Searching for an environmentally friendly way to produce cheap hydrogen as a fuel, researchers at Oregon State University are turning to microbes that have been doing the job for billions of years. http://www.physorg.com/news157140535.html Technology Tue, 24 Mar 2009 19:09:47 EST news157140535 Scientists at the University of Liverpool have demonstrated how a single-celled organism, living freely in the environment, could be a source of Salmonella transmission to animals and humans. http://www.physorg.com/news157038671.html Biology Mon, 23 Mar 2009 14:51:53 EST news157038671 (PhysOrg.com) -- Not far beneath the ocean's surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling's Twilight Zone: a sharp variation in marine currents that traps billions of these single-celled organisms and sends them tumbling until a shift in wind or tide alters the currents and sets them free. http://www.physorg.com/news154275440.html Biology Thu, 19 Feb 2009 14:17:51 EST news154275440 The bacterium Escherichia coli, one of the best-studied single-celled organisms around, is a master of industrial efficiency. This bacterium can be thought of as a factory with just one product: itself. It exists to make copies of itself, and its business plan is to make them at the lowest possible cost, with the greatest possible efficiency. Efficiency, in the case of a bacterium, can be defined by the energy and resources it uses to maintain its plant and produce new cells, versus the time it expends on the task. http://www.physorg.com/news152966446.html Biology Wed, 04 Feb 2009 10:42:12 EST news152966446 (PhysOrg.com) -- It has a beautiful, but also an unpleasant side: crystallization determines the shape of precious stones, but also causes the lime scale in washing machines. How this comes about, has been known for a long time - or has it? http://www.physorg.com/news150998079.html Chemistry Mon, 12 Jan 2009 15:54:39 EST news150998079
