| How Aging Can Intensify Damage of Spinal Cord Injury Posted: 24 Jun 2014 06:52 PM PDT In the complex environment of a spinal cord injury, researchers have found that immune cells in the central nervous system of elderly mice fail to activate an important signaling pathway, dramatically lowering chances for repair after injury. These studies were the first to show that spinal cord injuries are more severe in elderly mice than in young adults, corroborating previous anecdotal findings from clinical settings. They also revealed a previously unknown player in the repair of spinal cord injuries in young adults. |
| Study shows greater potential for low-cost solar power plants Posted: 24 Jun 2014 06:40 PM PDT New analysis of large-scale 'concentrating solar power' plants suggests they could meet 70-80% of electricity demand if they are linked together. |
| Morphable surfaces could cut air resistance Posted: 24 Jun 2014 09:04 AM PDT There is a story about how the modern golf ball, with its dimpled surface, came to be: In the mid-1800s, it is said, new golf balls were smooth, but became dimpled over time as impacts left permanent dents. Smooth new balls were typically used for tournament play, but in one match, a player ran short, had to use an old, dented one, and realized that he could drive this dimpled ball much further than a smooth one. |
