This Collection marks 20 years of Implementation Science by inviting papers that critically analyze the evolution of the field and propose how this shapes its future. We welcome bibliometric and citation analyses, content analyses of the literature, and studies of geographic, disciplinary, authorship, or funding patterns — all grounded in critical interpretation and forward-looking insight.

This Collection will highlight emerging technologies that advance the diagnosis, monitoring, prediction, and treatment of critically ill patients. We welcome original investigations, reviews, perspectives, translational studies, and proof-of-concept reports spanning engineering, clinical medicine, computational science, and biotechnology.

Living Food Heritage explores local foods as living systems shaped by culture, ecology, and time. Honoring the late Dauro Mattia Zocchi, the collection brings ethnobiological perspectives on how communities negotiate identity, authenticity, and sustainability through food, highlighting cross-cultural dynamics, temporal change, and applied pathways that support livelihoods, cultural resilience, and sustainable futures.

Efficient resource use in healthcare depends on strong economic evaluation methods that clarify trade‑offs and guide smarter allocation decisions. This Collection highlights emerging analytical tools and frameworks that advance this work and invites research that pushes the field forward.

This Collection addresses a central challenge in implementation science: the proliferation of frameworks without sufficient guidance on their use, update, or integration. We invite empirical papers, methodological contributions, and theoretically grounded work that revisits, extends, synthesizes, or challenges existing frameworks — particularly in light of emerging global health priorities and the need for greater equity and cross-setting applicability.

Epilepsy is frequently accompanied by comorbidities — including psychiatric disorders, sleep disturbances, cognitive impairment, and immune-related conditions — that significantly affect patient outcomes. This Collection welcomes experimental, translational, and clinical research on the mechanisms, assessment, and management of epilepsy comorbidities across the lifespan, including developmental comorbidities in children, precision medication strategies, and neuromodulation approaches.

BMC Molecular and Cell Biology welcomes submissions to our Collection on Ubiquitination and the proteasome. This Collection seeks to showcase research that explores the complexities of ubiquitin-mediated proteasomal degradation as well as other roles of ubiquitin in cell signaling and regulating cellular processes. By bringing together current research, the Collection aims to support continued progress in understanding the ubiquitin-proteasome system and its broad biological significance.

This research collection aims to highlight integrative and mechanistic studies at the interface of ocular and central nervous system health. We invite submissions focusing on shared neuroinflammatory processes, vascular dysfunction, glial activation, and neurovascular coupling between the eye and the brain. Emphasis is placed on diagnostic innovation, biomarker discovery, and translational approaches.

This Collection seeks to deepen our understanding of age-related macular degeneration and retinal pigment epithelium dysfunction, focusing on translational research and therapeutic targets.

This Scientific Reports Collection highlights developments in NV‑centre generation, characterisation, and integration, as well as their emerging applications in precision measurements and quantum technologies.

This Collection invites researchers to submit their work on alcohol harm reduction in low- and middle-income countries (LMICs). We seek contributions that address evidence, policy, and practical interventions aimed at mitigating alcohol-related harm. By showcasing diverse research perspectives, we aim to enhance understanding and implementation of effective alcohol policies and practices.

This Collection invites researchers to submit their findings on the development and application of value-based care models across varied health systems. This Collection will highlight research that addresses barriers, assesses impacts on patient outcomes, and explores the integration of technology in value-based care. By fostering dialogue and sharing insights, this Collection aims to contribute to improved healthcare delivery and equity for all populations.

This Collection underscores the urgent challenges in mathematics education, including inequities, low achievement, and insufficient teacher preparation, all intensified by digitalisation and shifting labour demands. It emphasizes the need for curated resources that unify global research on curriculum design, instructional innovation, technology integration, and student motivation to support educators, researchers, and policymakers.

This Collection explores the role of blended finance in bridging climate and sustainability financing gaps, focusing on instrument design, risk-sharing mechanisms, and impact measurement. It invites interdisciplinary research on financial innovation, ESG integration, and institutional frameworks that mobilize private capital for renewable energy, agriculture, and rural development in emerging and developing economies.

Curiosity drives information seeking in humans and animals beyond reward. This collection explores its mechanisms, neural basis, and evolution.

The Collection seeks to advance new models of innovation that are both effective but also ethically grounded. It invites contributions that explore how ethical frameworks can shape decision- making, curriculum design, assessment practices, and the professional identity of teachers and ethical leaders.

This topic addresses AI-era threats to digital trust, focusing on deepfake generation, identity fraud, and synthetic media manipulation. It emphasizes advanced detection techniques, content authentication, and proactive defense strategies to safeguard digital interactions, protect identities, and maintain trust in online platforms.
