Cleaner fish feed on the parasites that live on other fish. Studying communication between cleaner fish and their clients may help employ them in salmon farms, which can be plagued by parasites.

By measuring how and when elephant seals sleep, researchers were able to figure out how elephant seals change their risk-taking behavior as they gain weight.
Groundwater was once thought to buffer streams from warming, but an inexpensive new technique shows streams fed by shallow groundwater may be just as susceptible as those without.
Research suggests that the name of a product affects our perceptions of it – before we have even tried it.

De-icing salts help us get around in winter, but they corrode cars, crack roads and contaminate rivers and lakes. Scientists are working to develop better options by imitating natural antifreezes.

Fish farms feed millions of people around the world, but they also consume a lot of fish that are dried or ground up to make aquafeed. Researchers are developing more sustainable alternatives.

While humans domesticate plants and animals, these relationships are surprisingly rare in other species. Our new study found a species of fish that appears to have domesticated a kind of tiny shrimp.
The Pacific Ocean produces oxygen, helps regulates the weather, provides food and livelihoods. It’s a place of fun, solace and spiritual connection. But its delicate ecology is under threat.
