Scientists are developing a way to easily manipulate and store light such that photons can be used on demand, a technique that may one day become integral in quantum-information transfer, fiber-optics and theories that remain untested due to light-based restrictions.

Physics without determinism: Alternative interpretations of classical physics

A new on-chip “wire” for sound promises phononic circuits for classical signal processing and cryogenic quantum systems.

X-rays can melt silicon in 100 fs - the time it takes light to travel the width of a human hair

Physicists create graphene circuit, prove that Brownian motion can do work

A new magnetic metamaterial allows "unprecedented focusing of magnetic fields in empty space and enables the remote cancellation of magnetic sources, opening an avenue for manipulating magnetic fields in inaccessible regions."

Gravitational Test beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole

Aalto University researchers have developed a black silicon photodetector that has reached above 130% efficiency in UV range without external amplification, breaking the theoretical one-photon–one-electron barrier known as the Shockley-Queisser limit

Falling rain produces electrostatic charges when it hits a surface

While astronomers look for a ninth planet to explain orbits in the outer solar system, a duo explores the possibility that the mystery object is a primordial black hole.

Black-silicon ultraviolet photodiodes achieve external quantum efficiency above 130%

Physicists at the Goethe University in Frankfurt first detect the phenomenon experimentally, which was predicted by Arnold Sommerfeld in 1930: When a particle of light strikes an atom…

Scientists demonstrate that anesthetized brains become both less structured and more reversible.

Physical Implications of a Fundamental Period of Time - A strong upper bound T_C < 10^− 33 s of the fundamental period of time, several orders of magnitude below any direct time measurement, is obtained from bounds on dynamical variations of the period of a system evolving in time.

A proposed interaction between neutrinos might explain a discrepancy in measurements of the Universe’s expansion rate.
