"We can't break down sucralose, and a lot of microorganisms can't break it down, either, because it's a really tough molecule..."

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

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

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

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

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

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.

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

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