Very James Bond

Well, this sounds somewhat creepy, and reminds me of the nanobot menace that featured in No Time to Die:

The robots are alive, and now they can reproduce.

That’s not a sequel to “The Terminator.” It’s the result of new research showing that microscopic life-forms made of frogs’ stem cells can self-replicate in a way not seen in other animals or plants.

These xenobots, named for the African frog Xenopus laevis from which they are made, could already move around, display collective behavior and heal themselves. A study released Monday suggests that the cell clumps also can be engineered to sustain themselves for at least five generations.

“There’s nothing theoretical that would stop us from making these out of human cells,” said Sam Kriegman, an author of the study published in the journal Proceedings of the National Academy of Sciences (PNAS). “They could perform useful work inside of human bodies in places were traditional robots can’t go because our bodies detest even the smallest amount of metal.”
