Phys.org / Scientists rediscover self-healing silicone mechanism from the 1950s
(PhysOrg.com) -- Research in self-healing organic polymers has grown recently, but one simple self-healing mechanism from more than 60 years ago has been nearly forgotten until now. Using this mechanism, which is called “siloxane ...
Phys.org / Iridescence and superhydrophobicity combined on one surface
(PhysOrg.com) -- Scientists have combined two properties on a single piece of graphene oxide that don’t usually go together: iridescence (resulting in a rainbow-hued appearance) and superhydrophobicity (causing low-contact ...
Phys.org / Serial killing follows predictable pattern based on brain activity
(PhysOrg.com) -- Over a period of 12 years, Andrei Chikatilo murdered at least 53 people before being arrested in Rostov, Russia, in 1990. While Chikatilo’s killings, mainly of women and children, may have been senseless, ...
Phys.org / Proposed experiment offers new way to generate macroscopic entanglement
(PhysOrg.com) -- In the development of quantum information processing, one of the key requirements is achieving quantum entanglement. But recently, physicists have been investigating other forms of quantum correlations besides ...
Phys.org / Spandex manufacturer makes elastic electrical cable (w/ video)
(PhysOrg.com) -- Japanese company Asahi Kasei Fibers, which manufactures spandex and other textiles, has applied its knowledge of stretchable materials to make stretchable elastic power and USB cables.
Phys.org / Award-winning energy harvester brings practical applications closer
(PhysOrg.com) -- Although the idea of harvesting ambient energy from the environment and using it to generate electricity is alluring, most of the technology so far is capable of generating only very small amounts of power ...
Phys.org / Four reasons why the quantum vacuum may explain dark matter
(PhysOrg.com) -- Earlier this year, PhysOrg reported on a new idea that suggested that gravitational charges in the quantum vacuum could provide an alternative to dark matter. The idea rests on the hypothesis that particles ...
Phys.org / Battery electrode's 40,000 charge cycles look promising for grid storage
(PhysOrg.com) -- While researchers continue to improve solar and wind energy technologies, having a battery that can store the energy until it’s needed by the grid is another critical component for using renewable energy ...
Phys.org / Robotic boats to travel across Pacific Ocean
(PhysOrg.com) -- Last Thursday, November 17, four unmanned Wave Gliders left the coast of San Francisco and began a 300-day journey across the Pacific Ocean. The vehicles, which are self-propelled and remotely piloted, will ...
Phys.org / Light-controlling artificial diamond structures could lead to optical computers
(PhysOrg.com) -- In an effort to make computer chips even faster than those of today, many researchers have recently been investigating the possibility of optical computing. In an optical computer, information is encoded ...
Phys.org / Rossi's E-Cat gets first customers, but questions remain
(PhysOrg.com) -- Italian scientist Andrea Rossi has spent the past year giving demonstrations of a device that he claims can generate large amounts of energy due to a little-understood nuclear process. His latest demonstration, ...
Phys.org / 'Cambridge Nights': a late night show for scientists
(PhysOrg.com) -- While it’s not uncommon to see scientists on TV, most of the time it’s just for a few minutes on the news to comment on a recent event or major discovery. A new late night show called “Cambridge ...
Phys.org / Researchers find a country's wealth correlates with its collective knowledge
(PhysOrg.com) -- What causes the large gap between rich and poor countries has been a long-debated question. Previous research has found some correlation between a nation’s economic prosperity and factors such as how ...
Phys.org / 'Smart DC' cuts electricity costs by using direct current electricity (w/ video)
(PhysOrg.com) -- As the use of computers and mobile electronics continues to rise, so does the energy wasted by the devices’ AC/DC adaptors when converting AC from wall sockets to DC for the devices. The London-based ...
Phys.org / US Army purchases robotic scouts (w/ video)
(PhysOrg.com) -- By being the first to scout out an unknown building or peek over a wall, a small dumbbell-shaped robot will be taking over some of the riskiest tasks in the US Army. The robot’s maker, ReconRobotics, ...
