When swarms of bubbles are driven upwards through a fluid by their buoyancy, they can generate complex flow patterns in their wake. Named 'pseudo-turbulence,' these patterns are characterized by a universal mathematical relationship ...

It's widely known that thick, viscous liquids—like honey—flow more slowly than low-viscosity liquids, like water. Researchers were surprised to find this behavior flipped on its head when the liquids flow through chemically ...
