Let's learn some surprising things about hummingbird tongues.

First, as you can see, their tongues are forked & feathery, highly specialized for lapping up their liquid diet of nectar.

But it gets weirder up close!

Tiny water droplets naturally form perfect spheres. If droplets look too perfectly round and evenly sized, you’re often looking at physics doing its thing.

S. gordonii is a pioneer colonizer of dental plaque. It’s
one of the first bacteria to settle on clean tooth enamel and
helps other microbes move in later. Basically, it throws the
house party 🦠🦷

The tiny hairs on Frauenmantel leaves, together with a wrinkled micro-surface, trap air and make the leaf extremely water-repellent β€” that’s why droplets sit on top instead of soaking in!

Electrochemically grown silver dendrites

Just like ice crystals, these are crystals formed when silver solidifies very quickly from a solution, for example, during electrolysis

Added the finishing touches to my presentation for today's #F25MRS SB03 session at 13:45 (room H105)

The Engineered Living Materials talks in this symposium have been really inspiring and I'm most looking forward to the therapeutic living materials sessions today!
