CO2, water, microplastic: fashion is one of the world's most polluting industries. In a bid to limit pollution, biotechnology researchers from the universities of Newcastle and Northumbria in the UK have just developed a textile material based on mycelium - the vegetative part of fungi - capable of self-repair. The results, published in Advanced Functional Materials, suggest that mycelium materials can survive in dry and oligotrophic environments, and self-healing is possible with minimal intervention after a two-day recovery period. This discovery could soon revolutionize the textile industry.
