Imagine this: an ancient virus<\/strong> awakens after thousands of years and triggers a global pandemic. Sounds like a Hollywood movie, doesn’t it? But what if we told you that this is more than fiction; it’s a real possibility that we could be exposed to due to climate change<\/strong>?<\/p>\n\n\n

A new study<\/a> published in the journal PLOS Computational Biology<\/strong> raises alarms about the ecological and health risks of “time-traveling” pathogens that could be released due to the thawing of permafrost<\/strong>, a layer of frozen soil found in polar and mountainous regions of the planet.<\/p>\n\n\n\n

The uniqueness of this frozen layer is that it perfectly preserves the organic remains of animals and plants<\/a> that inhabited the Earth long ago, as well as microorganisms that have been inactive for thousands or even millions of years<\/strong>. However, rising temperatures are causing the permafrost to melt and release these dormant microorganisms<\/strong>.<\/p>\n\n\n\n

In order to assess the threats we could potentially face, an international team of researchers conducted a computer simulation where they introduced virtual viruses from the past<\/strong> into present-day bacterial communities.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

The results are quite surprising: 3% of the ancient viruses managed to survive<\/strong> and evolve in the modern environment, and some of them even caused significant changes in bacterial diversity<\/strong>.<\/p>\n\n\n\n

Specifically, 1% of the ancient viruses had unpredictable effects: some increased bacterial diversity by up to 12%<\/strong>, while others decreased it by up to 32%. These invading viruses not only adapted to the current conditions but also disrupted the ecological balance<\/strong>.<\/p>\n\n\n

While this is a simulation, the authors of the study warn that these scenarios could occur in reality with actual pathogens<\/strong>. The researchers acknowledge that it’s difficult to estimate the risk of an ancient pathogen causing a serious or contagious disease in humans, but they do not rule it out<\/strong>.<\/p>\n\n\n\n
