This creature blurs the line between viruses and cells, exhibiting remarkable characteristics that push the boundaries of ...

A recent breakthrough in the world of microscopic life has scientists reevaluating the boundaries of cellular existence.

In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to ...

Single-celled organisms called archaea aren't generally thought to cause human disease, but one species has been implicated in colorectal cancer ...

Scientists have discovered Sukunaarchaeum mirabile, a unique archaeon residing within marine plankton, challenging traditional definitions of life. Th ...

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like this one ...

Archaea are a distinct domain of life—along with bacteria and eukaryotes (i.e., organisms with a cell nucleus such as animals, plants and fungi).

Yet, archaea are found across diverse environments, from oceanic plankton to the human microbiome. Despite their superficial similarity to bacteria, their genetic makeup has long suggested a closer ...

This challenges the long-standing three-domain model of life that separates bacteria, archaea, and eukaryotes. Findings from Recent Studies According to a study published in Cell, researchers at ETH ...

Defense systems found in all complex life, including the human body, came from primeval microbes known as 'Asgards.' ...

Archaea, key players in the human microbiome, are linked to various diseases but their pathogenic potential remains speculative. This study highlights their role in conditions like periodontitis ...
