An invisible shield has been discovered some 7,200 miles above Earth that blocks so-called 'killer electrons,' which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms.

The deliberate, large-scale intervention in the Earth's climate system is not a "quick fix" for global warming, according to new findings.

Elevated levels in the blood of the brain-enriched protein calpain-cleaved ±II-spectrin N-terminal fragment, known as SNTF, shortly after sports-related concussion can predict the severity of post-concussion symptoms in professional athletes, new research has found.

Centipedes, those many-legged creatures that startle us in our homes and gardens, have been genetically sequenced for the first time. An international team of over 100 scientists today reveals how this humble arthropod's DNA gave them new insight into how life developed on our planet.

A review of the scientific literature on Parkinson's disease shows that even the non-motor symptoms associated with the disease can contribute to the changes in body weight seen in patients (including those subjected to deep brain stimulation). Among the factors affecting eating habits and body weight there could be, for example, an impaired ability to derive pleasure from food and changes in motivation. These are important findings which can help to understand how to reduce these effects of Parkinson's that exacerbate an already negative clinical situation.

If natural or humanmade disaster strikes, causing global crop failures, the world won't starve -- providing they are willing to eat bacterial slime and bugs. "People have been doing catastrophic risk research for a while. But most of what's been done is dark, apocalyptic and dismal. It hasn't provided any real solutions," says the author of a new book that provides a more optimistic outlook.
