At small scales gravity shouldn't matter - these protein drops, however, start off spherical but change shape as they evaporate depending on the direction of (weak) gravity. Find out more at: go.aps.org/3IEpwXF

Band-aids are flat, but knees are curved; this geometric incompatibility means blisters often form, but when depends on how bendable the band-aid is, as shown in this new study pnas.org/doi/10.1073/pnas.22…

Our paper on why coffee rings are dark + thick in sharply concave regions, but light + thin in convex regions, is out now @JFluidMech (with @MathsMoore ) - see the pic. The big surprise is that this is true even for constant evaporation rate…

Scientists have long tried to create objects that can transform their shape, so-called morphing structures. But this is problematic. Just think about wrapping an orange with a piece of tissue paper: extra area has to be wasted in folds. Our way around: maths.ox.ac.uk/node/40772

Beautiful work (literally) from PT Brun and colleagues!
Fresh off the press: nature.com/articles/s41586-0… Soft robots are "life-like" robots 🦑🤖. Our "bubble-based" method is an easy way to fabricate and program them, e.g. to fetch a ball (w/@Trev_J_Jones , @EJambonP and @biosoftact). @Nature

A good opportunity to listen to @Mingchao_Liu talk about his elegant work (see: doi.org/10.1039/D0SM00714E to get a flavour)
Really look forward to this event!

Want to make a map that folds into a globe? If you have paper with the right thickness profile then by cutting many petals of a given shape, you can get arbitrarily close. Find out more at: doi.org/10.1039/D0SM00714E (with @Mingchao_Liu )

How does the geometry of soft membranes in lymphatic channels optimize the transport of lymph and how a better understanding of this mechanism could lead to new microfluidic and soft robotic systems? More info here: journals.aps.org/prfluids/ab…
