It may seem like magic, but it is possible to manufacture "food from thin air"—at least in appearance. If you want to discover how, and which companies are doing it today, listen to the fabulous podcast, Gastropod, hosted by Nicky Twilley and Cynthia Graber. After I wrote about century-old attempts to make food from air by Marcellin Berthelot and his son Daniel Berthelot in Popular Science, I had an awesome conversation with Nicky and Cynthia who dive deeper into the science in their episode, "Yes, You Really Can Make Food From Thin Air—And We Tried It." Don't miss it!

Many thanks to Cynthia Graber and Nicky Twilley
