A miniscule water droplet is on the move, picking up speed as it glides along a stretch of thin, flat terrain. Abruptly, it hits a rough patch - the microscopic equivalent of glass speed bumps into which the droplet settles and stops dead.

Signals can be amplified by an optimum amount of noise, but this so-called stochastic resonance is a fragile phenomenon. Experimental research shows that stochastic resonance becomes robust to variations in the signal frequency when systems have memory. This has implications in many fields of physics and energy technology.
