Scientists at Rice University and the University of Houston have created a powerful new material by guiding bacteria to grow cellulose in aligned patterns, resulting in sheets with the strength of metals and the flexibility of plastic—without the pollution. Using a spinning bioreactor, they’ve turned Earth’s purest biopolymer into a high-performance alternative to plastic, capable of carrying heat, integrating advanced nanomaterials, and transforming packaging, electronics, and even energy storage.
