However, this does not necessarily have to be the case. Last week, a group of engineering students set a land speed record for a vehicle powered by hydrogen fuels cells. The car that was able to break 300 mph is the Buckeye Bullet 2. http://www.physorg.com/news173365419.html Technology Mon, 28 Sep 2009 14:04:09 EST news173365419 (PhysOrg.com) -- Chinese scientists today reveal the discovery of five remarkable new feathered dinosaur fossils which are significantly older than any previously reported.

Elongated fingers, an opposable "thumb," and a grasping tail of Suminia getmanovi demonstrate that this small plant-eating synapsid is the earliest known tree-climbing vertebrate http://www.physorg.com/news168072751.html Other Sciences Wed, 29 Jul 2009 10:00:01 EST news168072751 Hungry, sexual organisms replaced well-fed, clonal organisms in the Caribbean Sea as the Isthmus of Panama arose, separating the Caribbean from the Pacific, report researchers from the Smithsonian Tropical Research Institute and Scripps Institution of Oceanography. The fossil record shows that if a species could shift from clonal to sexual reproduction it survived. Otherwise it was destined for extinction, millions of years later. http://www.physorg.com/news168072386.html Biology Wed, 29 Jul 2009 08:50:02 EST news168072386 (PhysOrg.com) -- People who illegally download music, films and TV episodes do not believe they are doing anything wrong, said a Queensland University of Technology researcher. http://www.physorg.com/news167052716.html Other Sciences Fri, 17 Jul 2009 12:33:34 EST news167052716 While watching swimmers line up during the 2008 Olympic Games in Beijing, former Olympic swimmer and NBC Sports commentator Rowdy Gaines quipped that swimmers keep getting bigger, with the shortest one in the current race towering over the average spectator. http://www.physorg.com/news167027175.html Medicine & Health Fri, 17 Jul 2009 05:28:42 EST news167027175 (PhysOrg.com) -- Taller men are able to earn more money than their shorter counterparts simply because taller people are perceived to be more intelligent and powerful, this according to a study published in The Economic Record by Wiley-Blackwell. http://www.physorg.com/news166721834.html Other Sciences Mon, 13 Jul 2009 16:37:32 EST news166721834 New evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous - a period of greenhouse conditions - gives a glimpse of how the Arctic is likely to respond to future global warming. http://www.physorg.com/news166355359.html Space & Earth Thu, 09 Jul 2009 10:49:50 EST news166355359 (AP) -- Universal Music Group's distribution arm is teaming up with digital track distributor TuneCore, a move it says will give it a leg up in signing up-and-coming artists without a recording deal yet. http://www.physorg.com/news166337532.html Technology Thu, 09 Jul 2009 06:20:03 EST news166337532 Boston Medical Center (BMC) researchers have identified potential safety risks among methadone maintenance treatment (MMT) patients due to the quantity and accuracy of medical record documentation.

They found that only 61.9 percent of patients assigned a billing diagnosis code for Barrett's esophagus actually had Barrett's esophagus after a manual record review. The study evaluated the accuracy of diagnostic codes for Barrett's esophagus by contrasting codes from electronic databases with diagnoses from a detailed medical record review. Researchers also evaluated the reproducibility of a pathologic diagnosis of Barrett's esophagus between two pathologists and between a single pathologist on two different occasions. The study appears in the May issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE). http://www.physorg.com/news161530388.html Medicine & Health Thu, 14 May 2009 14:34:04 EST news161530388 (PhysOrg.com) -- Security researchers have uncovered one of the most notorious zombie networks, the Torpig botnet, by collecting 70GB of data that was stolen in just 10 days. http://www.physorg.com/news160749834.html Technology Tue, 05 May 2009 13:44:23 EST news160749834 (PhysOrg.com) -- Were major extinction events real biological catastrophes or were they merely the result of gaps in the fossil record? Research by a team of geologists from the Universities of Bristol, Plymouth, and Saratov State in Russia, has shed new light on a debate that has divided scientists of late and was recognised as far back as Darwin`s Origin of Species. http://www.physorg.com/news160663448.html Space & Earth Mon, 04 May 2009 13:44:41 EST news160663448 A new paper published in the latest issue of the open access publication Journal of Medical Internet Research evaluates consumers' experiences with the Indivo personally controlled health record (PCHR) system - a system developed by researchers in the Children's Hospital Informatics Program (CHIP) more than a decade ago that has been adapted by PCHR providers including Dossia, Microsoft and Google. This is the first report to be published that investigates consumers' response to a platform PCHR and subsequent implications for policy and design. http://www.physorg.com/news160389561.html Medicine & Health Fri, 01 May 2009 09:39:43 EST news160389561
