(PhysOrg.com) -- Soldiers returning from war who have lost a leg could lead a more active lifestyle with the help of a technology being developed by Oak Ridge National Laboratory researchers. http://phys.org/news244359766.html Technology Thu, 29 Dec 2011 06:00:01 EST news244359766 What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new research suggests that multiple cell types are needed to regrow the complete organ, at least in zebrafish. http://phys.org/news224768144.html Biology Mon, 16 May 2011 12:36:02 EST news224768144 University of Houston researchers are helping the Pentagon build reliable mind-controlled prosthetic devices that military and civilian amputees can use the rest of their lives. http://phys.org/news213985697.html Medicine & Health Tue, 11 Jan 2011 16:40:03 EST news213985697 (PhysOrg.com) -- An artificial foot that recycles energy otherwise wasted in between steps could make it easier for amputees to walk, its developers say. http://phys.org/news185607252.html Technology Wed, 17 Feb 2010 05:34:33 EST news185607252 (PhysOrg.com) -- New research has shown that body images can be formed independently of external sensory inputs, and that the phantom limbs of amputees can be trained to carry out tasks that would be impossible for real limbs. http://phys.org/news175938091.html Medicine & Health Wed, 28 Oct 2009 10:20:04 EST news175938091 (PhysOrg.com) -- Last year Joel Sadler and his classmates faced a daunting challenge in their Biomedical Device Design and Evaluation course: Create a low-cost, high-performance prosthetic knee joint for amputees in the developing world. Dubbed the JaipurKnee Project, the team aimed to help rectify lives ravaged by war and diseases such as diabetes. http://phys.org/news159030845.html Medicine & Health Wed, 15 Apr 2009 16:15:28 EST news159030845
