New Viruses Found In 15,000 Year Old Tibetan Glacier Ice

 

Viruses can survive in cold weather. Researchers and virologists discovered new viruses previously unknown in a Tibetan glacier ice . The samples were obtained from the Guliya Ice Cap. The discovery could explain the evolution of viruses. The ice is 15,000 years old, which provides a long history of biological information. Genetic codes were uncovered for 33 viruses. Only four were identified  and twenty eight were novel or unknown. Viruses appear to like cold environments according to the data collected. The origin of viruses might have been from plants and the soil not animals or humans. Scientists  used an ultra-clean method ( clean surface decontamination procedure)  to avoid contamination or being infected . The concern is what happens when global temperatures increase. Heat will cause glaciers to melt and could enable viruses to be exposed. A growing concern is over gain of function research and the hazards of manipulating viruses. Microbes have the ability to thrive in extreme environments. The ice samples provide details of the function of viruses over time. What is now confirmed is that climate can impact microbes as well.
