Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

A universal influenza vaccine -- so-called because it could potentially provide protection from all flu strains for decades -- may become a reality.

Researchers have documented potential cellular damage from "fullerenes" -- soccer-ball-shaped, cage-like molecules composed of 60 carbon atoms. The team also noted that this particular type of damage might hold hope for treatment of Parkinson's disease, Alzheimer's disease or even cancer.

Scientists have discovered a way to use lasers and nanoparticles to identify and treat individual diseased cells with tiny vapor "nanobubbles." In a new study, the scientists described how to use the method to explode nanobubbles and kill cancer cells.
