Pair of noted physicists contemplate future of cosmology after detection of primordial gravitational waves
Solution to two long-standing mysteries of cuprate superconductivity found
Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by ...
Researchers build acoustic tractor beam
Astronomers harness the galaxy's biggest telescope to make most precise measurement of spinning star
(Phys.org) —An international team of astronomers has made a measurement of a distant neutron star that is one million times more precise than the previous world's best.
Optical traps on chip manipulate many molecules at once
(Phys.org) —Optical trapping, a technique for studying single molecules, is traditionally delicate, requiring special equipment and a soundproof room, with data collected one molecule at a time.
Newly identified 'universal' property of metamagnets may lead to everyday uses
(Phys.org) —A new physics discovery made by a University of Virginia-led team may lead to more efficient refrigerators, heat pumps and airport scanners, among many possible uses –perhaps within a decade.
Device turns flat surface into spherical antenna
By depositing an array of tiny, metallic, U-shaped structures onto a dielectric material, a team of researchers in China has created a new artificial surface that can bend and focus electromagnetic waves ...
Scientists reconstruct ancient impact that dwarfs dinosaur-extinction blast
(Phys.org) —Picture this: A massive asteroid almost as wide as Rhode Island and about three to five times larger than the rock thought to have wiped out the dinosaurs slams into Earth. The collision punches ...
Field study shows possibility of deflecting seismic waves around desired geologic surface areas
Groundbreaking optical device could enhance optical information processing, computers
At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. ...
Physicists split and collide ultracold atom clouds (w/ Video)
Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds ...
New system could provide first method for filtering light waves based on direction
Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color ...
Researchers suggest changes to theories regarding neutron star crust structure
Researchers see Kelvin wave on quantum 'tornado' for first time
A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process ...
