At the same time, however, these xenobots are remarkably lifelike in that they're comprised entirely of biological materials, feed off energy supplied by their cells, move with intent and even fix their injuries. Xenobiotics are not traditional robots and they don't even belong to any animal species.
In a test to see what would happen when a xenobot was cut nearly entirely in half, the bot automatically stitched itself together and was able to get back on track. They hope that this new type of organism - contracting cells and passive cells stuck together - and its eerily advanced behavior can help scientists unlock the mysteries of cellular communication.
The freakish creatures were created using an "evolutionary algorithm" a supercomputer that generates 3D configurations of 500 to 1,000 skin and heart cells before being assembled and tested by biologists at Tufts University. The xenobots are made from frog stem cells and are less than a millimeter (0.04 inch) wide, and travel in blood vessels. The researchers said that the computer, after 100 independent runs of the algorithm, selected the most promising designs for testing. Next, the team at Tufts worked with microsurgeon to transfer the silicon designs into life. The bots were named after the species of African frogs, Xenopus laevis, whose embryonic cells, or stem cells the research team gathered for the project. "What we are very interested in is how cells work together to create specific functional structures".
Many of our gadgets and other technologies are made of steel, plastic, silicon. The Xenobots has the capability to heal on its own and is safer for the health of human beings. "The downside of living tissue is that it's weak and it degrades", say Bongard.
It won't be long before we send fleets of small nanobots to our bodies to deliver drugs and solve some of the annoying problems that could otherwise cause irreparable damage and even death. "We sliced the robot nearly in half and it stitches itself back up and keeps going", said Bongard. That is one thing you'll be able to't do with typical machines'. This is organic computation, which the authors explain as the information is shared and cooperated between cells. The researchers also experimented with creating a pouch inside the new life-forms, allowing them to carry a payload around.

Australia record easy 10-wicket win over India in first ODI
The duo chased down the below-par 255 run total in just 37.4 overs easily as they remained glued to the middle till the very end. It marked just the fifth time Australia's two openers have scored centuries in the same innings of a one-day worldwide .
A bottle of champagne comes between the women
Hannah Ann Sluss obtained over the crowd and judges along with her educated modeling abilities, profitable the total say. Brown admitted she wasn't obvious if she made the magnificent preference when sending Weber home on The Bachelorette .
"[Living cells] run on DNA-specified hardware", he adds, "and these processes are reconfigurable, enabling novel living forms".
"We can imagine many useful applications of these living robots that other machines can't do", says co-leader Michael Levin who directs the Centre for Regenerative and Developmental Biology at Tufts, "like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, travelling in arteries to scrape out plaque".
What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms?
"That distress isn't unreasonable", Levin stated. "If you wanted an anthill with two chimneys instead of one, how do you modify the ants?"
"What's important to me is that this is public, so we can have a discussion as a society and policymakers can decide what is the best course of action", says Sam Kriegman, PhD student at the UofV.
