We are deeply saddened to share the news of the passing of George Michael Sheldrick, a prominent figure in crystallography whose contributions have shaped the field for decades. A full obituary will be published in Acta Crystallographica A in due course.

Curiosity and diffractometer: What is this yellow stuff that fell everywhere recently after wave of hot weather from Sahara? Results: Breaking news! Sahara contains sand! More precisely, mostly quartz, a bit of calcite, dolomite and mica. #crystallography
