Nanoparticles originally developed for industry have an unexpected effect: They triple or even quadruple the life of rat brain cells, suggesting that they could help extend human lifespan and decrease age-related health problems. It has been predicted that nanotechnology will revolutionize modern medicine, through such things as new materials that are more easily absorbed by human cells. Discovering the health effects of one such material, a nano-oxide particle, involved a collaboration between a molecular biologist and a nanoscientist at the University of Central Florida. Antioxidant nanotechnology The two researchers are Beverly Rzigalinski, an assistant molecular biology professor, and Sudipta Seal,...
