Plain yogurt can sweeten your breath, according to a study presented to the International Association for Dental Research. Eating yogurt daily for six weeks reduced levels of offensive compounds produced by bacteria in the mouth...
That doesn't mean life once thrived on Mars, but it's a tantalizing sign. So is methane found in the Martian air. It could be volcanic, but methane is more often produced by living organisms. If bacteria still live under Mars' surface, this could be their calling card. Opportunity and Spirit can't detect bacteria directly, but they're not finished unearthing secrets. Spirit's discovery of an intact meteorite was totally unexpected, and the rover should get a dramatic panoramic view in a few weeks when it reaches the crest of the Columbia Hills. "I have no idea...
...cinematic take on the emerging science of astrobiology, the search for life in other worlds. Paradoxically, astrobiologists are equally fascinated with outer space and the ocean depths, where water superheated by magma from the Earth's crust spews from cracks called hydrothermal vents and sustains a bizarre menagerie of bacteria and other aquatic life...
...Proportion of airplanes nationwide found to have fecal coliform bacteria in their drinking water...
...build a new kind of "optical trap"--a device that splits a laser beam and uses it to capture particles of a single substance. They knew that multiple traps, used in tandem, could let scientists play traffic cops on a molecular level, separating a substance into component parts--removing bacteria from blood, for example. For a year, Grier and Dufresne had been trying out fancy glass splitters, but nothing had done the trick. As a joke, Grier tried a $5 piece of plastic. "It should not have worked," he says. But it did: the "cheesy piece of plastic" split...
