(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 The IEEE today announced that its Standards Board has ratified the IEEE 802.11n -2009 amendment, defining mechanisms that provide significantly improved data rates and ranges for wireless local area networks (WLANs). http://www.physorg.com/news172175364.html Technology Mon, 14 Sep 2009 19:50:03 EST news172175364 An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved. http://www.physorg.com/news171899385.html Space & Earth Fri, 11 Sep 2009 14:50:22 EST news171899385 (PhysOrg.com) -- UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere.

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 Toshiba Corporation today announced the launch of the world's first 64GB SDXC Memory Card with the world's fastest data transfer rate compliant with the new SD Memory Standard Ver. 3.00, UHS 104. http://www.physorg.com/news168622732.html Electronics Tue, 04 Aug 2009 16:40:03 EST news168622732 (AP) -- Hanqi Miao said she wanted to donate her eggs to help infertile couples reproduce, but she acknowledged the money is good, too: She said she'll be paid about $5,000. http://www.physorg.com/news168240792.html Biology Fri, 31 Jul 2009 06:33:37 EST news168240792 (PhysOrg.com) -- A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists had never been able to confirm, or measure, this breakdown in practice. For the first time, however, MIT researchers have achieved this feat, and determined that the heat transfer can be 1,000 times greater than the law predicts. http://www.physorg.com/news168101848.html Physics Wed, 29 Jul 2009 15:58:36 EST news168101848 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.
