Light bends by itself
ScienceNOW
Share
   
Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. The effect is actually an optical illusion, although the researchers say it could have practical uses such as moving objects with light from afar. Read the associated APS Physics Viewpoint.

Electron splits into quasiparticles
Scientific American
Share
Although isolated electrons are fundamental particles that cannot be split into smaller components, in some systems they can act as though they consist of multiple pieces. In a feat of technical mastery, condensed-matter physicists have managed to detect a particularly elusive constituent of an electron in matter - its 'orbiton'. The achievement could help to resolve a long-standing mystery about the origin of high-temperature superconductivity, and aid in the construction of quantum computers.

'Magnetic Josephson effect' seen for the first time
Physics World
Share
A fundamental prediction of superconductivity theory has been demonstrated in the lab for the first time. An international team of physicists has observed coherent quantum phase slip, a phenomenon similar to the well-known Josephson effect in which magnetic flux takes the place of electric charge. Its discovery has fundamental implications for our understanding of macroscopic quantum systems and could also lead to intriguing applications, including a possible way to produce a qubit in a quantum computer.

Particle physics: A matter of detail
Nature News

Physicists at Fermilab are preparing the Main Injector Neutrino Oscillation Search (MINOS) experiment to provide a precise measurement of neutrino speeds. The effort is intended to definitely determine whether or not the particles can travel faster than the speed of light.

Floating offshore wind kit gets spur from US, Britain
Bloomberg
Share
Britain and the U.S. said they'd fund work on offshore wind generation technologies that work in waters as much as 500 feet deep, a measure aimed at opening vast new areas of ocean to development. U.S. Energy Secretary Steven Chu and his U.K. counterpart Edward Davey said their departments will collaborate on ways to spur development of floating platforms for offshore wind turbines that can be stationed in depths beyond 60 meters (200 feet), the limit for traditional structures fixed to the seabed.

Cosmic-ray theory gets the cold shoulder
Physics World
Share
One of the leading theories describing how the most energetic cosmic rays are produced may need a rethink in light of a new study by physicists at the IceCube Neutrino Observatory in Antarctica. The team had set out to detect the extremely energetic neutrinos that are expected to be produced alongside high-energy cosmic rays in the violent explosions that mark the deaths of massive stars - but after looking at hundreds of these explosions, no such neutrinos have been found.

With the latest piece of the puzzle about to be published in the journal Physical Review Letters, a solar system mystery that has perplexed people for more than 20 years has been solved. That mystery is the "Pioneer Anomaly," an anomalous acceleration that affected the two Pioneer spacecraft as they left the solar system. Read the abstract of the forthcoming Physical Review Letters article.

Quantum decision affects results of measurements taken earlier in time

A new analysis of certain experiments that involve quantum mechanically entangling multiple particles together suggests that you can take a measurement before the final entanglement takes place, but the measurement's results depend on whether or not you subsequently perform the entanglement.
