These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen and methane).]]></description><comments>1</comments><score>201</score><crdate>12/4/2007 8:55:58 AM</crdate><rssdate></rssdate><atomdate>2007-12-04T08:55:58+01:00</atomdate></link><link><id>39852</id><url>http://www.plime.com/science/l/39852/1/</url><title><![CDATA[Origin of &quot;Breathable&quot; Atmosphere on Earth Found]]></title><description><![CDATA[Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today.
