The technology behind it isn’t new, but The Thought Emporium is a Youtuber who:
1: DIY-d a genetically modified virus to cure his own lactose intolerance (successfully)
2: Is currently working on a biological computer that runs on animal neurons.
3: Has livestreams where the viewers submit ideas (like making tomatoes spicy) and he designs DNA to accomplish it.
Also he helped shut down a scam health product that contained radioactive material which isn’t particularly futuristic (actually it reminds me of the “radiation is good for you” craze in the early 20th century) but I wanted to mention it anyways.
