Narwhals in channels and pipes at #APSDFD2025

Have you ever wondered what narwhals and blessings have to do with viscoelastic flows? Our latest preprint has it all :) arxiv.org/abs/2509.03175

1st day of the Workshop on Complex Flows and Complex Fluids #CNR within #SmartTurb @erc.europa.eu 100+ senior and young scientists working on #turbulence #activematter #biofluids #microfluidcs with equation based and #AI tools. A lot of fun. see biferale.web.roma2.infn.it/ComplexFlows...

According to Financial Times, this puzzle was used by Dominic Cummings to select ‘innovators’ and ‘disruptors’ to work for the British Government. I guess when areas do not have units, missing a few zeros in one’s budget is not such a big deal…

Out today in Phys. Rev. Research, we ask "how does an active nematic fluid respond to a deformable body or boundary?" We were pretty amused by a few observations. 1/20 journals.aps.org/prresearch/a...

Congratulations to our 2025 class of SoR Fellows! Fellows will be inducted in our Oct Annual Meeting in Santa Fe #SoR02025. Join us there to celebrate Paulo Arratia @arratiapaulo.bsky.social, Randy Ewoldt, Anke Lindner, Joao Maia, Matteo Pasquali, Fernando Pinho, and Patrick Spicer! #everythingflows

Happy to share our recent preprint on (the absence of) giant number fluctuations in microswimmer suspensions. arxiv.org/abs/2503.18068

Some pictures from yesterday’s Wim-van-Saarloos-70-fest at the Dutch academy @knaw-nl.bsky.social. Happy birthday, Wim! NB it’s the same room as where Pauli received his Lorentz medal.

Mooie dag vandaag bij de @knaw-nl.bsky.social. Oud-voorzitter Prof. Wim van Saarloos is vandaag 70 geworden en hij wordt geëerd met een symposium. Wim heeft enorm veel bijgedragen aan de natuurkunde en aan de NL wetenschap in het geheel. Van harte, Wim!

It is a great honour to take up the Tait Chair of Mathematical Physics at @edinburgh-uni.bsky.social. I will arrive in June 2025. www.ph.ed.ac.uk/news/2025/ch...

🚨🚨Please repost!! 📢📢 Following last year’s success, International workshop Physics of Biological Systems is back in May! Free registration! Submit talk or poster abstract. Join us in Edinburgh @edinburgh-uni.bsky.social bit.ly/EdinPBS2025

Celebrating two fantastic colleagues tonight at #NWOPhysics. With the Athena award for Prof. Liesbeth Janssen and the Minerva prize for Prof. Hanneke Gelderblom, this is a great evening for TU Eindhoven! ⚛️

Together with the Isaac Newton Institute, we are running a programme aiming to help Ukrainian researchers in mathematical sciences. Please help to spread the word.

Bacterial rheotaxis is ENHANCED in non-Newtonian fluids! This work is in collaboration with Arnold Mathijssen and Albane Thery. Read more about our experiments and simulations in our new PNAS manuscript at pnas.org/doi/10.1073/... @sorheology.bsky.social @pnas.org

Our paper on Majorana quasiparticles in active nematics is out. www.pnas.org/doi/10.1073/...

We are inviting applications for the 2025 Elizabeth Gardner Fellowship targeting early-career physicists from under-represented backgrounds. Please help to spread the word. www.ph.ed.ac.uk/research/res...
