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

WE'RE RETURNING FOR 2023! You are now able to book for the Oxford Maths Festival, taking place 13-14 May. It's great for families with kids aged 5-13. Take a look at our programme for this year and get yourself booked. mathsfest.web.ox.ac.uk/whats-on #Maths #Family #OxMathsFest

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/pn…

Prof Dominic Vella @MathObservatory giving yet another high quality seminar in our new series on Math Modelling of #FluidMechanics for Aus/NZ — this time on various surface tension driven phenomena from capillary imbibition to drops on surfaces

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…

We have a post-doc opening in collaboration with @img_oxford and Janine Nunes (Princeton). More details: my.corehr.com/pls/uoxrecruit…

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:

Beautiful work (literally) from PT Brun and colleagues!

Fresh off the press: nature.com/articles/s4158… 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

@Andreotti_B @rebeccahoyle @GilesWiggs @TLS_Queen No problem. It would be interesting to compare with data from Scotland if you can get it: their schools go back for the first time since Dec 2020 today. Even so, their all-age data shows a rise in cases during March, see ig.ft.com/coronavirus-ch…
English
@Andreotti_B @rebeccahoyle @GilesWiggs @TLS_Queen Also, just FYI, school holidays are not uniform across the country. Some authorities closed schools on 26/03 I think but ours was 31/03.
English
@Andreotti_B @rebeccahoyle @GilesWiggs @TLS_Queen it could be the face mask difference: the 10-14 year old bracket includes those in years 5 and 6 (no face masks) and those in years 7-10 (face masks). The distinction seems to be on the basis of year group, not age, see: gov.uk/government/pub…
English
@rebeccahoyle @Andreotti_B @GilesWiggs @TLS_Queen Yes, and year 12 to age 24 is ages 17-24, so the vast majority are out of school. I guess the timing of the peak here is less to do with term end (earlier than 20th Dec in most unis) and more to do with mixing in the run up to Xmas and Xmas itself (followed by rule changes).

A good opportunity to listen to @Mingchao_Liu talk about his elegant work (see: doi.org/10.1039/D0SM00… to get a flavour)

Really look forward to this event!
