full of complex interactions between organisms—from microscopic bacteria, viruses, algae, and protozoa to larger organisms such as fish. Their mutual interactions, whether predation, parasitism ...

Algae on Greenland’s ice are spreading faster due to climate change. They store nutrients, darken ice, and speed up melting.

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.

Glaciers are huge white ice masses that can reflect a lot of sunlight. However, especially where the glaciers are not covered in snow and the bare ice is exposed, they sometimes have dark patches.

But recently attention has turned to the nutritional and environmental potential of their microscopic ... bacteria are the ones producing the vitamin B12, which is then taken up by the algae.

Which explores microscopic lifeforms in ... Each strand is an oscillating colony of bacteria. These diatoms are in another NYC pond. They're cells of algae inside tiny glass houses and we really ...

The researchers tested the algae in mice with a severe form of pneumonia caused by Pseudomonas aeruginosa bacteria. Known as ventilator-associated pneumonia (VAP), the potentially fatal infection is ...

Researchers found that Greenland’s ice algae store phosphorus, allowing them to expand and darken ice surfaces, reducing reflectivity and accelerating melt rates. As climate change exposes more ice, ...

Shallower oceans would fare little better. Corals, which depend on microscopic algae and a surprisingly diverse collection of bacteria, would become weak and vulnerable. Their mighty reefs would ...

Algae, microscopic aquatic plants, are a natural part of any aquatic ecosystem. Most algae are harmless, but under the right conditions certain types of algae can pose health risks. People or ...
