Solar wind energy source discovered
Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later ...
Researchers build acoustic tractor beam
A new way to make laser-like beams using 250x less power (Correction)
With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a ...
Physicists develop revolutionary low-power polariton laser
(Phys.org) —Lasers are an unseen backbone of modern society. They're integral to technologies ranging from high-speed Internet services to Blu-ray players.
Physics team entangles photons that never coexisted in time
Researchers propose using distant quasars to test Bell's theorem
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's inequality—a 50-year-old theorem that, if vio ...
Understanding a new kind of magnetism
Using low-frequency laser pulses, a team of researchers has carried out the first measurements that reveal the detailed characteristics of a unique kind of magnetism found in a mineral called herbertsmithite.
Should the Higgs boson have caused our Universe to collapse?
(Phys.org) —British cosmologists are puzzled: they predict that the Universe should not have lasted for more than a second. This startling conclusion is the result of combining the latest observations of ...
Researchers find possible evidence of toroidal magnetic field surrounding magnetar
Researchers suggest dark matter disk in Milky Way plane could signal rash of comet strikes on Earth
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
Researchers demonstrate proof of creation of a mirror by optical matter
Superconductivity in orbit: Scientists find new path to loss-free electricity
(Phys.org) —Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor ...
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
