Planck: Gravitational waves remain elusive
Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.
Particle, meet wave: Optical qubit technique squeezes photons to bridge discrete and continuous quantum regimes
World's best thermometer made from light
(Phys.org) —University of Adelaide physics researchers have produced the world's most sensitive thermometer – three times more precise than the best thermometers in existence.
Massive neutrinos may not bring about cosmological concordance after all
Physicists suggest theory versus observational differences in the sun could be due to dark matter
Physicists show 'molecules' made of light may be possible
It's not lightsaber time, not yet. But a team including theoretical physicists from the National Institute of Standards and Technology (NIST) has taken another step toward building objects out of photons, and the findings ...
Engineering discovery brings invisibility closer to reality
Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, ...
Researchers make magnetic graphene
Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, ...
