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 House Design Can Curb Childhood Illnesses in Africa
Researchers in Tanzania tested 110 prototype "Star Homes" featuring screens, rainwater collection, and cement floors against traditional mud-and-thatch houses. Over a three‑year period, children in the Star Homes experienced 44% fewer malaria cases, 30% fewer diarrheal episodes, and 18% fewer respiratory infections. The study, published in Nature Medicine, suggests that modest housing upgrades can dramatically lower the leading causes of under‑five mortality in sub‑Saharan Africa. Each unit costs about $8,800, raising questions about large‑scale affordability.
Semaglutide Drives Significant Fat Loss in Bariatric Non‑responders
For patients who did not respond well to bariatric surgery, semaglutide shifted weight loss far beyond placebo over 68 weeks. Most of that loss came from body fat rather than muscle. obesity
Moderate Sex Frequency Minimizes Heart Risk, Extremes Harmful
Americans who had sex 1-3x/week (52–103x/year) had the lowest risk of cardiovascular disease and death.
