Scientists revive 100 million years old underwater life


Scientists have resurrected germs that were found in 100 million-year-old sediments, giving us another glimpse into life that was the same as in previous days. Marine-Earth Science and Technology revived these microbes that actually date back 101.5 million years.

Once germs, which are a type of bacteria, were put into laboratory conditions, they came back to life and began to eat and multiply, as do living things.

Even though these germs are over 100 million years old, they were living in a low-energy state, which allows them to “maintain their metabolic capacity,” according to a new research study published by Nature Communications.

Virginia Edgcomb, a geologist at the Woods Hole Oceanographic Institution, said, “Once again, this new study enhances our view of the biosphere living on Earth and the ability to adopt the state of microbes.” In an email “It also extends our approach to where viable microbial life contributes to the intensive biosphere of carbon and other nutrients.”

There was a previous study of bacterial spores believed to be from 250 million-year-old salt crystals in the Permian Salado Formation in New Mexico, but not all experts agreed that these were in fact back then. One of the issues brought up was that the samples were contaminated.

Using DNA and RNA gene profiling, these 101.5 million year old microbes were identified as anaerobic, or oxygen-loving, bacteria and a “lack of permeability between thick seafloor layers” that ruled out contamination.

Jennifer Biddle, who is an Associate Professor of the School of Marine Science and Policy at the University of Delaware, agreed with these findings and praised Morrow.“Had I been given a precious sample of Martian material with which I could attest to the evidence of life on another planet, I would give it to Yuki Morono,” said Biddle, who was not involved in the new research .

Fortunately, Morono states that the health risk of regenerating ancient bacteria is very low because “subsurface sediment is perceived as a low risk to health, as no infected host like humans exists in this environment. ” Oh, is that so.
