This special issue advances understanding of recent northeastern Japan earthquakes, including the December 2025 Mw7.6 off Aomori and November Mw6.8 off Sanriku events. In the post‑2011 era, we examine spatiotemporal plate‑interface evolution amid postseismic deformation of the M9 Tohoku‑oki earthquake and coupled seismic–aseismic slip. Multidisciplinary studies span event analyses to broader subduction‑zone seismotectonics, clarifying diverse slip behaviors.

This Collection welcomes original research that advances our understanding of malnutrition, including studies on screening and nutritional assessment methods, mechanistic insights, and approaches to improve clinical and public health outcomes.

BMC Pulmonary Medicine is calling for submissions to our Collection which aims to explore the intricate relationships between social and economic factors and pulmonary diseases. We invite researchers to submit studies that address how socioeconomic status, environmental conditions, and healthcare disparities influence the prevalence and management of pulmonary disorders, particularly in vulnerable and low-income populations.

This Collection aims to bring together research on how animals produce, perceive and use colour throughout their lives. We welcome studies on the mechanisms behind colour and pattern formation, rapid and reversible colour change, visual ecology, and the functional roles of colour. Work on large‑scale evolutionary patterns and the impacts of environmental change on colour production and colour-mediated behaviours is also encouraged.

BMC Medical Education welcomes submissions to our Collection, Gamification and virtual reality in medical education and healthcare professions - Part II. This Collection seeks to identify pivotal principles underlying the effective use of these technologies.

BMC Medicine is calling for submissions to our new Collection on ultra-processed foods, focusing on their health implications, mechanisms of action, and policy implications. We welcome submissions that explore the intersections of nutrition, food policy, and health outcomes related to ultra-processed food consumption, aiming to inform effective strategies for improving public health and dietary practices.
