All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start.

What separates animals, plants, fungi and even amoebas from bacteria? Well, there's one feature that no longer universally makes us distinct, thanks to a new study that redefines what it means to ...

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 ...

Mitochondria are membrane-bound components within cells that are often described as the cells' powerhouses. They've long been considered as essential components for life in eukaryotes, the group ...

Deep in hydrothermal vents beneath the Arctic Ocean, scientists have discovered an organism that sheds fresh light on the evolutionary link between simple and complex cellular life. The microbe and ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

In a significant breakthrough for biological engineering, scientists have created an artificial eukaryote chromosome and inserted it into living brewer’s yeast cells (Science 2014, DOI: ...
