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 ...

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

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.

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 ...

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.

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 ...

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 ...

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique. Seeing inside the tiniest bits of matter is a ...

Atoms are so small that it’s almost impossible to see them without microscopes.; But now, an award-winning picture of an atom shows a single particle in an electric field—and you can see it ...
