... and before people get scared by the GitHub page: Fourier Tiler is a completely GUI based, user friendly program anyone can play with, and it does not require any installation 😉

Please have also a look at the manual, where I show examples of educational uses of it.

github.com/stecanossa/F...

And of course now anyone can flood Bluesky with their custom patterns... add the tag #FourierTiler so people don't miss any and can find them back! And of coruse, let's saturate #Braggyourpattern as well 😏

Time for a second casual #crystallography tip: peak tables in lattice viewers are not showing you the reciprocal space of the crystal, but just some intensity maxima!
If you think it's a detail, I have a section and a figure explaining why in my recent tutorial review: pubs.rsc.org/en/content/a...

Round robin on structure analysis from 3D electron diffraction data This blind test uses three known samples to determine the accuracy limits of 3D electron diffraction and to assess various challenges. The study aims to evaluate how well different users with diverse experimental setups can perform tasks such as hydrogen-atom detection, mixed occupancy analysis and absolute structure determination. By comparing results across multiple participants and platforms, we can gauge the reliability of the method and identify potential areas for improvement in 3D electron diffraction techniques.

A thought‑provoking industrial plenary at the #BCA2026 today from John Helliwell of @manchester.ac.uk.

Our standout moment was when he said, “We lead the world in FAIR data through the CCDC.” 🙌

Don’t forget also that fool May who triggered the rush to Brexit. Remember Brexit means Brexit and we are going to make a success of it

It was a measurable influence on me, arriving at university, to be taught in a building named after a woman scientist. Having women like Lonsdale to inspire me are a big reason I work in the area I do.

British chemist Dorothy Hodgkin in her laboratory in 1964. She is sitting at a wooden desk, wearing a blue cardigan and green skirt, resting her chin on her hand as she looks thoughtfully toward the camera. On the desk beside her sits a black and gold microscope and a glass display case containing a large, complex crystal structure model. To her left, bookshelves are packed with scientific texts, including a prominent red spine titled "Penicillin Crystal Structures." This image captures the Nobel Prize winner in the environment where she produced the world’s first 3D atomic maps of essential medicines like penicillin and insulin. The scene highlights her intense intellectual focus and the physical tools of her pioneering work in X-ray crystallography. Digital restoration and colorization by Seriously Scientific.

Remembering Dorothy Hodgkin on International Women's Day!

While Fleming found the mold, Hodgkin solved the 3D atomic puzzle of Penicillin.

Using X-ray crystallography, she mapped the molecule's structure, allowing it to be mass-produced and saving millions of lives! 🔬🗺️

#WomenInScience

We're celebrating #InternationalWomensDay by shining the spotlight on one of the most remarkable women of science, who also worked here at the Royal Institution: Kathleen Lonsdale.

A positive sign from the organizers of a very much awaited #crystallography congress that is getting closer and closer 🔥

Give it a nice 'Follow', fellow structural chemists 🤜✨🤛

I spy a Cryostream!

#crystallography is much more than biological research

Oh my word! I just logged in to check the abstracts I have to review and we have 25 submissions for the 'Engaging all in Crystallography' microsymposium @iucr2026.bsky.social

How wonderful that there are so many #crystallographers out there wanting to share the love of their craft!

Oh I love some respect for language, we're all guilty of some misuse, it's never too late to acknowledge and be patient and informative to others!

I could bring up "lattice", "Bragg reflections", and "n-dimensional" (n=0,1,2,3), but I already discuss it here: pubs.rsc.org/en/Content/A...

PERSON OF THE DAY. 10 February 1923. German-born Wilhelm Röntgen died (aged 77). He produced and detected electromagnetic radiation in a wavelength range known as X-rays which earned him the 1st Nobel Prize in Physics in 1901. It’s one of the greatest diagnostic medical advances of all time.

What did you do today? I added plane waves.

While on the topic of sexism and the Nobels, let us recall how the rightwing British newspapers reported Dorothy Crowfoot Hodgkin's 1964 prize.

Daily Telegraph: "£18,750 Award to Mother of Three"

Daily Mail: Hold my beer -

"Oxford Housewife Wins Nobel."
