Alzheimer's: Therapy for brain disease could target blood (December 31, 2010) -- The aggregated proteins strewn about the brain are the hallmark of one of the most common neurodegenerative disorders: Alzheimer's disease. But while these irregular, gunky proteins, called amyloid-beta, are believed to contribute to the deterioration of memory and cognitive ability in Alzheimer's patients, no one knows how they lead to these symptoms. New experiments show how amyloid-beta interacts with a clotting agent in the blood, increasing blood clots that are harder than usual to break down and starving neurons of their regular supply of oxygen. The research suggests that the effects of amyloid-beta on the blood vessels feeding the brain could be an important aspect of the havoc they wreak on the brain. ... > full story
New cognitive robotics lab tests theories of human thought (December 31, 2010) -- Researchers are exploring how human thought outwits brute force computing in the real world. Twenty programmable robots allow students to test the real-world performance of computer models that mimic human thought. ... > full story
Strict heart rate control provides no advantage over lenient approach, study finds (December 31, 2010) -- Strict heart rate control in atrial fibrillation patients is not beneficial over lenient control, according to new research. The antiplatelet drug clopidogrel, plus aspirin, might be considered to reduce the risk of major vascular events, including stroke in patients who are poor candidates for the anticoagulant drug warfarin. Catheter ablation is useful to maintain normal sinus rhythm in patients with atrial fibrillation. ... > full story
Lower levels of education are associated with increased risks of heart failure (December 31, 2010) -- Results from a large European study suggest that poorly educated people are more likely to be admitted to hospital with chronic heart failure than the better educated, even after differences in lifestyle have been taken into account. ... > full story
Consistent exercise associated with lower risk of colon cancer death (December 31, 2010) -- Consistent exercise is associated with a lower risk of dying from colon cancer, according to a new study. The study is among the first to show that physical activity can make the disease less deadly. ... > full story
Home health care could help sustain health care systems, study finds (December 31, 2010) -- Home health care technology may provide one important solution to global concerns about how to sustain health care systems threatened by rising costs and manpower shortages, but such a change faces multiple obstacles to adoption, according to a new study. ... > full story
What makes a face look alive? Study says it's in the eyes (December 31, 2010) -- The face of a doll is clearly not human; the face of a human clearly is. Telling the difference allows us to pay attention to living things, which are capable of interacting with us. But where is the line at which a face appears to be alive? A new study finds that a face has to be quite similar to a human face to appear alive, and that the cues are mainly in the eyes. ... > full story
Risk for alcoholism linked to risk for obesity (December 31, 2010) -- Addiction researchers have found that a risk for alcoholism also may put individuals at risk for obesity, and the association between a family history of alcoholism and obesity risk has become more pronounced in recent years. ... > full story
Expansion of HIV screening cost-effective in reducing spread of AIDS, study shows (December 31, 2010) -- An expanded US program of HIV screening and treatment could prevent as many as 212,000 new infections over the next 20 years and prove to be very cost-effective, according to a new study. ... > full story
George Clooney Effect? High-earning women want older, more attractive partners, research finds (December 31, 2010) -- Psychologists have found that George Clooney may be even luckier than previously thought. New research has discovered that as women become more financially independent, they want an older, more attractive male partner. ... > full story
Your genome in minutes: New technology could slash sequencing time (December 31, 2010) -- Scientists are developing technology that could ultimately sequence a person's genome in mere minutes, at a fraction of the cost of current commercial techniques. ... > full story
New test for major killer of lung transplant patients: High stem cell count after transplant predicts debilitating syndrome (December 31, 2010) -- A lung transplant can mean a new chance at life. But many who receive one develop a debilitating, fatal condition that causes scar tissue to build up in the lungs and chokes off the ability to breathe. Researchers hope a new diagnostic tool they developed to predict bronchiolitis obliterans syndrome will allow doctors to intervene earlier and, ultimately, to provide life-saving treatments. ... > full story
