When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered. http://www.physorg.com/news178377237.html Biology Wed, 25 Nov 2009 13:14:44 EST news178377237 (PhysOrg.com) -- In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known "northern lights" in the solar system, flickering in shape and brightness high above the ringed planet. http://www.physorg.com/news178303936.html Space & Earth Tue, 24 Nov 2009 16:53:17 EST news178303936 (PhysOrg.com) -- The first large black holes in the universe likely formed and grew deep inside gigantic, starlike cocoons that smothered their powerful x-ray radiation and prevented surrounding gases from being blown away, says a new study led by the University of Colorado at Boulder. http://www.physorg.com/news178293451.html Space & Earth Tue, 24 Nov 2009 13:58:28 EST news178293451 Universitat Autňnoma de Barcelona (UAB, Spain) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells. http://www.physorg.com/news178279255.html Medicine & Health Tue, 24 Nov 2009 10:01:28 EST news178279255 (PhysOrg.com) -- NASA's Spitzer Space Telescope has contributed to the discovery of the youngest brown dwarf ever observed -- a finding that, if confirmed, may solve an astronomical mystery about how these cosmic misfits are formed. http://www.physorg.com/news178221292.html Space & Earth Mon, 23 Nov 2009 17:55:42 EST news178221292 (PhysOrg.com) -- Researchers at Sandia National Laboratories have built a machine that uses the sun's energy to convert carbon dioxide waste from power plants into transportation fuels such as gasoline, diesel, and jet fuel. The system could provide an alternative to carbon sequestration; instead of permanently storing CO2 underground, the CO2 could be recycled and put to use. http://www.physorg.com/news178203219.html Chemistry Mon, 23 Nov 2009 13:06:36 EST news178203219 Scientists at the Carnegie Institution have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for an entirely new way to approach the hydrogen-storage problem. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen (H2) under pressure to form a previously unknown solid with unusual bonding chemistry. The experiments are the first time these elements have been combined to form a stable compound. The discovery debuts a new family of materials, which could boost new hydrogen technologies. http://www.physorg.com/news178119983.html Chemistry Sun, 22 Nov 2009 13:47:08 EST news178119983 You don't always have to have a rocket to do rocket science. Sometimes a mere airplane will do - that is, a mere Boeing 747 toting a 17-ton, 9-foot wide telescope named SOFIA. http://www.physorg.com/news177874574.html Space & Earth Thu, 19 Nov 2009 17:50:02 EST news177874574 (PhysOrg.com) -- Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often. A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this. http://www.physorg.com/news177865593.html Nanotechnology Thu, 19 Nov 2009 15:07:50 EST news177865593 A team of researchers at the Worcester Polytechnic Institute Life Sciences and Bioengineering Center at Gateway Park has developed a new model system to study fungal infections. The system can be a powerful tool for screening potential drug targets for conditions like thrush, athlete's foot and vaginal yeast infections, which affect millions of people each year but are difficult to treat with existing medications. Using the new model, the researchers also identified a gene that may be a promising target for a new anti-fungal drug. http://www.physorg.com/news177851974.html Biology Thu, 19 Nov 2009 11:21:01 EST news177851974 Substances that provoke gastrointestinal symptoms in patients with eating disorders (ED) can impact negatively on their nutritional rehabilitation. An Australian research group has found that ingestion of fructose-sorbitol (F-S) provoked gastrointestinal symptoms in more than half of a group of female ED patients, and symptoms were more marked in the most underweight patients. These findings indicate that F-S provocative testing could play a valuable role in the clinical management of ED patients. http://www.physorg.com/news177847515.html Medicine & Health Thu, 19 Nov 2009 11:10:02 EST news177847515 (PhysOrg.com) -- A research group at Kyoto University has discovered that shocks are the primary energy sources that excite the galactic wind region of starburst galaxy NGC 253. Their images of the center of this galaxy, bright with intense star formation, have generated findings that substantially increase our meager knowledge of the physical properties of galactic winds and move us closer to understanding galaxy evolution. http://www.physorg.com/news177783331.html Space & Earth Wed, 18 Nov 2009 19:20:03 EST news177783331 A recent experiment at the DOE's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structure. http://www.physorg.com/news177787801.html Physics Wed, 18 Nov 2009 17:31:37 EST news177787801 Like surfers on monster waves, electrons can ride waves of plasma to very high energies in a very short distance. Scientists have proven that plasma acceleration works. Now they're developing it as a way to dramatically shrink the size and cost of particle accelerators for science, medicine, industry, and myriad other uses. http://www.physorg.com/news177786729.html Physics Wed, 18 Nov 2009 17:13:04 EST news177786729 (PhysOrg.com) -- NASA's Wide-field Infrared Survey Explorer, or Wise, is chilled out, sporting a sunshade and getting ready to roll. NASA's newest spacecraft is scheduled to roll to the pad on Friday, Nov. 20, its last stop before launching into space to survey the entire sky in infrared light. http://www.physorg.com/news177698029.html Space & Earth Tue, 17 Nov 2009 17:20:01 EST news177698029
