Science News from research organizations How everyday foam reveals the secret logic of artificial intelligence Foams don’t just sit still—they behave like a learning AI, constantly reorganizing beneath the surface. Date: January 15, 2026 Source: University of Pennsylvania School of Engineering and Applied Science Summary: Foams were once thought to behave like glass, with bubbles frozen in place at the microscopic level. But new simulations reveal that foam bubbles are always shifting, even while the foam keeps its overall shape.
