In a unique experiment on a galactic scale, millions of bacterial
spores have been purposely exposed to space, to see how solar radiation
affects them and the results supported the idea that not only could
life have arrived on Earth on meteorites, but that considerable
material has flowed between planets.</P></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://www.dailygalaxy.com/my_weblog/2008/05/galactic-microb.html"><P>Closer to home, scientists have analyzed aerial dust samples collected by Charles Darwin and confirmed that microbes can travel across continents without the need for planes or trains - rather bacteria and fungi hitch-hike by attaching to dust particles. Their results clearly show that diverse microbes, including
ascomycetes, and eubacteria can live for centuries and survive
intercontinental travel.</P></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://www.dailygalaxy.com/my_weblog/2008/05/galactic-microb.html"><DIV>In a paper published in Environmental Microbiology, Dr. Anna Gorbushina
