(PhysOrg.com) -- A find of 60 headless skeletons summer 2009 may reveal the identity of the people who first inhabited the Pacific Ocean archipelago Vanuatu 3000 years ago. http://www.physorg.com/news180636268.html Other Sciences Mon, 21 Dec 2009 17:01:02 EST news180636268 The research that brought to light the fossils of Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia, has topped Science's list of this year's most significant scientific breakthroughs. The monumental find predates "Lucy," -- previously the most ancient partial skeleton of a hominid on record -- by more than one million years, and it inches researchers ever-closer to the last common ancestor shared by humans and chimpanzees. http://www.physorg.com/news180282874.html Other Sciences Thu, 17 Dec 2009 14:35:25 EST news180282874 (PhysOrg.com) -- The Early Cretaceous sauropod Paluxysaurus jonesi weighed 20 tons, was 60 feet long and had a neck 26 feet long, according to scientists who prepared the world's first full skeletal mount of the dinosaur. http://www.physorg.com/news180109544.html Other Sciences Tue, 15 Dec 2009 14:28:01 EST news180109544 Three University of Alberta paleontology graduate students blew the dust off an 85-year-old dinosaur find to discover the original researcher had it right and a 1970s revision of his work was wrong. http://www.physorg.com/news180034956.html Other Sciences Mon, 14 Dec 2009 18:00:23 EST news180034956 (AP) -- The skeleton of a Tyrannosaurus rex will make its museum debut at the Oregon Museum of Science and Industry along the banks of the Willamette River. http://www.physorg.com/news179737739.html Other Sciences Fri, 11 Dec 2009 07:10:42 EST news179737739 Did the first dinosaurs wander across continents or stay put where they first evolved? The first dinosaurs evolved 230 million years ago when the continents were assembled into one landmass called Pangea. The question of early dinosaur movements remained unclear until the discovery of some exciting new fossils. http://www.physorg.com/news179677942.html Other Sciences Thu, 10 Dec 2009 15:00:02 EST news179677942 (AP) -- Scientists say they've discovered a new dinosaur species in South Africa that may help explain how the creatures evolved into the largest animals on land. http://www.physorg.com/news177154893.html Other Sciences Wed, 11 Nov 2009 09:41:56 EST news177154893 We all know adolescents get testy from time to time.

During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first segments to be added become the vertebrae of the neck, later segments become the vertebrae with ribs and the last ones the vertebra located in the tail (in the case of a mouse, for example). In this process, it is crucial that, on the one hand, each segment, as it matures, becomes the correct type of vertebra and, on the other, that the number of vertebrae in the skeleton, and therefore the size of the spine, are minutely controlled. http://www.physorg.com/news175861637.html Medicine & Health Tue, 27 Oct 2009 11:40:01 EST news175861637 Sucked to her death in a muddy river bed, a baby woolly mammoth spent 40,000 years frozen in the Siberian permafrost where her body was so perfectly preserved traces of her mother's milk remained in her belly. http://www.physorg.com/news173841145.html Other Sciences Sun, 04 Oct 2009 02:13:49 EST news173841145 In a special issue of Science, an international team of scientists has for the first time thoroughly described Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia.

Researchers at the University of Gothenburg, Sweden, have discovered previously unknown species that feed only on dead whales - and use DNA technology to show that the species diversity in our oceans may be higher than previously thought. http://www.physorg.com/news172739527.html Biology Mon, 21 Sep 2009 08:30:01 EST news172739527 A skeleton, found at one of the most important, but least understood, Roman sites in Britain is puzzling experts from The University of Nottingham. http://www.physorg.com/news172234674.html Other Sciences Tue, 15 Sep 2009 11:58:29 EST news172234674 (AP) -- Museums and high-rolling natural history buffs will get a crack at buying a fossilized Tyrannosaurus rex next month at a Las Vegas Strip auction. http://www.physorg.com/news171306818.html Other Sciences Fri, 04 Sep 2009 18:14:01 EST news171306818 We still have a lot to discover about the mechanism in plants that ensures cell growth in a specific direction. However it is clear that a structure of parallel protein tubes plays an important role. Simon Tindemans investigated this structure during his doctoral research at the FOM Institute for Atomic and Molecular Physics, The Netherlands. According to him small 'catastrophic collisions' are a crucial part of the process leading to its creation. http://www.physorg.com/news171136989.html Biology Wed, 02 Sep 2009 22:40:01 EST news171136989 A rare Tyrannosaurus Rex skeleton, among the most complete specimens in the world, is to go on the auction block in Las Vegas in October, the auction house Bonhams & Butterfields has said. http://www.physorg.com/news169384657.html Other Sciences Thu, 13 Aug 2009 12:18:04 EST news169384657 (PhysOrg.com) -- The accepted