An international team of researchers has solved a long-standing puzzle in quantum physics by discovering an elusive ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

This giant greedy atom can help scientists probe the reaches of ultracold atom physics. The space between an atom's nucleus and electron is usually barren. But, when an electron's orbit sits ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

Optical microscopes can help us see the microscopic world, but to use them to examine individual atoms is like measuring an ant with a measuring tape. An atom is way too smaller as compared to the ...

The Nobel Prize in physics has been awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their work looking at electrons in atoms in split-second moments. Hans Ellegren, the ...

Quantum entanglement is a phenomenon that’s as bizarre as it is fragile. Entangled particles are thought to lose this inexplicable link when exposed to outside factors. But now, physicists have ...

This calculated diffraction image shows how forked diffraction gratings shape the atoms' wave function into a vortex. (Courtesy: Science/AAAS) A wave-like property previously only seen in beams of ...

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve ...

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...
