Cannabis may help combat cancer-causing herpes viruses

...within white blood cells before they burst out and begin replicating. This reactivation of the virus boosts the number of cells infected thereby increasing the chances that the cells will become cancerous.

Scientists find nanowires capable of detecting individual viruses

...t this stage of viral activity that symptoms often begin to appear, but with viruses still present in limited numbers, they can be difficult to detect and treat. The nanowire arrays detect viruses suspended in fluids, whether bodily or otherwise. Lieber says that any anti-bioterror device built around nano...

We also found that excessive accumulation of this molecule in the pancreas will impair insulin release, thus it is possible that this molecule is the long searched for link between these two disorders." The res...
