🧬 Molecular mirror images take the spotlight! The 2026 #Chemistry #Nobel honors Henri B. Kagan and Kenso Soai for discoveries in molecular handedness—a powerful reminder of why 3D structure matters to #crystallography, #medicine and life. Read more on the ACA blog: bit.ly/4j4CcKD

It is worth knowing that a similar photo of DNA was taken about a year earlier by Elwyn Beighton working in the group of Bill Astbury. seehttps://digital.sciencehistory.org/works/zys80b4

In the 1950s, Lipscomb & colleagues unpicked the structures of several boranes using low-temperature x-ray crystallography, determining they shared two electrons across three atoms. This accounted for boranes’ unusual geometry & unexpected dipole moment. www.chemistryworld.com/news/fifty-y...

As many of you know I have often written about misuse of crystallographic terminology in the literature. Probably the most prevalent failure is in distinguishing between lattice and structure. But it gets worse: see doi.org/10.1107/S205.... Enjoy!

For those interested in cryocrystallography I have written an article for the @IUCr newsletter on the history of the Cryostream. See www.iucr.org/news/newslet....

The @crystallography.org.uk Chemical Crystallography Group Autumn Meeting is being held online on October 27th, registration is open. The theme is Crystallography Under Non-Ambient Conditions. Abstracts for presentation welcome, including from Early Stage Crystallographers. @escg-bca.bsky.social

If you're at an early career stage, working in crystallography, you may be interested in the ECA's Women in Crystallography grants (ecanews.org/financial-su...), for meeting attendance. Current applications close September 30th. @crystallography.org.uk @escg-bca.bsky.social @yc-dgk.bsky.social

@cryst-rev.bsky.social Several new book reviews in Crystallography Reviews www.tandfonline.com/action/showA... spanning primary school science education, maths for biosciences, powder diffraction and molecular drug discovery.

A new type of article for Acta F: Protocols The purpose of this new category is to provide to the reader procedures that are sufficiently detailed so other researchers can reproduce the described workflow. Find out more in 'Show me how it's done: introducing Protocols': doi.org/10.1107/S205...

We're celebrating 20 years of Acta Crystallographica Section F!🎉🥳 Join us by contributing to our celebratory collection of articles, which is now open for submissions! Find out more at journals.iucr.org/special_issu...

Poster Judges Needed for IUCr 2026! We're still looking for volunteers to judge poster presentations at IUCr 2026. If you're a senior PhD student or above and your own poster is not being judged, we'd greatly appreciate your support. Sign up by July 31: forms.gle/uZNrws4VyB...
