In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the ...

Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The skin of lead-208 — a ...

A comet 80 miles in width is barreling toward the sun, according to data captured by NASA's Hubble Space Telescope. The comet is hurtling toward the inner solar system at 22,000 miles per hour, NASA ...

MIT scientists used radium monofluoride atom to observe electrons entering atomic nuclei, revealing new details of nuclear magnetism.

A novel experiment has revealed a phenomenon called the Bohr–Weisskopf effect in a pear-shaped nucleus in a molecule for the first time.

A team of Yale researchers discovered how a protein called Ndc1 coordinates nuclear pore and envelope assembly after cell division, an important component of understanding how cell nuclei change in ...
