Phys.org / Experiments show wild fish can recognize individual divers

For years, scientific divers at a research station in the Mediterranean Sea had a problem: at some point in every field season, local fish would follow them and steal food intended as experimental rewards. Intriguingly, these ...

Phys.org / Quantum billiard balls: Digging deeper into light-assisted atomic collisions

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their nuclei—has a lot to say about how they bounce off each other. This is especially true for atoms ...
