- Keinice Bio (run by Alcor’s Tanya Jones) is developing ultra-cold helium-gas perfusion (“persufflation”) for cryopreservation, claiming it vitrifies tissue fast enough to avoid both ice-crystal damage and the toxicity of conventional liquid cryoprotectants; the method is said to work by forcing the chilled gas through the vascular system.  
- Channel participants debated whether helium persufflation is genuinely novel, noting that the concept dates back to at least 2013 and that Mike Darwin had previously advocated it; practical obstacles for large organs and whole bodies were highlighted.  
- Colossal Biosciences announced a $150 million raise for de-extinction of the dodo (and previously the woolly mammoth), prompting skepticism about the business model—whether revenue will come from zoos, entertainment, or future conservation contracts—and concern that the promise of “bringing species back” could reduce present-day conservation incentives.  
- Discussion pivoted to unconventional livestock: farming manatees, dugongs, and even rhinoceroses for meat was proposed, with participants weighing growth rates, safety, and the precedent of 50 billion chickens produced annually.  
- Industrial-scale algae (spirulina, chlorella, duckweed) was revisited as a high-protein, low-water-input food or feedstock; harvesting via flocculation and the use of closed solar bioreactors with CO₂-enriched aquatic CAM or C4 plants were suggested as ways to overcome diffusion limits and water loss.
