In 2020, scientists at Tufts created tiny novel living forms called xenobots from frog cells, capable of traversing a watery environment, healing their own injuries, and even gathering other cells to build xenobot siblings.

Now, researchers at Tufts and the Wyss Institute have taken the quest to reimagine life forms a step further, adding nerve cells and observing how they self-organize and alter xenobot behavior. The resulting neurobots take on new shapes and show unique behaviors…
