The reason: potential defects that cause the vehicles to speed up without warning and run out of control. The move follows a huge (and growing) recall of older Toyota vehicles last week. Safety Research and Strategies , based in Rehoboth, Mass., has reportedly implicated the sudden unintended acceleration problem to 2,274 incidents in Toyota vehicles, causing 275 crashes and at least 18 fatalities since 1999. <!-- <a href=http://www.scientificamerican.com/article.cfm?id=what-might-cause-a-gas-pe>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px;

In attempts to help heal the wounded tissue, some athletes, both amateur and professional, have turned to platelet-rich plasma (PRP) therapy. For the treatment, doctors take a small vial of a patient's blood, about 30 milliliters, and spin it in a centrifuge to separate the platelet-rich plasma from the other components.

In other words, just because some feature seems like a good idea, random mutation and selection will not necessarily fashion it.</p><p>Body parts that enable us to detect the sights, sounds, smells, tastes, temperature and tactile elements of our environment did not arise from some master plan or blueprint. Rather selection crafted body parts from available components of cells and tissues within existing forms of life, molding ancient and intermediate versions of sensory cells and organs--each elegant in its own right--like lumps of clay over aeons into the shape and form of our modern bodies. There have never been perfectly formed organs for sight or hearing--just versions that get the job done.</p> <a href=http://www.scientificamerican.com/article.cfm?id=evolved-eyes-back-of-head>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:65d3f6368a8a8625a64164acf6cd8541:yE2f1q3l23GFSfYlKQwQCLNq1T5KT1ivSlLJBW2QAXMDQ8%2BDUUBooJijW8CE9xGDZsiDTxnBwMV7'><img border='0' title='Add to digg' alt='Add to digg' src='http://images.pheedo.com/images/mm/digg.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:51138707e862ad6b0e9c1aeb94fefc95:SvNs%2BnGW9yeeYSDx97psUO74a%2Be8u4QzcjMOzKyF8VtMZgGWekr%2FxKMYa9tiPq9C3KV8%2FcEBumaFHg%3D%3D'><img border='0' title='Add to StumbleUpon' alt='Add to StumbleUpon' src='http://images.pheedo.com/images/mm/stumbleit.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:f305be271c5ace8b94182265ef42b33c:CoZ06SoYxzJAvxixcMa5rFQrYJpyUn%2BVZ2IqUf%2BZHt6BwGK%2FzB80hIc7FR73FYQ0JCLW4dmVH1un'><img border='0' title='Add to Reddit' alt='Add to Reddit' src='http://images.pheedo.com/images/mm/reddit.png'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:df9a1663f5f151aa21fd83b2bf4f3ea3:NvSIuq56iCbaqm%2F4xYlaVGSni7uXUkw5zvVQGrqErVgyUWplahZsrgDBCFDbwoW1wqVqkplqyd%2Fs%2FA%3D%3D'><img border='0' title='Add to Facebook' alt='Add to Facebook' src='http://images.pheedo.com/images/mm/facebook.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:542cf5091a1c39fa1db70052122700ca:LSzMGZ4227G1Kqd8XQTwkt4d5p3OM76sbVrWlqVleT2ww2qVzXd36rFg58I3Q1FsNV3Es30oH4YU'><img border='0' title='Add to del.icio.us' alt='Add to del.icio.us' src='http://images.pheedo.com/images/mm/delicious.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:6fbc766b7b6842cf35d591da46beaecd:eE%2BZjClmEHaR8h9O3zZ5KVZkqNtCcX4fCkpjWU7sCTHwu4OmC8KixgiMxXqpCq%2FQX382lhoN7aUP'><img border='0' title='Email this Article' alt='Email this Article' src='http://images.pheedo.com/images/mm/emailthis.png'/></a> <br clear="both" style="clear: both;"/> <a href="http://ads.pheedo.com/click.phdo?s=68cbfab30b905b003ee6d4f61206fcc8&p=1"><img alt="" style="border: 0;" border="0" src="http://ads.pheedo.com/img.phdo?s=68cbfab30b905b003ee6d4f61206fcc8&p=1"/></a> <img alt="" height="0" width="0" border="0" style="display:none" src="http://a.rfihub.com/eus.gif?eui=2223"/> Biology,Health & Medicine,Space,Everyday Science,Basic Science,Basic Science,Evolution Thu, 02 Jul 2009 08:00:00 EST