Heterosis has driven animal crossbreeding successes for over a century, yet the non-additive genetic mechanisms behind it, including dominance, epistasis, and gene interactions, remain poorly understood. This collection explores the molecular basis of hybrid vigor and its translation into predictive breeding, welcoming studies on genomic prediction of crossbred performance, multi-omics integration, machine learning, and gene-editing validation in livestock, poultry, and aquaculture.

This cross-journal Collection focuses on complex climate risks, including cascading impacts, compound events and tipping-point risks. It brings together research on how to reduce vulnerability and build resilience across sectors and scales, from facilities and cities to regional and global systems.

The collection would focus on emerging research using retinal/fundus imaging, multimodal imaging data, image analysis, and AI-driven models for the screening, diagnosis, prognosis, and risk prediction of systemic diseases. Potential topics could include, but are not limited to, cardiovascular disease, diabetes and related complications, kidney disease, neurodegenerative disorders, and other systemic conditions where retinal imaging may provide clinically relevant biomarkers.

In this Collection, we aim to showcase diverse strategies for developing programmable chemical systems through molecular, supramolecular, and systems-level design.

This collection invites manuscripts that highlight research advancing the synergistic operation, control, and co-planning of AI Data Centers.

With this Collection, editors invite primary, translational, and clinical research submissions focusing on women’s brain health.

This Humanities and Social Sciences Communications Collection invites scholarship on social development in post-Soviet and satellite states, including how historical legacies, institutional reforms, and grassroots movements have shaped the lived realities of individuals across the region.

This Collection highlights original research that explore capture architectures, multiphase flow characterization, pipeline and injection modeling, and integration of thermal, chemical, and geomechanical effects. Studies addressing operational safety, scalability, energy efficiency, and monitoring technologies are particularly welcome.

This Collection brings together studies that deepen our understanding of tumour microenvironment remodelling, from mechanistic insights to anti-cancer therapies.

This Collection focuses on cutting-edge developments in battery storage technologies, with emphasis on materials innovation, cell and pack design, and performance optimisation.

This Scientific Data collection of articles will showcase data related to the anatomy, biomechanics, neuroscience, and kinematics of hand movement.

This Collection highlights cutting-edge research on Digital Twin design, development, and applications for smart industrial systems. It covers modeling, analytics, predictive maintenance, manufacturing, robotics, supply chains, cybersecurity, and sustainability across domains like energy, healthcare, transportation, agriculture, and smart cities.

Neutron and synchrotron radiation methods have become indispensable tools for the characterization of metallic materials, offering unique insight into structure, microstructure, stress, and phase evolution across multiple length scales.

Cardio-oncology addresses cardiovascular complications in patients with cancer, from treatment-related cardiotoxicity to thrombosis, heart failure, arrhythmias, valvular and pericardial disease. This Collection seeks multidisciplinary research on the role of cardiovascular imaging—including echocardiography, CMR, CT, nuclear and hybrid imaging—in early detection, risk stratification, monitoring, biomarkers, AI, and imaging-guided management to improve outcomes across cancer care.

Since Russia's 2022 full-scale war, Ukraine's pioneering harm reduction system has faced funding cuts, mass displacement, and occupation. This collection in Harm Reduction Journal invites research articles, reviews, and commentaries on wartime service continuity, policy and funding shifts, gender-related access barriers, adapted harm reduction strategies, mutual aid, provider burnout and trauma, and drug policy change amid Ukraine's ongoing war.

This collection invites contributions on experimental, computational and theoretical work applying advances in artificial intelligence to the field of synthetic biology.

This Collection invites research on the critical intersection of climate change and nutrition, exploring how environmental factors impact food systems and nutritional outcomes. We welcome submissions that address sustainable farming practices, food security, resilience, and adaptation strategies, aiming to inform policy and practice for a healthier, more sustainable future.

This Collection invites research focused on the oral health of girls and women, exploring the unique challenges and needs they face. We welcome submissions that investigate the interplay between oral health, hormonal changes, nutrition, and systemic health conditions, with the aim of promoting effective strategies for improving dental health outcomes in this population.

This Collection aims to gather pioneering research on the application of AI and machine learning for reservoir forecasting and production optimization in the petroleum industry. We welcome submissions that explore innovative methodologies, real-time monitoring techniques, and the integration of digital twin technology, all aimed at enhancing reservoir management and oil production efficiency.

BMC Pregnancy and Childbirth is calling for submissions to our Collection on Midwifery models of care.
