    Algae could be key for better plant-based foods

    Lots of plant-based foods have the flavor right but the texture wrong. New research finds that algae could help improve the "mouthfeel."

    How to raise ‘lawn mowers of the reefs’ in the lab

    Researchers are trying to restore long-spined sea urchins, which eat algae that could otherwise smother reef ecosystems and kill corals.

    Heat worsens viral attacks on algae in corals

    During marine heat waves, viruses may increase their attacks on the symbiotic algae that give reef-building corals their amazing colors.

    Tiny chalk disks in ocean are ‘catalysts for death’

    The circular, chalky plates of marine algae E. huxleyi can act as catalysts for viral infection and are key to Earth's carbon cycle.

    Nutrient loading could spell trouble on Atlantic coast

    New research predicts nutrient loading, which puts certain areas of the US at heightened risk of harmful algal blooms.

    Siberian wildfire may have amped up Arctic algal bloom

    Smoke from a Siberian wildfire may have transported enough nitrogen to parts of the Arctic Ocean to amplify a phytoplankton bloom, researchers say.

    Sinking ‘marine snow’ aids oceans in locking up CO2

    New research digs into exactly how the ocean's "biological pump" for carbon dioxide works. It turns out the constant sinking of underwater "snow" is key.

    Algae sex could save corals from climate change

    Researchers have discovered that algae called dinoflagellates can reproduce through sex. The finding could help protect corals from climate change.

    Aussie wildfires fed giant algae blooms thousands of miles away

    Iron in smoke and ash from wildfires can "fertilize" the oceans, providing nutrients for algae blooms that then may suck up carbon, research indicates.

  • A variety of different kinds of corals

    Corals may co-evolve with the algae inside them

    Microscopic algae may evolve in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another's needs, according to a new study.
