More Americans are now eligible for compensation for health problems linked to radiation exposure from the atomic weapons ...

This “proton radius puzzle” suggests there may be something fundamentally wrong with our physics models. And the researchers who discovered it have now moved on to put a muon in orbit around ...

The radius of a proton, he found, was about 0.879 femtometer—about one ten-billionth the size of a droplet of mist and square in line with previous measurements.

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

The atom bomb was one of the defining inventions of the 20th Century. So how did science fiction writer HG Wells predict its invention three decades before the first detonations, asks Samira Ahmed ...

Atom Computing is now using the system internally and plans to open it up for public use next year. The system has moved from a 10×10 grid to a 35×35 grid, bringing the potential sites for atoms ...

The award-winning long-exposure photograph captures a positively charged atom suspended in an ion trap. An image of a single positively-charged strontium atom, held near motionless by electric fields.

Rutherford made a series of discoveries about the nature of atoms and, working with colleagues Hans Geiger and Ernest Marsden, presented a planetary model of the atom in 1911. In it, he laid out ...
