Hey Bert, I suppose the first part is for you. I just read an abstract of an article that is supposed to be published in a physical chemistry journal about Pu 238 and its use as an energy source, specifically for long range space satelites and such. I guess some crazy ass group over in germany or norway have built a long range fuel supply system using Pu 238 that supposedly can power a small satelite for upwards of 50 years (I don't know how they calculated that as I am no good at that "math" religion).
Secondly, a group in Japan just published an article on the successful use of fetal stem cells to grow healthy adult cells. If I can find an online version of the article, I will post it.
Go Science!
Bam!
