Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. http://www.physorg.com/news155471367.html Nanotechnology Thu, 05 Mar 2009 10:30:08 EST news155471367 Compounds extracted from green vegetables such as broccoli and cabbage could be a potent drug against melanoma, according to cancer researchers. Tests on mice suggest that these compounds, when combined with selenium, target tumors more safely and effectively than conventional therapy. http://www.physorg.com/news155132202.html Medicine & Health Sun, 01 Mar 2009 12:17:19 EST news155132202 Diabetes patients undergoing team-based care do not save more in treatment costs under Medicare and Medicaid than other patients, but they are healthier, according to a recent study. http://www.physorg.com/news154876188.html Medicine & Health Thu, 26 Feb 2009 13:10:32 EST news154876188 (PhysOrg.com) -- The oldest isolated pulsar ever detected in X-rays has been found with NASA's Chandra X-ray Observatory. This very old and exotic object turns out to be surprisingly active. http://www.physorg.com/news154871702.html Space & Earth Thu, 26 Feb 2009 11:55:52 EST news154871702 The rate of ad clicks from sponsored and non-sponsored links was reported in a recent study conducted by researchers from Penn State and the Queensland University of Technology. http://www.physorg.com/news154786609.html Technology Wed, 25 Feb 2009 12:17:23 EST news154786609 The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State. http://www.physorg.com/news154008410.html Space & Earth Mon, 16 Feb 2009 12:07:21 EST news154008410 A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher. http://www.physorg.com/news153830013.html Chemistry Sat, 14 Feb 2009 10:35:16 EST news153830013 Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch. http://www.physorg.com/news153578273.html Nanotechnology Wed, 11 Feb 2009 12:38:29 EST news153578273 (PhysOrg.com) -- A team of researchers, including John Johnson, professor of psychology at Penn State DuBois, have discovered that literature may inspire readers to be ethical members of society. "As an evolutionary psychologist," said Johnson, "I am especially interested in the impact of literature on the emotions of the reader, and in what function these emotions serve." http://www.physorg.com/news152900319.html Other Sciences Tue, 03 Feb 2009 16:19:04 EST news152900319 High levels of certain proteins in the spinal fluid could signal the onset of Lou Gehrig's disease, according to researchers. The discovery of these biomarkers may lead to diagnostic kits for early diagnosis, accurately measuring the progression of the disease and monitoring the effects of treatment. http://www.physorg.com/news152370759.html Medicine & Health Wed, 28 Jan 2009 13:13:00 EST news152370759 Scientists at Penn State University and the Virginia Commonwealth University have discovered a way to produce hydrogen by exposing selected clusters of aluminum atoms to water. The findings are important because they demonstrate that it is the geometries of these aluminum clusters, rather than solely their electronic properties, that govern the proximity of the clusters' exposed active sites. The proximity of the clusters' exposed sites plays an important role in affecting the clusters' reactions with water. The team's findings will be published in the 23 January 2009 issue of the journal Science. http://www.physorg.com/news151856915.html Physics Thu, 22 Jan 2009 14:29:13 EST news151856915 All the genes that the exotic Tasmanian Tiger inherited only from its mother will be revealed by an international team of scientists in a research paper to be published on 13 January 2009 in the online edition of Genome Research. The research marks the first successful sequencing of genes from this carnivorous marsupial, which looked like a large tiger-striped dog and became extinct in 1936. The research also opens the door to the widespread, nondestructive use of museum specimens to learn why mammals become extinct and how extinctions might be prevented. http://www.physorg.com/news151002115.html Biology Mon, 12 Jan 2009 17:01:55 EST news151002115 An analysis of an 18,000-year-old fossil, described as the remains of a diminutive humanlike creature, proves that genuine cave-dwelling "hobbits" once flourished in Southeast Asia, according to a Long Island anthropologist who conducted X-ray studies of a skull. http://www.physorg.com/news150654813.html Other Sciences Thu, 08 Jan 2009 16:33:33 EST news150654813
