Scientists Just Unveiled The World's First Wooden Electrical Transistor

You'll note powering functional electrical appliances isn't among them.
Researchers at Linköping University and the KTH Royal Institute of Technology in Sweden clearly never paid much attention to lists of things wood is bad at, so they went ahead and made the world's first wooden transistor.
