On Star Trek: Discovery, the character Lieutenant Paul Stamets is an astromycologist" - a mushroom expert in outer space who is passionate about the power of fungi. Stamets is actually named after a real U.S. scientist who ... looks nothing like his blond-haired TV counterpart, but he's just as enamoured with fungi. Over 40 years, Stamets has pioneered methods for using mushrooms to do everything from clean up oil spills to save disappearing bees by boosting their immune systems. But he's just as excited about Star Trek's potential to inspire people to create some of the science they see presented in screen - even if it does seem a bit fantastic. So were flip phones when people first saw Spock's, he said. "What I love about Star Trek is that we can actually set the stage for science fact," said Stamets. In a 2008 TED Talk, Stamets explained how fungi can be used to "save the world" by cleaning polluted soil, replacing toxic insecticides and even treating viruses. "I'm just a messenger for the mycelium," he said, referring to the network of fungal filaments under the soil that form the largest organism on earth. Mycelium can be found in every forest, but the biggest one he knows of is a massive, 970-hectare mass - bigger than 1,600 football fields - in an Oregon forest. Stamets believes this network "communicates," not unlike a fungal internet. The filaments transfer nutrients and information, and even sabotage unwelcome plants by spreading toxins.
