For the first time since 2013, protons are swirling around the Large Hadron Collider's 16.8-mile loop, as CERN brings its baby back online after a two-year, $150 million rebuild. With the "God particle" now under its belt, CERN is hoping for bigger and better things out of LHC 2.0, reports the BBC—including about twice the operating energy achieved during its first time around and more violent collisions."It's fantastic to see it going so well after two years and such a major overhaul of the LHC," says CERN director Rolf Heuer. The collider is set to hit its stride in June, and scientists are hoping this time for a peek at dark matter, notes the AP. (More Large Hadron Collider stories.)
