- New Scientist reports that human brain organoids can now be cryopreserved and revived without damage, potentially improving storage and transport of neural tissue for research and therapy.  
- Archaeological findings of human brains preserved for thousands of years—lacking skin, muscle, or gut—sparked discussion of unknown preservation mechanisms involving high metal content and saponification (fat-to-soap conversion).  
- Examples of exceptional soft-tissue preservation were shared, including 3,300-year-old moa claws and medieval “bog bodies,” illustrating how specific environmental chemistry can arrest decay.  
- A debate on the nature of intelligence questioned whether higher-IQ individuals can design better IQ tests, with arguments that any new test is still anchored to prior metrics and that “intelligence” must be defined relative to the environment and tasks.  
- Participants critiqued the reductive view that “IQ only measures IQ-test performance,” citing longitudinal studies linking scores to life outcomes and noting objective components such as processing speed.  
- The limits of single-score metrics were highlighted: uneven cognitive profiles (e.g., high reasoning but average processing speed) can be masked by averaging, and conditions like ADHD or autism can distort sub-scores.  
- Discussion turned to the possibility of biological enhancement: reverse-engineering the physical basis of human memory was proposed as a route to “intelligence maximalization” and overcoming fixed cognitive ceilings.  
- A provocative comparison claimed that many low-IQ humans are functionally indistinguishable from higher animals, while others countered that even low-scoring individuals display unique capacities like abstract language.
