In the December 2009 issue of the Journal of General Physiology, Moss et al. report a comprehensive investigation employing Förster resonance energy transfer (FRET) to study the {gamma}-amino acid (GABA) transporter GAT1, a member of the family that includes transporters for neurotransmitters dopamine (DAT), serotonin (SERT), norepinephrine (NET) and glycine (GlyT). http://www.physorg.com/news178803576.html Medicine & Health Mon, 30 Nov 2009 11:50:01 EST news178803576 Research conducted by University of Minnesota scientists, in collaboration with Celladon Corporation, has led to the invention of technology to more rapidly identify compounds for the treatment of heart failure. http://www.physorg.com/news178213416.html Medicine & Health Mon, 23 Nov 2009 16:10:06 EST news178213416 (PhysOrg.com) -- In order to effectively fight pathogens, even at remote areas of the human body, immune cells have to move quickly and in a flexible manner. http://www.physorg.com/news177676884.html Biology Tue, 17 Nov 2009 11:30:03 EST news177676884 Sony Corp. today announced the development of a highly efficient wireless power transfer system that eliminates the use of power cables from electronic products such as television sets. Using this system, up to 60 Watts of electrical energy can be transferred over a distance of 50cm (at an efficiency of approximately 80%, approximately 60% including rectifier). http://www.physorg.com/news173714272.html Technology Fri, 02 Oct 2009 15:20:01 EST news173714272 (PhysOrg.com) -- Generally, scientists prefer to avoid the concept of perpetual motion. The idea of a machine that could produce movement that goes on forever, and using that movement to generate an endless stream of energy, is usually considered more science fiction than science. But recently, physicist Pavel Ivanov has investigated previous speculation that an exotic fluid with unusual properties could cause energy to flow continuously between different regions of space, resulting in a runaway transfer of energy. If an advanced civilization were able to construct a device to capture this energy, it might finally possess its own "perpetuum mobile" -- or perpetual motion. http://www.physorg.com/news172225206.html Physics Tue, 15 Sep 2009 09:50:02 EST news172225206 (PhysOrg.com) -- UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere. http://www.physorg.com/news171791091.html Space & Earth Thu, 10 Sep 2009 08:45:33 EST news171791091 Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes. The research, published today in Nature Methods, opens the door to the hidden world of zinc biology by giving scientists an accurate way of measuring the concentration of zinc and its location in cells for the first time. http://www.physorg.com/news170860634.html Medicine & Health Sun, 30 Aug 2009 14:18:01 EST news170860634 The University of Georgia Research Foundation, Inc. (UGARF) and the University of Puerto Rico have granted an international, non-exclusive license for a portfolio of glow-in-the-dark pigments that can be designed to emit light in any color of the visible spectrum for nearly a day. Performance Indicator, LLC, of Lowell, Mass., acquired the license. http://www.physorg.com/news169751346.html Physics Mon, 17 Aug 2009 18:09:55 EST news169751346 Neurons communicate with each other with the help of nano-sized vesicles. Disruption of this communication process is responsible for many diseases and mental disorders like e.g. depression. Nerve signals travel from one neuron to another through vesicles - a nano-sized container loaded with neurotransmitter molecules. A vesicle fuses with the membrane surrounding a neuron, releases neurotransmitters into the surroundings that are detected by the next neuron in line. However, we still lack a more detailed understanding of how the fusion of vesicles occurs on the nano-scale. http://www.physorg.com/news168770252.html Nanotechnology Thu, 06 Aug 2009 09:50:05 EST news168770252 One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators at Johns Hopkins University has developed a quantum dot-based method that can quantify DNA methylation in premalignant cells harvested from human patients. http://www.physorg.com/news167412363.html Nanotechnology Thu, 23 Jul 2009 14:30:02 EST news167412363 (PhysOrg.com) -- Efficient energy transport plays an important role in the development of optoelectonic materials.

Over 30 years ago the spacecraft detected particles in solar wind which were 'hotter' than they should have been according to the existing theory expounded by the mathematician Andrey Kolmogorov in 1941. http://www.physorg.com/news154966140.html Physics Fri, 27 Feb 2009 14:09:31 EST news154966140 (PhysOrg.com) -- A new 3D model linking magnetic fields to the transfer of energy in space might help solve a physics mystery first observed in the solar wind 15 years ago. http://www.physorg.com/news154893335.html Physics Thu, 26 Feb 2009 17:56:36 EST news154893335 Collisions have consequences. Everyone knows that. Whether it's between trains, planes, automobiles or atoms, there are always repercussions. But while macroscale collisions may have the most obvious effects - mangled steel, bruised flesh - sometimes it is the tiniest collisions that have the most resounding repercussions. http://www.physorg.com/news134226755.html Physics Wed, 02 Jul 2008 14:12:35 EST news134226755