http://rss.sciam.com/click.phdo?i=2d7446f380d113f009a439eb08c01bee http://www.scientificamerican.com/article.cfm?id=how-do-stress-fractures-develop <p>Considering the forces involved in many sports, it's no surprise that professional athletes sustain serious injuries to their muscles, ligaments, tendons and bones. A spate of bone fracture&ndash;related injuries seems to be dogging professional teams this year. The Houston Rockets of the National Basketball Association lost seven-time all-star Tracy McGrady to season-ending microfracture surgery in February. And on Monday, Rocket&rsquo;s team physician Tom Clanton announced in the Houston Chronicle that all-star center Yao Ming's fractured foot, which he sustained in a play-off game against the Los Angeles Lakers in May, has worsened over time and may end his career. The possibility that New York Mets centerfielder Carlos Beltran might have a microfractured knee turned fans and fantasy baseball owners into nervous wrecks. Such an injury ended the career of NBA star Jamal Mashburn.</p><p>So how do these fractures develop? And why can they have such impact on athletes' careers, in some cases forcing players into early retirement? To find out, we turned to Howard Palamarchuk , a former Olympic-class race walker who is the director of sports medicine at Temple University School of Podiatric Medicine.</p> <a href=http://www.scientificamerican.com/article.cfm?id=how-do-stress-fractures-develop>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:be504396111cd7716fdea34357a850d4:UmuB2zK3EPd9IuZR91nob%2BWL%2BGjbrzQ2hF704caI4zsTYMQ5Kj%2BEQuWWuF2ysi3k9D5Sd10RKitq'><img border='0' title='Add to digg' alt='Add to digg' src='http://images.pheedo.com/images/mm/digg.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:df2993f62624388d8d9d08454538eadb:yp2EsKG9amcJyiYSp4EBc5RWu6c8v31DT9xhKrAnrUOifsgGXwDN7W4QHrKS1mIUWY0fMJXYR7AgJA%3D%3D'><img border='0' title='Add to StumbleUpon' alt='Add to StumbleUpon' src='http://images.pheedo.com/images/mm/stumbleit.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:1b24f94d6cf4c48d94f22d9d455b23cd:Trx8oOZkyFFQrO%2BgyGJu6%2By7SiTxB%2FyPqSKHggJgxk0A%2BEQLr4Tr1a5q1ODOGGhIe2C1GFzxSUSS'><img border='0' title='Add to Reddit' alt='Add to Reddit' src='http://images.pheedo.com/images/mm/reddit.png'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:056b2d2b6a2ecd3bab54c0b87ab87c0c:F9ONZU86ny7xGjCyTPCSFBdQHsszNDRB5iwQfUnlxV1mg%2BGrVtVkiqVCsO%2BVp%2F2PHxux1sTUBUHWlA%3D%3D'><img border='0' title='Add to Facebook' alt='Add to Facebook' src='http://images.pheedo.com/images/mm/facebook.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:9b890c0fbf231bed801938e06d9ae15d:WkgkxUQ4eg3ANbQzymAs%2FFifDmyLyUDhx55GXw%2FTKa5PDBTA023EkDd4y%2BAh6J1XFWVeVwfJMplY'><img border='0' title='Add to del.icio.us' alt='Add to del.icio.us' src='http://images.pheedo.com/images/mm/delicious.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:8feb1149c2fd8ca17c294f48b972774d:X%2BBlInBHO7S0sqNIqHYrdKyKGAVE5SfA%2F15vLe8VsG%2FCqtN90%2BoEsZWXmRSTV%2BNWoUAJNFnk1tCL'><img border='0' title='Email this Article' alt='Email this Article' src='http://images.pheedo.com/images/mm/emailthis.png'/></a> <br clear="both" style="clear: both;"/> <a href="http://ads.pheedo.com/click.phdo?s=2d7446f380d113f009a439eb08c01bee&p=1"><img alt="" style="border: 0;" border="0" src="http://ads.pheedo.com/img.phdo?s=2d7446f380d113f009a439eb08c01bee&p=1"/></a> <img alt="" height="0" width="0" border="0" style="display:none" src="http://a.rfihub.com/eus.gif?eui=2223"/> Biology,Health & Medicine,Space,Basic Science,Evolution Mon, 29 Jun 2009 13:38:00 EST http://rss.sciam.com/click.phdo?i=5970876315fc10fbe8bfcc57d467320c http://www.scientificamerican.com/article.cfm?id=geothermal-drilling-earthquakes <p>Despite the promise of cheap, clean power, geothermal energy development may be on shaky ground.
