... 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...

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.” 🙌 Learn more 👉 www.ccdc.cam.ac.uk/solutions/ab... #Crystallography #Pharma

The Royal Society film on Kathleen Lonsdale featuring footage from the @IUCr archive, was recently nominated for a Webby Award by the Academy of Digital Arts and Sciences. Voting is open until Thursday 16th April. see tinyurl.com/msddeem8

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.

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. Watch the short documentary here: youtube.com/watch?v=FNNI0R2gwM4

Congratulations!

I am incredibly honored to recieve this prize! Greatly looking forward to attending @iucr2026.bsky.social - I have many people to thank for all the learning and exciting research over these past years. First and foremost though, is my crystallography mentor and great friend @keninge.bsky.social

Gift article:

An article I have been waiting to read for years, by my friend (and #crystallography hero) Juanma Garcia-Ruiz and co-authors, has just been published! "On The Origin of our Fascination with Crystals" 💎 😌 www.frontiersin.org/journals/psy...

Hear hear, IUCr2029 @iucr2029.bsky.social is here! 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

❄️ Don't let your research stay frozen. 4 days left to submit your IUCr2026 abstract, no registration required, just hit submit. This is your final extension. Thaw out that draft and get it in before the window closes. 📅 Feb 22 at 11:59 PM ET 👉 event.fourwaves.com/...

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... #chemsky

The latest issue of the @IUCr Newsletter is now available at www.iucr.org/news/newslet... with lots of topics of interest in #crystallography.

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. #BraggYourPattern

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."

The deadline for abstracts is coming up on February 15, 2026. If you’re planning to present in Calgary, now is the time to prepare and submit your work. event.fourwaves.com/...

Lauren Hatcher uses time-resolved crystallography to understand how photoactive molecules change structure when exposed to light.

Great to see the work in Vitaly’s group on descriptors for comparing crystal structures get recognised, and in an interesting article to boot!

Duplicates of crystal structures are flooding databases, implicating repositories hosting organic, inorganic, and computer-generated crystals. The issue raises questions about curation practices at databases and claims around novelty. cen.acs.org/research-int... #chemsky 🧪
