Recycling gives new purpose to spent nuclear fuel

Imagine filling up your gas tank with 10 gallons of gas, driving just far enough to burn a half gallon and discarding the rest. Then, repeat. That is essentially the practice that the U.S. nuclear industry is following.

Ultra-high-energy gamma rays originate from pulsar nebulae

The discovery that the nebulae surrounding the most powerful pulsars are pumping out ultra-high-energy gamma rays could rewrite the book about the rays' galactic origins. Pulsars are rapidly rotating, highly magnetized collapsed ...

Not so fast, supernova: Highest-energy cosmic rays detected in star clusters

For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova—when they grow too massive to support the fusion occurring at their cores and ...
