New study reveals regeneration of amputated body parts is not always an ancient trait and scientists might need to rethink the way they compare animals with regenerative abilities. An international group of researchers including biologists from the University of Maryland found that at least four species of marine ribbon worms independently recently evolved the ability…

Self-navigation…
Human eyes are insensitive to polarized light and ultraviolet radiation, but that is not the case for ants, who use it to locate themselves in space. AntBot, a robot designed by CNRS and Aix-Marseille University (AMU) researchers at ISM, copies the desert ants' exceptional navigation capacities to navigate without the use of GPS. (1) Navigating…
