A major study shows complex cells evolved gradually in an oxygen-poor world, challenging long-held assumptions about life’s ...

Complex life, eukaryotes, traces its origins to a shared ancestor among the Asgard archaea, reshaping our understanding of ...

As eukaryotic cells started to form, eukaryotic traits may have emerged in early cells about one billion years before the ...

With protruding appendages that each end in an orb, Solarion arienae vaguely resembles a cartoon Sun or a retrofuturistic ...

Eukaryotic cells grow and divide through a specific series of cellular events. These events are tightly controlled, ensuring that the resultant daughter cells are free of DNA errors, and subject to ...

Oliverio and fellow Syracuse microbiologist Beryl Rappaport discovered the organism at Lassen Volcanic National Park in ...

The sun has just set on a quiet mudflat in Australia’s Northern Territory; it’ll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning ...

The discovery that a group of cell-infecting bacteria lived roughly 2 billion years ago stirs a longstanding controversy around which came first: phagocytosis or mitochondria. The ability of one cell ...

This study shows that vacancy-engineered MoS₂ nanoflowers drive mitochondrial biogenesis in human mesenchymal stem cells by ...

Prokaryotes are ancient, simple forms of life that include bacteria and archaea. These cellular life forms lack membrane-bound organelles. Those organelles, which include the nucleus and the ...

Researchers from Tokyo Metropolitan University have successfully determined the high-resolution, three-dimensional structure of proteins inside living eukaryotic cells. They combined "in-cell" nuclear ...

All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their ...
