• A 10 kg CubeSat with 7.5 kg of propellant could theoretically supply the ~2.5 km/s Δv needed to escape Earth from high-Earth orbit, but current CubeSats lack propulsion; participants shared the Railroad delta-v map and Wikipedia delta-v chart to visualize orbital-energy budgets.

• OpenWorm released an open-science paper modeling the complete C. elegans nervous system (http://journal.frontiersin.org/Journal/10.3389/fncom.2014.00137/full), while Microsoft Research showcased tools for stem-cell decision-making (http://research.microsoft.com/en-us/projects/rein/) and scenario-based biological modeling.

• The channel critiqued claims of human-brain uniqueness, debated the coherence of “Roko’s Basilisk” AI-punishment scenarios as a modern Pascal’s Wager, and explored whether ultra-slow general intelligence would still appear cognitive—linking extreme bradykinesia to post-encephalitic parkinsonism and Oliver Sacks’ “Awakenings.”

• Roman concrete’s volcanic-ash/lime mix cured in seawater achieves lower firing temperatures and superior longevity versus Portland cement, while a proposed optical/IR heterodyne technique could upconvert infrared images to visible wavelengths using nonlinear mixing and cheap silicon detectors.

• Antha, a new “programming language for biology,” was criticized for drag-and-drop syntax and lack of rigor compared with Transcriptic’s API; participants also dissected Ripple’s pivot away from distributed consensus and resurfaced Hal Finney’s 1990s essays on privacy protocols and biometric identity.

• Wei Dai’s LessWrong AMA was mined for Satoshi Nakamoto clues: Dai asserts only he and Nick Szabo combined the requisite monetary theory and crypto skills, and notes Satoshi reused Dai’s older Crypto++ SHA-256 code for early Bitcoin.

• NASA’s “Journey to Mars” briefing was dismissed as recycled political theater; participants advocate robot-centric exploration with cute telepresence avatars, citing Sony’s canceled QRIO humanoid and Google’s shuttered Glass as cautionary tales of corporate-driven futures.

• A PNAS paper showing low blood glucose increases aggression in married couples was circulated, reinforcing the channel’s interest in metabolism and cognition, while Russia’s GitHub block and libgen mirror availability sparked discussion on state censorship of open scientific code and literature.
