The IUCr 2026 team wishes you a joyful holiday and a bright new year ahead! Thank you to our global crystallography community, we can't wait to welcome you to Calgary in 2026. #IUCr2026 #Calgary #tourismcalgary #crystallography

Happy Tibb's Eve, everyone! #birds #birdphotography #Ontario

📢 One less molecular mystery - the crystal structure of diacetylene is solved, published in @iucrj.iucr.org today! Fantastic work by Larissa, and also I think will be the first structure deposit in @ccdc.cam.ac.uk from wombat! Read the OA paper here journals.iucr.org/m/issues/202...

Happy Winter Solstice! Here are four birds from yesterday's chilly walk in a wilderness area! #Ontario #birds

And the molecule of the year for 2025 is...🥁... ...hexanitrogen! (I had a feeling this one would win 🤭) Thanks for voting, everyone! #chemsky cen.acs.org/synthesis/Mo...

Still another month or so to apply to work with me: predicting the crystals and their properties on Titan!

New paper out, High-pressure crystallisation of Isobutyronitrile pubs.acs.org/doi/10.1021/..., nice results from the UWA and Synchrotron team that show this small molecule crystallises into the same structure as at low temperatures. There's some lovely calculations that explain why this may be.

arXiv will no longer accept review articles and position papers unless they have been accepted at a journal or a conference and complete successful peer review. This is due to being overwhelmed by a hundreds of AI generated papers a month. Yet another open submission process killed by LLMs.
