- Discussion of World Bank “pandemic bonds” whose payout is triggered by a WHO pandemic declaration; concern that political pressure might delay the declaration to protect systemic financial stability.  
- justanotheruser reported that the first pandemic catastrophe bond is being defaulted on and noted the rapid shift of reinsurance risk from traditional insurers to capital markets (from 5 % to 20 % of capital at risk in a decade).  
- kanzure, maaku and yashgaroth are collaborating on an open-source coronavirus vaccine project (“coro-nope”) with the goal of publishing plasmid designs and minimal production data rather than creating a commercial product.  
- fenn posed a base-rate-fallacy quiz: if 1 % prevalence and a 99 % accurate test (1 % false-positive, 1 % false-negative) are assumed, only 50 % of positive results are true positives; maaku extended the calculation to 90 % test accuracy yielding 8.3 % true positives.  
- kanzure highlighted a questionable Bioviva fundraising email that quotes Warren Buffett, contains typos, and argues “Microsoft and Coca-Cola succeeded, therefore invest in us,” raising questions about SEC compliance.  
- fltrz sought high-specular-reflectance materials for a DIY UV-C (260–275 nm) disinfection chamber, comparing aluminum foil (~80 %), aluminized glass (~90 %), and ePTFE (94 %+) and noting that specular reflection simplifies fluence calculations by avoiding Monte-Carlo simulations.
