After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Scientists in the United States have made an extremely precise measurements of unstable ruthenium ...

Composite image of dwarf galaxy Markarian 71, 11 million light years from Earth. Optical and infrared observations of Mrk71 resolve a question about two methods used to measure the composition of ...

The authors do not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and have disclosed no relevant affiliations beyond their ...

Compared to scribbling mathematical expressions for entangled quantum states on a sheet of paper, producing real entanglement is a tricky task. In the lab, physicists can only claim a prepared quantum ...

In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be directly controlled and observed in real time. The achievement pushes the ...
