The Department of Energy just delivered a shipment plutonium that NASA will turn into radioisotope thermoelectric generators (RTGs) for future missions.

Now that the Large Hadron Collider has measured the mass of the Higgs boson, physicists are trying to understand how these particles interact with the rest of the Universe. One theory is that decaying Higgs bosons could produce "dark photons," which would only live for about a tenth of a billionth of a second. That doesn't sound like much, but it's long enough to detect "displaced muons," a by-product of the decay that would indicate the presence of dark photons.
