(PhysOrg.com) -- CERN today announced that the Large Hadron Collider will run with a beam energy of 4 TeV this year, 0.5 TeV higher than in 2010 and 2011. This decision was taken by CERN management following the annual performance workshop held in Chamonix last week and a report delivered today by the external CERN Machine Advisory Committee (CMAC).

The National Nuclear Security Administration (NNSA) today announced that researchers from Sandia and Los Alamos national laboratories have completed their second experiment in the past six months at Sandia’s Z machine to explore the properties of plutonium materials under extreme pressures and temperatures.

Fujitsu today announced the achievement of a 40 gigabits per second (40-Gbps) optical-fiber transmission employing an uncooled directly-modulated laser. This was realized through the combination of a structure specifically adapted to high-speed operation, and a newly-developed structure capable of lowering operating current and enabling high-temperature operation. Featuring power consumption at less than half that of commercialized 40-Gbps optical transmitters, Fujitsu's new directly-modulated laser obviates the need for a thermoelectric controller
