The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.

Middle school children who have a television or computer in their room sleep less during the school year, watch more TV, play more computer games and surf the net more than their peers who don't – reveals joint research conducted by the University of Haifa and Jezreel Valley College.

The freezing of assets of the three Somalis residing in Sweden was not an infringement of international law. Those who criticize the action are undermining the legitimacy of UN sanctions, according to Fredrik Stenhammar, a doctoral candidate at the Department of Law, Stockholm University, in Sweden.

Intima-media thickness (IMT) of the carotid artery can easily be evaluated by non-invasive ultrasound technique. The technique is standardized, has a high reproducibility and allows monitoring over time. Intima-media thickness can also be measured in the brachial and femoral arteries. IMT should be measured preferably on the far wall. This is because IMT values from the near wall depend in part on gain settings and are less reliable. It is also possible to visualize plaques in the artery with ultrasound technique.

Los Angeles, London, New Delhi, Singapore, and Washington, DC – (August 29, 2008) It may cost money to improve the quality of nursing care through increases in staffing or work environment changes but those costs may be offset through improved patient outcomes and nurse retention, according to research in a Special Issue of Policy, Politics & Nursing Practice published by SAGE.

More than half of orphaned youth age 12 to 24 who head households in rural Rwanda meet criteria for depression, according to a report in the August issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

The pain of downsizing extends far beyond laid off workers and the people who depend on their paychecks, according to a new UCLA-University of Michigan, Ann Arbor study.

Even a single involuntary displacement has a lasting impact on a worker's inclination to volunteer and participate in a whole range of social and community groups and organizations, found the study, which appears in the September issue of the international scholarly journal Social Forces.

Male Jamaican anole lizards begin and end the day with displays of reptilian strength -- push-ups, head bobs and extensions of a colorful neck flap, or dewlap -- to defend their territory, according to a new study.

Whether driving on the highway or walking down the street, we pick up on both deliberate signals and unconscious cues to predict what other people are going to do and act accordingly. But robots have trouble following each other around, for example, when a leader turns a corner and disappears from sight. Researchers at UC Davis have come up with a control system that allows a robot to pick up on cues that the leader is about to turn, predict where it is going and follow it.

The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found.

But how hot is this "hotspot," and what's causing it?

In an effort to find out, Derek Schutt of Colorado State University and Ken Dueker of the University of Wyoming took the hotspot's temperature.

The scientists published results of their research, funded by the National Science Foundation (NSF)'s division of earth sciences, in the August, 2008, issue of the journal Geology.
