Simple chemical procedure augments therapeutic potential of stem cells
Adult stem cells resemble couch potatoes if they hang out and divide in a dish for too long. They get fat and lose key surface proteins, which interferes with their movement and reduces their therapeutic potential. Now, via a simple chemical procedure, researchers have found a way to get these... view more (2008-10-31)

Progeny of blind cavefish can regain their sight

Ames Laboratory beefing up magnets for electric-drive cars
One of the roadblocks for electric motor technology is that as operating temperatures go up, the magnets in the motors get weaker, resulting in a drop in power. Ames Laboratory Researcher Iver Anderson and his team have developed a new magnetic alloy that maintains its strong magnetic properties... view more (2008-01-10)
