The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) using a state-of-the-art protein crystallography beamline at the Advanced Light Source (ALS).
NEW YORK (November 24, 2009) -- The Wildlife Conservation Society (WCS) announced today a report revealing that the last remaining population of Siberian tigers has likely declined significantly due to the rising tide of poaching and habitat loss.
The first large black holes in the universe likely formed and grew deep inside gigantic, starlike cocoons that smothered their powerful x-ray radiation and prevented surrounding gases from being blown away, says a new study led by the University of Colorado at Boulder.
New Haven, Conn. -- The world's oceans are absorbing less carbon dioxide (CO2), a Yale geophysicist has found after pooling data taken over the past 50 years.
A community-based program aimed at reducing the burden of skin disease across remote communities in Australia's Northern Territory has been successful according to a study published November 24 in the open-access journal PLoS Neglected Tropical Diseases.
Chestnut Hill, Mass. (11/24/2009) -- New findings from an international team of researchers probing the nerve-insulating myelin sheath were bolstered by the work of Boston College biologists, who used x-rays to uncover how mutations affect the structure of myelin, a focal point of research in multiple sclerosis and other neurological disorders.
SALT LAKE CITY -- Researchers at Huntsman Cancer Institute, in collaboration with a worldwide group of physicians and scientists, have discovered a remarkable treatment for a rare, yet debilitating, skin condition.
Cambridge, Md. (November 24, 2009) -- New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions.
Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells.
BEER-SHEVA, ISRAEL November 24, 2009 -- Researchers at Ben-Gurion University of the Negev are developing a new device that detects cancerous skin tumors, including melanomas that aren't visible to the naked eye.
Even before they start school, many young girls worry that they are fat. But a new study suggests watching a movie starring a stereotypically thin and beautiful princess may not increase children's anxieties.
Many people who are overweight or obese develop insulin resistance and type 2 diabetes at some stage in their lives. A European research team has now discovered that obese people have large amounts of the molecule CXCL5, produced by certain cells in fatty tissue.
INDIANAPOLIS -- Involving family members of pediatric cancer and hematology patients in medical rounds benefits both the family and the medical team, according to a new Indiana University School of Medicine study.
CINCINNATI -- New research presents strong evidence that the "synergistic" effect of early-life exposure to both outdoor traffic-related pollution and indoor endotoxin causes more harm to developing lungs than one or the other exposure alone.
Researchers from the University of Michigan determined that only 663,000 of the approximately 3.9 million Americans with hepatitis C virus (HCV) infection received antiviral therapy between 2002 and 2007. Treatment rates appear to be declining, in part because only half of the patients know they are infected.
