Earlier studies have shown that the bears are swimming hundreds of miles to reach solid ice or land, but a new study demonstrates that the longer swims increase cub mortality, compared with cubs that didn&#39;t swim such long distances. According to Reuters:</p> <p class="rteindent1"> <span style="background-color:#d3d3d3;">&quot;Climate change is pulling the sea ice out from under polar bears&#39; feet, forcing some to swim longer distances to find food and habitat,&quot; said Geoff York of World Wildlife Fund, a co-author of the study.</span></p> <p> Between 2004 and 2009, a team of researchers led by Anthony Pagano of the U.S. Geological Survey gathered data from 68 GPS collars that had been put on adult female polar bears, and looked at that data along with satellite imagery of sea ice, in order to isolate episodes where bears swam more than 30 miles at one time, according to a <a href="">synopsis of the research</a> on PRWeb. (The final report is not yet released but the full abstract is provided with the synopsis at PRWeb.) Researchers identified 50 long-distance swimming events, involving 20 polar bears, over the six years. The bears swam distances of as far as 426 miles, and as many as 12.7 days.</p> <p> Eleven of the polar bears that swam the long distances had young cubs at the time that they were collared; five of those bears lost their cubs during the swims, which translated to a 45 percent morality rate. Only 18 percent of cubs died when they weren&#39;t swimming the long distances with their mothers.</p> <p> A big difference.</p> <p> The long-distance swims <a href="">took a toll</a> on the cubs partially because young polar bears don&#39;t have much fat and thus can&#39;t be in the cold water for long periods of time, Time said. Steve Amstrup, a former scientist at the U.S. Geological Survey and chief scientist at the conservation group Polar Bears International, said, according to Reuters:</p> <p class="rteindent1"> <span style="background-color:#d3d3d3;">&quot;Young bears don&#39;t have very much fat and therefore they aren&#39;t very well insulated and cannot cope with being in cold water for very long,&quot; Amstrup said in the same telephone conversation.</span></p> <p class="rteindent1"> <span style="background-color:#d3d3d3;">Because they are leaner than their parents, Amstrup said, &quot;they probably aren&#39;t as buoyant (as adult polar bears) so in rough water they&#39;ll have more difficulty keeping their heads above water.</span></p> <p> Evidence that long-distance swimming <a href="">takes a toll</a> on polar bears was already presented in a study published earlier this year that tracked a polar bear mother that swam for 232 consecutive hours in search of pack ice, and lost 22 percent of her body mass as a result, while her <a href="">cub lost its life</a>, Discovery reported. And in 2006, researchers came to the conclusion that an apparent rise in the number of <a href="">polar bears found drowned</a> could be linked to the bears being forced to swim longer distances.</p> <p><a href="" target="_blank">read more</a></p> Arctic Climate Change Global Warming Science Business Wildlife News Science Weird Wide Web Wed, 20 Jul 2011 05:04:00 +0000 News Desk 5670980 at Mission complete: U.S. shuttle Atlantis lands for last time <p> The world&#39;s astronauts will now have to rely on Russian Soyuz rockets for any trips to the International Space Station</p> <p><a href="" target="_blank">read more</a></p> Science Space Science United States Thu, 21 Jul 2011 11:49:00 +0000 News Desk 5671087 at Ecstasy trials in UK to 'benefit trauma victims' <!--paging_filter--><p> Traumatized survivors of rape, <a href="">child abuse </a>and war could be treated with the clubbing drug ecstasy, if new medical trials are successful.</p> <p> Doctors in the UK are planning the first clinical trial of ecstasy to see if it has any therapeutic value in enabling people to overcome long-held feelings of distress.</p> <p><a href="" target="_blank">read more</a></p> Drugs Science Europe United Kingdom Sat, 01 Oct 2011 12:30:00 +0000 News Desk 5676595 at Spermless mosquitoes offer new disease hope <p> The genetically modified males, released back in 1999 in a dengue-affected part of the Cayman Islands, were able to mate successfully with wild females.</p> <p><a href="" target="_blank">read more</a></p> Science Education Health United Kingdom Mon, 31 Oct 2011 10:05:00 +0000 News Desk 5679710 at Stephen Hawking misses 70th birthday celebrations due to illness <p> The title of Hawking&#39;s lecture, &ldquo;A Brief History of Mine&rdquo;, is a play on his first book, &ldquo;A Brief History of Time&rdquo;, which has sold more than 10 million copies internationally and brought complex scientific ideas to a wider audience.<br /> &nbsp;</p> <p><a href="" target="_blank">read more</a></p> Science Business Science Sun, 08 Jan 2012 15:10:00 +0000 Luke Browne 5686365 at Patient gets a new jaw from 3D printer An 83-year-old woman has a new jaw made from titanium powder, constructed one layer at a time by a laser. <p><a href="" target="_blank">read more</a></p> Belgium Health Science Technology news Business Europe Innovation Science Technology Weird Wide Web Mon, 06 Feb 2012 19:17:00 +0000 Amy Silverstein 5690584 at French judge says Monsanto poisoned farmer It was the first case of its kind in France and could pave the way for other pesticide-related lawsuits. <p><a href="" target="_blank">read more</a></p> France Green Health Science United States Business Green France Europe Health Tue, 14 Feb 2012 18:37:00 +0000 Amy Silverstein 5691659 at Scientists discover that goats develop 'accents' Just like humans, goats can develop accents too, say scientists in a report released Thursday.<p><a href="" target="_blank">read more</a></p> animals Science Wildlife News Fri, 17 Feb 2012 01:51:00 +0000 Alexander Besant 5692149 at Scientists grow plant from 30,000-year-old fruit A team of Russian scientists announced that they had succeeded in growing a plant from a fruit stored away by squirrels in permafrost over 30,000 years ago.<p><a href="" target="_blank">read more</a></p> Science Science Mon, 20 Feb 2012 23:58:00 +0000 Alexander Besant 5692587 at Scientists claim to find the deepest dwelling land animal in a cave <p> A team of European researchers searching for life inside the earth, discovered what could be the world&#39;s deepest dwelling land animal.</p> <p><a href="" target="_blank">read more</a></p> animals Science Science Wed, 22 Feb 2012 23:47:46 +0000 Alexander Besant 5693031 at Migrating birds not adjusting to climate change, study says Some types of birds on the East Coast of North America are adjusting their migration patterns in order to adjust to climate change.<p><a href="" target="_blank">read more</a></p> Science Science Fri, 24 Feb 2012 00:09:30 +0000 Alexander Besant 5693235 at
