Historically, most people started their days when the sun was up and ended their days when the sun set. But new research from Carnegie Mellon University suggests that some of the body's most important timekeepers live in the gut . A study led by Zheng Kuang, the Eberly Family associate professor in the Department of Biological Sciences , showed that gut bacteria can detect when people eat and send signals that help intestinal cells absorb nutrients at the right time of day. The findings reveal a previously unknown link between the microbiome, circadian rhythms and metabolism. Read more

Courtesy Manel Esteller) When a supercentenarian , someone who is older than 110 years old, is interviewed, they are inevitably asked to share their tips for longevity . But what if their secret could be studied scientifically? What could their genome tell us about ageing and why they avoid the diseases that claim so many other people? If any secrets were uncovered, might they, perhaps, help others to live as long, too? Questions like these are at the heart of a recent paper, published Wednesday in the journal Cell Reports Medicine , which investigated the genome of Maria Branyas Morera , a US-born Spanish woman who died in August 2024 at age 117 years and 168 days, shortly after becoming the world’s oldest living person.

Credit: Hudson Institute of Medical Research The more diverse species in your gut, the better it is for your health. Now an international team led by the Hudson Institute of Medical Research has found a way to determine which species are important and how they interact to create a healthy microbiome . Understanding these relationships opens the door to a new world of medical opportunities for conditions from inflammatory bowel disease to infections , autoimmune diseases and cancer s. Associate Professor Samuel Forster and his team at Hudson Institute of Medical Research, working with collaborators from the Institute for Systems Biology in the U.S. and local collaborators at Monash University and Monash Health, have spent years stud...
