How do proteins find their way to the cell's leading edge? @jimgalbraith27.bsky.social & @cathygalbraith.bsky.social break down how bleach line, FLOP, single-particle tracking, FCS & iPALM reveal intracellular fluid flow and an actin-myosin compartment barrier. doi.org/10.1038/s414...
Thank you for such a clear definition!
New post: What is the impact of AI on productivity?
I review all of the studies and data that I can find and try to provide a synthesis.
A disagreement emerges: micro studies find positive benefits but these benefits are yet to show up in the macro data.

wikipedia turns 25 today! the last unenshittified major website! backbone of online info! triumph of humanity! powered by urge of unpaid randos to correct each other! somehow mostly reliable! "good thing wikipedia works in practice, because it sure doesn't work in theory" - old wiki adage
We've got ISSUES. Literally.
We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do?

The image on the cover shows two sugars from the same cell-surface glycan separated by 9 Å, visualized with RESI (resolution enhancement by sequential imaging) enabled by metabolic labelling with DNA barcodes. IMAGE: Luciano A. Masullo, Max Planck Institute of Biochemistry, Germany. COVER DESIGN: Vanitha Selvarajan Original paper: Masullo, L.A., et al. Ångström-resolution imaging of cell-surface glycans. Nat. Nanotechnol. 20, 1457–1463 (2025). https://doi.org/10.1038/s41565-025-01966-5 Abstract: Glycobiology is rooted in the study of monosaccharides, ångström-sized molecules that are the building blocks of glycosylation. Glycosylated biomolecules form the glycocalyx, a dense coat encasing every human cell with central relevance—among others—in immunology, oncology and virology. To understand glycosylation function, visualizing its molecular structure is fundamental. However, the ability to visualize the molecular architecture of the glycocalyx has remained challenging. Techniques such as mass spectrometry, electron microscopy and fluorescence microscopy lack the necessary cellular context, specificity and resolution. Here we combine resolution enhancement by sequential imaging with metabolic labelling, enabling the visualization of individual sugars within glycans on the cell surface, thus obtaining images of the glycocalyx with a spatial resolution down to 9 Å in an optical microscope.

Manim (www.manim.community) is such a neat tool for generating videos that describe microscopy theory. It’s possible to animate a fluorophore behaving as a Lorentzian with a single line of code—amazing! Code (I’m so sorry about the variable names) here: github.com/zacsimile/ra...
The rarest of sights - a big glossy journal publishing negative replications! Yes, we had to bundle 4 replications into one article AND we had to wait 2 (!!) years in peer review, but here we are:

Doing a PhD is - at heart - one long discussion with your mentor. The discussion changes over time - with unexpected turns and ups & downs - but through it all is a pair of people discussing a topic endlessly to make sense of it.
PhD students: choose someone you like to talk to!
Toegeven dat de kwaliteit achteruit gaat is iets waarvoor bestuurders allergisch zijn. Zelfs het online onderwijs tijdens corona werd destijds minstens zo goed gevonden als wat we in de collegezalen en laboratoria doen…

The “canonical” story how Rosalind Franklin got wronged by Watson and Crick inadvertently makes her look far less scientifically competent than she was (“She did not realize the significance of her own data!”). This article offers a much more nuanced account of what happened.
Coherence in optics is a really tricky topic for people. I feel like the language around it could be better/cleaner

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! 😊

New review on experimental datasets that can be used to benchmark protein force fields. And if that doesn’t tickle your fancy, the data can also be used to benchmark machine learning models for biomolecular structure and dynamics.

Check out this community comment in Nature Communications on biomolecular condensates! 🧪🔬 💧
The piece shows how condensates fundamentally change the study of biology, offering insights into cellular processes.
A great resource for anyone in the field, especially newcomers.
