Producing the 3 to 5 grams of a biologic needed for IND-enabling studies costs millions of dollars using traditional CHO manufacturing. A single egg, meanwhile, contains 6 grams of protein, costs just 10 cents, and requires only chicken feed and water as inputs. Neion Bio is taking advantage of this incredible technology to turn chickens into drug factories. And they’ve already signed a commercial...

Twenty years ago, Dr. Derya Unutmaz predicted we would reverse aging by 2045. People thought he was crazy. Now, he thinks he was too conservative, and has moved the date up to 2040 because AGI arrived earlier than he expected. I sat down with Derya to ask if such bold predictions are too fatalistic. Is the future guaranteed? Shall we just sit back and wait for AI to save us? Derya disagreed. The g...

Health podcasts are probably shortening your life expectancy. Not just because of the health anxiety they create, but because that time could instead be spent writing a letter to your congressperson. Aging kills 85% of Americans, and the US spends $15-20 per person per year on cancer research but only $1 on aging biology. No amount of zone 2 and sauna are going to save you from that gap. I sat dow...

Reprogramming molecules are getting dosed into patients for the first time, with the goal of restoring function lost due to aging. I‘ve had over 30 recorded conversations about the longevity space and didn’t realize this is happening so soon! We sat down with Dr. Jamie Justice, the geroscientist running the $101M XPRIZE Healthspan competition, and she told us there are five teams pursuing reprogra...

AI is accelerating the pace of progress for benevolent scientists and nefarious actors alike. We discuss how DARPA is preparing to defend agriculture & civilians from novel biological threats, and why such defense requires training foundation models for biology. We also dive into why DARPA is betting on blood as the operating system for the body, lessons from GLP-1s for human enhancement, how...

Kris Borer is an entrepreneur, angel investor, and author of the new book Radical Life Extension .

We discuss the ethics of embryo selection and radical life extension. Jonathan has a Nietzschean view of humanity: within each of us we have the opportunit...

Twelve months ago, we didn’t have working antibody design models. Now we have models that can compress 18 month design timelines down to one month, and agents that can collapse weeks of work by expert protein designers to an afternoon. This is an exciting time. Simon Kohl is a former Google DeepMind research scientist on the Nobel Prize–winning AlphaFold 2 team, and is now the founder and CEO of L...

Elliot Hershberg is a partner at Amplify Partners and author of the popular blog Century of Biology. In this episode, we talk about GLP-1s as a breakthrough moment for biotech, why drug development is starting to behave like software, and how falling discovery costs could finally free biotech startups from selling themselves to pharma. We also talk about Elliot’s "massive markets, medium pric...

Today’s guest is Kexin Huang. Kexin recently raised $13.5M from Andreessen Horowitz and Menlo Ventures in partnership with Anthropic, to build Phylo - a research lab studying agentic biology. Phylo’s first product is Biomni, the world’s first open source IBE or Integrated Biology Environment for conducting agentic biology research. They intend to do for biology what the IDE did for software. Kexin...

Two young Harvard professors are coming for the supplements industry. Dr. Jonathan Gootenberg and Dr. Omar Abudayyeh run a joint lab at Harvard Medical School, have co-founded 4 biotechs, and raised over $300M to develop genetic medicines and diagnostics. But what surprised me most: they think like consumer tech founders, not academics. They start with what people actually want and work backwards...
