Some scientists called it the highlight of their career. On March 30, physicists at the Large Hadron Collider smashed together two proton beams. Each was moving with an energy equivalent to 3.5 trillion electron volts, for a combined 7 trillion--a new world-record energy level. The victory was a long time coming for CERN, Europe's nuclear-research group, which for 15 years has pumped $10 billion into the setback-plagued project. The experiments are expected to reveal much about the nature of the universe, including other dimensions, dark matter and the Higgs boson, the particle that could explain...
...find the Higgs boson is to create an environment that mimics the moment post-Big Bang. The powerful LHC runs at up to 7 trillion electron volts (TeV) and sends particles through temperatures colder than deep space at velocities approaching the speed of light. (The second most powerful particle accelerator, at Fermilab in Illinois, runs at 1 TeV.) The added juice allows scientists to get closer to the high energy that existed after the Big Bang. And high energies are needed, because the Higgs is thought to be quite heavy. (In Einstein's famous equation E=MC2, C represents...
...radio signals that might indicate intelligent life in the universe, and ClimatePrediction.net, which tests the accuracy of global climate models, have long tapped volunteers' home computers to help process data. The difference between these projects and Galaxy Zoo - and its inspiration, Stardust@home, which asks volunteers to search electron-microscope images for interstellar dust particles collected in space - is that the latter two interface with not the volunteer's PC but with his or her mind...
