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.
The climate change effect of CO2 released from peat may be far greater than assumed.
Drought causes peat to release far more carbon dioxide into the atmosphere than has previously been realized, according to new research.
Before human embryonic stem cells can be examined for therapeutic potential it must be determined whether or not transplanted cells can functionally integrate into target organs or tissues.
Human embryonic stem cells (hESC), and induced pluripotent stem cells(iPS Cells), can give rise to all of the 220 types of tissues in the human body, and have been directed in the lab to become many types of cells, including brain cells.
