An international team of astrophysicists has discovered a galaxy 65 million light years away with so little dark matter that it may contain none at all.
When the CERN safety team and I heard the loud rumbling 25 meters underground, we weren't concerned. With no warning, it would have been frightening, but the rush of water through pipes overhead presaged a thrilling event.
The United States has contributed the energy and expertise of hundreds of scientists and engineers, and more than half a billion dollars to the construction of the LHC particle collider and two of its experiments at the European laboratory CERN.
Walk into the main CERN cafeteria at various times of the day and you'll find different scenes: scientists discussing results over coffee; a parent coaxing his children to finish lunch before swooping them back to the nursery school on site; groups of grad students soaking up the sun on the
Building the parts for the Large Hadron Collider has presented challenges but taught many lessons for both particle physics laboratories and their industry partners.
To deal with the computing demands of the LHC experiments, scientists have created the world's largest, most international distributed-computing system.
