Iowa State University researchers are working to produce clean, renewable energy by developing a new, low-emissions burner and a new catalyst for ethanol production. http://www.physorg.com/news155829000.html Technology Mon, 09 Mar 2009 14:50:42 EST news155829000 (PhysOrg.com) -- Understanding how plants produce storage organs that humans use as food would be a valuable tool for science and for a hungry world. http://www.physorg.com/news155327379.html Biology Tue, 03 Mar 2009 18:30:57 EST news155327379 (PhysOrg.com) -- If you're looking to keep your job in these tough economic times, you might want to avoid talking about how your firm's cutbacks will make it harder for you to do your work. That's because those who regularly articulate workplace handicaps don't get much sympathy from co-workers, according to an Iowa State University management professor who has studied self-handicapping in the workplace. http://www.physorg.com/news155238267.html Other Sciences Mon, 02 Mar 2009 17:44:56 EST news155238267 (PhysOrg.com) -- A new study by psychologists from Iowa State University and Linfield College has found that TV ratings don't accurately reflect the aggressive content found in shows popular among children -- even cartoons. http://www.physorg.com/news154801488.html Medicine & Health Wed, 25 Feb 2009 16:25:12 EST news154801488 Research by an Iowa State University scientist suggests that cholesterol-reducing drugs known as statins may lessen brain function. http://www.physorg.com/news154632233.html Medicine & Health Mon, 23 Feb 2009 17:24:26 EST news154632233 (PhysOrg.com) -- Violent video games and movies make people numb to the pain and suffering of others, according to a research report published in the March 2009 issue of Psychological Science. http://www.physorg.com/news154282508.html Medicine & Health Thu, 19 Feb 2009 16:16:14 EST news154282508 In the hours following an outbreak of Salmonella, there are many questions. And answers can be hard to find. http://www.physorg.com/news152802866.html Biology Mon, 02 Feb 2009 13:15:17 EST news152802866 What is it with false confession? It seems crazy on the face of it, to take the blame for a crime you didn't commit. Yet experts have found that while some innocent confessors are mentally disturbed attention seekers, or taking the fall for someone else, most innocents who confess do so under stress, as an act of surrender, during a high stakes, high-pressure police interrogation. According to one estimate, fully a quarter of convictions later overturned by DNA evidence involved a false confession. http://www.physorg.com/news152383104.html Medicine & Health Wed, 28 Jan 2009 16:38:52 EST news152383104 Eyewitness testimony is a crucial part of many criminal trials even though research increasingly suggests that it may not be as accurate as we (and many lawyers) would like it to be. For example, if you witness a man in a blue sweater stealing something, then overhear people talking about a gray shirt, how likely are you to remember the real color of the thief's sweater? Studies have shown that when people are told false information about an event, they become less likely to remember what actually happened - it is easy to mix up the real facts with fake ones. However, there is evidence that when people are forced to recall what they witnessed (shortly after the event), they are more likely to remember details of what really happened. http://www.physorg.com/news152378697.html Medicine & Health Wed, 28 Jan 2009 15:25:17 EST news152378697 (PhysOrg.com) -- A researcher at Iowa State University has developed a tool to determine what market conditions are needed for ethanol producers to make a profit. http://www.physorg.com/news151172429.html Other Sciences Wed, 14 Jan 2009 16:20:29 EST news151172429 Research led by Iowa State University scientists has them a step closer to finding a way to counter the Ebola virus. http://www.physorg.com/news150991288.html Biology Mon, 12 Jan 2009 14:01:28 EST news150991288 Iowa State University's Martin Pohl is part of a research team that has developed the first complete map of the Milky Way galaxy's spiral arms. The map shows the inner part of the Milky Way has two prominent, symmetric spiral arms, which extend into the outer galaxy where they branch into four spiral arms. http://www.physorg.com/news150365610.html Space & Earth Mon, 05 Jan 2009 08:13:30 EST news150365610
