A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds. The research may help explain why water quality tests don't always accurately capture health risks...

Cheaper clean-energy technologies could be made possible thanks to a new discovery. An important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth....

Monell researchers identified odorants from human skin cells that can be used to identify melanoma, the deadliest form of skin cancer. In addition, a nanotechnology-based sensor could utilize the odor profiles to reliably differentiate melanoma cells from normal skin cells. Non-invasive odor...

Researchers at the University of Waterloo in Ontario are using photonics in their quest to "bring the lab to the sample," developing sophisticated micro instruments that scavenge power from sunlight, body heat, or other sources, for uses such as monitoring water quality or assessing bridge safety....
