For Real: Frog Skin Cells Turned Themselves Into Living Machines After Scientists Removed Them From Embryos
Using blobs of skin cells from frog embryos, scientists have grown creatures unlike anything else on Earth, a new study reports. These microscopic “living machines” can swim, sweep up debris and heal themselves after a gash.

Scientists often strive to understand the world as it exists, says Jacob Foster, a collective intelligence researcher at UCLA not involved with this research. But the new study, published March 31 in Science Robotics, is part of a “liberating moment in the history of science,” Foster says. “A reorientation towards what is possible.”

In a way, the bots were self-made. Scientists removed small clumps of skin stem cells from frog embryos, to see what these cells would do on their own. Separated from their usual spots in a growing frog embryo, the cells organized themselves into balls and grew. About three days later, the clusters, called xenobots, began to swim.

Less than 50%:

And that process happens fast. “This isn’t some sort of effect where evolution has found a new use over hundreds of thousands of years,” Levin says. “This happens in front of your eyes within two or three days.”

Xenobots have no nerve cells and no brains. Yet xenobots — each about half a millimeter wide — can swim through very thin tubes and traverse curvy mazes. When put into an arena littered with small particles of iron oxide, the xenobots can sweep the debris into piles. Xenobots can even heal themselves; after being cut, the bots zipper themselves back into their spherical shapes.

Holy cow, OP! Great find!

Come on, people -- this is a fascinating development in the field of biology!

I can't understand how this thread hasn't gotten more traction. I'm going to pin request it again

A matrix of such piles. That sounds like an... antenna?
