FEBS Letters

Cryo-electron microscopy (cryo-EM) revolutionized structural biology by enabling high-resolution imaging of biomolecules in their native state. This free special issue edited by Panagiotis L. Kastritis features 8 review articles that highlight how cryo-EM is moving beyond static structure determination toward understanding the dynamics, assembly, regulation, evolution, and cellular context of biomolecular complexes, increasingly supported by advanced computational and AI-driven methods.

FEBS Letters is pleased to announce we will be hosting a free webinar on circadian rhythms to be held on Thursday 25th June 2026 at 18:00 CEST. The webinar will be hosted by Carrie Partch and Emery Usher (University of California Santa Cruz, Howard Hughes Medical Institute), and will feature three short talks by experts in the field. This webinar is being organised to accompany our latest special issue on “Circadian clocks”, guest edited by Carrie Partch.

Circadian rhythms coordinate biological timekeeping on a ~ 24-h timescale, aligning physiology and behavior with the daily solar cycle on Earth. This free special issue edited by Carrie Partch features 14 review articles focusing on the latest advances in our understanding of the molecular basis of circadian rhythms, their pervasive and powerful control of biology, and new frontiers in the field, including approaches to modulate biological timekeeping to improve human health.
