Historians know that gravestones can reflect the lives of people whose memories are lost in time, and they have long scoured old burial sites to piece together the stories of those who rest there. http://www.physorg.com/news179520331.html Space & Earth Tue, 08 Dec 2009 18:48:03 EST news179520331 (PhysOrg.com) -- A single bacterium can act alone, performing the same kinds of actions that a group normally does. The behavior of that bacterium can be manipulated at the cellular level. That`s the intriguing finding by a group of researchers from UNM, the Dartmouth Medical School, the New Mexico Veterans Health Care System, and Sandia National Laboratories. The results are reported in the Nov. 22 issue of Nature Chemical Biology. A possible application is halting drug resistant bacteria found in hospital settings. http://www.physorg.com/news179520110.html Chemistry Tue, 08 Dec 2009 18:42:40 EST news179520110 (PhysOrg.com) -- Being irritable, grumpy and seeking social isolation are also hallmarks of depression, and could explain the Grinch's disdain for the Who -- the tall and the small -- his mistreatment of his dog Max and, ultimately, why he tried to stop Christmas from coming. http://www.physorg.com/news179519904.html Medicine & Health Tue, 08 Dec 2009 18:38:58 EST news179519904 (PhysOrg.com) -- The huge increases in the power and capacity of computers, cell phones and communications networks in the last 40 years have been the result of ever-shrinking silicon transistors.
