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… #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/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…
This quoted post is unavailable.
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!

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
Some more nice work from the thesis of @AlexBradley14 is now published!

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-chart/…
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.
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).

Our recent paper about the snap-through in #Graphene #nanochannels just published in @ACS_AMI. We investigate the fluid-solid coupling #instabilities at nanoscale, and demonstrate the application in #fluidic control and #molecule selection. Link: pubs.acs.org/doi/10.1021/acs…
