Researchers discover why brain areas fail to work together in autism

In people with autism, the brain areas that perform complex analysis appear less likely to work together during problem solving tasks than in people who do not have the disorder, report researchers working in a network funded by the National Institutes of Health.

Study shows high survival for patients with torn aortas who get surgery

Nearly three years ago, actor John Ritter collapsed on the set of his sitcom, the victim of a rare but often deadly condition called aortic dissection - a tear in the largest blood vessel in the body.

Functionalized carbon nanotubes are non-cytotoxic and preserve the functionality of primary immune cells

Various types of carbon-based nanomaterials, such as buckyballs and nanotubes, have shown promise as drug delivery tools and imaging agents, but reports of toxicity associated with some of these materials have raised questions about their ultimate utility in clinical oncology.

Amazing brain repairs itself!

Doctors in the U.S. have discovered that the brain of a man so severely damaged in a car accident that he was left in a barely conscious state, has healed itself and he is now conscious and communicating with those around him.
