• A “ball-bearing vacuum pump” concept was proposed: a closed-loop slingatron-style track in which sapphire micro-balls alternately compress and expand gas to create a molecular-flow pump, potentially replacing expensive magnetic-bearing turbomolecular pumps; participants suggested piezo or cellphone-vibration actuation, steel manifolds, and Molflow Monte-Carlo or DSMC simulations to validate the design.

• Liver-regeneration data from a 1979 rat study—hepatocytes injected into the spleen grew to 40 % of organ mass—was cited alongside a blog post arguing that thymus regrowth could be a longevity intervention.

• DNA-origami tooling gaps were highlighted: cadnano JSON files cannot yet be losslessly imported into NanoEngineer-1’s .mmp format; an undocumented legacy encoder and a stalled cadnano plugin API were identified as the missing links.

• Two neuroscience papers were shared: one correlating microstructural differences in the ventral language pathway with language-learning under working-memory constraints, and another showing that electrical stimulation of Broca’s area improves implicit artificial-grammar learning.

• A blockchain-for-science proposal was sketched in which miners perform Bitcoin-style PoW but 50 % of new coins retroactively reward mathematicians who submit formally verified proofs or counter-examples, with public bets weighting the payouts.

• A related scheme for monetizing cryptographic zero-days was debated: anonymous posters could salt-prove breaks on-chain and claim bounties after confirmation; concerns about miner front-running were countered with public-key inclusion and built-in time delays.

• Bitcoin post-2013 innovations—sidechains (Elements Project), Lightning Network, and ~100-confirmation testnet transfers—were discussed, along with the argument that deep reorgs are normal and that mining rewards are non-stealable due to proof-of-work coupling to the coinbase transaction.

• A detailed economic attack on MaidSafe’s storage-reward mechanism was outlined: colluding nodes can request the same encrypted chunks, slash real storage costs, and reinvest excess earnings to dominate the network; the flaw had been publicly disclosed earlier.
