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.
An East Asian human fossil from Maba, China and dated to the late Middle Pleistocene age has provided evidence of interhuman aggression and human induced trauma occurred 126,000 years ago.

A report in the Proceedings of the National Academy of Sciences suggests that a 14 mm ridged, healed lesion with bone depressed inward to the brain resulted from localized blunt force trauma. Was it an accident or interhuman aggression?

The Maba cranium was discovered with the remains of other mammals in June 1958, in a cave at Lion Rock in Guangdong province, China. The Maba cranium and associated animal bones were unearthed at a depth of one meter by farmers removing cave sediments for fertilizer. 
A mathematical model could guide treatment decisions for advanced prostate cancer, in part by helping doctors predict how individual patients will respond to therapy based on the biology of their tumors.

These decisions would apply to treatment of cancer that has already spread beyond the prostate gland or that has recurred after initial treatments, such as surgery or radiation. Patients with this more advanced prostate cancer receive a therapy called androgen ablation, which inhibits production of testosterone – the culprit that allows a tumor to keep growing.
