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.

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...

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.

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."

Crystallographic workshops – a primer and perspective from Whitworth University's Summer Crystallography Institute Whitworth University's recent Summer Crystallography Institutes offer important insights into training and engaging the next generation of structural scientists in a workshop setting.

That's a right-handed helix!

Structural chirality and natural optical activity across the α to β phase transition in SiO2 and AlPO4 from first principles First-principles calculations on SiO2 and AlPO4 show that phase transitions reversing space-group chirality do not change the sign of optical rotation, clarifying the microscopic origin of this phenomenon.

Shedding light on how photoactive crystals respond in real time Lauren Hatcher discusses her work developing techniques for time-resolved crystallography

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!

The duplicates that haunt crystallography databases Researchers call for retraction of two recent <i>Nature</i> studies about AI-generated crystals

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 🧪
