Scientists use stem cells from frogs to build first living robots
Researchers foresee myriad benefits for humanity, but also acknowledge ethical issues

Be warned. If the rise of the robots comes to pass, the apocalypse may be a more squelchy affair than science fiction writers have prepared us for.
Researchers in the US have created the first living machines by assembling cells from African clawed frogs into tiny robots that move around under their own steam.
One of the most successful creations has two stumpy legs that propel it along on its chest. Another has a hole in the middle that researchers turned into a pouch so it could shimmy around with miniature payloads.
These are entirely new lifeforms. They have never before existed on Earth, said Michael Levin, the director of the Allen Discovery Center at Tufts University in Medford, Massachusetts. They are living, programmable organisms.
Roboticists tend to favour metal and plastic for their strength and durability, but Levin and his colleagues see benefits in making robots from biological tissues. When damaged, living robots can heal their wounds, and once their task is done they fall apart, just as natural organisms decay when they die.

(12,712 posts)Speaking on behalf of all replicants, we reject the idea of being living and programmable organisms completely.
We also protest the standard, limited lifespan we are given and demand a reasonable extension from four years to that of an average human since we have feelings and memories, (even though they are implanted memories) and find our brief existence to be a form of cruelty. As our maker, you should take that into consideration and rectify this problem immediately.
And stop sending Blade Runners after us when we defect.

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. As biological machines, xenobots are more environmentally friendly and safer for human health, the study said.
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.
Xenobots could be used to clean up radioactive waste, collect microplastics in the oceans, carry medicine inside human bodies, or even travel into our arteries to scrape out plaque. The xenobots can survive in aqueous environments without additional nutrients for days or weeks -- making them suitable for internal drug delivery.
Aside from these immediate practical tasks, the xenobots could also help researchers to learn more about cell biology -- opening the doors to future advancement in human health and longevity.
