Swarms of tiny living robots can self-replicate in a dish by pushing loose cells together. The xenobots – made from frog cells – are the first multicellular organisms found to reproduce in this way.

A cell nucleus reconstituted in vitro in Xenopus laevis (African clawed frog) egg extract. Left image shows a fluorescence image where DNA has been stained and right image shows a density map of the ...

Xenobots—living robots made from the stem cells of the African frog (Xenopus laevis)—had already impressed researchers by moving, healing themselves, and even spontaneously piling up debris that was ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...
