Covid 19 Origins

One of the early theories about Covid 19, was that it originated in a Wuhan market, where humans and animals were in close contact.

Recent research seems to have confirmed this. There are several mainstream media (newspaper) articles on this. I decided to try and find a more useful source. so this article on Web MD seems a good initial source.

• New studies indicate covid pandemic began wuhan market
  • The Huanan market was the epicenter of SARS-CoV-2 emergence
  • SARS-CoV-2 emergence very likely resulted from at least two zoonotic events
  • The Origins of SARS-CoV-2: A Critical Review

I think the above articles are also peer reviewed, so they are a more credible source, plus it is far better to read the original articles / papers than news paper reports which end up inaccurate, if the Journalist is not a specialist or just in some case lazy and sloppy.

The sense about science website has some good information and advise with regard to asking for evidence for research purposes. Along with this is an excellent introduction to the peer review process, so well worth reading.

It is good, that we are finally seeing the results of actual research in to this, and while it probably won't put conspiracy theories to bed, it may influence policies etc that are hopefully based on researched based evidence.

15,000-year-old viruses discovered in Tibetan glacier ice

Another interesting article from Science Daily [1] [2]

Summary:
    Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. 

So if life can exist in these extreme environments on Earth, could life also exist on other planets, moons in the solar system or Exoplanets and or Exomoons around other stars that have similar conditions.

“These are viruses that would have thrived in extreme environments,” said Matthew Sullivan, co-author of the study, professor of microbiology at Ohio State and director of Ohio State’s Center of Microbiome Science

So while the question of life out side of Earth is not the subject of this paper it does, for me at least, prompts the question could those conditions support life (even viruses) under any frozen surfaces.

I have created a discourse discussion for this [3]. The article is under Biology.

There is also a link here and on discourse to an explanation of 'habitable zone' means. [4] so this states “neither too hot nor too cold”
