Super-sizing a cancer drug minimizes side effects.July 28,2010.

Super-sizing a cancer drug minimizes side effects One of the first chemotherapy drugs given to patients diagnosed with cancer — especially lung, ovarian or breast cancer — is cisplatin, a platinum-containing compound that gums up tumor cells’ DNA. Cisplatin does a good job of killing those tumor cells, but it can also seriously damage the kidneys, which receive high doses of cisplatin because they filter the blood.

Turning down the noise in graphene.August 6,2010.

Turning down the noise in graphene Graphene is a two-dimensional crystalline sheet of carbon atoms - meaning it is only one atom thick - through which electrons can race at nearly the speed of light - 100 times faster than they can move through silicon. This plus graphene's incredible flexibility and mechanical strength make the material a potential superstar for the electronics industry. However, whereas the best electronic materials feature a strong signal and weak background noise, attaining this high signal-to-noise ratio has been a challenge for both single and bi-layers of graphene, especially when placed on a substrate of silica or some other dielectric. One of the problems facing device developers has been the lack of a good graphene noise model.Source:Lawrence Berkeley National Laboratory
