Microbial Time Travelers: A Shocking Revival from the Depths

In a groundbreaking discovery, scientists have revived ancient microbes that have been lying dormant for over 100 million years under the seafloor. These incredible microorganisms demonstrate remarkable survival skills, thriving in rock sediments with almost no nutrients.

Deep-Sea Discovery: The Research Expedition That Changed Everything

Researchers from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and the University of Rhode Island conducted the study, releasing their findings in *Nature Communications*. They retrieved sediment samples from a staggering depth of 75 meters (246 feet) beneath the seafloor in the South Pacific Ocean, almost 5,700 meters (18,700 feet) below sea level.

The Miracle of Revival: From Dormant to Dynamic

Once in the lab, these ancient microbes were coaxed back to life using carefully controlled techniques. By providing isotope-labeled carbon and nitrogen-rich nutrients, the team observed that within a mere 10 weeks, these microbes
