Here are the three new-to-me games which I enjoyed most this year (feat. games by @mathieujohnson.bsky.social @sespagnolie.bsky.social @gmtgames and others)! What were yours?

🚨 POSTDOC OPENING 🚨 NIH-funded Bio-Fluid Mechanics Postdoc in my lab @univmiami.bsky.social Hofstenia miamia | cilia-driven flows | behavior & neuroscience Collab w/ Mansi Srivastava @harvard.edu 🕒 Start: Jan–Feb 2026 ⏳ 1 yr, renewable | Email me ASAP! #Postdoc #Biophysics #FluidDynamics

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

I am looking to hire a postdoc to work with me on fluid-structure interactions in complex and active fluids. Ideally the candidate will have a strong background in numerical/asymptotic analysis and fluid mechanics (complex fluids / LCs even better). www.mathjobs.org/jobs/list/26...

🚨Fully funded PhD opportunity: Physics, biology & ecology of toxic dinoflagellate blooms 🦠. Join us to investigate how motility and mixotrophy influence bloom formation, using experiment🔬and modelling ♾️. #microswimmers #plankton #biophysics #ecology #PhD pls RT iapetus.ac.uk/studentships...

NSF email to GRFP applicants from TODAY: you MUST submit official academic transcripts with your most recent academic status! First year PhDs often don't get these until the end of this semester. No clarification opportunity because of government shutdown. Application deadline is next week. 🫠

Not *one* mention of Plateau-Rayleigh in this article.

Really excited to present the results of a fantastic collaboration with Jesse Veenvliet @jesseveenvliet.bsky.social @mpi-cbg.de @poldresden.bsky.social 🤩 We find a unique mechanism for body axis elongation in mammals, different from other vertebrate species ➡️ www.biorxiv.org/content/10.1...

Maybe you know someone who wants to support state school higher ed? There are many ways. Here's one. uwflamingos.com/campaign/mat...

Psst, your students want to hang out in Boulder next July. Application deadline is Jan. 15. www.colorado.edu/conference/b...

Astounding!! This must have been so much fun to explore. I enjoyed the short Bluetorial as well.

Me: Describes the Ship of Theseus. Wife: "Oh it's Van Halen."

Some of us had the day off from work so we got Vijayanagara from @gmtgames.bsky.social on the table at the club.

Without describing the experiment (soon!), please just enjoy with me a case where a simple model meets the data this well. Oh man. Math, I tell you. Good stuff.

I am super excited to announce that we have a tenure-track faculty position in biophysics open in the Department of Physics at Carnegie Mellon! 🧪 Interfolio link: apply.interfolio.com/174360 PLEASE, share widely across the blue skies! Let me briefly explain what we're looking for: 1/10

Friends in Canada and Europe are asking me if it's safe to travel to Houston this November for the big annual conference in our field.

If you see this, quote the energy you bring to Bluesky.

What poster did you have hanging in your room as a kid?

Choose your weapon.

Ruin a book by adding Tom Clancy’s name to the title Tom Clancy’s Principles of Mathematical Analysis

Dublin has been so weird this week.

New York

These are the most challenging times for early-career scientists and engineers. My team is doing its bit to help by maintaining and even expanding our database of funding opportunities for early-career researchers. We found 437 of them. Download it freely here: research.jhu.edu/rdt/funding-...

Out today in Phys. Rev. Fluids, our 'Arrested development and traveling waves of active suspensions in nematic liquid crystals'. The bend instability in active suspensions pairs off against bending resistance in LCs to tell quite a story! 1/20 people.math.wisc.edu/~spagnolie/P...

Who can I look forward to seeing in Dublin next month? www.efdc2.com

This is a remarkable paper, or probably many papers squeezed into one. I cannot help but be amused that sperm hyperactivation (a swimming state with large amplitude, asymmetric flagellar beating) can be triggered by... caffeine.

Gordon Research Conferences way station - a hotel near Boston Logan. Different shuttles heading off to different week-long meetings. Pretty neat!

Love is a tendril perversion.

Nazi Germany did literally ban Nature: "Articles are often published in the London weekly scientific journal Nature containing outrageous and vile attacks on German science and the national socialist state. The journal must therefore be excluded from general use in the scientific libraries."

Dear #mathsky, if you repost this, it will let people see the article for free. Thanks! www.nytimes.com/interactive/...

Spending the longest day of the year with the Figueroa group in beautiful Boulder. The city has changed a ton over the years, but I appreciate that KBCO still has Alanis Morissette on repeat.

What is common knowledge in your field, but shocks outsiders? You can (sometimes) determine whether an equation has a solution or not even if you can't find it. I don't actually know if this shocks outsiders. At best it might elicit a "huh". At worst, a yawn, or maybe a punch in the face.

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...

State Street in Madison, WI, packed for a mile from the university to the capitol. Many thousands of pissed off, peaceful people out there in the heat today.

The cost of the disgraceful military parade this weekend? $25-45 million, which could have paid for 150-300 NSF GRFPs (3-year-long grad research fellowships). These awards are hugely important for training the next generation of scientists, and for their research areas. www.aps.org/initiatives/...

Over 500 games played in the first few weeks on RTT! Medieval India is hoppin'.

I feel about 100 times more threatened by the current administration's activities than anything I've heard said on campus.

I'm proud to work at an institution that has this plaque posted prominently for all to see. @uwmadison.bsky.social Photo from hannemanarchive.com/tag/sifting-....

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

This is the best tool I've seen for rapidly writing your reps. DO IT! www.aps.org/initiatives/...

When the world gets you down, let the joyful wisdom of Tadashi Tokieda brighten your day. youtu.be/pkfDYOZ1p4Y?...

Those of us deeply worried about the attacks on science are not overreacting. The sum total of what’s been happening is a full on assault on the independence of scientific endeavor. Its goal is not “efficiency.” open.substack.com/pub/christin...

Amazing work by @ccxvii.bsky.social & Co. at RTT (especially Joël Simoneau). Such a high quality implementation, and free! rally-the-troops.com/vijayanagara
