Until now, tiny xenobots have been assembled by hand from frog cells according to blueprints provided by an AI. A first can now reproduce itself.
Tiny robots made from frog cells unveiled a year ago can now self-replicate. In a remarkable development, the so-called xenobots have now created a new biological organism, explains the research team led by Michael Levin of Tufts University near Boston. Until now, they had had to painstakingly assemble the "new class of living artifacts" from several hundred cells each in precision mechanical work. The ability to replicate is now a groundbreaking breakthrough on the way to being able to use the xenobots in humans one day, for example to produce insulin or repair spinal cord injuries. Moreover, the replication occurs in a way that has never been observed in nature.
AI develops artificial organisms
Xenobots were biorobots introduced in early 2020 that were based on a novel approach [1]. They initially consisted of about 500 to 1000 skin and heart muscle cells of the clawed frog (Xenopus laevis), which had been assembled by hand according to a new blueprint. This had previously been calculated by a computer algorithm, which was intended to build machines for very specific tasks. The result was not only mini-robots [2] that crawled independently on four legs through the Petri dish. Some of the specimens, which were less than a millimeter in size, were even able to transport tiny objects. For fuel, the mini-robots use the cells' reserves, which can provide energy for several days.
"Some people have said that xenobots are not organisms because they cannot reproduce, now they can," Levin now says [3]. Once again, his team has achieved this thanks to the help of algorithms. In simulations, they tried out billions of cell combinations to find out which ones could reproduce over more than one generation. The result was a kind of half torus that looks like Pac-Man with an open mouth. If you put them in a Petri dish with stem cells, they would have started to push them together - as expected - into clumps, from which new xenobots would have spontaneously formed. Up to five generations of these new round xenobots were created in this way.
The form of the xenobots is virtually their programming, explains Josh Bongard of the University of Vermont, who worked on it, to CNN. Overall, he said, this is early-stage technology and there are no practical applications for the biorobots yet. But this combination of molecular biology and artificial intelligence has a lot of potential, and not just for applications in the body. They could also collect microplastics in the oceans one day, the research team believes. There is no need to worry about self-replicating biomachines, they assure us. The small robots are biodegradable and safely stored in the laboratory. The research is also being reviewed by an ethics committee. The researchers present their work in the scientific journal PNAS [4].
