Lauren Hatcher discusses her work developing techniques for time-resolved crystallography

Researchers call for retraction of two recent <i>Nature</i> studies about AI-generated crystals

This study establishes a mathematical framework connecting symmetry operations with metrical restrictions through systematic analysis of symmetry operation representation matrices.

We share our pedagogical vision for a graduate-level small-mol­ecule chemical crystallography in-class exercises and list our preferred textbooks, computer programs, and websites.

A paper-based virtual X-ray diffraction experiment, which is based on the right-angle condition for constructive inter­ference, allows the implications of Bragg's law to be studies in a simple way.

Powder diffraction is a widespread technique found in academic, forensic, industrial research and quality-control laboratories the world over. The recent article by Kabova et al. [(2025), Acta Cryst. C81, 559–569] provides step-by-step guidance on how to proceed and the software the authors use, from sample preparation and the powder diffraction measurement itself, to the verification of the final structure.

We describe an efficient algorithm to compute the bridge length estimating the size of a complete isoset invariant, which classifies all periodic point sets under Euclidean motion.
