Engineers have long designed tough materials from tidy grids, because order is easy to predict. Nature often does the opposite: bone and spider silk owe part of their resilience to irregular, messy structure. A team led by The Chinese University of Hong Kong has now used physics-guided AI to design lightweight materials that borrow that lesson, and the printed results were tougher than the team had targeted. According to CUHK's press release, the study appeared in Physical Review X and was ...
