Study finds semiclassical gravity counterintuitive, but on the horizon of testability
Quantum mechanics could make money, credit cards, and tickets immune to fraud
Stretchable graphene transistors overcome limitations of other materials
Researchers unravel mysteries of spider silk
(Phys.org)—Scientists at Arizona State University are celebrating their recent success on the path to understanding what makes the fiber that spiders spin – weight for weight - at least five times as ...
Physicists investigate structural properties of spider webs
Materials theory combines strength, stiffness and toughness of composites into a single design map
Mother-of-pearl, the iridescent layer in the shells of some mollusks, inspired a Rice University study that will help scientists and engineers judge the ultimate strength, stiffness and toughness of composite ...
Consider the 'anticrystal'
(Phys.org) —For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent ...
Atomic placement of elements counts for strong concrete
Even when building big, every atom matters, according to new research on particle-based materials at Rice University.
Squeezable nano electromechanical switches with quantum tunneling function
A longstanding problem in designing nanoscale electromechanical switches is the tendency for metal-to-metal contacts to stick together, locking the switch in an "on" position. MIT electrical engineering graduate ...
Using light to control light: Engineers invent new device that could increase Internet download speeds
(Phys.org)—A team of scientists and engineers at the University of Minnesota has invented a unique microscale optical device that could greatly increase the speed of downloading information online and reduce ...
Quantum computing moves forward
New technologies that exploit quantum behavior for computing and other applications are closer than ever to being realized due to recent advances, according to a review article published this week in the ...
A robot that runs like a cat (w/ Video)
Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL's 4-legged 'cheetah-cub robot' has the same advantages as its model: It is small, light and fast.
Physicists use geometry to understand 'jamming' process
(Phys.org) —University of Oregon physicists using a supercomputer and mathematically rich formulas have captured fundamental insights about what happens when objects moving freely jam to a standstill.
Supercomputers reveal strange, stress-induced transformations in world's thinnest materials
(Phys.org) —Interested in an ultra-fast, unbreakable, and flexible smart phone that recharges in a matter of seconds? Monolayer materials may make it possible. These atom-thin sheets—including the famed ...
