Long assumed to be destructive to tissues and cells, “free radicals” generated by the cell’s mitochondria—the energy producing structures in the cell—are actually beneficial to healing wounds. That’s the conclusion of biologists at UC San Diego who discovered that “reactive oxygen species”—chemically reactive molecules containing oxygen, such as peroxides, commonly…

Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26.
