A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound ...

Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances. Not only can we not see or smell it, but traditional gas sensors have ...
