The human brain excels at using past experiences to make predictions about the future. However, the world around us is constantly changing, and new events often violate our logical expectations. Researchers have discovered that unexpected stimuli enhanced an early and a late electrical potential in the hippocampus and the late signal was associated with a [...]

A new non-neurotoxic treatment for head lice has been found to have an average of 91.2 percent treatment success rate after one week, and to be safe in humans from six months of age and up.

Astronomers have taken a dramatic new image of NGC 346, the brightest star-forming region in our neighboring galaxy, the Small Magellanic Cloud, 210,000 light-years away towards the constellation of Tucana (the Toucan). The light, wind and heat given off by massive stars have dispersed the glowing gas within and around this star cluster, forming a [...]

Children can have strokes, and the strokes can recur, usually within a month, according to pediatric researchers. Unfortunately, the strokes often go unrecognized the first time, and the child does not receive treatment before the recurrence.
When NASA’s satellite operators need accurate, real-time space-weather information, they turn to the Community Coordinated Modeling Center (CCMC) of the Space Weather Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Md. The CCMC’s newest and most advanced space-weather science tool is the Integrated Space Weather Analysis system.

Single men and unhappily married men may face a higher risk of fatal stroke in later decades compared to happily married men. The data were taken from interviews done in Israel in the 1960s and follow-up through 1997. It did not include women.

Astrophysicists have determined that a massive planet outside our Solar System is being distorted and destroyed by its host star — a finding that helps explain the unexpectedly large size of the planet, WASP-12b. It’s a discovery that not only explains what’s happening to WASP-12b; it also means scientists have a one-of-a-kind opportunity to observe [...]

Researchers found that a modified version of cardiac rehabilitation was effective at reducing some symptoms of stroke in just six weeks following a transient ischemic attack (TIA) often referred to as “mini strokes.” No post-TIA regimen exists to help prevent future strokes — something that researchers say needs to change.

A laser technique best known for its use to remove unwanted tattoos from the skin is finding a second life in preserving great sculptures, paintings and other works of art. The technique, called laser ablation, involves removing material from a solid surface by vaporizing the material with a laser beam.
