For the first time, nuclear physicists have made precision measurements of a short-lived radioactive molecule, radium monofluoride (RaF). In their study published in the journal Nature Physics, the ...

One of the goals of the James Webb Space Telescope, launched in 2022, is to make infrared observations of the composition of distant galaxies in the first billion years of the universe. The new ...

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 ...

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 ...
