| Lungfish provides insight to life on land: 'Humans are just modified fish' Posted: 04 Oct 2011 03:01 PM PDT A study into the muscle development of several different fish has given insights into the genetic leap that set the scene for the evolution of hind legs in terrestrial animals. This innovation gave rise to the tetrapods -- four-legged creatures, and our distant ancestors -- that made the first small steps on land some 400 million years ago.  |
| Hormone fights fat with fat: Orexin prevents obesity in mice by activating calorie-burning brown fat Posted: 04 Oct 2011 09:35 AM PDT Researchers have discovered that the hormone orexin activates calorie-burning brown fat in mice. Orexin deficiency is associated with obesity, suggesting that orexin supplementation could provide a new therapeutic approach for the treatment of obesity and other metabolic disorders. An orexin-based therapy would represent a new class of fat-fighting drugs -- one that focuses on peripheral fat-burning tissue rather than the brain's appetite control center.  |
| HIV: Cell-penetrating peptides for drug delivery act like a Swiss Army Knife Posted: 04 Oct 2011 09:13 AM PDT Scientists have identified how HIV TAT peptides can have multiple interactions with the membrane, the actin cytoskeleton, and specific cell-surface receptors to produce multiple pathways of translocation under different conditions. Moreover, because they now know how cell penetrating peptides work, it is possible to have a general recipe for reprogramming normal peptides into cell penetrating peptides.  |
| Robot brain implanted in a rodent: Researcher implants robotic cerebellum to repair motor function Posted: 03 Oct 2011 10:24 AM PDT With new cutting-edge technology aimed at providing amputees with robotic limbs, a researcher has successfully implanted a robotic cerebellum into the skull of a rodent with brain damage, restoring its capacity for movement.  |
