Every civilization leaves something behind. Pottery, bones, tools – but this time, the story came from within. Hidden inside a man who lived a thousand years ago in Zimapán, Mexico, scientists found traces of ancient gut bacteria. Evidence of these gut microbes survived long after his world vanished. They carry clues about how people once lived, ate, and stayed healthy …

Microbes that have been suspended in permafrost for up to 40,000 years could “reawaken” and start churning out greenhouse gases if Arctic summers grow much longer, new research suggests. Under future climate conditions, microbes that have been dormant since the last ice age (2.6 million to 11,700 years ago) may only need a few months to reactivate, according to a …

Ancient life has been resurrected from the bowels of a military tunnel that penetrates the Alaskan permafrost. Some of the microbes thawed from these long-frozen soils have been trapped for 40,000 years. Now, they’ve been reawakened. “These are not dead samples by any means,” says microbiologist and geochemist Tristan Caro, a PhD student at the University of Colorado Boulder (CU …

Summary: In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior. By sequencing over 5,000 microbial genomes—including 3,500 never before reported—they linked single nucleotide variations (SNVs) in microbes to neurobehavioral traits and plasma metabolites tied to brain function. These SNVs, mainly within Firmicutes and Bacteroidetes, were found to alter metabolites …

At the US Army Corps of Engineers’ research facility in central Alaska, a unique tunnel descends underground. Measuring over 350 feet deep, mammoth bones jut out from its surrounding walls. However, a team of researchers didn’t go to the remote site for ancient fossils. They were hunting for something much smaller—and smellier. “The first thing you notice when you walk …

Known as a “silent killer,” pancreatic cancer mostly creeps in quietly with almost undetectable symptoms, and yet remains a significant health challenge across the globe. With over half a million new cases and an almost equal number of deaths worldwide in 2021, this disease is a concern with increasing incidence and mortality rates worldwide.Pancreatic cancer is often considered deadly due …

Summary: A new study shows that bacterial cell wall molecules, specifically peptidoglycan, are present in the brain and fluctuate with sleep cycles. This finding supports a hypothesis that sleep is not solely brain-regulated but arises from the interplay between the body and its microbiome. Researchers propose this “holobiont condition” model, where microbial and neurological systems together govern when and how …

Pancreatic cancer, known as a “silent killer” that mostly creeps in quietly with hard-to-detect symptoms, remains a significant global health challenge. With 508,533 new cases and 505,752 deaths worldwide in 2021, this disease is a significant global health challenge with increasing incidence and mortality rates worldwide.World Alzheimer’s Day 2025: The first signs families often missPancreatic cancer is often considered deadly …
