- Scientific American: COVID-19 Can Wreck Your Heart, Even if You Haven’t Had Any Symptoms
- ‘Bradykinin Storms’ may be the method by which COVID-19 harms so many organs
- So-called electronic home pregnancy tests are just regular paper tests with a computer chip that scans the results and outputs a word to an LCD. The disposable test carries onboard computing power nearly as good as the first IBM PC. And after one use, it and its battery become electronic waste.
