Invisibility cloaks can make objects invisible not just to light in the visible part of the spectrum, but to many other physical excitations. These include acoustic waves, matter waves, heat flux, and infrared or ultraviolet ...
(Phys.org) —In an atom laser, millions of individual atoms propagate through space with minimal spreading, just like photons propagate in a coherent photon laser beam. Although both types of lasers are similar, atom lasers ...
(PhysOrg.com) -- Researchers from the Nichia Corporation in Tokushima, Japan, have set an ambitious goal: to develop a white LED that can replace every interior and exterior light bulb currently used in homes and offices. ...
Researchers from the Helmholtz Centre Berlin, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, have for the first time observed magnetic monopoles and how they emerge in a real material. They ...

Scientists studying sunspots have found important clues about magnetic features in their decay that will help understand the evolution and real origin of these mysterious magnetic phenomena. The findings are published in ...
Using the Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, astronomers have inspected an ultracompact ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have inspected single-pulse behavior of a rotating radio transient (RRAT) known as PSR J0628+0909. Results of the study, published ...
To solve a long-standing puzzle about how long a neutron can "live" outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. ...
