DIARY...or some kind of

In this post, I’ll include everything related to my seven pillars (see also How to Live Guide: Practical ). I’ve done this before in an older blog, but that work is unfortunately lost to me for now. So, I’ll simply begin again...starting from today, at random. 7 pillars Mental and Physical Health Artificial Intelligence Finances and Future Relationships, Friends & Family Improving the World: Nature & Humanity How to Live: Practical & Theoretical (Life Hacks, Philosophy, ...) (see here for practical, for theoretical bacgound check out this  link ) Xplore the World & Knowledge Database (series, movies, anime, books, fun facts, interests,...) 24-8-2025 (sunday, free) Mental and Physical Health Nothing particularly noteworthy today. I cleaned my house a bit, brought more order to my kitchen, and did the laundry. I also prepared my bag for work tomorrow. My eating habits weren’t ideal, I even picked up a pitta and some French fries from the local shop. Artificial Intelli...

Cool Fact 1: Magnetoreceptors

 

1: Magnetoreceptors

Some animals have magnetoreceptors in their brains, allowing them to sense Earth's magnetic field. This ability, called magnetoreception, helps them navigate during migration, hunting, or orientation.

Animals with Magnetoreceptors

  1. Birds (e.g., Pigeons, Robins, Geese, Swallows)
    • Some birds have iron-rich cells in their beaks and special cryptochrome proteins in their eyes that react to magnetic fields.
    • This allows them to "see" magnetic fields and navigate across long distances.
  2. Sea Turtles
    • Hatchlings and adult sea turtles use magnetic fields to migrate across oceans and return to the exact beach where they were born.
    • They likely have magnetoreceptors in their brains or nervous system.
  3. Bees & Other Insects
    • Honeybees use magnetoreception to navigate and find their hive.
    • Tiny magnetite (iron) particles in their bodies help detect the Earth's magnetic field.
  4. Fish (e.g., Salmon, Sharks, Rays)
    • Salmon have magnetic sensors in their brains to help them return to their spawning grounds.
    • Sharks and rays detect magnetic fields to hunt and navigate underwater.
  5. Mammals (e.g., Bats, Mice, Cows, Dogs)
    • Some bat species use magnetic fields to migrate.
    • Studies suggest cows and dogs align themselves with the Earth's magnetic field when resting or urinating.
