My mom is so goddamn impressive. Grew up literally dirt poor. First woman to major in Engineering at the University of Colorado. Story I always heard was that she was an art major and one of her girlfriends dared her to take an engineering class, and she did it out of orneriness. Talk about (1/3)

NSF Update Funding curve overall. A little bit of progress in the past week, but only a little bit. Now by Directorate... 1/11

I have now figured out how to make this in R with ggplot2. I feel very proud.

Tongariro Alpine Crossing. All the students made it in under 10 hours. Absolutely amazing.

Hey #Physics / #ITeachPhysics / #Biophysics / #Math friends: a math colleague has a student who took complex analysis last semester and who wants to practice using the residue theorem to compute *real things* instead of random toy problems. Do you have good examples? Surprisingly, I don't ...

I grew up with the In Living Color alt halftime show but ... dissertations are going to be written about NFL halftime shows now, right? 😻😻😻

Big news time! After 15 wonderful years at Earlham, I'll be starting in July in the Smith College physics department!

Well this looks really interesting

My favorite kind of sale. The 3rd bottle costs more than the first two.

Who doesn’t love a good diffusion paper

It's letter of recommendation season, but ... my goodness, do notes like this make it worth it!

Here is a solid, thought-provoking post.

Lunchtime tart for the wife’s birthday! Quite pleased with how it came out.

Definitely wanted this to lead to some biophysical version of the Coriolis force.

I am honored and excited to present our recent work on mixed AND asymmetric membranes at @bppbseminar.bsky.social! 🧪 My online talk will be this Friday, 11/21/25, 11am US Eastern time. Many thanks to the organizers for putting this together! More details here: sites.google.com/view/bppb-se...

I love having students work in groups to write sample exam problems in class. This time, I told them to take some existing problems and make them harder. It’s so cool seeing them dive into things like “well, we could give less information … what could we leave out?” #ITeachPhysics

I know this is not the question. But do we know the mechanism yet?

It's angular momentum day in my #Physics class, so of course we start with fidget spinners on their desks and Emmy Noether on the screen as they walk into the room :)

Did you just give a #Physics exam where every problem had 67 either in the question, or as the answer? Because I just did.

Wait, wut?

why would you do this

I asked what turned out to be a really hard question in my intro class. Build this circuit on a breadboard (easy). Measure the equivalent resistance of the two parallel resistors (easy). Measure I1, the current through R1 (whoa!). #ITeachPhysics a lot, and I was surprised by just how tough this was.

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

This may well be the most fascinating job post I've ever seen! A whole (short) thread worth reading, and getting excited about. Whether or not you're a relevant candidate.

Major cool membrane conference coming up next week! The Biomembrane Days 2025, organized by an amazing team from the MPI for Colloids and Interface Science @mpici.bsky.social: Rumy Dimova (@dimovalab.bsky.social), Helge Ewers, and Thomas Weikl. I'm so very much looking forward to attending! 🤩 🧪

Old notes

Yet again, someone’s off leash dog attacked mine on a walk. Of course it had to be something as muscular as a pitt bull. Everyone’s fine. But I’m getting too old to throw my boat in the middle of dog fights.

I love this question for intro physics

Slightly late to this, but I’m watching the Fast and Furious movies for the first time. I’m on #3. The series seems to think we’re watching for Paul Walker. Are they serious?!

Tour de force on the kinetics and mechansms of lipid transport in cells through exquisite use of bifunctional probes by @nadlerlab.bsky.social and colleagues. Such an exciting time for the field. www.nature.com/articles/s41...

We are hiring into 3 (THREE!) tenure track lines this year at Wake Forest — if you’re looking please reach out, I love chatting about our department! We are a vibrant group that love & embrace the teacher-scholar model 👩‍🏫

Found an old box of tapes. Now listening to the Soup Dragons.

Can’t wait to introduce bird-based storage into my backup system

A friend has pointed out that “stare at it and be smart” is a very generally applicable method

Middle-aged folks: how did you learn to factor polynomials like ax^2 + bx + c? My kids have learned the diamond and box methods. I'm pretty sure I just learned "stare it and be smart."

Does protein dimerization always help targeting and dwell time on DNA? Not for a population! Dwell time is especially sensitive to spacing between DNA targets. Nonspecific binding and facilitated (1D) diffusion also play a key role. Super proud of Mankun Sang’s work! doi.org/10.1101/2025...

🖥️🧬I have a tool/lib that I want to make that I think will be useful. But, all of my students are busy with projects. While I have a plan & cycles to help, it will take way longer if I do it all myself. It needs to be written in Rust & be fast. If you’re interested in learning more, please ping me!

Amazing

The Banach-Barkski Pair-of-dogs

This is a very big scientific milestone: stem cells appear to have permanently cured most diabetics in this small but historic trial based on the work of Harvard researcher Doug Melton, who has 2 kids with diabetes. www.nytimes.com/2025/06/20/h...

Very smart, high ROI initiative from the Spencer Foundation. Providing bridge funding for canceled NSF grants: 1) directs funds to projects already screened by a top-noch review process. 2) avoids imposing proposal prep costs on researchers. 3) ameliorates the disruption from GOP sabotage.

Timeless. My Science and Pseudoscience 1st year seminar students loved it this past year!

I spent a year as a Corps member. Literally one of the best things I’ve ever done. ❤️❤️😅

Are you looking for a faculty job? We are hiring in my department at Roswell Park NOW. Contact me for details as I await the formal ad. (Please RT.)

This is well done

Can sensing of membrane receptors be switched on at tunable threshold densities, without active processing? Proud to share this preprint led by the awesome Dr Foley, please check it out!

I’m excited to finally share our new preprint! Membrane-associated assembly processes like CME function as precisely-tunable, spatially targetable, robust on/off switches that don’t require energy at decision-time. arxiv.org/abs/2505.17290 🧪

NSF Physics was cut by 85%, basically wiping out most of its capacity for supporting research. NSF Astronomy was cut by 53% Undergrad education was cut by 71% and research on learning by 79% Graduate education was cut by 100% to ZERO. #GiftLink ⚛️🔭 www.nytimes.com/interactive/...
