This Collection aims to highlight cutting-edge research and reviews on cell and gene therapy, with a focus on bridging fundamental biological mechanisms—such as gene regulation, cell plasticity, and immune modulation—with translational and clinical applications. The goal is to provide a comprehensive resource for researchers and clinicians, addressing both the promises and challenges of these rapidly evolving fields.

In this special collection, we welcome contributions proposing theory, methods, and applications that help address challenges arising in areas such as health, mobility, education, politics, and related societal domains. The aim is to provide rigorous evidence of how network science can enhance our understanding of complex social systems and improve human well-being at both individual and collective levels.

This Collection aims to highlight high-quality and innovative contributions presented at CBCFD, showcasing recent advances in numerical methods, turbulence modeling, high-performance computing, multiphysics simulations, data-driven approaches, and industrial CFD applications.

This collection highlights innovative research on quality assurance in radiopharmaceuticals, focusing on safety, validation, and regulatory compliance. We welcome studies on analytical methods, cGMP practices, and emerging technologies in nuclear medicine. The goal is to advance standardized protocols and improve patient outcomes through reliable radiopharmaceutical production.

Advances in molecular pathology and evolving WHO classifications have improved disease stratification but created new diagnostic grey zones. This Collection examines challenges in integrating morphologic, immunophenotypic, and molecular findings, particularly in cytology and small biopsies where tissue is limited. It focuses on classification dilemmas, diagnostic uncertainty, molecularly defined entities, specimen triage, reproducibility, and preoperative risk stratification.

This Collection focuses on childhood and adolescent obesity as an escalating public health crisis driven by sedentary lifestyles and poor diet, emphasizing the role of oxidative stress in the development of cardiometabolic disturbances that increase the early risk of type 2 diabetes, cardiovascular disease, and related metabolic complications.

This collection aims to capture circumpolar Arctic biogeochemistry under changing climatic conditions. We welcome a wide range of manuscripts with a focus on isotopic, biomarker, micro and molecular fossil, and genomic data including eDNA, aDNA, and sedaDNA. We particularly encourage multi-disciplinary research that incorporates diverse data types, analytical approaches, and collaborations.

AI and digital health technologies are transforming knee surgery, from diagnosis and planning to intraoperative guidance, rehabilitation, and outcome prediction. This Collection explores how AI, machine learning, robotics, and digital tools support personalized care across the clinical pathway. Topics include individualized alignment targets, predictive models, complication forecasting, AI-assisted rehabilitation, patient-specific planning, implant selection, and wearable monitoring.

This collection examines how political and legal forces shape queer, trans, and non-binary health, focusing on stigma, discrimination, and access to care. It highlights minority stress, structural inequalities, the politicisation of gender-affirming care, and community-led responses, with the aim of advancing more equitable and inclusive health policy and practice.

BMC Medicine is calling for submissions to our new Collection invites submissions focusing on the prediction of pathogen evolution and immune evasion in response to vaccination efforts. We seek research that explores modeling techniques, the impact of vaccines on infectious disease dynamics, and the mechanisms behind immune evasion. By fostering a deeper understanding of these critical issues, this Collection aims to contribute to improved public health strategies and vaccine development.

This Collection focuses on reliability, fault diagnosis, condition monitoring, and lifetime prediction of power electronic devices and systems. Topics include failure mechanisms, degradation modeling, AI-driven diagnostics, digital twins, and reliability-oriented control.

This Collection focuses on the intersection of immunology and genomics, inviting research that elucidates the genetic basis of immune responses and how the immune system shapes genetic variability and disease. We welcome submissions on gene regulatory mechanisms in immunity and on integrating immunogenomic data to advance understanding of normal immune function and immune-related disorders. Our goal is to advance knowledge in this dynamic field of immunogenomics.

This Collection aims to elucidate the potential of emerging devices in shaping the landscape of in-memory computing for AI applications.

This collection examines bio-inspired and metaheuristic optimization approaches for solving complex, high-dimensional problems in artificial intelligence and complex systems.

This Collection explores advanced power electronics for data centers, including HVDC architectures, SiC/GaN converters, protection, energy storage, and power quality solutions, addressing efficiency, resilience, and sustainability from theory to deployment.

This Scientific Reports Collection welcomes original research on molecular mechanisms, behavior, and chronomedicine strategies.

Higher education institutions worldwide are facing a growing mental health crisis among students, marked by a high burden of common mental disorders and limited capacity to respond. This Collection brings together interdisciplinary and global research spanning epidemiology, clinical science, public health, and translational approaches to inform more effective and equitable models of care.

In recognition of the role this research plays in UN Sustainable Development Goals 3, 5, and 10, this Collection is open to research on migration and health, including studies assessing permanent or temporary migration and those looking at within- or between-country migration.

In recognition of the role this research plays in UN Sustainable Development Goals 3, 5, and 10, this Collection invites research into pharmacoequity, including studies measuring equity and those testing methods to improve equity.

This collection invites research on crop innovation, varietal improvement, nutrient enhancement strategies, agronomic performance, and dietary and public health impacts.
