Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The solar steam sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.
The risk of catching some nasty germ in the Hudson River just started looking nastier. Disease-causing microbes have long been found swimming there, but now researchers have documented antibiotic-resistant strains in specific spots, from the Tappan Zee Bridge to lower Manhattan. The microbes identified are resistant to ampicillin and tetracycline, drugs commonly used to treat ear infections, pneumonia, salmonella and other ailments. The study is published in the current issue of the Journal of Water and Health.
