When the Microscopy Society of America set out to launch Elemental Microscopy, we partnered with them to make it happen fast - an interactive, open-access journal where readers can explore data and code while MSA maintains full control of the publishing process.

Our new DGP ptychography methods paper is online on the arxiv! arxiv.org/abs/2511.07795

Code + tutorial notebooks available if you want to try it out for your own ptychography experiments.

We've just posted an open faculty search in MSE at Stanford! facultypositions.stanford.edu/en-us/job/49...

In this paper, we show that neutral gallium clusters from a Ga-FIB microscope’s liquid metal ion source can create nanopores in thin samples and damage. Because these clusters aren’t stopped by the beam blanker, your samples could be exposed to them without your knowledge!

Workshop on the Applications of 4D-STEM The purpose of this workshop is to highlight the applications of 4D-STEM across a broad range of materials classes, both hard and soft, and by demonstrating the micro- and nano-structural information ...

Hello! Who's up for some more 4D-STEM?

Maybe a 2-day workshop on applications of 4D-STEM in sunny Yorkshire is just your jam? Hop over to the @royalmicrosoc.bsky.social for info, www.rms.org.uk/rms-event-ca...

We look forwards to seeing you there with

Evaluating the Transfer of Information in Phase Retrieval STEM Techniques - Elemental Microscopy Evaluating the transfer of information in various phase retrieval STEM techniques using analytical and numerical methods.

Excited to share this interactive pre-print investigating the information transfer of phase retrieval techniques in STEM 🔬

Now everyone has an open-access tool to optimise their experimental parameters ✨

Feel free to share and play around with it 🧪

www.elementalmicroscopy.com/articles/EM0...

Super proud of this work, which showcases modern scientific publishing for open science 🧪

Inspired by the insights of the interactive CTF widgets, we propose a novel phase-retrieval algorithm which achieves robust information transfer on sub-sampled datasets 🙌

@materials-mrs.bsky.social great job with the badge pickup guys - I think there are only 1000+ people ahead of me in line. And I tried to pick it up last night and was turned away.

Alright I'm in Seattle if anyone wants to grab dinner!

China Just Turned Off U.S. Supplies Of Minerals Critical For Defense & Cleantech - CleanTechnica In response to new Trump tariffs, China cut dysprosium, terbium, and tungsten exports—hitting U.S. EVs, wind, and military systems hard.

What a completely unpredictable turn of events!!

Strain release by 3D atomic misfit in fivefold twinned icosahedral nanoparticles with amorphization and dislocations - Nature Communications The crystallographically forbidden fivefold symmetry in icosahedra remains a long-standing mystery. Here, the authors resolve the three-dimensional atomic structure of Janus-like icosahedral nanoparti...

How a Canadian scientist and a venomous lizard helped pave the way for Ozempic - National | Globalnews.ca In 1984, Dr. Daniel Drucker, an endocrinologist from the University of Toronto, discovered a hormone that helped pave the way for popular diabetes drugs such as Ozempic.

This is the most relevant article to NIH and research cuts I’ve seen.

Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !”

YouTube video by Veritasium What if you just keep zooming in?

Very cool explainer video on my field of electron microscopy! I still remember the first times I just kept zooming in and zooming in... and seeing atoms.

Hey there 🦋🧪, we're a new open access microscopy journal and wanted to introduce ourselves! EM aims to modernize scientific publishing for microscopy, by prioritizing open science, transparency, and accessibility and using open-source formats and interactive notebooks 🙌

@curvenote.com @mystmd.org 🚀

It would take a looong time for this to work - network effects are very powerful in science!

Nanobeam phase mapping from simulated data (so we know the ground truth) - it's a great day for open source!!
