Observations of early universe hint at a giant excess of anti-neutrinos
'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 ...
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 ...

Power grid upgrades may cause blackouts, warns Braess's paradox
Lenses can bend light and sound in almost any direction
'Building block' of quanutm networks created
(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.
Researchers develop fast, sensitive nanophotonic motion sensor developed for silicon microdevices
(Phys.org)—Using a microscopic optical sensor that can be batch-fabricated on a silicon chip at low cost, researchers from the NIST Center for Nanoscale Science and Technology have measured the mechanical ...
Scientists take steps toward creating artificial graphene
Thousands of invisibility cloaks trap a rainbow
Many people anticipating the creation of an invisibility cloak might be surprised to learn that a group of American researchers has created 25 000 individual cloaks.
Solar and wind energy may stabilise the power grid
(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical ...
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.
'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.
Towards 'unbreakable' message exchange
Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks.
