Researchers from Newcastle University have crafted a new bio-based material called “mycocrete”. Using mycelium combined with additional natural materials, the team can grow a tightly wound substrate stronger than previous mycelium materials. The knitted design can create 3D shapes without seams or waste. “Our ambition is to transform the look, feel, and well-being of architectural … Read more
