Scientists working as part of the Metrology for Energy Harvesting Project have developed a new model to deliver the maximum power output for piezoelectric energy harvesters.

(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).

By Nina Chestney LONDON, Jan 6 (Reuters) - The global economy could withstand widespread disruption from a natural disaster or attack by militants for only a week as governments and businesses are not sufficiently prepared to deal with unexpected events, a report by a respected think-tank said. Events such as the 2010 volcanic ash cloud, which grounded flights in Europe, Japan's earthquake and tsunami and Thailand's floods last year, have showed that key sectors and businesses can be severely affected if disruption to production or transport goes on for more than a week

A new advanced imaging scheme—with a resolution ten times better than that of its counterparts to date—can resolve objects as small as atoms1. Previously, the maximum resolution of optical instruments, including cameras and microscopes, was fundamentally limited to a precision that corresponded to approximately half of the wavelength of incoming light.
