In crowded environments, more robots don’t always mean faster results—in fact, too many can bring everything to a standstill.

How do you stop robotic traffic jams? Researchers found that adding "noise" or randomness to robot paths optimizes swarm efficiency, proving that swarms don't need central AI to avoid gridlock.

A laser is usually constructed from two basic elements: a material that provides optical gain through stimulated emission and an optical cavity that partially traps the light. When the total gain in ...
