A class of engineered nanoparticles -- gold-centered spheres smaller than viruses -- has been shown safe when administered by two alternative routes in a mouse study led by investigators at the Stanford University School of Medicine. This marks the first step up the ladder of toxicology studies that, within a year and a half, could yield to human trials of the tiny agents for detection of colorectal and possibly other cancers.

The first research to actively analyze adult male sea turtles (Caretta caretta) using satellite tracking to link geography with pollutants has revealed the potential risks posed to this threatened species by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles.
