(PhysOrg.com) -- Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported. http://www.physorg.com/news187458147.html Space & Earth Wed, 10 Mar 2010 15:43:34 EST news187458147 (PhysOrg.com) -- What if space held the key to producing alternative energy crops on Earth? That's what researchers are hoping to find in a new experiment on the International Space Station. http://www.physorg.com/news187456979.html Space & Earth Wed, 10 Mar 2010 15:24:27 EST news187456979 Some laws are made to be broken, and others are made to be followed. A team of IBM Researchers in collaboration with two Swiss partners are looking to keep one law in particular alive and well for another 15 years: Moore's Law. The law states that the number of transistors that can be placed inexpensively on an integrated circuit will double every 18 months. More than 50 years old, this law is still in effect, but to extend it as long as 2020 will require a change from mere transistor scaling to novel packaging architectures such as so-called 3D integration, the vertical integration of chips. http://www.physorg.com/news187454589.html Nanotechnology Wed, 10 Mar 2010 15:20:01 EST news187454589 Current drugs used to treat heart failure and arrhythmias (irregular heartbeat) have limited effectiveness and have side effects. New basic science findings from a University of Iowa study suggest a way that treatments could potentially be refined so that they work better and target only key heart-related mechanisms. http://www.physorg.com/news187453002.html Medicine & Health Wed, 10 Mar 2010 14:16:54 EST news187453002 (PhysOrg.com) -- Think you need a lot of coffee to get going in the morning?

That`s the kind of power the experimental car, the "Carpuccino," needs just to travel one mile! http://www.physorg.com/news187452326.html Technology Wed, 10 Mar 2010 14:06:50 EST news187452326 (PhysOrg.com) -- The arguments against pornography are many, ranging from insistence that porn degrades women and is morally reprehensible to the assertion that pornography viewing is the cause of sex crimes. However, over the years, there have been numerous studies done on this subject. And, reports The Scientist, it appears that there are links between sex crimes and pornography. Just not the sort of links many of us might have expected. Instead of causing sex crimes, porn might actually contribute to reducing their incidence. http://www.physorg.com/news187448961.html Other Sciences Wed, 10 Mar 2010 14:00:01 EST news187448961 About four out of every 10 cells in the brain are so-called oligodendrocytes. These cells produce the all-important myelin that coats nerve tracts, ensuring fast, energy-efficient transmission of nerve impulses. Mixed among them are proliferating but not particularly proficient precursor cells that are destined to become oligodendrocytes when needed but, for now, remain suspended in an immature, relatively undifferentiated state somewhere between stem cell and adult oligodendrocyte. http://www.physorg.com/news187448771.html Medicine & Health Wed, 10 Mar 2010 13:07:06 EST news187448771 Hearing scientist Daniel Polley, Ph.D., an investigator at Massachusetts Eye and Ear Infirmary's Eaton-Peabody Laboratories of Auditory Physiology, has gained new insight into why a relatively short-term hearing deprivation during childhood may lead to persistent hearing deficits, long after hearing is restored to normal. The research, featured on the cover on the March 11 issue of the journal Neuron, reveals that, much like the visual cortex, development of the auditory cortex is quite vulnerable if it does not receive appropriate stimulation at just the right time. http://www.physorg.com/news187448448.html Medicine & Health Wed, 10 Mar 2010 13:01:18 EST news187448448 An analysis of more than 70,000 galaxies by University of California, Berkeley, University of Zurich and Princeton University physicists demonstrates that the universe - at least up to a distance of 3.5 billion light years from Earth - plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity. http://www.physorg.com/news187447655.html Physics Wed, 10 Mar 2010 13:00:05 EST news187447655 A puzzle that has baffled scientists for centuries - why some birds appear to be male on one side of the body and female on the other - has been solved by researchers. http://www.physorg.com/news187447481.html Biology Wed, 10 Mar 2010 13:00:04 EST news187447481 The smell of sea salt in the air is a romanticized feature of life along a seacoast.

They are often economically impoverished and socially isolated, which results in increased conflict, systematic violence and warfare, within and between communities as the new immigrants interact with and compete with the previously established inhabitants. Now, University of Missouri researcher Todd VanPool believes pottery found throughout the North American Southwest comes from a religion of peace-seeking women in the violent, 13th-century American Southwest. These women sought to find a way to integrate newly immigrating refugees and prevent the spread of warfare that decimated communities to the north. http://www.physorg.com/news187440656.html Other Sciences Wed, 10 Mar 2010 10:51:32 EST news187440656 Researchers at North Carolina State University have developed a new analytical method that opens the door to faster processing of large amounts of information, with applications in fields as diverse as the military, medical diagnostics and homeland security. http://www.physorg.com/news187439321.html Technology Wed, 10 Mar 2010 10:29:08 EST news187439321 (PhysOrg.com) -- The best hybrid cars of today can only deliver about 48 miles per gallon. By using this newly developed fuel injection system a test vehicle was measured at achieving 64 miles per gallon in highway driving. This is approximately a 50% increase in fuel efficiency in a gasoline engine. http://www.physorg.com/news187436599.html Technology Wed, 10 Mar 2010 09:45:40 EST news187436599 (PhysOrg.com) -- At very cold temperatures, in the absence of light, a photomultiplier will spontaneously emit single electrons. The phenomenon, which is called "cryogenic electron emission," was first observed nearly 50 years ago. Although scientists know of a few causes for electron emission without light (also called the dark rate) - including heat, an electric field, and ionizing radiation - none of these can account for cryogenic emission. Usually, physicists consider these dark electron events undesirable, since the purpose of a photomultiplier is to detect photons by producing respective electrons as a result of the photoelectric effect. http://www.physorg.com/news187421719.html Physics Wed, 10 Mar 2010 08:30:02 EST news187421719 Researchers at Stanford University have successfully developed brand new concept of organic lighting-emitting diodes (OLEDs) with a few nanometer of graphene as transparent conductor.
