Planned Nuclear Reactors Will Destroy Atomic Waste 344

Posted by Soulskill from the but-where-will-we-get-our-superheroes dept.
separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

Gamma Ray Mystery Reestablished By Fermi Telescope 95

Posted by Soulskill from the back-to-the-drawing-board dept.
eldavojohn writes "New observations from NASA's Fermi Gamma-ray Space Telescope reveal that our assumptions about the 'fog' of gamma rays in our universe are not entirely explained by black hole-powered jets emanating from active galaxies — as we previously hypothesized. For now, the researchers are representing the source of unaccounted gamma rays with a dragon (as in 'here be') symbol. A researcher explained that they are certain about this, given Fermi's observations: 'Active galaxies can explain less than 30 percent of the extragalactic gamma-ray background Fermi sees. That leaves a lot of room for scientific discovery as we puzzle out what else may be responsible.' And so we reopen the chapter on background gamma-rays in the science textbooks and hope this eventually sheds even more light on other mysteries of space — like star formation and dark matter."

Interesting. I'm 35 and grew up just north of Salt Lake City. At the time, I didn't know a single, solitary person--not one--who believed in evolution. I was taught repeatedly that the stories in the Bible (Garden of Eden, Noah's Flood, David and Goliath, pillars of salt, the whole bit) were historical facts, and that if I couldn't accept that, I couldn't be a Mormon. I eventually left Mormonism for a host reasons, but the whole attitude towards reality sure didn't help. I'm glad others have had better experiences.
