nuclear energy gets leg up with new technologies-this is but one example of why I'm optimistic on America-we continue to be the innovators-I'm no fan of nuclear, but if we're gonna go that way, this is a good development!

supercomputers to simulate <A

repair themselves</A> after radiation-induced damages. This is an important 
discovery because ‘materials that can resist radiation damage are needed to 
expand the use of nuclear energy.’ These ceramics, which are able to handle 
high-radiation doses, could improve the durability of nuclear power plants. They 
also might help to solve the problem of nuclear waste storage.</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://blogs.zdnet.com/emergingtech/?p=897">“‘If you want a material to withstand radiation over millennia, you can’t expect 
it to just sit there and take it. There must be a mechanism for self-healing,’
