Elephant songs

By Stephen Ornes / August 20, 2012

Elephants sometimes communicate with sounds below the range of human ears. Researchers recently found that air rushing through the larynx can create the superlow sounds. Credit: Angela S. Stoeger

Scientists figure out how elephants make their low, low rumble

No more bubble trouble

By Stephen Ornes / August 6, 2012

Bottlenose dolphins can tell the difference between noisy echoes bounced off of bubbles and other echoes, including those bounced off of prey. Now scientists have figured out a way to tell apart the noises, too. Credit: Emma Jugovich, NOAA

Dolphin’s clicks help scientists sort through confusing underwater noises

Underwater Racket

By Emily Sohn / February 2, 2011

As more ships traverse the oceans, the volume of sound traveling underwater is increasing. This change can affect humpback whales and other residents who use sound in their daily lives. (miblue5/iStock)

The oceans are getting louder, and scientists want to know what that means for marine residents
