An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the ...

Physicists have developed a highly precise and ultra-sensitive atomic clock based on ytterbium, which ...

Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter ...

If an atomic physicist like Nathan Lundblad could slip the surly bonds of Earth’s gravitational pull, what kind of experiment would he dream up? About a decade ago, that very question was posed to ...

New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new ...

For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...
