Tech in 24 hours on Instagram: "Scientists at Columbia University have created modular robots that can grow, heal, and adapt by "eating" parts from other machines—a process they call robot metabolism. These robots, built from simple "Truss Link" units with magnetic connectors, can connect, self-assemble into new shapes, and repair themselves by absorbing or replacing damaged modules without human help. This breakthrough brings robotics closer to mimicking biological adaptability, making future r
