Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Baryons, composite particles made up of ...

There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the ...

Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do with 800 square feet of scintillator from an old physics experiment? Cut it up and give it to high ...
