The tiniest engine on Earth#learnontiktok #atpsynthase #flagellum #biotok #funfacts #biology #nanomachine #learning #molecularbiology #coolscience #scienceanimation #molecularmotor #stem Powered by a natural outboard engine, a bacterium relies on flowing protons to spin its flagellum hundreds of times a second through water. Inside, thousands of nanomachines operate in a dense labyrinth of DNA that spans a thousand times the cell's length. As food grows scarce, surface receptors trigger a messenger that reverses the motor. The cell tumbles, recalibrates, and races off in a new direction. By repeating this cycle, these invisible organisms successfully hunt for food and navigate their environment.

40 Ways Light Can Bend, Bounce and Break ✨ How does a lens focus light? Why does a diamond sparkle? Where do rainbows come from? 🌈 40 optical elements, one beam of light at a time 🔦 Every ray path follows real optics: Snell’s law, reflection, total internal reflection and dispersion. 🔍 Lenses: convex, concave, meniscus, aspheric, Fresnel, GRIN 🪞 Mirrors: plane, concave, parabolic, elliptical, Mangin 🔺 Prisms: right-angle, Dove, penta, rhomboid, beam splitter 💎 Light in nature: water droplets, diamonds, hot-air mirages 🌈 Splitting white light: Newton’s prisms, diffraction grating Which one surprised you most?

Capybaras bark to alert the rest of the herd to potential danger. Cheesecake usually only barks when she sees a person she’s never met before… but I’m still not sure what she was barking at 😬 What do you guys think she was worked up about? #capybara #capybaras #didyouknow #funfacts #animals
