For the 2026 APS March Meeting, please consider submitting your abstract to our new focus session on Cellular Sensing and Signaling (04.01.29), which aims to bridge theory and experiments to understand how cells sense and respond to environmental signals.

SCHEPHERD--the bioelectric cell herding platform built for YOU. Single cells, monolayers, organoids--this herds them all + new tricks. Plz try it-- we will *give* you parts! Teaser here of a steering a single cell. GS Yubin Lin's lifeblood with J. Yodh on piano; Celeste R. and Paul K. Thread 1/N

I keep reading that it was important to the guy, but feels to me that 100000 Pascal wagers is really only about 1 bar bet

Being a professor is so weird. You are constantly having to act like you know things.

Fun membrane biophysics problem: how long will it take for continental diffusion to mix the continents? (Or for line tension to make their boundaries circular?)

Not quite sure why @aip-publishing.bsky.social has scummy advertising that pretends to be a download link. This isn't ideal for a scientific society. (Brought to you by Chrome no longer supporting adblockers!)

Automated optogenetic control of hundreds of cells in parallel. Each cell is individually steered, collectively acting as a "tissue printer". Preprint & code out! www.biorxiv.org/content/10.1...

Seeking science journalists: @quantamagazine.bsky.social is hiring a physics editor! A rare opportunity to join this great team and lead coverage of this foundational vertical. Please reach out with any questions and share widely simonsfoundation.wd1.myworkdayjobs.com/en-US/simons...

Remebering Paul Kulesa (1962–2025) We honor Dr. Paul Kulesa, whose pioneering work on neural crest cell development has profoundly impacted neuroscience and pediatric cancer research. His loss has deeply impacted the Developmental Biology community and everyone he graced with his presence in life.

I was curious about these failure modes. Surprisingly robust that you get wrong answers but easy to fix. I suspect LLMs are most useful when solutions are easy to check but hard to generate

Fascinating piece of data- capital expenditures from big tech up ~3x in last few years but tech employment is roughly flat/declining over that time, at least per: www.comptia.org/en-us/resour...

New work from Emiliano Perez Ipina + me: if cells respond to chemoattractant A and chemoattractant B, when do they go to source A vs source B? Or do they ever wander back and forth? We show a lot of different options are possible: arxiv.org/abs/2507.19341

Thank you to everyone who has supported TLM talks. We will be back in Ocotber with some new exciting talks. We have plans to incorporate short talks by students and postdocs, fill out this form to express your interest forms.gle/34vMwQNVGnvm.... Have a nice summer 🌅

Powerful story from Kate Zernike from the NYT Covers the diversity of young scientists targeted by the anti-DEI BS. Definitely worth a read and a share. [Gift link] www.nytimes.com/2025/07/10/u...

There is so, so much good science being shared and discussed on bsky right now. The news of its demise is quite backwards. If you are having trouble finding it among all of the very important political news, use the papersky feed that filters posts you follow to just papers: bsky.app/profile/pape...

@sfuscience.bsky.social in Vancouver seeks world-leading applicants in strategic areas that include Biophysics (featuring an internationally recognized and highly collaborative group of researchers centered in @sfuphysics.bsky.social).

Research Saves Lives At Hopkins, we just went live with an expansive website showing the extraordinary value of research, the impact of cuts to research, what's at stake, resources for our research community, etc. Check it out: researchsaveslives.jhu.edu

"I'm still in shock. I know that there have been political issues around Harvard in recent weeks, but antibiotic resistance isn't one of them." My conversation with Harvard microbiologist @baym.lol, one of many researchers there who just lost millions in fed. grants. www.wbur.org/news/2025/05...

Yesterday, the NIH R35 “Outstanding Investigator” grant to fund scientists in my lab studying antibiotic resistance was terminated for reasons not related to the content of the science, or any actions taken by me or members of my lab

The tip of the cantilever consists of a fluorescent bead that contacts the epiblast. Because we know the force necessary to bend the cantilever, we can perform mechanical assays by driving the bead across the embryo and measure in real time the force applied to the tissue.

I work in science, but I really loved National History Day and think it's a great experience for students - and I think helped train my thinking and presenting skills for the job I have now! Might be worth a donation to help make up for their canceled NEH grant.

The preprint of this work is now available: doi.org/10.1101/2025... - this is probably the paper I've been most excited about as a new PI. I will try to write a longer thread later when I have time to focus, but check out the seminar if you want the highlights!

How do cells sense electric fields? How quickly can they respond? We show, in a collaboration with Nathan Belliveau and Julie Theriot, that this is limited by the physics of how proteins diffuse. Here's the @bppbseminar.bsky.social seminar I gave on this work: www.youtube.com/watch?v=5TDX...

Groups of cells can both grow and break apart. What physical factors control these fractures? What sets the eventual size of clusters? Read our paper: arxiv.org/abs/2503.03126

For any of my friends at the #APS Global Physics Summit, come to the Macromolecular Assembly in Cells II session today at 3pm to hear from me about how clathrin self-assembly is tuned to sense cargo receptors!

When cells break off from an invading cancer, is it a single cell or a big clump? This changes how dangerous the cancer is. In Wei's paper, in collaboration w/Kostas Konstantopoulos, we model how groups of cells break off from an invading cancerous front, and see when you get single cells vs groups

Confinement, Jamming, and Adhesion in Cancer Cells Dissociating from a Collectively Invading Strand, W. Wang, R. A. Law, E. P. Ipiña, K. Konstantopoulos, and B. A.

Google scholar has a known bug you should look out for when generating bibliography entries. If you published a paper and earlier had a published abstract with the same title, Google Scholar will assume that the abstract is the correct version. This paper was not published in Biophys. J!

The Munro (Chicago), Lenne and Rupprecht (Marseille) groups seek 2-3 postdoctoral fellows to join a newly funded (NSF/ANR) international collaboration on the multiscale dynamics of cell contact formation and remodeling.

Dear summer program: The website where I upload my letter of recommendation should NOT first require me to create an account with your organization. And it should DEFINITELY NOT ask me whether you may send additional promotional material my way. Regards, Any professor, ever

This is one of the finest pieces of popular science writing I have ever read--full of twists and turns and surprises. It takes us from van Leeuwenhoek's look at sperm to kids with heart defects, via Dr. No--take a moment and read it! 🧪

Congrats to my Hopkins colleague Danielle Speller for the Joseph A. Johnson award! (Hoping to get a sneak preview when her experiments discover axion dark matter.) ww2.aip.org/aip/2024-jos...

If you're interested in a PhD in biophysics (broadly defined), consider Johns Hopkins. Our Jenkins program (Dec 1 deadline) has folks working on CryoEM structures, computational modeling, single-molecule biophysics, and lots more! biophysics.jhu.edu/graduate/jen...

Our latest discovery of “lowest recorded temperature for eukaryotic cell motility” going all the way down to -15deg C. Come for the crazy cold Arctic & stay for diatoms. Will write longer thread - but enjoy video below of diatoms gliding on frozen ice surfaces. Congrats @zqing.bsky.social & team.
