Swiss researchers have developed a biohybrid wood that glows in the dark, created through the interaction of the fungus Desarmillaria tabescens with non-living wood. The wood emits a soft green light at night and could be used to create sustainable light sources in building materials. The researchers are working to increase the brightness and duration of the bioluminescent wood. Possible applications include lighting in homes, streets, and forests, as well as incorporating bioluminescence into building materials for designer furniture or jewelry. The study was published in the scientific journal Advanced Science.
