Thanks to everyone who stopped by during #mmc2025! We had a fantastic time connecting with researchers, learning about exciting work in microscopy and sharing what the IUCr biology journals have to offer. ICYMI journals.iucr.org #Microscopy #StructuralScience #IUCrJournals

For early-career crystallographers, the IUCr awards the Struchkov Prize (iucr.org/iucr/struchkov…) every three years for outstanding achievements in small-molecule X-ray diffraction methods in chemistry, crystal chemistry, or materials science. Applications are now open.

Vitamin B12 structure determination by Dorothy Hodgkin was a tour de force. It's mind-boggling to imagine that such a complex exquisite molecular structure was solved at the atomic resolution 70 years ago in 1955. It was such a quantum leap in structural chemistry and biology.

A few years later, two of the greatest organic chemists in the world: Woodward from Harvard University and Eschenmoser from ETH Zurich achieved what is often regarded as the “Everest of organic synthesis”:-the total synthesis of Vitamin B₁₂. A 12 year effort with nearly 100 postdocs.

I'll be attending the European Crystallographic Meeting (ECM2025) in Poznan, Poland next week. Please stop by the IUCr booth if you would like to chat about publishing your work related to structural science, crystal engineering, and materials in Acta Cryst B!

In 1982, the physicist Dan Shechtman (left) accidentally discovered quasicrystals. By the time he won the 2011 Nobel Prize in Chemistry for his discovery, hundreds of scientists were trying to explain these impossible-seeming structures. quantamagazine.org/quasicrystals-…

IUCr conference (IUCr2026) is less than a year away. And yes (after 40 years) I can officially wear a cowboy hat and boots.

From the star-like glow of asterism and the shifting hues of color change and tenebrescence, to the shimmering chatoyancy and glowing fluorescence, each effect is rooted in crystal structure, light behavior, and mineral inclusions. geologyin.com/2024/06/gemsto…
