Electrons have been seen uniting into entities with fractions of electric charge, this time without a magnetic field coaxing them into it.

Particle physicists in search of the next theory of reality are consulting a mathematical structure that they know will never fail: a table of possibilities known as the S-matrix.

Alex Sushkov is updating an old technology with new quantum tricks in hopes of sensing the magnetic influence of dark matter.

Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.

Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms.

The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. The hidden culprit? Magnetic activity.

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles — though not yet those of our universe.

Physicists and cosmologists will have a new probe of primordial processes when Europe launches the Laser Interferometer Space Antenna (LISA) next decade.

Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off moons and planets.
