- Asterera.org published “The Rejuvenome Goals and Design,” outlining an open, large-scale mouse-aging project intended to generate high-resolution multi-omics longitudinal data for rejuvenation research.  
- A new arXiv preprint (2202.12887) proposes that mammalian “grid codes” act as biological error-correction codes, enabling fault-tolerant analog neural networks once per-neuron noise stays below a sharp threshold—suggesting a phase transition that links neuroscience and robust AI design.  
- BioRxiv papers report (i) micron-scale crisscross lattices built from combinatorial DNA-origami slats (10.1101/2022.01.06.475243v1) and (ii) real-time single-molecule protein sequencing on an integrated semiconductor device (10.1101/2022.01.04.475002v1), alongside a PLOS ONE theoretical analysis of weak-binding-spectra protein sequencing.  
- Discussion of force figures (9.8 kN to press a pin vs. 64 kN jet-engine thrust) clarified that the former refers to interference-fit insertion of precision steel parts using arbor or hydraulic presses, not ordinary pins.  
- Participants debated the credibility of a 45 mN satellite thruster concept, labeling it a possible propulsion scam and calling for rigorous critical evaluation.  
- When asked for an achievable FPGA project, “Halbach-array NMR” was suggested as a compact, low-field magnetic resonance platform suitable for hobbyist hardware experimentation.
