“Megabase-scale human genome rearrangement with programmable bridge recombinases”, et al 2025
“Induction of experimental cell division to generate cells with reduced chromosome ploidy”, et al 2025 (Pluripotent stem cells are useful, but hard to use, for the same reason blank books and new hard drives are.

Statistics/Meta-Science
“Adventures in State Space”, 2swap 2025 (visualizing a hard sliding-block puzzle’s game tree as a graph to understand why it’s hard, its symmetries, and the qualitative nature of its strategies; good intuition building for the idea of ‘state spaces’ in planning & reinforcement learning)
