“Demonstration of a large scale laser beam like this is a kind of holy grail for laser physicists,” said Prof Wieslaw Krolikowski of the Laser Physics Center and Texas A&M University at Qatar, Doha, who is the senior author of a paper published in the journal Nature Photonics. The team’s

Ds3*(2860)ˉ is a meson that contains a charm anti-quark and a strange quark. The subscript 3 denotes that it has spin 3, while the number 2860 in parentheses is the mass of the particle in the units of MeV/c2. The value of 2,860 MeV/c2 corresponds to approximately 3 times the mass of the proton.

Every year, around about this time, thousands of European robins escape the oncoming harsh Scandinavian winter and head south to the warmer Mediterranean coasts. How they find their way unerringly on this 2,000-mile journey is one of the true wonders of the natural world. For unlike many other

Raindrops have been caught breaking the speed limit. Using drizzle detectors, researchers discovered tiny raindrops falling more than 1.3 times as fast as terminal velocity, the speed at which air resistance cancels out gravitational pull. The cause of the drops’ super speed remains unknown, but

Many U.S. fusion scientists are blasting a report that seeks to map out a 10-year strategic plan for their field, calling it “flawed,” “unsatisfactory,” and the product of a rushed process rife with potential conflicts of interest. One result: Last week, most members of a 23-person government
