Gravity's lingua franca: Unifying general relativity and quantum theory through spectra; geometry
(Phys.org) —Mathematics is, in essence, an artificial language for precisely articulating theories about the physical world. Unlike natural language, however, translating different classes of mathematics ...
'Spooky action at a distance' aboard the ISS
(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively ...
Don't call it vaporware: Scientists use cloud of atoms as optical memory device (w/ video)

Optical random access memory: Parts of images can be selectively retrieved from an atomic gas
(Phys.org) —The sequence of images that constitute Hollywood movies can be stored handily on solid-state media such as magnetic tape or compact diskettes. At the Joint Quantum Institute images can be stored ...
'Metascreen' forms ultra-thin invisibility cloak
(Phys.org) —Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions – an obvious flaw for those interested in Harry Potter-style applications.
Observations of early universe hint at a giant excess of anti-neutrinos
(Phys.org) —Scientists have a great deal of evidence to support the fact that the universe contains much more baryonic matter than baryonic anti-matter, a phenomenon known as baryon asymmetry. Baryons, ...
Feynman's double-slit experiment brought to life
(Phys.org) —The precise methodology of Richard Feynman's famous double-slit thought-experiment – a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave – has ...

(Phys.org)—A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US.
Physics on a plane: Crystals grown under zero gravity
(Phys.org)—A group of physicists from Japan have taken to the skies to grow crystals under zero gravity.
Formula unlocks secrets of cauliflower's geometry
The laws that govern how intricate surface patterns, such as those found in the cauliflower, develop over time have been described, for the first time, by a group of European researchers.
Power grid upgrades may cause blackouts, warns Braess's paradox
(Phys.org)—In order to meet increasing energy demands, power companies have the option of adding new power lines to the existing grid. But in a new study, researchers have found that, contrary to common ...
Study confirms magnetic properties of silicon nano-ribbons
