Synopsis: Hydrodynamic Cloaks
Two separate groups have designed structures that can hide objects from fluid flows and surface waves so that no wake is visible. Read More »
Synopsis: Seeking Stardust in the Snow
Iron-60 found in fresh Antarctic snow was forged in nearby supernovae and could help deduce the structure and origin of interstellar dust clouds. Read More »
Focus: Entangling Photon Sources on a Tiny Bridge
Researchers entangled a pair of atomic-scale light emitters in a micrometer-scale device, which could potentially be useful for quantum communication and cryptography. Read More »
Synopsis: Entangling the Radial Parts of Photons
Correlations between the radial position and radial momentum of entangled photons demonstrate the suitability of these properties for quantum information applications. Read More »

Synopsis: Laser Stars for Astrophysical Calibrations
Laser-generated “stars”—used at telescopes to correct for atmospheric turbulence—could help researchers calibrate the wavelengths of certain astrophysical observations. Read More »
Viewpoint: A Laser-Sharp View of Electron Correlations
A high-resolution photoemission experiment provides an unprecedented test of a theory describing the effects of strong electron correlations in solids. Read More »
Focus: Light Seems to Pull Electrons Backward
Light hitting a metal surface at an angle sends the electrons moving in the direction opposite to the light, a result that puzzles theorists. Read More »
