He cited discoveries of microbes eking out existence in steaming hot springs in Yellowstone, in an acidic environment in Rio Tinto, Spain, and other hostile locations. &ldquo;Even in rocks, there&rsquo;s life,&rdquo; he added, showing the audience an image of a green streak tenaciously spreading through rock. &ldquo;Once life gets started, it can adapt and colonize many, many different environments.&rdquo; In addition, astronomers have found hundreds of  planets in other solar systems , and the space-based  Kepler telescope  recently identified more than 700 more candidate exoplanets. Many of those could have Earth-like conditions, raising the possibility that they also could harbor some form of life. How common might life be? &ldquo;The question is: Is it easy or hard to make the transition in the chemistry of planets from not alive to alive?&rdquo; asked Szostak.</p> <a href=http://www.scientificamerican.com/blog/post.cfm?id=how-did-life-begin-on-earth-2010-06-29>[More]</a><br clear="both" style="clear: both;"/>

Here we provide the surprising origins of some strange and familiar things.</p><p> All In The Family   <a href=http://www.scientificamerican.com/article.cfm?id=origins-aug-2010>[More]</a><br clear="both" style="clear: both;"/>

Scientists may be zeroing in on that most profound of questions. &ldquo;We&rsquo;ve gone a long way to showing&rdquo; the processes that &ldquo;set the stage&rdquo; for cellular life on Earth, Jack Szostak said Tuesday here in his talk at the 60th annual  Nobel Laureate  Lectures at Lindau .</p><p>Recent findings--such as that life seems to be everywhere on Earth--have encouraged scientific inquiries into the nature of life&rsquo;s beginnings, said Szostak. Along with Elizabeth H. Blackburn and Carol W. Greider, Szostak won the  2009 Nobel Prize in Physiology or Medicine  for work in understanding telomeres [see Blackburn and Greider's  Scientific American  article  &ldquo;  Telomeres, Telomerase and Cancer  &rdquo;]. His talk focused on his recent research on life&rsquo;s start [see his  Scientific American   2009 article, &ldquo; The Origin of Life on Earth &rdquo;]. He cited discoveries of microbes eking out existence in steaming hot springs in Yellowstone, in an acidic environment in Rio Tinto, Spain, and other hostile locations. &ldquo;Even in rocks, there&rsquo;s life,&rdquo; he added, showing the audience an image of a green streak tenaciously spreading through rock. &ldquo;Once life gets started, it can adapt and colonize many, many different environments.&rdquo; In addition, astronomers have found hundreds of  planets in other solar systems , and the space-based  Kepler telescope  recently identified more than 700 more candidate exoplanets. Many of those could have Earth-like conditions, raising the possibility that they also could harbor some form of life. How common might life be? &ldquo;The question is: Is it easy or hard to make the transition in the chemistry of planets from not alive to alive?&rdquo; asked Szostak.</p> <a href=http://www.scientificamerican.com/blog/post.cfm?id=how-did-life-begin-on-earth-2010-06-29>[More]</a><br clear="both" style="clear: both;"/>

          string(5371) "<p>LINDAU, Germany--What steps led to the  origin  of life on Earth? Scientists may be zeroing in on that most profound of questions. &ldquo;We&rsquo;ve gone a long way to showing&rdquo; the processes that &ldquo;set the stage&rdquo; for cellular life on Earth, Jack Szostak said Tuesday here in his talk at the 60th annual  Nobel Laureate  Lectures at Lindau .</p><p>Recent findings--such as that life seems to be everywhere on Earth--have encouraged scientific inquiries into the nature of life&rsquo;s beginnings, said Szostak. Along with Elizabeth H. Blackburn and Carol W. Greider, Szostak won the  2009 Nobel Prize in Physiology or Medicine  for work in understanding telomeres [see Blackburn and Greider's  Scientific American  article  &ldquo;  Telomeres, Telomerase and Cancer  &rdquo;]. His talk focused on his recent research on life&rsquo;s start [see his  Scientific American   2009 article, &ldquo; The Origin of Life on Earth &rdquo;]. He cited discoveries of microbes eking out existence in steaming hot springs in Yellowstone, in an acidic environment in Rio Tinto, Spain, and other hostile locations. &ldquo;Even in rocks, there&rsquo;s life,&rdquo; he added, showing the audience an image of a green streak tenaciously spreading through rock. &ldquo;Once life gets started, it can adapt and colonize many, many different environments.&rdquo; In addition, astronomers have found hundreds of  planets in other solar systems , and the space-based  Kepler telescope  recently identified more than 700 more candidate exoplanets. Many of those could have Earth-like conditions, raising the possibility that they also could harbor some form of life. How common might life be? &ldquo;The question is: Is it easy or hard to make the transition in the chemistry of planets from not alive to alive?&rdquo; asked Szostak.</p> <a href=http://www.scientificamerican.com/blog/post.cfm?id=how-did-life-begin-on-earth-2010-06-29>[More]</a><br clear="both" style="clear: both;"/>

Here we provide the surprising origins of some strange and familiar things.</p><p> All In The Family   <a href=http://www.scientificamerican.com/article.cfm?id=origins-aug-2010>[More]</a><br clear="both" style="clear: both;"/>
