Research on muscle fatigue has largely been confined to the muscle itself. That makes sense, where there is burn, there is fire.  But motivation and will power turns out to have a greater impact on muscle fatigue than previously believed, according to a joint research project between the University of Zurich and ETH Zurich has shifted the focus to brain research.

The researchers discovered neuronal processes for the first time that are responsible for reducing muscle activity during muscle-fatiguing exercise. The third and final part of this series of experiments, which was conducted by Lea Hilty as part of her doctoral thesis at the University of Zurich, has now been published in the European Journal of Neuroscience.

Kinect for Xbox 360 has an update coming today that brings voice control to living room entertainment.

 You Say It, Xbox Finds It 

How long does it take you to search and find your favorite movie or TV show? Do you find yourself searching hundreds of channels and multiple services and TV inputs? What if the entertainment you craved was simple, discoverable and exactly what you wanted at that particular moment?

The controversy over whether or not violent video games are potentially harmful to players has been debated for many years, even making it to the Supreme Court in 2010. There has been little scientific evidence demonstrating that the games have a prolonged negative neurological effect but sustained changes in the region of the brain associated with cognitive function and emotional control were found in young adult men after one week of playing violent video games, according to study results presented at the annual meeting of the Radiological Society of North America.

The debate over the actual benefit of antioxidants may be ongoing but the studies keep coming in. Regardless of cardiovascular disease medical history, Swedish women who ate an antioxidant-rich diet had fewer strokes, shows the results of a new survey.

Oxidative stress is an imbalance between the production of cell-damaging free radicals and the body's ability to neutralize them. It leads to inflammation, blood vessel damage and stiffening.

Antioxidants such as vitamins C and E, carotenoids and flavonoids can inhibit oxidative stress and inflammation by scavenging the free radicals. Antioxidants, especially flavonoids, may also help improve endothelial function and reduce blood clotting, blood pressure and inflammation.

Researchers using the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite have confirmed major reductions in the levels of sulfur dioxide, a key pollutant generated by coal power plants which contributes to the formation of acid rain, in the eastern United States. 

People who meditate seem to be able 'switch off' areas of the brain associated with daydreaming as well as psychiatric disorders such as autism and schizophrenia, according to a new brain imaging study published in the Proceedings of the National Academy of Sciences.

Meditation's ability to help people stay focused on the moment has been associated with increased happiness levels, said Judson A. Brewer, assistant professor of psychiatry and lead author of the study. To find out more, the team conducted functional magnetic resonance imaging scans on both experienced and novice meditators as they practiced three different meditation techniques.
