The odds are improving that life exists beyond Earth. A European-U.S. team reports that a meteorite that formed billions of years ago and eventually crashed on our planet harbors two important components of RNA and DNA, the fundamental molecules of life. The findings could help explain how life got started on Earth, and they suggest that the ingredients for life have been liberally sprinkled throughout the solar system, if not the galaxy.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://sciencenow.sciencemag.org/cgi/content/full/2008/616/1?etoc">
So far, the clues for extraterrestrial life are tantalizing but inconclusive.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://sciencenow.sciencemag.org/cgi/content/full/2008/616/1?etoc">suggest that life's most important molecule could form off our planet. The researchers dissolved and purified fragments from the Murchison meteorite, which was found in Australia in 1969. Chemical analysis showed that the meteorite contains xanthine and uracil, substances called nucleobases that are necessary for RNA and DNA to form their base pairs as part of their replication process.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/B493B558-55E6-47A5-990C-6257F192F791/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
