Researchers at the University of Southampton and the Korea Institute for Advanced Study have recently showed that supersymmetry is anomalous in N=1 superconformal quantum field theories (SCFTs) with an anomalous R symmetry. ...
(Phys.org)—Although in theory it may seem possible to divide time up into infinitely tiny intervals, the smallest physically meaningful interval of time is widely considered to be the Planck time, which is approximately ...
(Phys.org) —Quantum electrodynamics (QED) – the relativistic quantum field theory of electrodynamics – describes how light and matter interact – achieves full agreement between quantum mechanics and special relativity. ...
(Phys.org)—A widely-used tool for studying cellular structure – indeed, a technique in use throughout biology – phase contrast microscopy converts optical phase shifts to changes in brightness. At the same time, several ...
(PhysOrg.com) -- While black holes in four-dimensional space-time are stable and can persist for a long time, their higher-dimensional analogues are usually unstable. One such theoretical analogue is a five-dimensional black ...
Physicists at UC Santa Barbara, the University of Maryland, and the University of Washington have found an answer to the longstanding physics question: How do interparticle interactions affect dynamical localization?

(Phys.org)—Human speech is not typically thought to adapt to the environment, and a standard assumption in linguistics is that sound systems are in fact immune to ecological effects. Recently, however, scientists at University ...
(Phys.org) —A team of climate experts from Britain's national weather service (The Met Office) has given a series of presentations at the Science Media Centre in London with the aim of trying to explain why global warming ...
A billon-frames-per-second film has captured the vibrations of gold nanocrystals in stunning detail for the first time.
