Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

Scientists say they have shed new light on how bacteria protect themselves from certain phage invaders -- by seizing genetic material from weakened, dormant phages and using it to 'vaccinate' ...

Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, derived from the Greek word for bacteria-eaters, or in shortened form, "phages." ...

In new research published this week in Cell Host & Microbe, a team led by Marine Biological Laboratory (MBL) scientists reveals that symbiotic bacteria often accompany single-celled protists in ...

While no single bacterium likely holds the key to managing MS, the cumulative evidence suggests that nurturing a balanced microbiome represents a promising complementary approach to conventional ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.
