The Congress organisers thank those who have submitted abstracts and appreciate the enthusiastic response from the global community. For those who need more time, the abstract submission portal will remain open until 21 February 2023.

With only hours left to submit an abstract, we encourage you to reach out to your colleagues, networks and community to upload abstract submissions that, in turn, will provide a comprehensive and exciting programme for our global crystallography and structural science colleagues.

The International Union of Crystallography turns a grand age of 75 in 2023 but whereas most 75-year-olds are happily retired, there is no rest planned for the IUCr.

After reviewing the nominations and candidates, the selection committee agreed to propose Professor Jian-Min Zuo (University of Illinois at Urbana-Champaign) as the recipient of the 2023 Gjønnes Medal for his outstanding contributions to the development and application of quantitative electron diffraction.

We announce with a heavy heart that former IUCr President Henk Schenk, Professor Emeritus at the University of Amsterdam, The Netherlands, died on 14 September 2023. Professor Schenk served on the IUCr Executive Committee [1993–2005 (President 1999–2002)], as Co-editor of Acta Cryst.
