- nmz787 released an open-source vacuum control system that integrates vacuum and thermal sensor feedback with relay-switched pneumatic valves for reagent introduction; the Python code is available at https://github.com/nmz787/vacuum/blob/master/main_system_control.py.  
- Participants discussed a new serological assay for detecting SARS-CoV-2 seroconversion posted on medRxiv, as well as the Nurx $181 at-home COVID-19 PCR test kit that ships a self-collection swab.  
- The Wuhan “10-day hospital” built from prefabricated modules was highlighted as a model for rapid, low-labor construction; debate followed on whether short service life and regulatory hurdles make such methods uneconomical in the West.  
- A U.S. Army Rydberg-atom quantum sensor able to detect electric fields from 0 to 10¹² Hz was shared (https://phys.org/news/2020-03-scientists-quantum-sensor-entire-radio.amp), with claims of calibration certainty derived from quantum mechanics.  
- Folding@home was reported to have reached 470 petaflops of aggregate compute, prompting calls for Microsoft and Sony to deploy clients on Xbox and PlayStation consoles to further boost COVID-19 drug-discovery workloads.  
- Evidence was reviewed that hydroxychloroquine, quercetin, EGCG (green-tea extract), chloroquine, and macrolide antibiotics (e.g., azithromycin) act as zinc ionophores, potentially enhancing intracellular zinc levels to inhibit viral replication; a MedCram video (http://youtu.be/vE4_LsftNKM) was cited.  
- Concerns were raised that quercetin might elevate cytokine levels and exacerbate “cytokine storm,” while availability of chloroquine for personal stockpiling was questioned on ethical grounds.  
- A conspiracy claim that SARS-CoV-2 contains “CRISPR artifacts” was analyzed; participants concluded that any FRT or scar sequences would have been readily detected in published genomes and publicly flagged by reputable scientists.  
- fltrz requested educational resources on the immune system’s antibody-generation mechanism; jrayhawk provided LibGen immunology topic links (https://libgen.is/search.php?req=topicid156) pointing to foundational texts by Abbas, Janeway, and Paul.
