Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.
Some viruses can replicate without infecting any one cell with all their genes.
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.
New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many.
Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
Neither animal, plant, fungus nor familiar protozoan, a strange microbe that sits in its own “supra-kingdom” of life foretells incredible biodiversity yet to be discovered by new sequencing technologies.
A newly discovered mechanism may enable viruses to shuttle genes between bacteria 1,000 times as often as was thought — making them a major force in those cells’ evolution.
Maria-Luiza Pedrotti is illuminating the unseen worlds of plastic-eating bacteria that teem in massive ocean garbage patches.
