🫧 Particles as different as soap bubbles and ball bearings can be made to arrange themselves in exactly the same way, according to a new study that could unlock the creation of brand new materials — including those with promising biomedical applications.

Impressed with the bubbles at the underwater viewing gallery at Diglis fish pass in Worcester. Good to see lots of fish too.

After a long gestation, a preprint: if the density increases quadratically with an offset, a perimeter-minimizing bubble moves towards the origin as the offset increases, then settles there and shrinks.

Pleased to see Jacob's paper on wet foam coarsening appear in JFM, with predictions for how quickly bubbles grow or shrink. go.shr.lc/3OwHQVv
