Does viscoelastic confinement physically alter cell proliferation? Sree @padmanabh97 & @Mridul_Gautam01, along with @bagade_nikita18 & Sunil Laxman, discovered a 3D confinement-driven cell cycle regulation in budding yeast. (1/9) @NCBS_Bangalore @ESoftbio tinyurl.com/esoftbio20252

Interested in living/active matter? I will be giving a @RoySocChem "desktop seminar" webinar on August 5, describing our recent work studying bacterial growth in complex fluids, along with my friend & intellectual hero Kate Stebe (U. Penn)! Register at: rsc.zoom.us/webinar/regist….

Previous @SciCommAwards winners @stevenstrogatz, @BhamlaLab, and @inthosegenespod discuss the importance of the physical sciences to our daily lives and their role in answering some of the biggest questions we have about our universe. Watch here: youtu.be/sKeNfJTMb-Y #scicomm

The SoR Community Development Committee is seeking professional rheologists at all career stages working in industrial, academic, and government sectors who are interested in mentoring students and early career rheologists at or before the 2025 Annual Meeting in Santa Fe. (1/3)

Worm clusters, jellyfish tentacles, robotic arms -- what do they have in common? Our new study in @NatureComms reveals how active movement leads to entanglement and stiffening -- offering new insights into polymer physics. nature.com/articles/s4146… #PolymerPhysics #ActiveMatter

Our June Editorial highlights our dedicated monthly column, By the Numbers, which covers dimensional analysis and scaling as applied to chemical, biological and numerical processes and systems. Read more here (🔓): nature.com/articles/s4428…

We have an exciting set of Area 1J sessions covering all areas of fluids & transport: *Mon 11/3 — Faculty candidates & plenary speakers describe new frontiers *Tue 11/4 — Sessions honoring Andy Acrivos + regular sessions *Wed 11/5 — Regular sessions See y'all in Boston this fall!

Registration is Now Open for the 2025 AIChE® Annual Meeting! The must-attend conference for chemical engineers, R&D scientists, and academic leaders at all career stages. Join a vibrant global community this November in Boston: bit.ly/463pyVt #AIChEAnnual #AIChE2025

A vital and very enjoyable component of my academic work is teaching students at all levels how to extend the frontiers of knowledge. So I’m pleased to announce a set of Jupyter notebook tutorials organized around our ideas for “physics of behavior”: github.com/oist/Physics-o…

Thrilled to see this paper published @softmatter! Check it out at doi.org/10.1039/D5SM00…. In it, we describe how the unique rheology of wormlike micelle solutions influences their unsteady flow through windy serpentine channels. Summary in the tweetorial below ⬇️

Trying to anticipate how bacteria will spread is like predicting the flight of a leaf in a windstorm — it’s complicated and chaotic. However, a new #FlatironCCB study presents a computational method for predicting how bacteria navigate obstacles: simonsfoundation.org/2025/03/21/new… #science…

PhD student Michelle Quan's review article on “Biomolecular Actuators for Soft Robots” was selected for the cover of Chemical Reviews! Michelle highlights the history and new frontiers for biomolecules as tools to actuate movement in soft robots. #MyACSCover @ACSPublications

Are you a student or postdoc working on theory for biological problems? Just over two weeks left to apply for our fall workshop here at @HHMIJanelia. It’s free and we cover travel expenses! janelia.org/you-janelia/co…

The latest work from my lab, Phage Disco, a method @EllieRand3 developed for targeted discovery of bacteriophages based on the bacterial receptor, defense system, or other component they interact with, is now live in mSystems

Join us in celebrating Jean Tom, our May Donor of the Month! 🌟 Her dedication kickstarted the 35 Under 35 Award Endowment, ensuring lasting support for emerging chemical engineering leaders. 👏 Learn more ➡️bit.ly/3Hmlzch @Princeton

The nonlinear mechanical properties of soft biological tissues and composites are poorly understood. Their strain stiffening under compression and shear is now found to be universal, and follows from the physics of the underlying biopolymer matrix. nature.com/articles/s4156…

The height and position of the loss modulus overshoot during yielding of yield-stress fluids are controlled by linear viscoelasticity Letter: go.aps.org/3Zw2ef3 Focus: go.aps.org/4kB5vlr
