A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum computers, potentially

Nuclear reactors may go dark, but their fuel continues producing a faint antineutrino “glow” long after shutdown. Researchers have now detected that residual signal for the first time, finding it closely matched predictions

Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal everything from rare stars

JWST has uncovered surprising clues that Neptune’s strange inner moons may be the wreckage of an ancient cosmic catastrophe. Researchers detected clay-like minerals on Larissa, Galatea, and Neptune’s rings that form in the

Astronomers using the James Webb Space Telescope have discovered a bizarre object from just a few hundred million years after the Big Bang that looks like an enormous star but shines far too

TL;DR: LLM predictions can stand in for human outcomes in A/B tests, but only by assumption, not by design

Researchers have found a clever new way to map a part of Earth’s upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in

Physicists have found a new way to peer inside one of matter’s most elusive quantum states: the Wigner crystal, where electrons stop behaving like independent particles and organize into a crystal-like pattern. By
