Inflammation
Inflammation: The Silent Fire Inside the Body
Acute inflammation heals. Chronic inflammation corrodes. The line between them runs through the gut wall — and the bacteria on the other side of it.

Blue Zones
What the Blue Zones Teach Us About Healthspan
Sardinia, Okinawa, Loma Linda, Nicoya, Ikaria — what these long-lived populations have in common, and which lessons survive the move from anthropology to clinic.

Sleep
Can Sleep Change the Microbiome?
The microbes follow a clock too. New research suggests the gut–brain axis runs on a 24-hour rhythm — and that even one bad night may register at the bacterial level.
