The world’s first ‘living robots’ can self-replicate, furthering hope for regenerative medicine

Last year, scientists created xenobots, tiny ‘machines’ engineered from frog stem cells. It turns out these organisms are capable of kinematic self-replication.
In January 2020, scientists created a new breed called the “Xenobots”—the world’s first-ever living robots, engineered from the stem cells of the Xenopus laevis species, or the African clawed frog. Xenobots functioned as tiny (less than a millimeter-wide)
