Metal products contain microscopic stresses that can grow into bigger problems. How engineers choose to manage these stresses makes all the difference.
Light dark photons? Dark Higgs bosons? Scientists look for signs of these weird-sounding particles in data from BaBar—an experiment designed to explain a completely different mystery.
Thin layers of diamonds have become useful tools inside the detectors at the Large Hadron Collider. They're robust enough to monitor the harsh conditions, and they can even provide incredibly precise measurements of the timing of passing particles.
