Nuclear fission has powered our world and medical advancements for decades. What exactly happens when an atom's nucleus splits into two parts?

A simulation by US theoretical physicists has provided the first fully microscopic characterization of the moment an atom ...

What’s the safest place to store important information? No, it’s not your external hard drive or some secret cloud ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so ...

Dark matter’s interactions with other matter is impossible to perceive except when it collides with the nucleus of a visible ...

the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up being shared by the atoms in a region around ...

Mitochondria divide to share the load when nutrients are scarce — plus, how smashing atomic nuclei together helps identify their shapes.

Nuclear fission—when the nucleus of an atom splits in two, releasing energy—may seem like a process that is fully understood.

Researchers have long been hunting for a way to make the elusive elements more stable so they can be better studied.

Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

Fine tuning an experimental setup improved a detector's sensitivity to neutrinos and perhaps eventually dark matter—two ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
