EM Summer of Code! · hyperspy hyperspy · Discussion #3518
The idea of trying to make a fun competition out of coding faster data processing solutions got me thinking, maybe hyperspy should post coding challenges each month and see what solutions people co...

I had a great time at the @diamondlightsource.bsky.social Hyperspy 2025 workshop.
Kind of want to keep it going, how do people feel about EM summer of code challenges? 🤔

#cryoEM 🧪⚛️ Lena’s paper on imaging thick biological sections with STEM is finally published! We started this work almost 10 years ago. After Lena passed in 2023, I spent much of my sabbatical working with Yue and Steve to wrap this up. Also learned a lot about TEM vs STEM dose efficiency
Tilt-corrected bright-field scanning transmission electron microscopy (tcBF-STEM) offers enhanced contrast and dose efficiency for cryo-EM in thick biological specimens.

Dose-efficient cryo-electron microscopy for thick samples using tilt- corrected scanning transmission electron microscopy - Nature Methods
Tilt-corrected bright-field scanning transmission electron microscopy offers enhanced cryogenic electron microscopy contrast and substantial improvement in dose efficiency for thick samples such as bacterial cells and large organelles, while still being able to perform single-particle analysis.

What if you just keep zooming in?

A new version of pyxem (0.20.0) is now available on pypi and conda-forge. Hopefully 🤞 this is the last release before a 1.0.0 release, which has been a very, very, very long time coming. #4DSTEM #HyperSpy github.com/pyxem/pyxem/...
Release v0.20.0 · pyxem/pyxem
(Finally) this release explicitly supports numpy 2.0.0. This means that we also have to drop support for pyfai. From a development side this is a really nice dependancy to remove and hopefully th...
