A type of damage in soft materials and tissue called cavitation is one of the least-studied phenomena in physics, materials science and biology, but evidence suggesting that cavitation occurs in the brain during sudden impact leading to traumatic brain injury has accelerated interest, says materials scientist Alfred Crosby at UMass Amherst. He is the senior author of a “Perspectives” paper this week in PNAS intended to spark fresh discussion and collaboration from new disciplines.
