Gut microbes may dictate cellular aging, new review suggests
A Frontiers in Aging review introduces the microbiome‑gerogene axis, proposing that gut microbes act as upstream regulators of cellular aging networks. Age‑related dysbiosis reduces key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors highlight precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.
How 2 Men Smashed Through a Marathon Barrier Long Thought Unbreakable
Kenya’s Sabastian Sawe and Ethiopia’s Yomif Kejelcha shattered the long‑standing two‑hour marathon barrier at the London Marathon, with Sawe clocking 1:59:30 and Kejelcha 1:59:41 in his debut. Sawe’s time sliced 65 seconds off the previous world record, while third‑place Jacob Kiplimo also beat the old mark. The performances were underpinned by extreme training volumes, meticulous carbohydrate fueling, and the lightest Adidas Adios Pro Evo 3 supershoe. Ideal weather and a fast course completed a perfect storm for the historic breakthrough.
