Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years
Correlations of quantum particles help in distinguishing physical processes
Communication security and metrology could be enhanced through a study of the role of quantum correlations in the distinguishability of physical processes, by researchers at the Universities of Strathclyde ...
Physicists reach new milestone measuring half-life of iron-60
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 ...
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 ...
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 ...
Exotic, gigantic molecules fit inside each other like Russian nesting dolls
University of Chicago scientists have experimentally observed for the first time a phenomenon in ultracold, three-atom molecules predicted by Russian theoretical physicist Vitaly Efimov in 1970.
Researchers conduct first direct measurement of gravity's curvature
Halting photons could lead to miniature particle accelerators, improved data transmission
Researchers at MIT who succeeded last year in creating a material that could trap light and stop it in its tracks have now developed a more fundamental understanding of the process. The new work—which could ...
Researchers use real data rather than theory to measure the cosmos
For the first time researchers have measured large distances in the Universe using data, rather than calculations related to general relativity.
Study outlines basic rules for construction with a type of origami
Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind the paper-folding art can also be applied to making a microfluidic device for a blood test, or for ...
Physicists explain puzzling particle collisions
An anomaly spotted at the Large Hadron Collider has prompted scientists to reconsider a mathematical description of the underlying physics. By considering two forces that are distinct in everyday life but ...
Researchers learn more about the possible role of gamma ray bursts on life extinction in the universe
World record for compact 'tabletop' particle accelerator
Using one of the most powerful lasers in the world, researchers have accelerated subatomic particles to the highest energies ever recorded from a compact accelerator.
