Physicists help biologists to understand protein folding
Physicists at UC Santa Barbara have created a microscopic device to assist biologists in making very fast molecular measurements that aid the understanding of protein folding. This development may help elucidate ...
Breaking the chain: 'Molecular cap' blocks processes that lead to Alzheimer's, HIV
(PhysOrg.com) -- A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer's disease and prevent the sexual transmission of HIV.
Novel compound selectively kills cancer cells
A cancer cell may seem out of control, growing wildly and breaking all the rules of orderly cell life and death. But amid the seeming chaos there is a balance between a cancer cell's revved-up metabolism and skyrocketing ...
