What’s Behind The Blockchain-Based Art Boom? From multi-million dollar art sales to short NBA video clips, non-fungible tokens have taken off as a way to license media in the digital realm. The blockchain-based tokens, which function as a certificate of ownership for purchasers, produce a dramatic amount of carbon emissions and aren’t actually new—but in the first quarter of 2021, buyers spent $2 billion dollars purchasing NFTs on online marketplaces. Writers, musicians, and artists are all now experimenting with them, and big brands are also jumping on the bandwagon. Ira talks to Decrypt Media editor-in-chief Dan Roberts, and LA-based artist Vakseen about the appeal, and how NFTs are bringing new audiences both to the blockchain economy, and artists themselves. How Novel Is Neuralink? Last month, the company Neuralink, co-founded by Elon Musk, released a video update of their technology. The company makes brain-computer interfaces, or BCIs—implants in the brain that detect signals and send them to a computer. In the video, a macaque named Pager sits in front of a screen, while a narrator explains Pager had two Neuralinks implanted in both sides of his brain six weeks before. Pager is playing Pong. Not with a joystick or controller, but with his brain, according to the narrator. As with any Elon Musk venture, this Neuralink video got a lot of buzz. But brain-computer interfaces themselves are not a new concept. Where does this fit into the realm of neurotechnology research? Joining Ira to talk about this Neuralink update is Dr. Paul Nuyujukian, director of Stanford University’s Brain Interfacing Laboratory in Palo Alto, California. Ira also turns to Nathan Copeland, a neurotechnology consultant and brain-computer interface participant in Pittsburgh, Pennsylvania. Six years ago, Copeland had four BCI devices implanted, and is one of just a handful of people to have BCI implants in his brain. Decolonizing And Diversifying The Future Of Food The Science Friday Book Club has been talking about food all spring while reading Lost Feast: Culinary Extinction and the Future of Food. We discussed the impacts of meat consumption, the extinction of beloved birds and plants, and the declining variety of fruit and vegetable varieties available in stores—and even about the flow of pollinator-produced crops in global food systems.  Producer Christie Taylor shares highlights from our off-radio Zoom event series, which asked, “What is the future of food, and who can help influence it for the better?” At this April 20th panel, Lost Feast author and food geographer Lenore Newman joined farmer and former chef Mimi Edelman to talk about the future of food and flavor—from preserving heirloom seeds to the stories behind beloved flavors, and how policy changes and individual actions might contribute to a sustainable future. At this May 4th panel, food researchers Katie Kamelamela, Noa Kekuewa Lincoln, and Melissa K. Nelson talked about their work researching and restoring Indigenous foods to Hawaii and the mainland United States. They explained how these foods were disrupted by colonization, and how food relationships fit into a future vision of sustainable food worldwide.
