Measuring zero: scientists have lowered the previous upper limit of the neutron’s electric dipole moment by 40%. (Courtesy: IOP Publishing) For more than 60 years, physicists have been searching for a ...

Physicists have found the strongest sign yet of a fabled four of a kind. For six decades, researchers have hunted for clusters of four neutrons called tetraneutrons. But evidence for their existence ...

The building blocks of matter that have been experimentally verified are the quarks and leptons described by the Standard Model. Since the discovery of the electron in 1897, physicists have identified ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

A worldwide collaboration of scientists has announced the most precise measurement ever taken of a neutron's lifetime. How? By giving neutrons a nice long soak in an ultracold "neutron bathtub." Share ...
