<P id=ynw-article-part2>Researchers in the US unleashed swarms of the tiny 
artificial particles on human breast and skin tumours in mice.</p> <P>Each spherical "nanobee", measuring just three millionths of an inch across, 
was armed with a cancer-killing toxin found in bee venom.</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://uk.news.yahoo.com/21/20090811/thl-nanobees-sting-tumours-to-death-d831572.html">
