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.
Night Shift Weight Loss: A Practical Fasting Guide for Physicians
Physician Aaron Grubner tested a simple fasting rule—no eating from 8 p.m. to 1 a.m.—while working night shifts. Over eight weeks, his weight fell from an average of 207.2 lb to 202.3 lb, a loss of about 4.9 lb (0.8 lb per week). Daily weigh‑ins showed large fluctuations, but seven‑day rolling averages revealed a steady downward trend. The experiment required only the fasting window, with water, coffee, and diet soda allowed, and no other diet or exercise changes.

SREBP‑2 Links Stress to Cell Death via IRAK1
Researchers found that the cholesterol-related protein SREBP-2 can trigger apoptosis under stress by interacting with IRAK1, revealing a new mechanism for how cells self-destruct. This suggests that beyond telomeres, which signal aging through gradual shortening, cells can also initiate death...
