- A new PNAS paper, “Magnetic control of heterogeneous ice nucleation with nanophase magnetite,” was shared, suggesting that magnetite nanoparticles can be used to trigger or inhibit ice formation, with potential applications in cryobiology and agriculture.  
- Rejuvenate Bio, a stealth Harvard startup co-founded by George Church, aims to reverse aging first in dogs and then in humans; it has already received a grant from the U.S. Special Operations Command to enhance military working dogs.  
- The eGauge energy-monitoring platform (https://www.egauge.net/) was highlighted as a tool for detailed, real-time tracking of household or lab power consumption.  
- Discussion of spaced-repetition software (e.g., Anki) for rapid skill acquisition: one participant created a 220-card Dolch-sight-words deck for teaching a child to read, then discontinued Anki once the child could read Dr. Seuss independently.  
- A critique of spaced repetition at scale noted that once card counts exceed ~200,000, daily review time becomes prohibitive unless one dedicates 8+ hours per day.
