Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a vital ...

An international collaboration of scientists has created the largest 3D map of our universe to date based on the first results from the Dark Energy Spectroscopic Instrument (DESI). It's an impressive ...

SANTA BARBARA, Calif. — The word “crisis” hung in the air from the very beginning of the meeting. In a room just steps from the ocean in Santa Barbara, astronomers and physicists shifted restlessly in ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental ...
