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 ...

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 ...

The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...

Years before Robert Oppenheimer led the Los Alamos lab that developed the first nuclear weapons, physicists in D.C. thrust the world into the atomic age — inside a narrow, zigzagging tunnel running ...

In March 2018, researchers launched what looks like a white, cooler-sized fridge to the International Space Station. That heavy box houses a $100 million facility known as the Cold Atom Laboratory, ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

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 ...
