Scientists Resurrect 100 Million Safe Underwater Workers



Scientists have revived the germs found in the 100 million-year-old sediment, which gave us another idea of ​​what life was like in the past. As reported by Gizmodo, an international team of scientists led by geomicrobiologist Yuki Morono from the Japan Agency for Marine Science and Technology of the World resurrected these microbes that are currently from 101.5 million years ago.

Once the germs, which are a type of bacteria, were placed in laboratory conditions, they came back to life and began to eat and multiply, just as living things tend to do.

Even though these microbes are more than 100 million years old, they have been living in low-energy conditions that allow them to “maintain their metabolic potential,” according to a new research study published by Nature Communications.

“Again, this new study extends our perspective on the Earth’s habitable biosphere and the ability of microbes to live in suboptimal conditions,” Virginia Edgcomb, a geologist from the Oceanographic Institution of Woods Hole who was not involved in the new study, she said in an email. “It also extends our view of where viable microbial life contributes to carbon and other nutrient entry into the deep biosphere.”

There was a previous study of bacteria spores that were supposed to be from a 250 million-year-old salt crystal at the Permian Salado Formation in New Mexico, but not all experts agreed they really were since. One of the issues raised was that the samples were contaminated.

Using the DNA and RNA gene profile, these 101.5-year-old microbes were identified as aerobic or oxygen-loving bacteria and the “lack of permeability between the thick sea layers ”excluding contamination.

Jennifer Biddle, who is an associate professor in the School of Marine Science and Politics at the University of Delaware agreed with these findings and praised Morono.“In fact, I was given a precious sample of Martian material with which I could conclusively prove life on another planet, give it to Yuki Morono,” said Biddle, who was not involved in the new research.

Fortunately, Morono says the health risk of reviving old bacteria is very low as “subsurface sediment is considered a low health risk, as no host to infect, like a human being, it does not exist in this environment. ” Phew.
