So @trendless found & @RussSharek boosted link to report on hot new paper (Schulte & Huang) re Caltech development of new at-home test for COVID (& other paths).
It's 2.5x-100x more sensitive than current home antigen tests!

Pray commercial development happens ASAP.
More broadly, great quote here from Prof Barbara Wold: "The COVID-19 pandemic is a devilish teacher."
Yes. It has shown us much that is terrible to see. In our world. In ourselves.
