Redesigned Protein Accelerates Blood ClottingResearchers have made several, subtle changes in the structure of a key protein, dramatically increasing its ability to drive blood clotting, according to a new study. The findings have profound implications for the treatment of hemophilia, the inherited blood disorder that causes easy or excessive bleeding in 30,000 Americans.Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am College Students Find Comfort In Their Pets During Hard TimesA new study suggests that college students may handle stressful situations better if they have a pet. Research has already shown that pets can improve the quality of life for people who are aging or those who are chronically ill. But researchers have recently found that many college students may also benefit from owning a cat or a dog.Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am Chink Found In Armor Of Viral 'Tummy Bug'Researchers have moved a step closer to identifying a broad spectrum treatment for the dreaded 'viral tummy bug' or rotavirus.Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am Bioreactors Might Solve Blood-platelet Supply ProblemsIt might be possible to grow human blood platelets in the laboratory for transfusion, according to a new study. The findings might help end the tight supply of these critical blood components. Platelets are needed by certain cancer patients, bone marrow transplant patients, those needing massive blood transfusions and people with aplastic anemia. But concentrates from donors are expensive and up to 40 percent must be discarded.Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am We Are Better Able To Detect Racial Tension In Members Of Our Racial GroupIs it more difficult for members of different races to understand each others' emotions and intentions? A new study in Psychological Science reveals that we are better able to detect anxiety in members of our own racial group than in people of different racial backgrounds. The authors suggest that "race-matched observers appeared to draw upon subtle nonverbal indicators of intergroup anxiety that were undetectable to race-mismatched observers."Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am Biologists Learn Structure, Mechanism Of Powerful 'Molecular Motor' In VirusResearchers have discovered the atomic structure of a powerful "molecular motor" that packages DNA into the head segment of some viruses during their assembly, an essential step in their ability to multiply and infect new host organisms.Source: ScienceDaily: Latest Science News | 29 Dec 2008 | 1:00 am Common Treatment For Chronic Prostatitis Fails To Reduce Symptoms, Study ShowsAlfuzosin, a drug commonly prescribed for men with chronic prostatitis, a painful disorder of the prostate and surrounding pelvic area, failed to significantly reduce symptoms in recently diagnosed men who had not been previously treated with this drug, according to a clinical trial sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases.Source: ScienceDaily: Latest Science News | 28 Dec 2008 | 7:00 pm Brain Starvation As We Age Appears To Trigger Alzheimer's: Improving Blood Flow To Brain Is Preventive StrategyA slow, chronic starvation of the brain as we age appears to be a major trigger of a biochemical process that causes some forms of Alzheimer's disease. A new study has found when the brain doesn't get enough sugar glucose -- as when cardiovascular disease restricts blood flow to the brain -- a process is launched that produces the sticky clumps of protein that appear to be a cause of Alzheimer's.Source: ScienceDaily: Latest Science News | 28 Dec 2008 | 7:00 pm Honeybees As Plant 'Bodyguards'Honeybees are important to plants for reasons that go beyond pollination, according to a new study in Current Biology. The insects' buzz also defends plants against the caterpillars that would otherwise munch on them undisturbed.Source: ScienceDaily: Latest Science News | 28 Dec 2008 | 7:00 pm NASA Study Links Severe Storm Increases, Global WarmingThe frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory.Source: ScienceDaily: Latest Science News | 28 Dec 2008 | 7:00 pm Malaysia uses satellite to fight illegal logging: report (AFP)
