A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the ...

It is bright yellow, can creep along at a speed of up to 4 centimeters (1.6 inches) per hour, can solve problems even though it doesn't have a brain and can heal itself if it is cut in two. Meet the ...

During a tour of the Marine Biological Laboratory in Woods Hole, Massachusetts, Corey Allard noticed something strange: fish using six leg-like appendages to "walk" around the bottom of their tank.

We typically think of evolution as progressing in one direction, with a species getting “better” and “better” as it goes. But evolution is far more complex than that, as has recently been illustrated ...

The organism also has unique characteristics usually associated with protists and amoebas, two different branches. This left researchers wondering where the microorganism fits into the tree of life.

Many cells can use oxygen or nutrients to generate fuel, and the process is similar in many organisms that use an electron transport chain. But scientists have found that in a tiny organism, things ...

Hiding underneath the Arctic sea ice, researchers claim that it discovered rare new species that take in hydrothermal plumes from underwater volcanoes to survive. These new organisms excited the ...

The European Space Agency (ESA) just launched brainless bits of slime mold to the International Space Station to study how the single-celled organism’s behavior is affected by microgravity. The ...

Cross-section of a cell of the microalga Prorocentrum cordatum. The nucleus with the chromosomes is on the right. A single barrel-like chloroplast takes up 40 percent of the cell volume. What are the ...
