Taking Aim With Nanoparticle PEBBLEs

...rs of rats, and PEBBLE-based cancer treatments for people are a long way off. But "there's no doubt," said Kopelman, "that nanoparticles such as PEBBLEs can do a fantastic job for therapy, diagnostics and a combination of the two." Kopelman's collaborators on the work he will discuss in San Diego are Marti...

First real-time view of developing neurons reveals surprises, say Stanford researchers

... in our own brains all the time," Niell said. When people learn new skills or add memories to their overstuffed brains, new connections are required to retain that information. Some diseases also seem to be caused by brain connections not forming normally. Dyslexia, for example, may be caused by connection...

...trol fat formation in the body, then we could keep people leaner, lowering their chances of becoming insulin-dependent, and lowering the likelihood they would develop type II diabetes," Kniss said. He also suggested that the new approach might have commercial applications as a way of testing new drugs. "Sm...

UCSD discovery may help extend life of natural pesticide
