Biochemists at The Scripps Research Institute (TSRI) have discovered a genetic sequence that can alter its host gene's activity in response to cellular energy levels. The scientists have found this particular energy-sensing switch in bacterial genes, which could make it a target for a powerful new class of antibiotics. If similar energy-sensing switches are also identified for human genes, they may be useful for treating metabolism-related disorders such as type 2 diabetes and heart disease. http://phys.org/news270018889.html Chemistry Sun, 21 Oct 2012 13:00:08 EST news270018889 (PhysOrg.com) -- Our attempts to use solar energy continue to be very ineffective; the true masters of this craft are photosynthetic plants, algae, and bacteria. Science is trying to emulate these organisms. http://phys.org/news205143988.html Nanotechnology Fri, 01 Oct 2010 09:26:43 EST news205143988 Researchers from Mount Sinai School of Medicine have enhanced our understanding of the mechanism by which cells achieve energy conversion, the process in which food is converted into the energy required by cells. This groundbreaking research helps scientists gain atomic-level insight into how organisms synthesize their major form of chemical energy. The researchers' findings were published in the August issue of PLoS Biology. http://phys.org/news201352926.html Biology Wed, 18 Aug 2010 12:30:19 EST news201352926 (PhysOrg.com) -- Virginia Commonwealth University researchers have found that the protein Stat3 plays a key role in regulating mitochondria, the energy-producing machines of cells. This discovery could one day lead to the development of new treatments for heart disease to boost energy in failing heart muscle or to master the abnormal metabolism of cancer. http://phys.org/news152374253.html Biology Wed, 28 Jan 2009 14:11:23 EST news152374253
