OSIM's job is to generate a beam of light just like the one that the real telescope optics will feed into the actual flight instruments. Because the real flight instruments will be used to test the real flight telescope, their alignment and performance first have to be verified by using the OSIM. Engineers are thoroughly checking out OSIM now in preparation for using it to test the flight science instruments later. http://phys.org/news265018155.html Space & Earth Fri, 24 Aug 2012 09:12:46 EST news265018155 Whether a material conducts electricity without losses is not least a question of the right temperature.

But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. The small quantities of tissue extracted during routine diagnostic biopsies have not been useful to researchers, due to their small size and the variety of ways they have been processed. http://phys.org/news198425936.html Medicine & Health Thu, 15 Jul 2010 15:19:34 EST news198425936 "I don't ever want to die...
