- UCSF reported that the small-molecule ISR inhibitor ISRIB rapidly reverses age-related cognitive decline in mice, restoring spatial memory performance in days; participants noted the published maze data lack young-mouse baselines, making the magnitude of the effect hard to gauge.  
- A Nature Biotechnology paper demonstrated a tissue-engineered, cell-seeded polymer uterus that enabled full-term live births in rabbits, marking a significant advance in regenerative reproductive medicine.  
- Discussion of DNA strand inheritance in asymmetric stem-cell divisions (A → A + B) raised the hypothesis that the “immortal” strand mechanism may protect long-lived stem cells from replication-induced mutations, with suggestions for radiolabeling experiments to test the idea.  
- A cybersecurity scenario was floated in which attackers use man-in-the-browser techniques to alter DNA synthesis orders, prompting the half-serious question of whether the same vector could be exploited to clandestinely produce nootropics instead of toxins.  
- Practical emergency-medical identification was debated: blood-group tattoos (historically used by the Waffen-SS) were weighed against modern phone-based medical records, with consensus that routine rapid blood-typing and additional antigen matching make tattoos largely obsolete outside extreme isolation scenarios.
