The most comprehensive study to date of the proteins in a species of salamander that can regrow appendages may provide important clues to how similar regeneration could be induced in humans. http://www.physorg.com/news180013294.html Biology Mon, 14 Dec 2009 12:20:13 EST news180013294 (PhysOrg.com) -- Scientists have extracted organically preserved muscle tissue from an 18 million years old salamander fossil. The discovery by researchers from University College Dublin, the UK and Spain, reported in the Proceedings of the Royal Society B shows that soft tissue can be preserved under a broader set of fossil conditions than previously known. http://www.physorg.com/news176660912.html Other Sciences Thu, 05 Nov 2009 17:20:01 EST news176660912 (PhysOrg.com) -- A new study in the US and Canada has found that frogs can learn to associate the smell of predators with danger, even as embryos. http://www.physorg.com/news176453640.html Biology Tue, 03 Nov 2009 10:00:01 EST news176453640 (PhysOrg.com) -- Reptiles changed their walking posture from sprawling to upright immediately after the end-Permian mass extinction, the biggest crisis in the history of life that occurred some 250 million years ago and wiped out 90% of all species. http://www.physorg.com/news172221271.html Other Sciences Tue, 15 Sep 2009 08:15:10 EST news172221271 (PhysOrg.com) -- Researchers from the University of Georgia Warnell School of Forestry and Natural Resources weren`t looking for anything new when they went exploring in the northeast part of the state. But they ended up making a big discovery of a tiny animal, finding a new species of salamander that could change what scientists know about some amphibians. http://www.physorg.com/news166207786.html Biology Tue, 07 Jul 2009 17:50:06 EST news166207786 The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord -- even bits of lopped-off brain. But it turns out that remarkable ability isn't so mysterious after all -- suggesting that researchers could learn how to replicate it in people. http://www.physorg.com/news165674643.html Biology Wed, 01 Jul 2009 13:44:38 EST news165674643 When female tiger salamanders choose a mate, it turns out that size does matter - tail size that is - and that's not the only factor they weigh. http://www.physorg.com/news163692969.html Biology Mon, 08 Jun 2009 15:16:38 EST news163692969 Some dinosaurs may have held their heads up, like a giraffe, rather than in a more horizontal position, University of Portsmouth scientists report today. http://www.physorg.com/news162653613.html Other Sciences Wed, 27 May 2009 14:34:15 EST news162653613 Rare traits persist in a population because predators detect common forms of prey more easily. Researchers writing in the open access journal BMC Ecology found that birds will target salamanders that look like the majority - even reversing their behavior in response to alterations in the ratio of a distinguishing trait. http://www.physorg.com/news161360038.html Biology Tue, 12 May 2009 15:14:47 EST news161360038 (AP) -- The black salamander with yellow spots sat on the roadside in the dark, ready to make a go of it. http://www.physorg.com/news158223902.html Biology Mon, 06 Apr 2009 08:07:45 EST news158223902 Biologists analyzing DNA in search of the molecular underpinnings of life have consistently favored species with small genomes, which are cheaper to sequence and lack the repetitive "junk" that clutters bigger genomes. But a new study by Howard Hughes Medical Institute scientists suggests that when it comes to figuring out how genes are controlled, bigger genomes are much more useful. http://www.physorg.com/news155371512.html Biology Wed, 04 Mar 2009 06:46:08 EST news155371512 "FORE"...Though they may not help improve a person's golf game, stream salamanders might change the way golfers think about the local country club in the near future, following a new University of Missouri study. http://www.physorg.com/news147538622.html Biology Wed, 03 Dec 2008 14:57:02 EST news147538622 Although research has linked inbreeding with elevated rates of deformity in a wide variety of animals, a new study finds it plays no part in the high incidence of malformation among salamanders. http://www.physorg.com/news144422397.html Biology Tue, 28 Oct 2008 14:19:57 EST news144422397
