For more than half a decade, the Majorana Collaboration, a large consortium of researchers from different universities worldwide, have been trying to observe neutrinoless double-beta decay, one of the rarest forms of radioactive ...
In 1895, Wilhelm Röntgen discovered X-rays and used them to image the bones in his wife's hand, kicking off a revolutionary diagnostic tool for medicine. Now two of NASA's X-ray space telescopes have combined their imaging ...

Physicists worldwide are trying to detect dark matter (DM) particles and their interactions with visible matter using various strategies and detectors. As these particles do not emit, reflect or absorb light, they have so ...
Over the course of the 20th century, physicists have discovered numerous elementary particles. The largest family of these particles are the so-called hadrons, subatomic particles that take part in strong interactions.
Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle ...

Deep inside all matter in the universe, electrons are buzzing around and behaving as if they are twirling around on their axes like spinning tops. These "spinning" electrons are fundamental to quantum physics and play a central ...
