The Macro room team is back with a video featuring their signature colorful cleverness. This time they're using a magnetic stirrer to swirl up some mesmerizing flows. It's well worth a watch.

Stars about eight times more massive than our sun end their lives in supernovas, incredible explosions that rip the star apart. The earliest stages of this explosion are something we've never observed firsthand, until now.

Every time I fill a glass at my refrigerator, I watch how the falling jet creates a cloud of bubbles. The bubbles form when the impacting water jet pulls air in with it, though, as this video shows, the exact origins can vary.

The Rayleigh-Taylor instability--typically marked by mushroom-shaped plumes--occurs when a dense fluid accelerates into a less dense one. But researchers have now demonstrated the effect at quantum scales, too.

Fresh snow shines white on the southern end of Greenland in this satellite image, taken in late February 2025. Whorls of sea ice sit off the coast, where they trace out patterns that reflect the winds and ocean currents of the region.

It's difficult at times to fathom the scale and power of fluid dynamics beyond our day-to-day lives. Here, twists of the Sun's magnetic field propel a jet of plasma more than 500,000 kilometers out from its surface in an enormous solar prominence eruption.

Photographer Ernie Button explores the stains left behind when various liquors evaporate. This one comes from a single malt scotch whisky by The Balvenie. The stain itself is made up of particles left behind when the alcohol and water in the whisky evaporate.

When supercooled, water can remain a liquid even below its freezing point. As explained in this Minute Physics video, this happens because of a tug-of-war between effects in the water. #physics #science #supercooling

Taking a deep breath may actually help you breathe easier, according to a new study. When we inhale, air fills our alveoli--tiny balloon-like compartments within our lungs. To make alveoli easier to open, they're coated in a surfactant chemical produced by our lungs.

To form planets, the dust and gas around a star has to start clumping up. While there are many theories as to how this could happen, it's a difficult process to observe. A recent study shows that a magnetorotational (MR) instability could do the job.

We spend our lives dealing with fluids at a scale where the motion of individual molecules is beneath our notice. But once you are dealing with pipes that are small enough--below about 1 nanometer in diameter--fluids have to be considered molecule-by-molecule.

Onions are a well-known source of tears for many a cook. And while the chemical source of their power--onions release a chemical that reacts in our eyes to produce tears--has been known for years, no one has looked at the fluid dynamics in the process until now.

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.
