(PhysOrg.com) -- Scientists have discovered a new type of stem cell in the skin that acts surprisingly like certain stem cells found in embryos: both can generate fat, bone, cartilage, and even nerve cells. These newly-described dermal stem cells may one day prove useful for treating neurological disorders and persistent wounds, such as diabetic ulcers, says Freda Miller, an HHMI international research scholar. http://www.physorg.com/news179399989.html Medicine & Health Mon, 07 Dec 2009 09:20:29 EST news179399989 Despite advances in treatment regimens and the best efforts of nurses and doctors, about 70% of all people with severe burns die from related infections.

Two words explain how it works: "I believe." It's the placebo effect - the ability of a dummy pill or a faked treatment to make people feel better, just because they expect that it will. It's the mind's ability to alter physical symptoms, such as pain, anxiety and fatigue. http://www.physorg.com/news177082827.html Medicine & Health Tue, 10 Nov 2009 13:45:24 EST news177082827 A drug currently under development by the University of Pittsburgh School of Medicine may help bone fractures heal more quickly after radiation exposure, according to a study by Pitt researchers.
