Xenopus laevis embryos of the African clawed frog, a species that had been used for decades to detect pregnancy in the United States, (only to be later released into U.S. waters after they were no longer needed in labs), has the capability to regenerate fully functioning eyes, according to researchers with the University of Nevada at Las Vegas.
