(Phys.org)—Moses Chan, co-author of a paper published in 2004 describing work that resulted in claims of the discovery of supersolid helium, has now co-authored another paper, published in Physical Review Letters, describing ...
(Phys.org) -- Last year, astronomers discovered a quiescent black hole in a distant galaxy that erupted after shredding and consuming a passing star. Now researchers have identified a distinctive X-ray signal observed in ...

(PhysOrg.com) -- Scientists using slow-motion movie cameras have been trying to discover the physics behind the "wet dog shake."
A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done ...
