Don’t be misled by the bloodthirsty names of immune cells. Mounting research shows that the cells also fine-tune tissues and help the body heal.
The glial cells of the nervous system have been eclipsed in importance by neurons for decades. But glia are turning out to be central to many neurological functions, including pain perception.
To scientists’ surprise, blended mixtures of cytoplasm can reorganize themselves into cell-like compartments with working structural components.
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.
