Well, the opening paragraph does lead one to believe that:<br /><br />"NASA clean rooms[,...], have joined [...] as unlikely places where scientists have discovered ultra-hardy organisms collectively known as ‘extremophiles’. Some species of bacteria uncovered in a recent NASA study have never been detected anywhere else."<br /><br />That sure sounds like "we discovered bacteria that haven't been seen anywhere but our clean rooms". That's how I'd have summarized it. That said - I agree it's poorly and ambiguously written...<br /><br />The guy in the photo doing the sampling has exposed body hair. The clean-rooms I work in are all bunny-suited. I don't want to imagine how much he's tracking in on those eyebrows. And the guys in the background look similarly attired. No filtration or independant air supply either. I'd expect the place to be rife with bacterium, spores, virii, etc. Surveying is a good idea, but with everything not being controlled by the absense of a bunnysuit in that picture, I think I'd be concerned more with a false-negative on a sample than a false-positive.<br /><br />I do find it interesting that a hard drive platter is infinitely more sterile than a space-craft looking for E.T. <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <p>.</p><p><font size="3">bipartisan</font> (<span style="color:blue" class="pointer"><span class="pron"><font face="Lucida Sans Unicode" size="2">bī-pär'tĭ-zən, -sən</font></span></span>) [Adj.] Maintaining the ability to blame republications when your stimulus plan proves to be a devastating failure.</p><p><strong><font color="#ff0000"><font color="#ff0000">IMPE</font><font color="#c0c0c0">ACH</font> <font color="#0000ff"><font color="#c0c0c0">O</font>BAMA</font>!</font></strong></p> </div>
