From the Guardian: [UK Deputy Prime Minister Nick Clegg was] asked if there should be an inquiry into the role of British troops, [and] said: “I think anything that suggests that basic rules of war, conflict and engagement have been broken or that torture has been in any way condoned are extremely serious and need…
I don’t know what this means but “New discovery shows human cells can write RNA sequences into DNA” is worth looking into/Phys.org
https://phys.org/news/2021-06-discovery-human-cells-rna-sequences.html We already knew that under certain conditions (including infection with HIV, which contains a reverse transcriptase) cells could “write” RNA into DNA. But I didn’t think it happened that often. However, according to this paper, a DNA polymerase that is normally present in mammalian cells has this ability too. If so, it could really…

Yes, this is the one I was referencing in the post above this one (I am reading down the blog).
I didn't realize they took it down (though I surely realize why they did as it's horrible). I showed it to many physicians, nurses, and other public health professionals and after reading not a single one of them could tell me the difference between the two (because based on their reasoning herein, there isn't really a difference).
Actually, to be fair, there is a difference, but it's literally for about <1 second when tiny droplets are expelled into the air, evaporate, then become a germ floating in the air (which is CDC's definition of "airborne").
Also, here's that great MIT article on fluid dynamics showing that sneezes aerosolize and go 20 feet and get into ventilation systems if they're of a particular size.

A much bigger article needs to be written about all this…there's just so much misleading/confusing information going out.
