Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...

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 ...

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom.

Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up. When you purchase through links on our ...

Physicists have studied a rare molecule to look at how magnetism is distributed within a radioactive nucleus for the first time. The rules of nature don’t, generally speaking, change. If you toss a ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed an elliptical galaxy known as ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...
