The mysterious 'action at a distance' between liquid containers
(Institute of Physical Chemistry of the Polish Academy of Sciences) For several years, it has been known that superfluid helium housed in reservoirs located next to each other acts collectively, even when the channels connecting the reservoirs are too narrow and too long to allow for substantial flow. A new theoretical model reveals that the phenomenon of mysterious communication 'at a distance' between fluid reservoirs is much more common than previously thought.

Particles, waves and ants
(Vienna University of Technology) Particles or waves traveling through disordered media are scattered at small impurities. Surprisingly, the density of these impurities does not affect the overall dwell time the particle -- or wave -- spends inside the medium. This remarkable finding applies not only to particles and waves, but also to crawling ants or drunken sailors hitting streetlamps.

Protons fuel graphene prospects
(University of Manchester) Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it, University of Manchester researchers have found.

Van der Waals force re-measured
(Forschungszentrum Juelich) Van der Waals forces act like a sort of quantum glue on all types of matter. Scientists from Forschungszentrum Jlich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. They demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast. Their findings could help to improve simulation methods for chemistry, physics, biology, and materials science.

Stanford engineers invent high-tech mirror to beam heat away from buildings into space
(Stanford School of Engineering) Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends heat from inside the structure directly into space as infrared radiation.

'Giant' charge density disturbances discovered in nanomaterials
(Forschungszentrum Juelich) Scientists in Jlich have, with the help of computer simulations, discovered a combination of materials that strengthens the so-called Friedel oscillations and bundles them, as if with a lens, in different directions. With a range of 50 nanometers, these 'giant anisotropic charge density oscillations' are many times greater than normal and open up new possibilities in the field of nanoelectronics to exchange or filter magnetic information.

NASA's Webb Telescope mirror tripod in action
(NASA/Goddard Space Flight Center) Setting up NASA's James Webb Space Telescope's secondary mirror in space will require special arms that resemble a tripod. NASA recently completed a test of the tripod to ensure it would function properly in space.

Lawrence Livermore researchers develop efficient method to produce nanoporous metals
(DOE/Lawrence Livermore National Laboratory) Nanoporous metals -- foam-like materials that have some degree of air vacuum in their structure -- have a wide range of applications because of their superior qualities.

Physicists bind single-atom sheets with the same force geckos use to climb walls
(University of Kansas) The approach is to design synergistic materials by combining two single-atom thick sheets, for example, that act as a photovoltaic cell as well as a light-emitting diode, converting energy between electricity and radiation.

Two Rutgers professors named fellows of top national science association
(Rutgers University) Two Rutgers professors are among 401 members of the American Association for the Advancement of Science who have been elevated to the rank of fellow. The pre-eminent national organization selects its fellows based on their scientifically or socially distinguished efforts to advance science or its applications.
