'Exceptional points' give rise to counterintuitive physical effects
No matter whether it is acoustic waves, quantum matter waves or optical waves of a laser—all kinds of waves can be in different states of oscillation, corresponding to different frequencies. Calculating these frequencies ...

Modular acoustic filters simplify design of mufflers, musical instruments, audio tags
Designing acoustic filters that can block out a certain sound or produce a certain pitch can be hit or miss, but researchers have discovered a way to predict acoustic qualities 70,000 times faster than current algorithms, ...

Pencil test for pipeline cracks
It is impossible to see when the "lead" in a pencil cracks within the pencil, but an acoustic sensor can "hear" the change in the way the pencil vibrates. Now, researchers in China have reported in the International Journal ...

How fisheries impact behavioural evolution in Atlantic cod
As seen in other animal species, fish individuals tend to react differently to a new situation. In the case of human harvest, the boldest individuals are more likely to get caught, leaving only the fearful and cautious ones ...
