Study Confirms Time Dilation Predicted for High Velocities in the Theory of Relativity

To explore any possible limits of the two theories, they have been experimentally verified many times already and both have passed all the tests so far. Hence, scientists look for deviations in experiments with increasing precision or under extreme conditions.

Bosonic Super-WIMPs May Not Constitute All Dark Matter

The XMASS collaboration, led by Yoichiro Suzuki at the Kavli IPMU, has reported its latest results on the search for warm dark matter. Their results rule out the possibility that super-weakly interacting massive bosonic particles (bosonic super-WIMPs) constitute all dark matter in the universe. This result was published in the September 19th issue of the Physical Review Letters as an Editors' Suggestion.

Researchers Use Quantum World Properties to Detect Magnetism with Atom-by-Atom Precision

Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Such measurement technique would give engineers and physicists an ultimate handle over magnetic properties of nano-structures for future applications.

Daya Bay Collaboration Releases First Results on Search for Sterile Neutrinos

The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a possible new type of neutrino beyond the three known neutrino "flavors," or types.

Nuclear Scientists Refine Measurement of Remarkable Property of Quark-Gluon Plasma

By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, “perfect fluid” that give clues to the state of the young universe just microseconds after the big bang.

Innovative Technique Directly Generates Cross-Polarized Correlated Photons on a Chip

Commercial devices capable of encrypting information in unbreakable codes exist today, thanks to recent quantum optics advances, especially the generation of photon pairs—tiny entangled particles of light. Now, an international team of researchers led by professor Roberto Morandotti of INRS-EMT in Canada, is introducing a new method to achieve a different type of photon pair source that fits into the tiny space of a computer chip.
