In a mouse study conducted by scientists at the Dasman Diabetes Institute in Kuwait, rodents fed a sucrose-free diet developed insulin resistance, gut microbial imbalances and signs of fatty liver disease despite maintaining similar body weight.
A surprising study found that cutting out sugar completely may disrupt the gut microbiome and worsen metabolic health. Cutting sugar out of your diet entirely may not be as beneficial as many people assume. New research in mice suggests that completely eliminating sucrose could have unintended effects on gut health and metabolism. The findings were [...]
Tiny particles from the gut may be carrying aging signals throughout the body, offering a surprising new clue to chronic disease. Researchers at the Marshall University Joan C. Edwards School of Medicine have uncovered new evidence that microscopic particles produced in the gut may contribute to the inflammation and chronic diseases often associated with aging. [...]
A surprising gut-brain discovery suggests that anxiety could one day be treated with specially designed probiotics. Could anxiety be shaped, at least in part, by tiny organisms living in the gut? Research from Duke-NUS Medical School and the National Neuroscience Institute of Singapore points to a striking connection between gut microbes and anxiety-related behavior. The [...]
Ötzi the Iceman, Europe’s most famous mummy, is crawling with microbes, some long dead, some still eking out a living after thousands of years, and some very modern.
After he died in the Ötztal Alps, the Copper Age man now known as Ötzi lay alone and forgotten for 5,300 years, until a group of hikers stumbled on his freeze-dried remains in 1991. Since then, he’s received a lot of attention from scientists, who have sequenced his DNA, pored over his last meal and the remains of his gut microbes, and examined his clothes and his broken tools. Today, Ötzi lies in a high-tech resting place at the South Tyrol Museum of Archaeology in Italy, where, it turns out, his body is still home to a handful of cold-adapted yeast species that have probably been with him since just after he died.
Slightly morbid souvenirs from the Alps
Microbiologist Mohamed S. Sarhan (of the Institute of Mummy Studies at the private Eurac Research center) and his colleagues recently sampled material from Ötzi’s stomach and meltwater from inside his body, swabbed his skin, and even sampled airborne microbes from his frozen storage room and the lab outside it. They also took samples from a block of frozen alpine soil taken from next to Ötzi’s body back in 1991.
Scientists restored young gut bacteria in aging mice and saw signs of rejuvenation along with complete protection from liver cancer. Returning the gut microbiome to a more youthful state could help slow aging and lower the risk of liver cancer, according to research entitled “Restoration of a youthful gut microbiome reduces liver aging and suppresses [...]
