    Plastics outnumber baby fish 7-to-1 in some coastal nurseries

    Ocean slicks serve as calm, food-rich nurseries for larval fish. A new study shows that slicks also accumulate plastics, which get eaten by baby fish.

    Humpback whales use their flippers and bubble ‘nets’ to catch fish

    A study reveals new details of how humpback whales hunt using their flippers and a whirl of bubbles to capture fish.

    This year’s SN 10 enjoy the journey, not just the discovery

    Meet 10 young researchers who combine persistence and passion to make headway on science’s big questions.

    How climate change is already altering oceans and ice, and what’s to come

    A new IPCC report gives the lowdown on how climate change is already wreaking havoc on Earth’s oceans and frozen regions, and how much worse things could get.

    Climate change may be throwing coral sex out of sync

    Several widespread corals in the Red Sea are flubbing cues to spawn en masse.

    Ancient crystal growths in caves reveal seas rose 16 meters in a warmer world

    The Pliocene era cave formations on the Spanish coast of Mallorca offer hints about how oceans could respond to human-driven climate change.

    How Kilauea’s lava fed a massive phytoplankton bloom

    Kilauea’s heavy flow of lava into the ocean in 2018 added both food and heat to fuel a sudden bloom of ocean algae.

    Ocean acidification could weaken diatoms’ glass houses

    Ocean acidification may lead to smaller, lighter diatoms in seawater, which could also shrink how much carbon the tiny ocean algae can help sequester.

  9. Life

    How a newly identified bacterium saps corals of their energy

    A parasitic bacterium that preys on corals quickly reproduces when it senses more nutrients in its host.

  10. Climate

    Climate change may make El Niño and La Niña less predictable

    Atlantic Niñas and Niños have been fairly reliable bellwethers for severe El Niño and La Niña events in the Pacific. A warming world may change that.

    Southern right whale moms and calves may whisper to evade orcas

    Mother-calf whale pairs call to each other quietly to stay in touch while avoiding attracting the attention of predators, a study suggests.

    A mysterious coral disease is ravaging Caribbean reefs

    Scientists are racing to learn what’s behind a disease that’s “annihilating” whole coral species in hopes of stopping it.
