Tiny relatives of our cellular ancestors reshape long protrusions within minutes and pull themselves across surfaces using ancient actin machinery.

A new review argues that transcription termination signals operate as distinct grammars across bacteria, archaea and ...

A teeny-tiny archaea with one of the smallest genomes ever discovered is pushing the limits of what it means to be alive.

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

RNA therapeutics open up new possibilities for the targeted and precise treatment of diseases. To ensure that RNA molecules ...

Led by Jizhong Zhou, Ph.D., the director of the Institute for Environmental Genomics at the University of Oklahoma, an international research team conducted a long term experiment that found that ...

Single-celled organisms called archaea occupy their own branch on the tree of life, like bacteria, but we know a lot less about them. Like bacteria, archaea also don't have a nucleus, and have ...

Life is not possible without nitrogen. There are many ways for organisms to acquire nitrogen. For example, humans eat proteins for their high nitrogen content. Most microorganisms take up nitrogen ...

In the late 1970s, a new branch was added to the tree of life, and archaea joined bacteria and eukarya, as domain classifications. Archaea and bacteria are both simple forms of cells called ...

All multicellular organisms harbor an unimaginably large number of microorganisms in and on their bodies. The microbiome, i.e. the totality of these microbes, forms a functional, symbiotic unit with ...

Single-celled archaea microbes pack their DNA into flexible coils that expand and stretch much like a Slinky does. This kind of molecular gymnastics had never been seen before in other organisms and ...
