Satellite telemetry, tiny geolocation tags and passive acoustic recording are providing new insights into bird migration and vital data for conservation.
Brown noise sounds like the ocean and some people say it helps them sleep. Here’s what the science actually says.

Tracking wild animals can provide lots of valuable data. New research suggests audio recordings of wild wolves can replace the typical radio collars, which can be expensive and intrusive.
Humpback whales are deterred from their migration routes by the noise of air guns used to survey the ocean floor for oil and gas deposits, a new study has found.

A recent study finds that noise from human activities is intruding into many parks and other protected areas. Creating quiet zones and noise corridors can help reduce impacts from noise pollution.
A robust technique using the wonders of digital media has helped researchers understand how threatened species like frogs are faring on our globally changing planet.
