Over the past few days, the mainstream press has vigorously pushed back against a theory about the origins of the coronavirus that has now infected as many as 70,000+ people in Wuhan alone (depending on whom you believe). The theory is that China obtained the coronavirus via a Canadian research program, and started molding it into a bioweapon at the Institute of Virology in Wuhan. Politifact pointed the finger at Zero Hedge, in particular, though the story was widely shared across independent-leaning media.
The theory is that the virus, which was developed by infectious disease experts to function as a bio-weapon, originated in the Wuhan-based lab of Dr. Peng Zhou, China's preeminent researcher of bat immune systems, specifically in how their immune systems adapt to the presence of viruses like coronavirus and other destructive viruses. Somehow, the virus escaped from the lab, and the Hunan fish market where the virus supposedly originated is merely a ruse."
We suggest that you don't post this on Facebook or Twitter. They both have new policies and will probably delete your post. No sense getting in trouble. If you feel you have to share it with someone, email it.

UPDATE: This bioweapon paper has been withdrawn from the pre-print journal BioRxiv. This does not mean that it is wrong but the authors were severely criticized for breaking the bounds of propriety.
UPDATE2: The Bioweapon thesis is not panning out in newer papers. Here is a paper that discusses different receptors than the Indian Bioweapon paper.
