Meet the xenobot: world's first living, self-healing robots created from frog stem cells

(CNN) Scientists have created the world's first living, self-healing robots using stem cells from frogs.

Named xenobots after the African clawed frog (Xenopus laevis) from which they take their stem cells, the machines are less than a millimeter (0.04 inches) wide -- small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups.

These are "entirely new life-forms," said the University of Vermont, which conducted the research with Tufts University.

Stem cells are unspecialized cells that have the ability to develop into different cell types. The researchers scraped living stem cells from frog embryos, and left them to incubate. Then, the cells were cut and reshaped into specific "body forms" designed by a supercomputer -- forms "never seen in nature," according to a news release from the University of Vermont.

The cells then began to work on their own -- skin cells bonded to form structure, while pulsing heart muscle cells allowed the robot to move on its own. Xenobots even have self-healing capabilities; when the scientists sliced into one robot, it healed by itself and kept moving.

"These are novel living machines," said Joshua Bongard, one of the lead researchers at the University of Vermont, in the news release. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

Xenobots don't look like traditional robots -- they have no shiny gears or robotic arms. Instead, they look more like a tiny blob of moving pink flesh. The researchers say this is deliberate -- this "biological machine" can achieve things typical robots of steel and plastic cannot.

The xenobots could potentially be used toward a host of tasks, according to the study, which was partially funded by the Defense Advanced Research Projects Agency, a federal agency that oversees the development of technology for military use.

"If we could make 3D biological form on demand, we could repair birth defects, reprogram tumors into normal tissue, regenerate after traumatic injury or degenerative disease, and defeat aging," said the researchers' website. This research could have "a massive impact on regenerative medicine (building body parts and inducing regeneration.)"

It may all sound like something from a dystopian sci-fi movie, but the researchers say there is no need for alarm.

The organisms come pre-loaded with their own food source of lipid and protein deposits, allowing them to live for a little over a week -- but they can't reproduce or evolve. However, their lifespan can increase to several weeks in nutrient-rich environments.

And although the supercomputer -- a powerful piece of artificial intelligence -- plays a big role in building these robots, it's "unlikely" that the AI could have evil intentions.

sick defence funding motherffuckers... you know damn well people will extend their lifespans to extremity and will think nothing of trying to convince them that all people are bad and need to be done away with... but hey, what could possibly go wrong when the world is full of kids and others more than happy to go into schools and churches and start blasting away

I really liked that part, lol.

This was the other disturbing part... the machines are less than a millimeter (0.04 inches) wide -- small enough to travel inside human bodies.











Somehow, biological nanobots sound way spookier.

I wonder if 5g rolling out has anything to do with the announcement of the creation of xenobots, cause that would be an interesting way to control them.

If they are truly living things, they will mutate in time to learn how to reproduce.

I wrote before that if I were to try and create sentient A.I. that I'd be programming biological beings and most likely using such beings that are suitable for other planets to pretty much terraform and colonize it. Water bears would be my first choice as they seem to be able to live about anywhere, though they don't seem to become mobile until they are exposed to moisture. The other way I'd likely go would be to take the living and replace its parts with cybernetics and try to reverse engineer the thinking process while continuing to cyborg the entity up until the last bit of biological based being is ultimately replaced.

The problem I see with stem cells and making the creatures self-healing, self-repairing, non-reproductive, and with a short limited lifespan is that being non-reproductive and having a limited lifespan both fall under problems to be repaired. They are also problems the Xenobots are specifically going to be programmed to go after and fix in human beings, so the chance of them self-repairing themselves would be fairly high even if they are programmed not to, as the coding to not do that would also be viewed as a problem that needs repaired. But if their programming doesn't allow them to self-repair in such a manner, it is still highly probably that they will simply start repairing each other, and when that occurs they most likely will be able to self-repair as though they had no restrictions placed into them as they will effectively have been reprogrammed and rewritten. If they are biological they will likely see one another as not being much if at all different than working upon any other biological being.

I am also reminded a lot of smart dust, but smart dust when I look it up isn't at all said to be biological. Xenobots are incredibly small, they can be the size of germs, and most likely can enter into the body through the skin without being noticed, nevertheless breathed in.

I don't see why these things can't be communicated and controlled like a computer wirelessly, which then runs into the problem that they can be used to enter one's body, hack all the knowledge one wants out of it, and input commands for a person to transfer their wealth, commit crime, vote certain ways, and so forth all through something as simple as 5g wireless technology. They could even rewrite a person's genetic code and pretty much upgrade or devolve the human race, through either commands sent to them or ones they just simply make up themselves.

if they can be used to heal,then they can be used to kill
