(Phys.org)—Over the past few years, scientists have demonstrated the phenomenon of "one-way light," in which a light beam propagates in one direction only. The materials used to achieve this effect can be thought of as optical ...

(Phys.org)—Most people think of music as more of an art than a science. Although sound is a wave, and can therefore be described by the laws of physics, understanding how certain patterns of sound waves create what we perceive ...

(Phys.org)—Quantum key distribution (QKD) may one day allow for nearly perfectly secure data communication on a large scale, but before this can happen, QKD networks must extend across distances that are large enough to connect ...

(Phys.org)—Researchers have fabricated a stretchable and transparent electrode that can be used for applications such as heating parts of the body and defrosting the side view mirrors on cars. It is the first stretchable ...

(Phys.org)—Under ancient Jewish law, if a suspect on trial was unanimously found guilty by all judges, then the suspect was acquitted. This reasoning sounds counterintuitive, but the legislators of the time had noticed that ...

(Phys.org)—According to the best current physics models, the universe should have collapsed shortly after inflation—the period that lasted for a fraction of a second immediately after the Big Bang.

(Phys.org)—Researchers have demonstrated that coating a cobalt film in graphene doubles the film's perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum ...

(Phys.org)—In organic semiconductor materials, there has always been a tradeoff between the ability to emit light and the ability to conduct a charge, as measured by the charge carrier mobility. Now for the first time, scientists ...

(Tech Xplore)—Researchers have built a locust-inspired robot that is just 5 inches (13 cm) long and weighs 23 grams, but despite its small size can jump 11 feet (3.35 m) high and cover a horizontal distance of 4.5 feet (1.37 ...

(Phys.org)—Many people are familiar with the friction enigma of two interleaved phonebooks, in which all of the pages of two phonebooks are overlapped, one by one, with the books' spines facing outward. Trying to separate ...

(Phys.org)—In a new study, physicists at Penn State University have for the first time proposed a way to test a little-understood form of quantum mechanics called nonassociative quantum mechanics. So far, all other tests ...

(Phys.org)—Typically when two magnets are brought close together, they either attract or repel each other due to interactions between their magnetic fields. In a new study, researchers have designed a 3D magnetic invisibility ...

(Phys.org)—Physicists have built a nanowire cage that blocks one or more wavelengths of light from either entering or escaping, yet allows liquids and gases to pass through the small gaps between the nanowires. The "optical ...

(Phys.org)—For the first time, physicists have performed an experiment confirming that thermodynamic processes are irreversible in a quantum system—meaning that, even on the quantum level, you can't put a broken egg back ...

(Phys.org)—Researchers have constructed a new type of nanoporous membrane that does an exceptionally good job at selectively controlling ion transport—for instance, allowing negatively charged ions to pass through the pores, ...
