- A circulated blog post titled “The GWAS hoax—or was it a hoax?” challenges the “omnigenic” model that claims nearly every gene influences complex traits, sparking debate over whether personal identity can be reduced to one’s entire genome.  
- An MIT Lincoln Laboratory paper on “Brazing molybdenum and graphite with a titanium-based powder filler metal” was shared as a practical guide for high-temperature material joining useful in vacuum or space hardware.  
- Participants re-examined cost estimates for climate-engineering interventions, noting that many proposals cluster around the “$1 billion” figure, and linked National Academies and Copenhagen Consensus Center reports on aerosol geoengineering and radiative-forcing models.  
- Discussion highlighted the political bottleneck to low-cost geoengineering: technical solutions such as ship-borne ocean bubblers or reversible star-shades could be deployed for ~$100–400 M, but unilateral action is blocked by global-governance concerns and reputational risk.  
- Isaac Arthur’s YouTube channel—offering 91 videos on space colonization, Kardashev civilizations, the Fermi paradox, and transhuman futures—was recommended as a comprehensive futurist resource.
