Electron’s negativity cut in half by supercomputer

While physicists at the Large Hadron Collider smash together thousands of protons and other particles to see what matter is made of, they're never going to hurl electrons at each other. No matter how high the energy, the little negative particles won't break apart.

The world’s smallest magnetic data storage unit

Scientists from IBM and the German Center for Free-Electron Laser Science (CFEL) have built the world's smallest magnetic data storage unit. It uses just twelve atoms per bit, the basic unit of information, and squeezes a whole byte (8 bit) into as few as 96 atoms. A modern hard drive, for comparison, still needs more than half a billion atoms per byte

Optical nanoantennas enable efficient multipurpose particle manipulation

University of Illinois researchers have shown that by tuning the properties of laser light illuminating arrays of metal nanoantennas, these nano-scale structures allow for dexterous optical tweezing as well as size-sorting of particles.

Researchers conduct experimental implementation of quantum algorithm

(PhysOrg.com) -- Researchers at D-Wave Systems have carried out a calculation involving 84 qubits on an experimental quantum computer, giving some credence to the plausibility of true quantum computers being created that could vastly surpass the abilities of all those that currently rely on existing technology.

Physicists develop nano-level sound detector

(PhysOrg.com) -- For a couple of decades now, physicists have known that if a very small laser beam is pointed at a microscopic particle, it could be held in place due to the very small electrical field that is generated. Because of that, the technique has been used to hold objects in place for close examination, sort of like using a pair of tweezers to hold a grain of sand for study under a magnifying glass. One truly nice feature of the technique is that it’s very gentle, thus no harm comes to the particle being examined.

Physics team finds new constraints on how lumpy space-time can be

(PhysOrg.com) -- Robert Nemiroff and his colleagues at Michigan Technological University will be discussing new constraints on the so-called lumpiness of space-time at this year’s meeting of the American Astronomical Society.

Light control technique could lead to tunable lighting and displays

(PhysOrg.com) -- Over the past several years, organic light-emitting diodes (OLEDs) have become a popular light source due to their advantages including bright displays, wide viewing angles, and the ability to be printed on flexible substrates. A lesser known alternative to OLEDs, which has these advantages plus some additional ones such as low turn-on voltage, is electrochemical light-emitting cells (LECs).
