15,000-Year-Old Viruses Discovered In Tibetan Glacier Ice (osu.edu) 133

An anonymous reader quotes a report from Ohio State News: 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. The findings, published today in the journal Microbiome, could help scientists understand how viruses have evolved over centuries. For this study, the scientists also created a new, ultra-clean method of analyzing microbes and viruses in ice without contaminating it.

The researchers analyzed ice cores taken in 2015 from the Guliya ice cap in western China. The cores are collected at high altitudes -- the summit of Guliya, where this ice originated, is 22,000 feet above sea level. The ice cores contain layers of ice that accumulate year after year, trapping whatever was in the atmosphere around them at the time each layer froze. Those layers create a timeline of sorts, which scientists have used to understand more about climate change, microbes, viruses and gases throughout history. Researchers determined that the ice was nearly 15,000 years old using a combination of traditional and new, novel techniques to date this ice core. When they analyzed the ice, they found genetic codes for 33 viruses. Four of those viruses have already been identified by the scientific community. But at least 28 of them are novel. About half of them seemed to have survived at the time they were frozen not in spite of the ice, but because of it.

        Well, for God's sake, let's not let them have samples.

        For that matter, is there any real reason not to destroy them, we've seen the havoc that "novel" viruses can cause.

          The majority of viruses are bacteriophages, which infect bacteria and are harmless against multicellular animals. IIRC most of the rest infect plants, those which infect vertebrates are a slim minority and primate-affecting viruses are few and far between. That most of them are unknown isn't a surprise, most of the viruses in existence today are still unknown as well because there are a **LOT** of them and they're hard to study.

          It is more likely that these viruses have already been genetically accounted for as part of the past. A reverse version of this is something I've wondered about, in relation to say, the wooly mammoth they are trying to recreate from DNA. An animal that hasn't been around for 10K years or more is not going to have had exposure to all of the virus' that have evolved since it's time.

          The samples are from a Tibetan glacier. China has already taken over Tibet, they have all the samples they want.

        I mean, don't downplay the possibility, the research needed to turn the ancient viruses into modern Triple Zombie Brain Munchmunch variations has to take place SOMEWHERE, and at this stage of the game it could be China just as easily as any other country with advanced medical facilities! For all we know, labs across the world have already begun researching zombie virus, and I feel it's premature to call a winner yet...

    The article doesn't make it clear, so just to let everyone know - the odds of these things being infectious to humans are astronomically low. And, even if they were, after thawing their shelf life might be a couple of hours, or a few minutes if exposed to water or sunlight.

    • he odds of these things being infectious to humans are astronomically low. And, even if they were, after thawing their shelf life might be a couple of hours, or a few minutes if exposed to water or sunlight.

      But I have concern that their shelf life might become extended FAR too long, if they happen upon a human host.

      Lipid membranes are fairly fragile things , it doesn't take much to destroy them. Perhaps a better word would be "viable".

      Traditions can survive, and they aren't alive...

        I don't know about that, they reproduce and evolve over time, using (human) energy to propagate themselves, and eventually die. :0)

        • Do traditions die though? Look at the US, traditional Christian ethos. Likewise an attack on Obama was Muslim. Even in many ways pro democracy can be attached to a Christian ethos though the split seems more clear under Luther versus Catholicism but maybe that's what happens when a church splits to?follow the teachings primarily of one apostle.

          Shit missionaries in China are basically indistinguishable from pro democracy agent provocateurs...

            Traditions certainly do die, once upon a time the Arabian Peninsula was polyandrous with one wife having as many as seven husbands. (The shortage of women was maintained by selective infanticide, decided by the mother.)

            • Never heard this before. Very interesting. I guess my point is just like immortals, they can die but the methods of death are more limited, so death isn't guaranteed unless we are talking in terms of the heat death of the universe.

        • They don't reproduce, though.
          They don't just use human energy to propagate themselves, they use human everything.
          They're as alive as an mRNA vaccine, or any other RNA fragment floating between your cellular nucleus and mitochondria.
          Viruses are just a fragment of genetic code, that may or may not be covered in protective layers produced again, by our own cellular machinery. They have no metabolic function. They don't evolve, our imperfect cellular machinery evolves them.

            From a pragmatic point of view calling DNA "alive" is just stupid, because it destroys the meaning of that term. A stone would be "alive" by that definition. It is a time-honored tradition by idiots though to go to any and all lengths to try to claim they are right.

      • by gweihir ( 88907 )

        Traditions are not alive. The correct term is that a "tradition is being kept alive" and that does in no way mean the tradition itself is alive. It means there are people (which are alive) that keep the tradition.

        • An equally correct term is "the tradition survived".
          Survive doesn't have to be related to being alive. That's the point you are missing.

          Business survive, marriages survive. Along with religion, love, friendship, knowledge etc.

          Additionally not just intangible things can survive. Practically any physical object can survive. Since survive can just mean continue to exist. Old books, relics and artifacts are good examples. No life is necessary. If you want to pretend life is necessary for all those things.

      I understand what you're saying, but I could also say that a camera that falls from a great height, hits the ground, and still operates fine has "survived." So it can be used colloquially even if it is not the most technically correct usage of the word.
      • by gweihir ( 88907 )

        Well, depends. It is vertainly not exact use of language. But a camera has a rather complicated mechanism that you trigger and than execustes a sequence of things. In addition, a camera is valuable and provides a way to create emmotionally valuable artefacts. Hence many people go all "animism" on it and see it as something almost alive.

        A virus has nothing like that. If you are willing to make your argument for a stone, then that would be something else. Still not good language use though.

    Just allocate a CVE number for these, just like all the other malware we have! Did they consider if the viruses run on obsolete versions of Windows, on Penguin based OS, or on quantum platform? Just ensure these can't do privilege escalation to run on the enclosing virtual machine!
  • Genetic Evidence of 15,000-Year-Old Viruses Discovered In Tibetan Glacier Ice.

    It's still exceptionally cool to be able to study viruses from 15k years ago through preserved genetic material so they don't have to imply the viruses were discovered alive and intact. Although, this is maybe not as cool as the millions year old bacteria that were actually revived from dormancy.
