Want to simulate large nonconfluent tissues? Try the finite Voronoi model! 1) @wwang721.bsky.social and I show past implementations need a correction to avoid issues, and 2) we provide a new fast code that we'd like people to try! Preprint: arxiv.org/abs/2604.15481 code: github.com/wwang721/pyafv

Wei Wang, Brian A. Camley: Divergence of detachment forces in the finite Voronoi model https://arxiv.org/abs/2604.15481 https://arxiv.org/pdf/2604.15481 https://arxiv.org/html/2604.15481
for _ in tqdm.tqdm(range(1000), desc="Active dynamics"): diag = sim.build() forces = diag["forces"] active_velocity = v0 * np.column_stack((np.cos(theta), np.sin(theta))) pts += (mu * forces + active_velocity) * dt # Gaussian white noise theta += np.sqrt(2 * Dr * dt) * np.random.randn(N) sim.update_positions(pts)
PS Wei has put in a ton of work to make the code easy to install - it's just "pip install pyafv" and it's basically just as simple to run a AFV model as it is to simulate a bunch of random walks:

New paper out in @physreve.bsky.social (Editors’ Suggestion) with @diffusiveblob.bsky.social.

IMPACT OF PARENTHOOD ON UNIVERSITY EMPLOYMENT. Line graph shows how the probability of holding a research position changes from four years before to seven years after having children.
Becoming a parent is much more detrimental to women’s academic careers than it is to men’s

The Biophysics department at Johns Hopkins is hiring off-cycle *at all levels*! Take a look: biophysics.jhu.edu/2026/03/27/f... - we will start looking April 13. This is a great department to work in, in the middle of an expansion - please let me know if you have questions.
Since #durotaxis was described >25 years ago, most studies report cells migrating from soft → stiff
New work from my team at @ub.edu (in collaboration with D. Odde's lab) suggests we may have been missing the point all along...

An active material that's trying to contract can be guided by changing its friction with the environment. We predict some interesting examples, including patterns that can drive circular or linear motion of clumps of material. Work with Miller Fellow Cody Schimming: arxiv.org/abs/2603.03232

Derivation of the Green's function for an oscillator from Srednicki's QFT textbook, https://web.physics.ucsb.edu/~mark/ms-qft-DRAFT.pdf - discussion from Eq. 7.12 to 7.14 in that PDF
It's honestly been quite a while since I used the residue theorem! I think most of the applications in physics are in field theories? Here's something from Srednicki's QFT book:
Seconded. If anything, it has never been a better time to be a biophysicist, a complex system physicists, etc…. And it is a bit sad that much of it now happens *outside* of physics departments (for good and bad reasons…)
Are you a junior scientist working in theoretical biophysics? @zamakany.bsky.social and I are organizing another workshop this fall here at @hhmijanelia.bsky.social. Travel and the workshop expenses are all covered!

Check out this story! Atlantic writer Alexandra Petri visited my lab and played with some fruit flies and human organoids as she wrote about experiencing things that were affected by government cuts.

Thrilled that the lab's first @hhmijanelia.bsky.social project is up on bioRxiv! Story behind the story to follow. www.biorxiv.org/content/10.6...
This is actually a pretty big deal - it gives people whose eligibility to renew is expiring a shot at submitting with the additional data and productivity of the last half year. It would be better if NIH delayed the deadline but I know a bunch of PIs who are now slightly less screwed by the shutdown
She let me know that they recently received guidance that, ONLY for the January EI deadline (1/27/2026) and the February ESI deadline (2/3/2026), PIs can submit MIRAs even if their previous application (R35, R01, R15, R21, and R37) is still considered under review.
The path to this paper has so many stories.
Today I want to tell one about the value of saying so when you don't have the answer - and of the importance of community.
Fishing email saying that a student has filed a report for my class
This fishing email *almost* got me….its that time of year when semester is almost over and weird stuff happens and tired profs are almost the perfect targets here

Recognizing bad mentors: "One problem student is a concern. Two problem students is a trend. Three problem students is an established pattern." But this is also why evaluating mentorship is hard. Faculty are tenured with small-n student count - and sometimes the victims won't show up in that count
Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

screenshot of nature's search feature that shows you can only enter "start page / article no."
Is there an easy way to actually find an article for Nature Communications without a title if you know its article number? Nature's search has the same problem - if you look for article 1, you find all the other articles: www.nature.com/search/advan...
Is your paper article #1 in a volume in Nature Communications? Then in some records you may be getting all the citations for all the other articles - because exported citations can default to "starting page" (always 1) instead of "article number"

Marge Simpson, holding a CG membrane simulation snapshot: "I just think they're neat!"
"Why do you like membrane bending simulations so much?"
Ten years ago, I saw a paper with some data that has bothered me ever since: B cells in a 0-100 ng/mL gradient of CCL19 are attracted to CCL19, but B cells in 0-500 ng/mL are repelled (see movie, ignoring the big clusters for now!). Why? Here's our model! doi.org/10.1101/2025...
