Scientists unveil piece of HIV protein that may be key to AIDS vaccine development
... specific antibody, known as b12, that can broadly neutralize
HIV. "Creating an HIV vaccine is one of the great scientific challenges of our time," says NIH Director Elias A. Zerhouni, M.D. "NIH researchers and their colleagues have revealed a gap in HIV's armor and have thereby opened a new avenue to meeting ...

Chemicals in brown algae may protect against skin cancer
... when eaten, these compounds get to skin cells and neutralize
the cancer-causing oxygen radicals that are produced by UV exposure." Laboratory research has shown that BAPs are strong antioxidants and may have anticancer properties. For this study, Stoner and his collaborators used a strain of hairless m...
