Bobbing birds do it for a reason
Pronounced head-bobbing behavior during walking is a characteristic of diverse species of birds, but how this behavior benefits the birds and under what circumstances it proves useful have remained uncertain. Researchers this week report findings that strongly suggest that for some birds head bobbing is critical for the stabilization of their visual world, despite the motion of their bodies, and...The reason why antiviral therapy can't annihilate HIV infection, and what to do about it
Antiviral therapy has been used to suppress HIV replication and has dramatically improved the clinical course of disease in affected patients. But the existence of viral reservoirs precludes the complete elimination of HIV from treated patients. In a new study appearing on November 1 in The Journal of Clinical Investigation, Tae-Wook Chun and colleagues from the NIH offer new insight into the er...A reason why video games are hard to give up
Kids and adults will stay glued to video games this holiday season because the fun of playing actually is rooted in fulfilling their basic psychological needs. Psychologists at the University of Rochester, in collaboration with Immersyve, Inc., a virtual environment think tank, asked 1,000 gamers what motivates them to keep playing. The results published in the journal Motivation and Emoti...Leading reason for corneal transplants comes into focus
Guided by families with an unusual number of cases, scientists at Johns Hopkins have discovered the genetic origins of at least one form of Fuchs corneal dystrophy, FCD, the leading reason for corneal transplantation in the United States. In one form or another, FCD's trademark deterioration of the cells covering the clear, outermost lens of the eye affects more than 4 percent of the popul...Seven good reasons to approve the Institutes for Discovery

A recent study by researchers in the Institute of Preventive Medicine in Copenhagen suggests that drinking wine occasionally may be beneficial in countering dementia and Alzheimer's disease. Scientists, who found// that people who drank wine weekly or monthly were more than two times less likely to develop dementia, said that the findings are important because there may be substances in wine whic...More compelling reasons to lower blood pressure
A recent study by British researchers who analyzed 61 previous studies of blood pressure and cardiovascular disease, which together included 1 million people, found that lowering blood pressure, regardless of age and even if readings are in the normal range, could// have significant pay off in terms of reducing risk of strokes and heart attacks. The study which included a 13 year follo...Likely reason which makes analgesics work against Alzheimer's
Pain killers like ibuprofen or naproxen have long been known to help people protect themselves against Alzheimer's disease. Now, researchers from the University of California have found a possible reason as to why this might be so. These scientists had previously developed a marker molecule called FDDNP that was used to detect the presence of plaque. Plaque is a protein deposit in the brain that...
