NEW YORK (AP) — Scientists have detected cosmic waves that sound like birds chirping in an unexpected place. These bursts of ...

A global study by UW–Madison researchers reveals how habitat, geography, body size, and beak shape influence bird sounds.

Using high-frequency sound waves to make tunable optical filters, modulators and Q-switches is a well-established and convenient technological solution for many applications, reports Neil Savage.
