Musings about science, biophysics, inference, and occasionally Bach and Shostakovich

The new 50% US tariffs imposed by the Trump administration affect ~ $20B imported from 🇨🇦, which translates to ~ 5.2% of U.S. goods imported from 🇨🇦 Straight out the academic handbook: not picking one’s battles and ruining one’s reputation over a 2.6% net change.

Help!!! We're working on a Bayesian approach for decoding MERFISH images in 3D, and we’re trying to identify an accessible MERFISH dataset that’s “truly volumetric” in the imaging sense. Even a pointer to the right paper, repository, or person to ask would be helpful. Thanks so much!

It’s been 30 yrs since Zwanzig’s “non-eq stat mech” As written, it has solidified the notion that theory develops models, and MD (perhaps) should be left to parametrize. Maybe it’s time to re-pitch the work using functional integrals & tie this formulation to likelihoods :)

Really interesting research showing that while ultra-specialization in a single discipline might lead to better results early in one’s career, multi-discipline training and practice pays off big time in the long run. This applies to a range of professions from scientists to athletes and more

Recent discoveries on the acquisition of the highest levels of human performance

Tracking has always been at the ❤️ of the scientific method, from planetary motion to single particles. Weiqing’s thesis intro on tracking was so beautiful we turned it into a perspective in JCP who then selected it as a #Scilight. Take a look! 😊 www.aip.org/scilights/tr...

Tracing fluorescence tracking’s past, present, and future

Artificial intelligence and parallel computing could refine studies of the movement of single molecules inside cells.

Can we learn motion models from post-processed tracks? 🧐 Not really 😢 Emission noise accounts for ~99% of the likelihood. TLDR: What you think is anomalous diffusion… might just be noise. 🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️ 🔗 Read more in our latest preprint: arxiv.org/abs/2507.05599 #Biophysics

How Easy Is It to Learn Motion Models from Widefield Fluorescence Single Particle Tracks?

Motion models (i.e., transition probability densities) are often deduced from fluorescence widefield tracking experiments by analyzing single-particle trajectories post-processed from data. This analy...
