- Free online longevity-science conference “Longevity 2020” announced for the following week at www.longevity2020.com.  
- University of Louisville researchers (Paula Bates, John Trent, Don Miller, Kenneth Palmer) repurposed an anti-cancer DNA aptamer that binds nucleolin to block SARS-CoV-2 replication; FDA fast-track application underway.  
- Discussion of open Raman-spectroscopy databases: participants lamented restrictive licensing of existing collections (e.g., SDBS) and desire a freely downloadable, comprehensive library for DIY spectrometers.  
- Cost-reduction ideas for Raman setups: replacing expensive notch filters with high-/low-pass filters (~$12–$16 on eBay) or destructive-interference schemes; RamanPi cited as an open-hardware example needing refinement.  
- Query posed to a Metrohm Raman specialist: availability of open spectral libraries and notch-filter-free instrument designs.  
- “Pointproofs: Aggregating proofs for multiple vector commitments” (eprint 2020/419) shared as a new cryptographic primitive.  
- Brainstorm on ultra-low-cost amino-acid synthesis: electrically driven routes and a recalled ESA-linked startup that feeds microbes H₂ + CO₂ to produce protein.  
- Speculative imaging concept: passive super-resolution microscopy by detecting uncorrelated air-molecule collisions with a surface instead of using active neutral-molecule beams.  
- Practical cryopreservation tangent: why liquid-nitrogen household food storage is not widespread despite eliminating frequent grocery trips.
