Life is contradictable. Some microorganisms start multiplying instead in UV. I UV radiated a silver plate dipped in ethylen glycos, and after some hours, you could see greyish veils on the silver surface: kind of fungi, size about one to several micrometers. They were there somewhere already before the test, of course. A university here has a number of doctorands who study microorganic growth caused by enhanced condition which comes from IR-radiated ethylene glycos, which break down to kind of organic compounds on which the few microorganisms feast,and become millions in short time. Silver is often used as anti-bacteria stuff, but life can tunnel through even that in some cases. Unbelievable. If someone is curious, I can send a photo on my unwanted babies to Steve.
