A team of scientists from the SETI Institute, UC Davis and the Alaska Whale Foundation had a close encounter with a non-human (aquatic) intelligence.

Shellfish, along with other marine organisms, are facing a crisis, one that affects the integrity of their shells. As carbon dioxide emissions increase in the atmosphere, so too does the amount of carbon dioxide absorbed by our oceans, leading to ocean acidification. Graduate student Meghan Zulian has devoted her doctoral studies to understanding how ocean acidification, and more broadly climate change, affects culturally, economically and ecologically important shellfish, including abalone.

A unique ocean-going restoration effort is just getting underway along the Sonoma Coast and its goal is to rescue an underwater forest that's critical to marine life.

As winter approaches, many species of animals — from bears and squirrels to parasitic wasps and a few lucky humans — hunker down for some needed rest.

Under the right living arrangement, disease-resistant corals can help “rescue” corals that are more vulnerable to disease, found a study from the University of California, Davis, that monitored a disease outbreak at a coral nursery in Little Cayman, Cayman Islands.
