What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A ...

The core element of the experiment: a crystal containing thorium atoms. (Courtesy: TU Wien) New high-precision laser spectroscopy measurements on thorium-229 nuclei could shed more light on the fine ...

Angle of rotation: A light source (left) sends a beam of light through a topological insulator with an intrinsic magnetic field (centre), changing the direction of polarization by an angle that is ...

One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...
