A new era for nuclear. The biggest downside to nuclear power has always been about what's left behind. But now, scientists at the Department of Energy's Jefferson Lab say they may have a way to slash the radioactivity of spent fuel by 99.7 percent. Even better: they can generate usable heat in the process. To do that, they use a particle-accelerator technique called spallation. They fire high-energy protons to knock pesky isotopes into more manageable forms, potentially cutting storage timelines from 100,000 years to only a few centuries.
Virginia-based Jefferson Lab is leading a project to transform nuclear waste into usable electricity while also drastically reducing its radioactive life.
The Blood Falls is the result of a complicated interaction in which overlying ice, underlying rock, and an ancient lake bed form a pretty unsettling natural display.
While the human remains in the coffin were not those of an elite member of society (as they had once been thought to be), radiocarbon dating revealed that they were a hundred years older than assumed.
