Engineered living materials with bacterial spores show promise for self-healing and sustainability

Bacterial spores—the hardy survival structures formed by certain bacterial species—are proving to be a game changer in the field of engineered living materials (ELMs). By embedding Bacillus spores within ELMs, Jeong-Joo Oh, Franka van der Linden, Marie-Eve Aubin-Tam and their fellow researchers have created living materials that not only endure harsh environments but can also be programmed to perform specific tasks.
