Exercise has a similar effect to antidepressants on depression. This has been shown by previous research. Now Astrid Bjørnebekk at Karolinska Institutet has explained how this can happen: exercise stimulates the production of new brain cells.
Analyses of a national sample of individuals with alcohol dependence (alcoholism) reveal five distinct subtypes of the disease, according to a new study by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).
Researchers studying links between an early sign of heart disease called coronary artery calcification and body fat have found that, paradoxically, more fat may have some advantages, at least for people – particularly women – who have type 1 diabetes. Cardiovascular complications, including heart disease, are a leading cause of death for people with diabetes, who tend to suffer cardiovascular disease decades earlier than non-diabetics.
Pioneering work to reduce the use of animals in scientific research — and ultimately remove them from laboratories altogether — has received a major boost at The University of Nottingham.
A complete cure from an HIV-infection is currently not available. At present, lifelong treatment regimes are required to block the outbreak of AIDS, and these treatments do not eliminate the integrated provirus from infected cells. But German scientists have developed an enzyme that specifically cuts out the viral genome and eradicates the virus from the host cell.
The U.S. Food and Drug Administration is warning consumers not to eat Veggie Booty snack food, marketed by Robert’s American Gourmet, due to possible contamination with Salmonella Wandsworth, bacteria that cause gastrointestinal illness.
NASA’s Mars rover Opportunity is scheduled to begin a descent down a rock-paved slope into the Red Planet’s massive Victoria Crater. This latest trek carries real risk for the long-lived robotic explorer, but NASA and the Mars Rover science team expect it to provide valuable science.
A NASA satellite has captured the first occurrence this summer of mysterious shiny polar clouds that form 50 miles above Earth’s surface. The first observations of these “night-shining” clouds by a satellite named “AIM” which means Aeronomy of Ice in the Mesosphere, occurred above 70 degrees north latitude on May 25. People on the ground began seeing the clouds on June 6 over Northern Europe.
“When I think of embryonic stem cells, I think of the number zero. How many clinical trials are there now involving embryonic stem cells? Zero. How many treatments use embryonic stem cells? Zero. How many people have ever been helped by ESCs? ZERO.”
Web searchers who evaluated identical search-engine results overwhelmingly favored Yahoo! and Google, providing evidence that branding matters as much on the Internet as off, according to a Penn State study.
