Put simply, a virus does not replicate or function independently. So by the biological definition, a virus cannot be categorized as a living organism.

(Archaea are microorganisms that define the limits of life on Earth.) " Sukunaarchaeum is not a virus, but a highly streamlined cellular organism," Nakayama said.

It is like a virus—typically not considered "living" organisms—in that it has a tiny genome and is totally dependent on its ...

In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to be alive. Nestled inside a tiny plankton cell, researchers found a ...

The team at the Medical Research Council’s Laboratory of Molecular Biology calls their creation Syn57. It is a synthetic ...

Viruses typically aren’t considered ‘alive,’ as many core biological functions are outsourced to their hosts. But a newly discovered organism appears to straddle the line between virus and cell.

Now, researchers have found that a family of related proteins is used to fight viruses in organisms ranging from bacteria to humans.
