Microbes found in Meteors

Well, well, well..Fractured rocks of impact craters may be suitable hosts for deep microbial communities on Earth and potentially other terrestrial planets, yet direct evidence has remained elusive. Now, a team of researchers from the Linnaeus University and elsewhere has found evidence for ancient microbial life in rock samples from the Siljan impact crater in Sweden.Signs of Ancient Microbes Found within 381-Million-Year-Old Crater | Sci.News

Is it too much to ask to get a proposed topic promoted these days?
Is there anyone home?

Thread copied here from the Microbes found in Meteors thread in the Proposed New Topics forum.

Sorry I just now saw this. I hope I put the topic in an appropriate forum.

We examined the intensively fractured rock at significant depth in the crater and noted tiny crystals of calcium carbonate and sulfide in the fractures, said lead author Dr. Henrik Drake, a researcher in the Department of Biology and Environmental Science at the Linnaeus University.

​

When we analyzed the chemical composition within these crystals it became clear to us that they formed following microbial activity.

​

Specifically, the relative abundance of different isotopes of carbon and sulfur within these minerals tells us that microorganisms that produce and consume the greenhouse gas methane have been present, and also microbes that reduce sulfate into sulfide. These are isotopic fingerprints for ancient life.(...)
Detailed understanding of microbial colonization of impact craters has wide-ranging astro-biological implications, added co-author Dr. Magnus Ivarsson, from the Swedish Museum of Natural History.

Are they saying that the microbes came from elsewhere than earth? Im not clear on that part...

No - they’re talking about Earthly microbes moving into meteor impact sites. The thread title should be Microbes found in Meteor Craters.

Not quite. They've found evidence of ancient microbes in a crater made by a comet. There's a remaining question there. A big hint.

Ive got to really read the article deeper when I get the time. Im busy a lot.

I’ve skimmed the paper at ResearchGateThey are quite definitely talking about colonisation of the impact site by deep-living terrestrial microbes - about 300 million years after the impact.So, no. There is no suggestion that the microbes came from anywhere but deep in the Earth, and they even suggest that their methods can be used to avoid the mistake of thinking that the microbes arrived with the meteor.

On a somewhat related topic, I read that because of global warming the arctic permafrost is melting and potentially releasing lots of previously frozen virus,bacteria, and ancient goop that could infect living things again. Is this in any way true?

The permafrost is definitely melting. It will definitely contain. microbes. It could contain microbes capable of infecting humans. But I don’t think anyone died from infections caught from the frozen mammoths that have been dug out of there.I can’t rule out the possibility of there being something nasty out there, but it doesn’t seem a huge risk.

Compared to the risk from the methane that will be released the risks from microbes and viruses should be relatively minor.

I can't imagine that microbes from thawing arctic permafrost would pose any more risk to humans than microbes from the Congo or anywhere else.Many of the microbes in the arctic are what produces the methane.

It reminds me of a line from "The Jerk"; "enough of these old wines, bring me some NEW wines".Enough of those old viruses and microbes; bring me some NEW viruses and microbes.Any microbes or viruses from thawing permafrost will be viruses and microbes that it's likely humans have experienced before and so may have some immunity to any ill effects. But now them NEW viruses and microbes might be a whole different story.

Ahhh yes. Global warming. The Science based Leftist counterpart to the Right Wing CCoI Antichrist, False Prophets, Spiritual War, Armageddon scenario. And you guys have science on your side! I still predict that the supernatural (AKA The Unexplained) will become evident in the next few years. Of course you will pass it off as a delusion and fantasy just as many right wingnuts pass off global warming as a fantasy. The difference is that you have science on your side while all we have is subjective shared experience.This is why I drive down the middle of the road and try not to be too extreme either way.
