Professor of Biochemistry Emad Tajkhorshid and colleagues have discovered that membrane transporters help not just sugars and other specific substrates cross from one side of a cellular membrane to the other—water also comes along for the ride. http://phys.org/news286725586.html Chemistry Thu, 02 May 2013 15:00:09 EST news286725586 (Phys.org) —A Purdue University-led team has revealed the proton transfer pathway responsible for a majority of energy storage in photosynthesis. Through photosynthesis, plants, algae and bacteria convert sunlight, carbon dioxide and water into chemical energy stored in the membrane of special cells, a process similar to charging a battery, said William A. Cramer, the Henry Koffler Distinguished Professor of Biological Sciences and research team leader. http://phys.org/news285877405.html Chemistry Mon, 22 Apr 2013 19:23:36 EST news285877405 (Phys.org)—While studying a mutant strain of yeast, Purdue University researchers may have found a new target for drugs to combat cholesterol and fungal diseases. http://phys.org/news281035808.html Chemistry Mon, 25 Feb 2013 17:30:44 EST news281035808 (Phys.org)—To remove waste from cells, a class of membrane-sculpting proteins create vesicles—molecular trash bags—that carry old and damaged proteins from the surface of cellular compartments into internal recycling plants where the waste is degraded and components are reused. http://phys.org/news270196244.html Biology Tue, 23 Oct 2012 09:00:01 EST news270196244 During the final stage of cell division, a short-lived contractile ring constricts the cellular membrane and eventually separates the dividing cell in two. Although this "molecular muscle's" composition, mainly actin and myosin, is similar to its skeletal counterpart, the force-producing mechanism is fundamentally different, report researchers at the Stowers Institute for Medical Research in the June 12, 2012, issue of Developmental Cell. http://phys.org/news258632534.html Biology Mon, 11 Jun 2012 12:00:32 EST news258632534 A collaboration between Lehigh University physicists and University of Miami biologists addresses an important fundamental question in basic cell biology: How do living cells figure out when and where to grow? http://phys.org/news256562960.html Biology Fri, 18 May 2012 12:31:09 EST news256562960 (PhysOrg.com) -- Bacteria are able to build camouflaged homes for themselves inside healthy cells - and cause disease - by manipulating a natural cellular process. http://phys.org/news243611955.html Biology Tue, 20 Dec 2011 13:59:25 EST news243611955 Scientists at the University of Southampton have developed smart nanomaterials, which can disrupt the blood supply to cancerous tumours. http://phys.org/news229261570.html Nanotechnology Thu, 07 Jul 2011 12:46:34 EST news229261570 For the first time, scientists have built completely flat, two-layer ice. While theoreticians have predicted that such ices are formed by squeezing water molecules between two surfaces, scientists at Pacific Northwest National Laboratory and Ruhr-Universitat Bochum are the first to create it. All it took was collaboration, creativity, and the absence of pressure. http://phys.org/news171729768.html Chemistry Wed, 09 Sep 2009 15:47:28 EST news171729768
