Cells in symbiotic partnership, sometimes nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways.
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.
Researchers agree it’s a long shot, but transmissible cancers could theoretically evolve into independent species. Certain weird parasites might be living proof.
Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.
The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
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.
