(PhysOrg.com) -- Despite being a founding principle of modern biology for 150 years, evolutionary theory has played a limited role in the field of medicine. Only in the last 20 years has Darwinian medicine emerged as a discipline unto itself. An article in this month`s issue of The Quarterly Review of Biology explains why early attempts to study disease from an evolutionary perspective failed, and how modern Darwinian medicine differs from its antecedent. http://www.physorg.com/news179686563.html Biology Thu, 10 Dec 2009 17:19:48 EST news179686563 (PhysOrg.com) -- What, exactly, distinguishes humans from apes? It`s certainly more than just our genes, renowned anthropologist Sarah Blaffer Hrdy told a Harvard audience recently (Nov. 18). http://www.physorg.com/news178820796.html Biology Mon, 30 Nov 2009 22:30:01 EST news178820796 Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease. Using statistical analysis on skeletal remains of a well-preserved female specimen, researchers determined the "hobbit" to be a distinct species and not a genetically flawed version of modern humans. Details of the study appear in the December issue of Significance, the magazine of the Royal Statistical Society. http://www.physorg.com/news177828426.html Other Sciences Thu, 19 Nov 2009 04:48:32 EST news177828426 (AP) -- Ryan Norwalk has cleared his schedule.

Names like Antoine Lavoisier, John Dalton, and Amadeo Avogadro may even bring a twinkle of recognition to the eye for their famous roles in establishing chemistry as a modern science. http://www.physorg.com/news169703985.html Other Sciences Mon, 17 Aug 2009 05:00:06 EST news169703985 (PhysOrg.com) -- Electronic gadgetry gets tinier and more powerful all the time, but at some point, the transistors and myriad other component parts will get so little they won't work. That's because when things get really small, the regular rules of Newtonian physics quit and the weird rules of quantum mechanics kick in. When that happens, as physics professor and chair Ravindra Pandey puts it, "everything goes haywire." http://www.physorg.com/news169397882.html Nanotechnology Thu, 13 Aug 2009 15:58:43 EST news169397882 (PhysOrg.com) -- Evidence that early modern humans living on the coast of the far southern tip of Africa 72,000 years ago employed pyrotechnology - the controlled use of fire - to increase the quality and efficiency of their stone tool manufacturing process, is being reported in the Aug. 14 issue of the journal Science. An international team of researchers, including three from the Institute of Human Origins at Arizona State University, deduce that "this technology required a novel association between fire, its heat, and a structural change in stone with consequent flaking benefits." Further, their findings ignite the notion of complex cognition in these early engineers. http://www.physorg.com/news169391684.html Other Sciences Thu, 13 Aug 2009 14:16:19 EST news169391684 Spanish researchers say they're a step closer to resolving a "mystery of evolution" -- why some people like Brussels sprouts but others hate them. http://www.physorg.com/news169297576.html Other Sciences Wed, 12 Aug 2009 12:07:29 EST news169297576 Stable isotope data published this week in the Proceedings of the National Academy of Sciences by Erik Trinkaus, professor of anthropology at Washington University in St. Louis, and Michael Richards of the University of British Columbia and the Max Planck Institute, suggests that at least some of the European early modern humans consistently consumed fish, supplementing their diet of terrestrial animals. http://www.physorg.com/news169187809.html Other Sciences Tue, 11 Aug 2009 06:00:02 EST news169187809 (PhysOrg.com) -- African village dogs are not a mixture of modern breeds but have directly descended from an ancestral pool of indigenous dogs, according to a Cornell-led genetic analysis of hundreds of semi-feral village dogs. http://www.physorg.com/news168619238.html Biology Tue, 04 Aug 2009 15:41:07 EST news168619238 (PhysOrg.com) -- Inside a mountain range in central Italy, Columbia researchers are trying to solve one of the most pressing questions in modern physics: What is dark matter? The riddle has obsessed astronomers and physicists since the 1930s, when Caltech professor Fritz Zwicky first predicted its existence. Because dark matter neither emits nor reflects light and cannot be directly observed, no one has ever proven that it exists; yet theories show it makes up as much as a quarter of the universe. Columbia physics professor Elena Aprile, with collaborators from universities around the world, including Rice University and UCLA, is leading the race to find and identify dark matter for the first time. http://www.physorg.com/news167927738.html Physics Mon, 27 Jul 2009 15:36:47 EST news167927738 The National Gallery in London will exhibit a collection of fake and wrongly-attributed paintings next year, in a show exploring how modern science has lifted the lid on centuries of forgery. http://www.physorg.com/news167460774.html Other Sciences Wed, 22 Jul 2009 09:00:03 EST news167460774 (PhysOrg.com) -- The wound that ultimately killed a Neandertal man between 50,000 and 75,000 years was most likely caused by a thrown spear, the kind modern humans used but Neandertals did not, according to Duke University-led research. http://www.physorg.com/news167323513.html Other Sciences Mon, 20 Jul 2009 16:30:01 EST news167323513 Excavations