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 ...

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 ...

BOULDER, Colo., Sept. 26 (UPI) --The emergence of the first eukaryotes is a poorly understood episode of early evolution. Newly unearthed Tappania plana fossils suggest early iterations of the ancient ...

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 ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important for ...

In our cells, 6 feet (1.8 m) of DNA gets crammed into chromosomes that fit inside a 6-µm-wide nucleus. The proteins that help pack up that genetic material are histones, which act as spools around ...

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: ...

Mitochondria have long been thought to be the normal engine of a eukaryotic cell and one that was essential for the survival of fungi, plants, animals and other organisms. Now, a single-cell microbe ...

A rapid method for the simultaneous extraction of RNA and DNA from eukaryote plankton samples was developed in order to discriminate between indigenous active cells and signals from inactive or even ...
