💁🏻‍♀️ 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!

A woman in a red shirt kneels in an anechoic chamber next to a speaker and many small, lit candles on the floor.

Can you use candles to see sound?

What does a thirsty tree sound like? What can candle flames show us about the way sound travels? What is sound? On a hot day, moving water from a tree's

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"

Beautiful blue sky over John Day Fossil Beds National Monument today. In the center of the image, a brilliantly colored hill topped by a pyroclastic deposit. A small white cloud drifts in the distance on the right. On the left, a tree leans into the scene, green needles spread against the sky. A fence, a road, and a grassy field appear in the foreground. A small building with an array of solar panels can be seen at the base of the hill on the left.

Large rhino-like brontotheres roam a semitropical forest. Dog-sized, three-toed horses dart between the trees. The cat-like nimravid and bear dogs stalk their prey. The climate cools and forests alter to dryer grasslands. Saber tooth cats and camels get replaced by mountain lions and deer. Paleontologists learn more about the ancient animals and environment with every new fossil they discover.

Black and white photograph of a winter landscape, showing a spruce tree on the left and a tree stripped of its leaves on the right, in a snowy field, with a snowmobile trail at their feet at the bottom of the photo. Behind, the snowfield rises and the long shadows of the forest are cast on the smooth surface, forming a curve of tree silhouettes in the upper left corner.

Derrière, le champ de neige remonte et les longues ombres de la forêt sont projetées sur la surface lisse, formant une courbe de silhouettes d'arbres dans le coin supérieur à gauche. — Black and white photograph of a winter landscape, showing a spruce tree on the left and a tree stripped of its leaves on the right, in a snowy field, with a snowmobile trail at their feet at the bottom of the photo.

A serene winter landscape featuring two bare trees reflected in the calm, icy water of a side arm of the river Elbe under a gray, cloudy sky. There is some grass visible between the side arm and the river which seems to be orange die to the season.
In the background you can see trees in a park on the other side of the river in the dust. — A serene winter landscape featuring two bare trees reflected in the calm, icy water of a side arm of the river Elbe under a gray, cloudy sky.

it's time to play Spot the Toucan...

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!!!

A green tree full of branches protrudes over a misty green hillside. To the casual eye, perhaps nothing to see here-- until you notice the fluff of vivid scarlet. Then the entire toucan jumps into shape. This is the Black-billed Mountain-toucan. With her red/black bill and white breast, she just looks like any patch of pattern in the rain forest trees... until you notice the red vent. Our hosts spotted this bird from, like, a mile away. Ha.

🦌✨ 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.

Deer Create Mysterious Ultraviolet Signals That Glow in Forests

Deer have the ability to see ultraviolet light, and a recent study shows they can also leave a glowing trail visible in those wavelengths, too.
