Ben Lamm on De-Extinction, Gene Editing, and the Future of Life

The Power of Gene Editing

• 🧬 CRISPR technology has advanced from single nucleotide edits to synthesizing large blocks of DNA, enabling more complex genetic engineering.
• 🧩 Multiplex editing combines various tools (knockouts, knock-ins, synthesis) to make numerous edits simultaneously, pushing the boundaries of genome engineering.
• 🔬 Colossal Biosciences has successfully created a woolly mouse with eight edits across seven genes, conferring traits like altered hair texture and density, demonstrating the potential for de-extinction and trait engineering.

Engineering Life and Conservation

• 🧬 Somatic cell nuclear transfer (SCNT) is a key technique, involving transferring the nucleus of a somatic cell into an egg cell to create embryos.
• 🥚 The development of a universal egg is a major goal to overcome challenges in SCNT, especially for endangered species, by creating a compatible host cell.
• 🤰 Artificial wombs are being developed as a full end-to-end system to grow embryos ex utero, with potential applications in conservation and species revival.
• 🦏 Colossal Biosciences is involved in conservation efforts, including the Northern White Rhino project, aiming to use their technologies to prevent species extinction at scale.

Ethical Considerations and Human Applications

• 🤔 The conversation delves into the ethics of de-extinction and gene editing, questioning the line between scientific advancement and playing God.
• ⚖️ While Colossal focuses on animals and conservation, the technologies developed have potential applications in human healthcare, including gene therapy and artificial wombs.
• 👶 IVF and embryo selection are discussed, including the use of genetic screening for predispositions to diseases and the ethical debates surrounding eugenics and gene selection.
• 🌍 The role of AI in biology is highlighted, with potential to accelerate research, analyze vast datasets, and predict genetic outcomes, moving from scientific discovery to engineering.

Future Frontiers and Challenges

• 🚀 Longevity escape velocity is discussed as a future possibility, driven by advancements in therapeutics, AI, and understanding biological processes.
• 🦠 A microbe capable of breaking down plastics into biomass is presented as a significant breakthrough for environmental remediation.
• 🌳 Future aspirations include engineering plants to build dwellings and creating underwater cities with resilient coral and closed-loop systems.
• 💡 Inspiring the next generation of scientists through ambitious projects like de-extinction is seen as a crucial outcome, akin to the impact of the Apollo program.
