💁🏻♀️ ICYMI: 🕯️🔈 Physicist Dr. Helen Czerski uses a stethoscope on tree bark and candles in an anechoic chamber to show how #sound is a physical movement of #air molecules. Watch how flames flicker in sync with specific frequencies to make invisible sound waves visible!

Thunderstorms conjure ghostly coronae in treetops, observed outdoors for the first time https://phys.org/news/2026-02-thunderstorms-conjure-ghostly-coronae-treetops.html paper: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL119591
"For the first time, researchers have observed and measured weak electrical discharges on #trees during #thunderstorms. A new study describes the near-invisible sparkles appearing similarly on branches of several #tree species... implying that thunderstorms may paint entire canopies with a scintillating blue glow, too faintly for human eyes to see"

for our next contestant, the mysterious black-billed mountain toucan prides herself on her ability to move unseen through the magnificent greenery of the cloud forest...
OOPS...
🤣
her red butt gives away the whole show!!!

🦌✨ White-tailed #deer mark #trees and the ground with scents, but new #research shows these spots also glow under UV light.
Since deer have eyes tuned to these wavelengths, they are essentially creating "hidden" signposts to communicate with each other during the dim light of dawn and dusk.
