Traditional robots "degrade over time and can produce harmful ecological and health side effects", researchers said in the study, which was published Monday in the Proceedings of the National Academy of Sciences. These cells were then individually cut using tiny forceps, and an even tinier electrode, and joined under a microscope into a close approximation of the designs specified by the computer, the researchers said.
What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms? These organisms were able to explore their watery environment for days or weeks, powered only by embryonic energy stores.
Exams confirmed teams of them would transfer round in circles, pushing pellets right into a central location - spontaneously and collectively. The tiny blobs measure only 0.04 inches (1 millimeter) wide and are made of living tissue that biologists assembled into bodies designed by computer models, according to a new study.
While the frog-bots are still at a very early stage in development, it's possible that more complex versions could be used in the future for tasks like nano-surgery (performing jobs such as cleaning plaque from arteries or delivering drugs) and cleaning up micro-plastics.More news: Conor McGregor Thinks He'd Win a Floyd Mayweather Rematch
"We cut the living robot nearly in half, and its cells automatically zippered its body back up", he said. Xenobots even have self-healing capabilities; when the scientists sliced into one robot, it healed by itself and kept moving.
Although the current state of the xenobots is relatively harmless, there is the potential for future work to incorporate nervous system cells, or develop them into bioweapons.
The scientists are able to build the simulated model in real life by, essentially, taking fertilized frog embryos, separating their constituent cells, and then rebuilding those cells into the shape of the simulated model by cauterizing them together.
"They have never before existed on Earth", said Michael Levin, the director of the Allen Discovery Center at Tufts University in Medford, Massachusetts.

"It's 100% frog DNA - but these are not frogs".
In regards to how the frog cells' genomes are edited to make the new living machines, it seems that's unclear.
While the team acknowledges that there may be unintended consequences from developing such technology, such as the development of highly-targeted bioweapons, they argue that it is just another step toward cracking the "morphogenetic code", which they believe governs how all living organisms in the universe are organized.
Many people worry about the implications of rapid technological change and complex biological manipulations. Sure enough, they worked just as the simulations predicted they would. "We also need to understand the high-level rules", he says. "We'd have no idea". As organic machines, xenobots are extra environmentally pleasant and safer for human well being, the examine mentioned. "We want to understand that more deeply-and how we can direct and push it toward new forms".More news: Retired Lt. Gen. Michael Flynn Moves to Withdraw Guilty Plea
