Russell spoke about BOINC ~4 years ago, Rosetta@Home is protein folding - with some jobs relevant to COVID. https://boinc.berkeley.edu/ https://en.wikipedia.org/wiki/Berkeley_Open_Infrastructure_for_Network_Comp… Rosetta@home https://en.wikipedia.org/wiki/Rosetta@home - Biology and Medicine http://boinc.bakerlab.org/rosetta/ There is equivocal evidence for Vitamin D decreasing risk of respiratory illnesses, with the suggestion that it may affect mostly people who are deficient in it. So getting some sun in Melbourne's gray days may be worth something for some of us. ... Exposure to light through windows is insufficient because glass almost completely blocks UVB light. Adequate amounts of vitamin D can be produced with moderate sun exposure to the face, arms and legs, averaging 5–30 minutes twice per week, or approximately 25% of the time for minimal sunburn.

Sunscreen <https://en.wikipedia.org/wiki/Sunscreen> absorbs or reflects ultraviolet light and prevents much of it from reaching the skin. https://www.ncbi.nlm.nih.gov/pubmed/28202713 BMJ. 2017 Feb 15;356:i6583. doi: 10.1136/bmj.i6583.