in the summer of 2008 at the sites of Hohle Fels and Vogelherd produced new evidence for Paleolithic music in the form of the remains of one nearly complete bone flute and isolated small fragments of three ivory flutes. http://www.physorg.com/news165069257.html Other Sciences Wed, 24 Jun 2009 15:40:02 EST news165069257 Increasing population density, rather than boosts in human brain power, appears to have catalysed the emergence of modern human behaviour, according to a new study by UCL (University College London) scientists published in the journal Science. High population density leads to greater exchange of ideas and skills and prevents the loss of new innovations. It is this skill maintenance, combined with a greater probability of useful innovations, that led to modern human behaviour appearing at different times in different parts of the world. http://www.physorg.com/news163344562.html Other Sciences Thu, 04 Jun 2009 14:29:59 EST news163344562 Modern humans may have eaten Neanderthals, scientists report in the Journal of Anthropological Sciences this month. http://www.physorg.com/news161876049.html Other Sciences Mon, 18 May 2009 14:34:50 EST news161876049 (PhysOrg.com) -- For the first time in nearly 500 years, a full-size balsa-wood raft just like those used in pre-Columbian Pacific trade took to the water on Sunday, May 10. Only this time, instead of the Pacific coast between Mexico and Chile where such rafts carried goods between the great civilizations of the Andes and Mesoamerica as long as a millennium ago, the replica raft was floated in the Charles River basin. http://www.physorg.com/news161446493.html Other Sciences Wed, 13 May 2009 15:19:05 EST news161446493 A detailed analysis of the feet of Homo floresiensis -the miniature hominins who lived on a remote island in eastern Indonesia until 18,000 years ago -- may help settle a question hotly debated among paleontologists: how similar was this population to modern humans? A new research paper, featured on the cover of the current issue of Nature, may answer this question. While the so-called "hobbits" walked on two legs, several features of their feet were so primitive that their gait was not efficient. http://www.physorg.com/news160834618.html Other Sciences Wed, 06 May 2009 13:17:29 EST news160834618 You fall off your bike and break your collarbone, and your doctor tells you to stay off the bike for six to eight weeks.

DeSilva an anthropologist at Worcester University in Massachusetts has published "Functional Morphology of the Ankle and the Likelihood of Climbing in Early Hominins," in the peer-reviewed journal, Proceeding of the National Academies of Sciences of the USA current issue. The study includes data gathered by DeSilva in Uganda's Kibale National Park of modern chimpanzee and comparisons of hominin fossil skeletal remains dating back some 4.12 million to 1.53 million years ago. The findings appear to show that if early hominins depended on tree climbing as part of their survival repertoire, they were performing it decidedly different from modern chimpanzee locomotor activity. http://www.physorg.com/news159038272.html Biology Wed, 15 Apr 2009 18:18:32 EST news159038272 Dazzling new scientific techniques are allowing archaeologists to track the movements and menus of extinct hominids through the seasons and years as they ate their way across the African landscape, helping to illuminate the evolution of human diets. http://www.physorg.com/news153674920.html Other Sciences Thu, 12 Feb 2009 15:29:29 EST news153674920 In a development which could reveal the links between modern humans and their prehistoric cousins, scientists said Thursday they have mapped a first draft of the Neanderthal genome. Researchers used DNA fragments extracted from three Croatian fossils to map out more than 60 percent of the entire Neanderthal genome by sequencing three billion bases of DNA. http://www.physorg.com/news153656986.html Biology Thu, 12 Feb 2009 10:30:13 EST news153656986 (PhysOrg.com) -- A Livermore researcher who teamed with a United Kingdom collaborator has published an article in Reviews of Modern Physics that refines decades of actinide science and may just become the preeminent research paper in the field. http://www.physorg.com/news153596330.html Physics Wed, 11 Feb 2009 17:39:33 EST news153596330 (PhysOrg.com) -- A new study of the skeletal fossils of Neanderthal and Early modern man suggest the lack of a "throwing arm" may have made the difference in human evolution. Researchers Jill A. Rhodes and Steven Churchill, evolutionary anthropologists published their findings in the January 2009 edition of the Journal of Human Evolution. The paper entitled, "Throwing in the Middle and Upper Paleolithic: inferences from an analysis of humeral retroversion," provides some clues to the extinction of Neanderthal. http://www.physorg.com/news151326825.html Other Sciences Fri, 16 Jan 2009 11:13:45 EST news151326825 The earliest known bird, the magpie-sized Archaeopteryx, had a similar hearing range to the modern emu, which suggests that the 145 million-year-old creature - despite its reptilian teeth and long tail - was more birdlike than reptilian, according to new research published today. http://www.physorg.com/news151139884.html Other Sciences Wed, 14 Jan 2009 07:18:04 EST news151139884 (PhysOrg.com) -- Highly dispersed and mobile teams are the definition of modern business, but organising them is a hard problem.
