Since 2000, more than 2,000 servicemembers have suffered amputated limbs. DARPA's breakthrough research with advanced prosthetic limbs controlled by brain interfaces is well documented, but such research is currently limited to quadriplegics; practical applications of brain interfaces for amputees are still in the future. In contrast, nerve and muscle interfaces allow amputees to control advanced prosthetics in the near term. Recent demonstrations may give Wounded Warriors hope that they can soon take advantage of these breakthroughs. http://phys.org/news289215309.html Technology Fri, 31 May 2013 10:35:27 EST news289215309 White blood cells, or leukocytes, are the immune system's warriors. So when an infection or disease attacks the body, the system typically responds by sending more white blood cells into the fray. This means that checking the number of these cells is a relatively easy way to detect and monitor such conditions. http://phys.org/news283509894.html Chemistry Tue, 26 Mar 2013 09:45:01 EST news283509894 With the discovery of antibiotics, medicine acquired power on a scale never before possible to protect health, save lives, and reduce suffering caused by certain bacteria. But the power of antibiotics is now under siege because some virulent infections no longer respond to antibiotic drugs. http://phys.org/news278959645.html Biology Fri, 01 Feb 2013 17:20:02 EST news278959645 (Phys.org)—Using blue light, Duke University bioengineers have developed a system for ordering genes to produce proteins, an advance they said could prove invaluable in clinical settings as well as in basic science laboratories. http://phys.org/news268383016.html Biology Tue, 02 Oct 2012 07:50:33 EST news268383016 In a study published in the journal Cell on May 24, Cold Spring Harbor Laboratory (CSHL) scientists describe the three-dimensional atomic structure of a human protein bound to a piece of RNA that "guides" the protein's ability to silence genes. The protein, Argonaute-2, is a key player in RNA interference (RNAi), a powerful cellular phenomenon that has important roles in diverse biological processes, including an organism's development. http://phys.org/news257182123.html Biology Fri, 25 May 2012 16:33:05 EST news257182123 It's no wonder that medicine's effort to combat bacterial infections is often described as an arms race. When new drugs are developed to combat infections, the bacterial target invariably comes up with a deterrent. http://phys.org/news241712202.html Chemistry Mon, 28 Nov 2011 14:17:02 EST news241712202 It's no surprise that being a physician is a very stressful job and carries a lot of responsibility with it. http://phys.org/news208624142.html Medicine & Health Wed, 10 Nov 2010 15:30:19 EST news208624142
