🦃🍽️ This Thanksgiving, your gut barrier is working harder than the chef. A new review by Mak et al shows how alcohol and inflammation weaken intestinal junctions—leading to “leaky gut,” endotoxemia, and widespread metabolic trouble. Read more: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

🐊 Largest survey of skeletal disease in living crocodilians! Nearly half showed osteopathologies, w/trauma most common. Skulls were hit hardest, and non-traumatic issues like inflammation and joint degeneration rose w/size & age.
