What's Lurking in Your Tap Water?
A reader's question about nitrosodimethylamine in chlorinated water sent me down a rabbit hole. I often mention nitrosamines when discussing cured meats or tobacco, but I've never done a full overview for our community.
These compounds are everywhere, quietly forming from common pollutants. It's a recurring toxicological theme that deserves a closer look.
So, let's fix that. Here is the full breakdown:
💠 Can a crystal have different magnetic properties in alternating domains?
👉 Check out in our latest work, how close we can get to such scenario. A "topotactic jump" into a miscibility gap allows #synthesis of metastable crystalline spinel nanoflakes with alternating ferri- and antiferromagnetic domains.

This is pretty neat: micro-bubbles of methane rising through water can generate spontaneous electric discharges. Which could be the cause of will-o'-the-wisps.
