An attention training program may be a viable and effective way to improve attention span in stroke survivors. Survivors who received attention training had higher improved rates of attention compared to patients receiving standard rehabilitation.

Researchers have developed a screening method that would use ionic liquids -- a special type of molten salt that becomes liquid under the boiling point of water (100 degrees Celsius) -- to separate carbon dioxide from its source, making it a cleaner, more viable and stable method than what is currently available.

Injured heart tissue normally can't regrow, but researchers now offer a groundwork for regenerating heart tissue after a heart attack, in patients with heart failure, or in children with congenital heart defects. They show that a growth factor involved in the development of the heart and nervous system can spur heart-muscle growth and recovery of cardiac function when injected systemically into animals after a heart attack.

Fake Internet postcards circulating through e-mail inboxes worldwide are carrying links to the virus known as Zeus Bot, said a computer forensics expert. Zeus Bot has been named America's most pervasive computer Botnet virus by Network World magazine, reportedly infecting 3.6 million US computers.

Fueled by caffeine teens are up late at night, and they aren't just focusing on homework. Web surfing, text messaging and gaming are keeping them up for hours into the night, according to a recent study.

Researchers now show that ants can accomplish a task more rationally than our -- multimodal, egg-headed, tool-using, bipedal, opposing-thumbed -- selves. This is not the case of humans being "stupider" than ants.

Australia's largest study of young drivers has shown that risky driving habits are putting young drivers at a significantly increased risk of crashing, irrespective of their perceptions about road safety. The study surveyed 20,000 young drivers and examined their crashes reported to police. Young drivers involved in the study who said they undertook risky driving were 50 percent more likely to crash.

The race is on for a successor to the popular ‘flash’ memory used in portable devices. Researchers think they have found a candidate in novel materials combined with a simple, easily fabricated ‘crossbar’ architecture.

Scientists have linked an overactive response by one of the immune system's key weapons against infection -- natural killer cells -- to biliary atresia in infants, a disease where blocked bile ducts can cause severe liver damage and death. The study shows blocking a gene that helps NK cells attack bile duct tissues may be a way to treat a common cause of liver disease in children.

Applying biological molecules from cell membranes to the surfaces of artificial materials is opening peepholes on the very basics of cell-to-cell interaction. Two new articles suggest that putting lipids and other cell membrane components on manufactured surfaces could lead to new classes of self-assembling materials for use in precision optics, nanotechnology, electronics and pharmaceuticals.
