Researchers from the University of Reading demonstrated that a simple hydrogel can learn to play the simple 1970s computer game " Pong " The emergent learning behavior is thought to arise from movement of charged particles in response to electrical stimulation, creating a form of 'memory' within the material itself.

The research team believes their findings could have far-reaching implications for fields ranging from soft robotics to environmental and robotics.
