Surprisingly, rumors still persist in some corners of the Internet that the Large Hadron Collider (LHC) is going to destroy the Earth even though nearly three years have passed since it was first turned on.

Feed SubscriptionMagnetic memories manipulated by voltage, not heat
In their search for smaller, faster information-storage devices, physicists have been exploring ways to encode magnetic data using electric fields. One advantage of this voltage-induced magnet control is that less power is needed to encode information than in a traditional system.

Is it time for a communications paradigm shift? Scientists calculate that encoding and sending information via electron spin, instead of voltage changes, may mean tiny chips could transmit more information and consume less power.

(PhysOrg.com) -- Results presented by CERN1'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.

(PhysOrg.com) -- A new tool developed by nuclear engineers at Purdue University will be hitched to an experimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and interact with the inner surface of the reactor.

(PhysOrg.com) -- A new x-ray microscopy technique that allows scientists to make images 60 times faster than before has been developed by an Australian research team including Garth Williams, who is now an instrument scientist at SLACs Linac Coherent Light Source. The method, called polychromatic coherent diffractive imaging, or polyCDI, will also enable sharper and more accurate images of floppy biological molecules and fast-moving materials structures.

Physicists with the Institute of Ultrafast Spectroscopy and Lasers (IUSL) at The City College of New York have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased bandwidth would ease the burden on fiber-optic telecommunications networks taxed by an ever-growing demand for audio, video and digital media

(PhysOrg.com) -- The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses. This idea was something that went against most commonly accepted theories of how the subatomic world works.

(PhysOrg.com) -- A team of physicists comprised of members from IBM Research in Switzerland and the University of Liverpool in the U.K. have figured out a way to improve on results obtained using a Scanning Tunneling Microscope (STM) that allows for the orbitals of single molecules to be mapped. They have published a paper on Physical Review Letters describing their procedure.

(PhysOrg.com) -- Jasper Kirkby, a physicist at CERN and colleagues have built an experimental climate chamber to measure the impact of cosmic rays on aerosol creation to mimic the creation of clouds in Earth's atmosphere. So far, as the team describes in their paper published in Nature, there appears to be some evidence of aerosol creation, but not enough to account for cloud formation, and thus theres no evidence yet to show that cosmic rays have an impact on global temperatures.

The elusive Higgs Boson, known as the "God particle", is -- if it exists -- running out of places to hide, the head of the mammoth experiment designed to find it said on Thursday.

(PhysOrg.com) -- When generating entanglement between two objects, physicists typically try to minimize the objects interactions with the environment, since this interaction causes decoherence. But contrary to this thinking, scientists in a new study have experimentally demonstrated that dissipation caused by interaction with the environment can continuously generate entanglement between two macroscopic objects (two ensembles of cesium atoms containing about 1 trillion atoms all together).
