Chances are that if you were heading into battle, you wouldn’t wish that you were covered in sponges. It turns out that the sea sponge, however, has a unique structure that allows it to be flexible while remaining relatively impervious to predators. Scientists have now simulated this structure, in a lab-created material that may someday find use in body armor.
