Oceans

Over the past decade, a group of zoos and aquariums have teamed up for an unusual rescue project. They work together to save and grow threatened coral from an underwater zone off the coast of Florida. Meet a marine biologist in Colorado who’s leading an important part of that preservation work, even though she’s hundreds of miles from the ocean.

Scientists who study the deepest parts of the ocean may soon harness unusual new technology that’s being developed at CU Boulder. Researchers there fit tiny electric devices onto live jellyfish, so scientists can steer them into remote places where humans can’t easily go. We hear more about this research into robotic jellyfish.

Giant gyres of plastic in the ocean grab headlines, but it's the tiny bits of plastic that scare scientists. And they've made their way everywhere, a new study finds — including in our seafood.
