Nature through the looking glass Handedness—and the related concept of chirality—are double-sided ways of understanding how matter breaks symmetries.

Parking the LHC proton train Particle accelerators like the LHC require intricate beam dump systems to safely dispose of high-energy particles after each run.

The neutrino painter In this stop-motion video, Symmetry writer Zack Savitsky imagines an artist whose supplies have taken on some of the properties of neutrinos.

A robot ballet Humans and robots work together in a carefully choreographed dance for the Mu2e experiment.

How big is a neutron star? Astrophysicists are combining multiple methods to reveal the secrets of some of the weirdest objects in the universe.

A bit of MAGIC The MAGIC telescope’s first observation of a gamma-ray burst gave astronomers surprising new insight into the phenomenon.

Long-lived particles get their moment Scientists on experiments at the LHC are redesigning their methods and building supplemental detectors to look for new particles that might be evading them.
