🚨 Imagine a bacterium that refuses to follow the textbook:
It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks.
Meet Litorilinea aerophila — and here’s why it blew our minds.

We challenge the long-standing view that peptidoglycan alone protects cells from bursting.
Our study shows that the periplasm — enclosed by OM–PG connections — acts as a pressure buffer essential for osmoprotection in Gram-negative bacteria.

Peptidoglycan–outer membrane attachment generates periplasmic pressure to prevent lysis in Gram-negative bacteria - Nature Microbiology
Outer membrane attachment to peptidoglycan enables periplasmic pressure to build up and counter cytoplasmic turgor pressure, preventing lysis during osmotic challenges in Escherichia coli.

New, from an anonymous NIH insider: Trump is being pushed to spend more NIH money. The White House is ordering NIH to do multi-year budgets for awards. This budget trick means fewer awards, fewer labs funded, and lower paylines for researchers. 🧵
