Following a rollover automobile accident, driver and passengers are usually unable to call for help. So, unless the accident occurs on a busy road, rescue is unlikely to arrive in time to save them. Writing in the International Journal of Intelligent Defence Support Systems, US researchers describe SAVE, which could solve that problem and reduce deaths on the roads.
OAK RIDGE, Tenn., Feb. 9, 2009 -- For the first time, farmers have data that tracks at the county level on-site and off-site energy use and carbon dioxide emissions associated with growing crops in the United States.
This information is vital for examining changes in cropland production and management techniques and could play an even bigger role as more land is devoted to bioenergy crops, said Oak Ridge National Laboratory's Tristram West, lead author of a paper published on line in the Journal of Environmental Quality.
Solid-state nuclear magnetic resonance, or SSNMR, is a valuable tool to image and analyze the chemical makeup of proteins and other biomolecules. But the imaging process is time-consuming and requires large amounts of costly isotope-labeled sample for study.
Overfishing on coral reefs isn't simply caused by too many people, according to a new report published in the February 10th issue of Current Biology, a Cell Press publication. Rather, the researchers found that the biomass of fish found on coral reefs in the western Indian Ocean depended mostly on the complexity of the reefs themselves and the socioeconomic status of the people living on the shores.

Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or – a surprising new study finds – float up from the sea floor.
The discovery, published online Feb. 8 in Nature Geoscience, connects life at the surface to events occurring at extreme depths and pressures.
The two worlds were long assumed to have little interaction.
CLEVELAND – A recent discovery at Case Western Reserve University may help keep food and drugs safer and fresher longer and electronic equipment dryer and more secure than ever before – all at a lower cost.
Scientists can easily explain the structural order that makes steel and aluminium out of molten metal. And they have discovered the molecular changes that take place as water turns to ice. But, despite the fact that glass blowers have been plying their trade since the first century BC, we have only just begun to understand what makes molten glass solid.
"Conventional wisdom – and conventional theory – tells us that when infection can potentially be spread to almost everyone in a community, such as for measles, a disease outbreak can never be contained using voluntary vaccination," says Chris Bauch and Ana Persic, researchers from the University of Guelph. "However, our work shows conventional wisdom may be wrong for diseases that are spread primarily through close contact, such as smallpox." Their findings appear in the open-access journal PLoS Computational Biology on February 6th.
Alcohol advertising and marketing may lead to underage drinking. A large systematic review of more than 13,000 people, published in the open access journal BMC Public Health, suggests that exposure to ads and product placements, even those supposedly not directed at young people, leads to increased alcohol consumption.
