We are sad to pass on the news that Uri Shmueli, Professor Emeritus at Tel Aviv University, Israel, died on 15 February 2023. An excellent scientist, Professor Shmueli had a long-standing association with the IUCr as Editor of International Tables Volume B: Reciprocal space.

We send hearty congratulations to Wayne A. Hendrickson (Columbia University, NY, USA), winner of the 13th Ewald Prize for his exceptional contribution to structural biology including the development of MAD/SAD methods and crystallographic theory. Professor Hendrickson will deliver the Ewald Prize Lecture during the Opening Ceremony of the 26th IUCr Congress on 22 August 2023.

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.
