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.
This Is The Best Diet For Stronger Bones During Weight Loss, Per Research
New research published in JAMA Network Open shows that overweight older women who combine a Mediterranean‑style diet with a 30 % calorie cut and regular resistance‑focused exercise maintain higher bone density than those on diet alone. The year‑long trial of 924 Spanish adults found stronger lumbar spine bones in the diet‑plus‑exercise group, a benefit that persisted for three years. The findings suggest a feasible strategy to counteract bone loss often seen during weight loss, especially for patients using GLP‑1 agonists. Experts stress that adequate protein, calcium, vitamin D and consistent strength training are key to preserving skeletal health.
Psilocybin Doses Cut Sperm Motility by Half
Two doses of magic mushrooms degraded my sperm count from the 99.6th percentile to the 77.7th. This may be a first-in-human observation. Context: we ran the most quantified magic mushroom (psilocybin) experiment ever conducted. We were asking if psilocybin is...
