| Brief exposure to performance-enhancing drugs may be permanently 'remembered' by muscles Posted: 27 Oct 2013 05:56 PM PDT Brief exposure to anabolic steroids may have long lasting, possibly permanent, performance-enhancing effects, shows a new study.  |
| Posted: 27 Oct 2013 03:53 PM PDT The largest international study ever conducted on Alzheimer's disease (AD), the I-GAP (International Genomics Alzheimer's Project) consortium has identified 11 new regions of the genome involved in the onset of this neurodegenerative disease. This study gives an overview of the molecular mechanisms underlying the disease, opening up to a better understanding of the pathophysiology of AD.  |
| Cell nucleus protein in brown fat cells governs daily control of body temperature Posted: 27 Oct 2013 03:50 PM PDT Body temperature follows a 24-hour rhythm, peaking during the day, low at night. The benefit might be the conservation of energy while sleeping. It is also critical to be able to adapt to changes in ambient temperature regardless of the time of day. A new mouse study shows how body temperature rhythms are synchronized while maintaining the ability to adapt to changes in environmental temperature day or night.  |
| Scientists eye longer-term forecasts of U. S. heat waves Posted: 27 Oct 2013 03:50 PM PDT Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The new research could potentially enable forecasts of the likelihood of U.S. heat waves 15-20 days out, giving society more time to prepare for these often-deadly events.  |
| Smart neurons: Single neuronal dendrites can perform computations Posted: 27 Oct 2013 11:06 AM PDT When you look at the hands of a clock or the streets on a map, your brain is effortlessly performing computations that tell you about the orientation of these objects. New research has shown that these computations can be carried out by the microscopic branches of neurons known as dendrites, which are the receiving elements of neurons.  |
