I gotta make a note of this one.

Scientists have unveiled the sharpest images ever captured of a solar flare. Taken by the Inouye Solar Telescope, the image includes coronal loop strands as small as 48 kilometers wide and 21 kilometers thick--the smallest ones ever imaged.

Happy to combine two of my favorite things: fountain pens and giving genAI two middle fingers.

Off western Australian, hundreds of low-lying islands and coral reefs jut into the ocean as part of the Buccaneer Archipelago. Tides here have a range of nearly 12 meters, so water rips through the narrow channels as the tide ebbs and flows.

To understand how changing sea ice affects climate, researchers need to tease out the mechanisms that affect sea ice over its lifetime. A new study does just that, showing that sea ice loses salt as it ages, in a process that makes it less porous.

Although wind turbines can have any number of blades, most that we see have three. The reasons for that are many, as explained today's Minute Physics video.

In kirigami, careful cuts to a flat surface can morph it into a more complicated shape. Researchers have been exploring how to use this in combination with flow; now they've created a new form of parachute.

It's like the patriarchy does men a disservice by defining their identities solely through protecting and providing.

There's a simultaneous thrill and dread when reading a paper's literature review doubles the number of articles in your Zotero folder. #bookwriting #scicomm

Today is the kind of day where my reading jumps from how a flock of hungry sheep passes through a barn door to how manta rays filter their food without ever clogging. #bookwriting is wild, folks #scicomm

I love this idea and these gems.

As the implications of climate change grow more dire, interest in geoengineering--trying to technologically counter or mitigate climate change--grows. #climatechange #fluiddynamics #geoengineering #science

The loud noises of construction are not just an issue for humans. Sound and pressure waves from underwater construction are a problem for water-dwellers, too.

As children, most of us plant a seed or two and watch it sprout, but we never get a view quite like this one. #biology #fluiddynamics #physics #plants #science

Look beneath the waves on a beach or in a bay, and you'll find ripples in the sand. Passing waves shape these sandforms and can even build them to heights that require dredging to keep waterways passable to large ships.

Ngangla Ringco sits atop the Tibetan Plateau, breaking up the barren landscape with eye-catching teal and blue. This saline lake sits at an altitude of 4,700 meters, fed by rainfall, Himalayan runoff, and melting glaciers and permafrost.

When a strong earthquake causes liquefaction, sand can intrude upward, leaving behind a feature that resembles an upside-down icicle. Known as a sand dike, researchers suspected that these intrusions could help us date ancient earthquakes.

In an earthquake, sand and soil particles get jostled together, forcing any water between them up toward the surface. The result is liquefaction.

In the 1920s, the world saw a new sort of marine propulsion, ships with one or more tall, smokeless cylinders. These Flettner rotors, named for their inventor, would spin in the wind, generating lift to propel the boat, much as a sail would.

Although they're iconic, arch dams like the Hoover Dam are relatively unusual. In today'sPractical Engineering video, Grady looks at the forces a dam needs to withstand and where and why an arch dam is useful. #civilengineering #physics #science
