Physicists discover 'magnetotoroidic effect'
PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
For many years, scientists have known about the magnetoelectric effect, in which an electric field can induce and control a magnetic field, and vice versa. In this effect, the electric field has always been homogeneous. Now, scientists have found that a curled electric field can also be used to control magnetic fields, constituting a novel phenomenon that they call the "magnetotoroidic effect." Read the associated Physical Review Letters abstract. More

Neutrinos seen to fly faster than light
Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A startling neutrino experiment has called into question Einstein's theory of special relativity. Even though few believe that these results will ultimately hold up, their implications have stirred up quite a fuss. Read the associated Physical Review D abstract. More



'Antimagnet' joins list of invisibility approaches
BBC News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have designed a "cloak" that is invisible to magnetic fields both coming in and coming out. The idea of blocking magnetic fields has been proposed before, but the new design could even hide magnetic materials. More

Electrons surf between qubits
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Two independent groups of physicists have taken an important step towards the creation of a practical quantum computer by showing how to transfer single electrons over relatively long distances between quantum dots. Both schemes involve using sound waves on the surface of a material to propel electrons between the quantum dots - which are sub-micron-sized pieces of semiconductor. The teams are confident that they will soon be able to show that electrons arrive at their destination with their quantum information intact, making the system a viable "quantum data bus" for a quantum computer.

Ferrofluid pump has no moving parts
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists have developed a new way of pumping ferrofluids without the use of any mechanical components. They claim that their technique, dubbed "ferrohydrodynamic pumping," can be easily scaled up or down to be used in microfluidic devices or industrial-scale pumping devices, and anything in between.

Texas holds firm on physics closures
Nature News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Texas higher-education officials delivered a stern message to physicists that the state is likely to stick to plans to phase out 'low-performing' physics programs within the next year or two if they cannot demonstrate compelling plans to improve. More

Carbon capture progress has lost momentum, says energy agency
The Guardian    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The financial crisis and fading government support for climate action have seriously eroded global plans to capture and store carbon, the International Energy Agency (IEA) warned. More

Atomic mirror
Science News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A single atom that acts like a mirror could lead to transistors for computers that use light instead of electricity to perform computations. Read the associated APS Physics Synopsis. More
