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.
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 [...]

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.

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.

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.

The checkout and calibration of the NASA/ESA Hubble Space Telescope has been interrupted to aim the recently refurbished observatory at a new expanding spot on the giant planet Jupiter. The spot, caused by the impact of a comet or an asteroid, is changing from day to day in the planet’s cloud tops.

Cell Membranes Applied To Manufactured Surfaces Could Lead To New Class Of Self-assembling Materials
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.
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 [...]
