| Figuring Out The Heads Or Tails Decision In Regeneration
October 9, 2009 at 8:00 pm
|
| Wounds trigger regeneration in planaria, a flatworm commonly studied for its regenerative capabilities. Until now, no molecular connection between wounding and the onset of regeneration of an entire head or tail in planaria had been identified. Although animals such as planaria and starfish can regrow virtually any part of their bodies, humans have restricted regenerative capabilities. A better understanding of regeneration could one day benefit patients with traumatic injuries, such as amputations or nerve damage. |

| First 'One-way Roads' For Light Could Lead To Simpler Lightwave Technology
October 9, 2009 at 2:00 pm
|
| Light readily bounces off obstacles in its path. Some of these reflections are captured by our eyes, thus participating in the visual perception of the objects around us. In contrast to this usual behavior of light, researchers have implemented for the first time a one-way structure in which microwave light flows losslessly around obstacles or defects. This concept, when used in lightwave circuits, might one day reduce their internal connections to simple one-way conduits with much improved capacity and efficiency. |

| Too Much Of A Good Thing? Scientists Explain Cellular Effects Of Vitamin A Overdose And Deficiency
October 9, 2009 at 2:00 am
|
| If a little vitamin A is good, more must be better, right? Wrong!

This is particularly important as combinations of foods, drinks, creams and nutritional supplements containing added vitamin A make an overdose more possible than ever before. |
| If Only The Weeds Would Keep Their Genes To Themselves
October 9, 2009 at 2:00 am
|
| The ecological and economic impacts of gene flow between crops and their weedy relatives are significant.
