The startup corporation Terrapower funded in part by Bill Gates has an innovative plan for a reactor that can burn depleted uranium . Depleted uranium is currently a dangerous waste product produced by conventional lightwater reactors . Enough uranium-238 exists in depleted uranium , uranium deposits , and seawater to meet the earth's energy requirements for centuries . In an interview with Sander Olson For Nextbigfuture Terrapower nuclear Engineer Robert Petroski describes how reactors using depleted uranium could potentially play a major role in ameliorating the

Geneva, 26 August 2011. Results to be presented by CERN 's LHCb experiment at the biennial Lepton-Photon conference in Mumbai, India on Saturday 27 August are becoming the most precise yet on particles called B mesons, which provide a way to investigate matter-antimatter asymmetry. The LHCb experiment studies this phenomenon by observing the way B mesons decay into other particles. The new results reinforce earlier measurements from LHCb presented at last month's European Physical Society conference in Grenoble, France showing that the B meson decays so far measured by the collaboration are in full agreement with predictions from the Standard Model of particle physics, the theory physicists use to describe the behaviour of fundamental particles.

(PhysOrg.com) -- By demonstrating that an artificial atom embedded in a transmission line can route a single photon from an input port to one of two output ports, physicists have built the first router working at the single-photon level. The single-photon router could one day serve as a quantum node in a quantum information network, in which it could provide basic processing and routing of data.

Geneva, 22 August 2011. Results from the ATLAS and CMS collaborations, presented at the biannual Lepton-Photon conference in Mumbai, India today, show that the elusive Higgs particle, if it exists, is running out of places to hide. Proving or disproving the existence the Higgs boson, which was postulated in the 1960s as part of a mechanism that would confer mass on fundamental particles, is among the main goals of the LHC scientific programme. ATLAS and CMS have excluded the existence of a Higgs over most of the mass region 145 to 466 GeV with 95 percent certainty.

(PhysOrg.com) -- It has all the appearances of a breakthrough in battery technology, except that it’s not a battery. Researchers at Nanotek Instruments, Inc., and its subsidiary Angstron Materials, Inc., in Dayton, Ohio, have developed a new paradigm for designing energy storage devices that is based on rapidly shuttling large numbers of lithium ions between electrodes with massive graphene surfaces. The energy storage device could prove extremely useful for electric vehicles, where it could reduce the recharge time from hours to less than a minute. Other applications could include renewable energy storage (for example, storing solar and wind energy) and smart grids.

BEIJING BERKELEY, CA and UPTON, NY - The Daya Bay Reactor Neutrino Experiment has begun its quest to answer some of the most puzzling questions about the elusive elementary particles known as neutrinos. The experiment's first completed set of twin detectors is now recording interactions of antineutrinos (antipartners of neutrinos) as they travel away from the powerful reactors of the China Guangdong Nuclear Power Group in southern China.
