| Stroke Damage in Mice Overcome by Training that ‘Rewires’ Brain Centers Posted: 06 Feb 2013 04:42 AM PST Johns Hopkins researchers have found that mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body, if the rodents are quickly subjected to physical conditioning that rapidly “rewires” a different part of the brain to take over lost function. |
| Unexpected finding about MS - Damaged nerve fibers survive Posted: 05 Feb 2013 05:13 PM PST Multiple sclerosis, a brain disease that affects over 400,000 Americans, causes movement difficulties and many neurologic symptoms. MS has two key elements: The nerves that direct muscular movement lose their electrical insulation (the myelin sheath) and cannot transmit signals as effectively. And many of the long nerve fibers, called axons, degenerate. |
| Mammogram Every Two Years Has Same Benefit As Yearly Mammogram for Older Women Posted: 05 Feb 2013 12:36 PM PST Among older women, getting a mammogram every two years was just as beneficial as getting a mammogram annually, and led to significantly fewer false positive results, according to a study led by UC San Francisco. |

| India joined with Asia 10 million years later than previously thought Posted: 05 Feb 2013 12:04 PM PST The peaks of the Himalayas are a modern remnant of massive tectonic forces that fused India with Asia tens of millions of years ago. Previous estimates have suggested this collision occurred about 50 million years ago, as India, moving northward at a rapid pace, crushed up against Eurasia. The crumple zone between the two plates gave rise to the Himalayas, which today bear geologic traces of both India and Asia. Geologists have sought to characterize the rocks of the Himalayas in order to retrace one of the planet’s most dramatic tectonic collisions. |
