure, according to researchers from the Keck School of Medicine of the University of Southern California.

How do boxers differ from poodles? Researchers collar genomes
As any dog lover knows, no two breeds are identical. Some dogs are perfect for sloppy kisses. Others make fierce guardians. Still others resemble tiny, fluffy toys. Now, two new studies by scientists at The Institute for Genomic Research (TIGR) and collaborators reveal the genomic differences beneath such canine characteristics.

Parents advised to rethink dummy use
A comprehensive review of scientific studies on the use of baby pacifiers (dummies) has found that they interfere with successful breastfeeding.

Microbes under Greenland Ice may be preview of what scientists find under Mars' surface
The presence of methane in Mars' atmosphere has led some scientists to propose that methane-producing microbes live under the surface. If that's true, UC Berkeley's Buford Price knows just where to look. His study of methane-producing Archaea at the base of Greenland's two-mile thick ice sheet indicates that about one microbe per cubic centimeter a few hundred meters underground could produce enough methane to maintain observed levels in the Martian atmosphere.

Personal fulfillment may motivate adolescents to be physically active
Adolescents are most likely to report personal fulfillment as the strongest motivation to be physically active. Personal fulfillment motivation should be considered when designing physical activity promotion programs for youth, according to a study in the December issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
