At universities and startups around the globe, researchers are searching for microbes that could be used as food.

In herU.K. lab, Onyeaka is growing Chlorella vulgaris, a green single-celled algae about 2 to 10 microns in diameter — roughly the width of a strand of spider silk. She and a graduate student ...

Europe's water bodies are in poor condition: more than half of them are heavily polluted with chemicals. This is hardly ...

Giant viruses inhabiting the oceans infect, among others, various species of single-celled algae, photosynthetic organisms that are responsible for about half of the Earth’s oxygen production ...

Many phytoplankton are microscopic, and they range from single-celled algae to bacteria to protists, which aren’t plants or animals. One thing they all have in common: They require sunlight.

The cactus-shaped algae are unique in many respects, Lin says. They grow as single cells with many nuclei and are relatively enormous compared to other single-celled organisms, reaching sizes of ...

So far researchers are trying to find the best strand of the single-celled plant that is most effective. Algae ingests CO2 and releases oxygen, but it's also laden with oils that can be used to ...

Stentors form a symbiotic relationship with algae that gives them a greenish-blue color. The algae feed on stentors’ waste products while sharing some nutrients with their host. Stentors are among the ...

Large swaths of orange, green, or most often, watermelon-red snow is a sign of a thriving microscopic community dominated by single-celled algae. Watermelon snow is not new: It appears in Captain John ...

Sailors and fishermen are well aware of the effects of P. lunula algae, which are single-celled organisms that can cause the sea to glow blue, even though they may not have heard of them.
