There’s a lot of physics going on inside a cold glass of beer. This is especially the case right after the initial pour, when ...

Beer is one of the world's most popular drinks, and one of the clearest signs of a good brew is a big head of foam at the top ...

In our article “The hidden subtlety of beer foam stability: A blueprint for advanced foam formulations” (Phys. Fluids, 2025), ...

Scientists have cracked the mystery of beer foam, revealing how proteins and physics keep some bubbles lasting longer than ...

On a warm evening, a freshly poured beer can look perfect, topped with a thick cap of foam. Yet that foam, known as ‘head’ ...

Researchers have deciphered why beer foam is stable. In lager beers, viscosity ensures stability, in Belgian ales a complex ...

UNC-Chapel Hill researchers have discovered an unexpected horizontal galloping motion in air bubbles when shaken vertically.

In the paper, published today (04/02/2025) in Nature Physics, the team explain how they used the machine to mimic the behaviour of bubbles in a false vacuum.

And in a bit of visual pyrotechnics, because they understood the physics of the bubbles’ surfaces so well, they were able to overlay a realistic sunset on each one, as if it were being reflected.
