Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.
In the “underground economy” for soil nutrients, fungi strike hard bargains and punish plants that won’t meet their price.
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
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.
Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.
Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
How does evolution select the fittest “individuals” when they are ecosystems made up of hosts and their microbiomes? Biologist debate the need to revise theories.