dogma has been that bone-forming cells, derived from the body's connective tissue, are the only cells able to form the skeleton. However, new research shows that specialized cells in the blood share a common origin with white blood cells derived from the bone marrow and that these bloodstream cells are capable of forming bone at sites distant from the original skeleton. This work, published online this month in the journal Stem Cells, represents the first example of how circulating cells may contribute to abnormal bone formation. http://www.physorg.com/news167579675.html Medicine & Health Thu, 23 Jul 2009 14:55:07 EST news167579675 (AP) -- Archaeologists have discovered a water well in Cyprus that was built as long as 10,500 years ago, and the skeleton of a young woman at the bottom of it, an official said Wednesday. http://www.physorg.com/news165070153.html Other Sciences Wed, 24 Jun 2009 14:50:02 EST news165070153 (AP) -- Indonesian scientists are reconstructing the largest, most complete skeleton of a prehistoric giant elephant ever found in the tropics, a finding that may offer new clues into the largely mysterious origins of its modern Asian cousin. http://www.physorg.com/news164957722.html Other Sciences Tue, 23 Jun 2009 06:36:29 EST news164957722 A finely preserved skeleton of a mammoth, believed to be one million years old, was uncovered near an archaeological site in eastern Serbia, local media reported on Wednesday. http://www.physorg.com/news163257405.html Other Sciences Wed, 03 Jun 2009 14:17:13 EST news163257405 (PhysOrg.com) -- A 47-million-year-old primate fossil, a purported "missing link" between primates and humans, was unveiled this week in New York. The fossil, formally called Darwinius masillae but nicknamed Ida, could, due to it being an essentially whole skeleton, shed light on the construction of the primate family tree, says an expert on primate evolution at Washington University in St. Louis. http://www.physorg.com/news161954864.html Other Sciences Tue, 19 May 2009 13:27:10 EST news161954864 The advice and treatment given to patients with vertebral compression fractures is not satisfactory. A thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden, shows that the majority of patients still have severe pain one year after the fracture. http://www.physorg.com/news159700955.html Medicine & Health Thu, 23 Apr 2009 10:23:18 EST news159700955 (PhysOrg.com) -- Researchers from the United States and Canada have found a fossil skeleton of a newly discovered carnivorous animal, Puijila darwini. New research suggests Puijila is a "missing link" in the evolution of the group that today includes seals, sea lions, and the walrus. The analysis of the skeleton and support for the hypotheses that pinniped origins can be found in the Arctic will be described in the April 23 issue of the journal Nature. http://www.physorg.com/news159625083.html Other Sciences Wed, 22 Apr 2009 13:18:27 EST news159625083 The bacterium Escherichia coli is part of the healthy human intestinal flora. However, E. coli also has pathogenic relatives that trigger diarrhea illnesses: enterohemorrhagic E.coli bacteria. During the course of an infection they infest the intestinal mucosa, causing injury in the process, in contrast to benign bacteria. http://www.physorg.com/news156686308.html Biology Thu, 19 Mar 2009 13:02:20 EST news156686308 New finds of 95 million year old fossils reveal much earlier origins of modern octopuses. These are among the rarest and unlikeliest of fossils. The chances of an octopus corpse surviving long enough to be fossilized are so small that prior to this discovery only a single fossil species was known, and from fewer specimens than octopuses have legs. http://www.physorg.com/news156513035.html Other Sciences Tue, 17 Mar 2009 12:51:25 EST news156513035 (PhysOrg.com) -- The laser light glowed brilliant red, forming a moving line as it bounced information from the dodo`s bones back into the high-tech scanner sitting on a tripod on the Museum of Comparative Zoology`s (MCZ) fifth floor. http://www.physorg.com/news154359318.html Other Sciences Fri, 20 Feb 2009 13:36:39 EST news154359318 (PhysOrg.com) -- In the Mesozoic Era, 70 million years before birds first conquered the skies, pterosaurs dominated the air with sparrow- to Cessna-sized wingspans. Researchers suspected that these extinct reptiles sustained flight through flapping, based on fossil evidence from the wings, but had little understanding of how pterosaurs met the energetic demands of active flight. http://www.physorg.com/news154161897.html Other Sciences Wed, 18 Feb 2009 06:45:42 EST news154161897 In an article in today's Nature, Uppsala researcher Martin Brazeau describes the skull and jaws of a fish that lived about 410 million years ago. The study may give important clues to the origin of jawed vertebrates, and thus ultimately our own evolution. http://www.physorg.com/news151235468.html Other Sciences Thu, 15 Jan 2009 09:51:08 EST news151235468 The skeleton of a man discovered by archaeologists in a shallow grave on the site of the University of York's campus expansion could be that of one of Britain's earliest victims of tuberculosis.
