Scientists revive ‘zombie virus’ from nearly 50,000 years ago

WHAT YOU NEED TO KNOW:


  • Vast portions of permafrost have thawed due to global warming, releasing ancient microbes that can potentially be infectious.
  • Scientists revived some of these “zombie viruses” to assess their risk to public health.
  • One virus, named Pandoravirus yedoma, is believed to be 48,500 years old.

Global warming has caused vast portions of permafrost to melt, releasing ancient microbes that have been trapped for millennia.

Scientists revived some of these so-called “zombie viruses” from the Siberian permafrost to better study them. One virus, believed to be about 50,000 years old, has reanimated to a state capable of infecting other organisms.

Microbiologist Jean-Marie Alempic of the French National Centre for Scientific Research led the research team behind the study.

The team noted that permafrost covered “one-quarter of the Northern Hemisphere.” As this frozen ground thaws, previously frozen organic matter is released. These would then “decompose into carbon dioxide and methane, further enhancing the greenhouse effect.”

Rising temperatures have previously released huge numbers of bacteria into the environment, although these are less threatening given the current antibiotics. But a new virus, such as SARS-CoV-2, will cause more problems, considering the growing population in the Arctic.

The team warned that “the revival of an ancient unknown virus” could pose a significant threat to public health, thereby necessitating further study to assess “the risk of ancient viral particles remaining infectious and getting back into circulation.”

As the permafrost thaws, many more viruses will be released, aside from those that only target amoebas. Most of these will be completely unknown to science, but it’s also unknown how infectious they are once exposed to light, heat, and oxygen. Further study can look into this.

The researchers detailed 13 viruses in their new study. Nine of them are believed to be tens of thousands of years old, with one amoeba virus believed to be 48,500 years old. They stated that each one’s genome was distinct from all other known viruses.

The record-breaking find was extracted beneath a lake. Other microbes were found on mammoth wool and in a Siberian wolf’s intestines, which were all buried underneath the permafrost.

The researchers used live single-cell amoeba cultures in proving that the viruses could still become infectious.

The new virus was assigned the name Pandoravirus yedoma, given its size and the type of permafrost soil it was found in. The researchers previously discovered a similar virus, believed to be about 30,000 years old, in Siberia. That was also a pandoravirus, which is big enough to be seen using light microscopy.

Virologist Eric Delwart of the University of California, San Francisco, who wasn’t involved in the study, also believes that these finds are just the beginning.

Having plenty of experience with reanimating ancient plant viruses, Delwart told New Scientist, “If the authors are indeed isolating live viruses from ancient permafrost, it is likely that the even smaller, simpler mammalian viruses would also survive frozen for eons.”

The new study, which has yet to be peer-reviewed, was published on bioRxiv.

  1. Their you go weaponize ancient viruses, because you can damn sure bet, they don’t give two craps about the citizens .

  2. I am unsubscribing from the lying through their teeth Crystal News who uses the old Soviet method of controlling the opposition. As to the present lies of this article, there is no global warming, we are headed toward a period of intense period of cooling. There is more ice on the south pole than has been recorded in over one hundred years. Who pays you to write these outright lies? I am out of here for good. I cannot and will not tolerate paid liars.

  3. I call horse shit on the very premise! Some Zombie virus called pandora, like pandoras box, melting because of global warming? That is 100% fear porn to try to sucker the masses into buying their bullshit. Not to mention bringing it “back to life”. They’re just floating fear porn to see which line of shit hooks the most rubes.

  4. Maybe is government and scientists didn’t go making holes in the ground it wouldn’t escape. Maybe if they didn’t keep seeing how the can weaponize it there wouldn’t be a problem.
    Maybe if they just left nature alone overall the world wouldn’t be so messed up.
    Maybe people shouldn’t believe everything that they say.
    Maybe we should let it happen and start over again

  5. total BS . from the start, it`s based on ” global warming ” One time, we`re told the sun is in a cool down cycle. Then we`re told the ice is melting. Now it`s ” climate change ” . All of it is total, 100% B.S.. See Klause Schawb. Founder of the ” world economic forum” .
