Experimental physics

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

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.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces and pressures inside a subatomic particle for the first time.

The development of attosecond pulses of light allowed researchers to explore the frame-by-frame movement of electrons.

Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.

By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.

A novel type of neural network is helping physicists with the daunting challenge of data analysis.
