World's First Living and Self-Healing Robot Made from Frogs' Stem Cells

Scientists have created the world's first living and self-healing robot from frog stem cells. It has used stem cells of African clawed frogs. It is less than a millimeter (0.004 in) in size. Because of this it can easily move in the human body.

According to scientists, this robot can easily walk and swim in the human body. In addition, one can remain alive without food for several weeks and can also work together in a group. Vermont University reported that it is a completely new form of life. This research has been done by the University of Vermont in collaboration with Tufts University.

Stem cells are specialized cells, which have the potential to grow into different types of cells. The researchers extracted living stem cells from the frog's embryo and released them onto the egg. Then, the cells were split and transformed into specific "body forms" designed by supercomputers. According to the researchers, this was never seen in nature. After this, Sales started working on its own. The skin cells formed the structure, while the pulsation of the heart muscle cells allowed the robot to move on its own. Xenobots also have the ability to self-heal; When the scientists sliced ​​the robot, it recovered automatically and kept going.

Joshua Bongard, a researcher, said that this is a unique machine. According to them, 'It is neither a traditional robot nor any known species of animal. It is a new kind of living machine. Xenobots does not look like a conventional robot. It has neither gear or arms. Instead they look more like a small piece of pink flesh. According to the researchers, it is a biological machine.

Exnobots can be used to collect radioactive wastes, microplastics, in groups. Drugs can be carried in the human body. Even the arteries can move easily. Exnobots can survive for days or weeks without additional nutrients in aquatic environments. These can be made suitable for internal drug delivery. In addition to these immediate work, xenobots can also help researchers learn more about cell biology. In addition, human health and longevity may be important in the future.
