Cellular and organismal aging have been consistently associated with mitochondrial dysfunction and inflammation. Accumulating evidence indicates that aging-related inflammatory responses are mechanistically linked to compromised mitochondrial integrity coupled with mtDNA-driven CGAS activation, a process that is tonically inhibited by mitophagy.

Dinoflagellates are ecologically important and essential to corals and other cnidarians as phytosymbionts, but their photosystems had been underexplored. Recently, photosystem I (PSI) of dinoflagellate Symbiodinium sp. was structurally characterized using cryo-Electron Microscopy (cryo-EM). These analyses revealed a distinct organization of the PSI supercomplex, including two previously unidentified subunits, PsaT and PsaU, and shed light on interactions between light harvesting antenna proteins and the PSI core. These results have implications with respect to the evolution of dinoflagellates and their association with cnidarians.

Arboviral infections are major public health threats, with 100 million people estimated to get sick annually from dengue infection alone. Globally, the risk of arboviruses is likely to further increase both within, and outside of, affected regions due to a combination of factors including climate change, human mobility, and other societal factors. Despite the availability of vaccines for some arbovirus infections, there is a lack of specific antiviral treatment options. Professor Johan Neyts at the University of Leuven, Belgium, has been working on developing antiviral strategies for more than 30 years. His current research focuses on developing antiviral drugs and vaccines against emerging and neglected viruses many of which are arboviruses. In this Q&A, he discusses the risks associated with vector-borne virus infections, challenges in developing efficient drugs for treatment, and current promising efforts to address these challenges.

Multidisciplinary culture-dependent and -independent techniques elucidate the unique microbial nitrogen cycle in nutrient-poor coastal Antarctica soils and reveal the contribution of novel key microbes to their nitrogen budget.

Can many-body systems be beneficial to designing quantum technologies? We address this question by examining quantum engines, where recent studies indicate potential benefits through the harnessing of many-body effects, such as divergences close to phase transitions. However, open questions remain regarding their real-world applications.

Many aspects of human health and disease are influenced by sex as a biological variable and gender as a social construct. A recent study from Nature Communications reported the landscape of outcome comparisions by sex in oncology clinical trials, highlighting the need for a more thorough reporting of sex differences.

Setting goals that are context-specific, relevant, and collectively shared is critical in adaptation. As necessary elements in target setting, imaginaries for adaptation and the language connected to them remain vague. Visuals produced through art-science collaborations can be great allies to (de)construct imaginaries and deglobalise discourses of adaptation.

Here, the authors discuss guidelines to avoid miscommunication of findings in research into sex and gender-based differences in the brain.

Sustainability of African weather and climate information can only be ensured by investing in improved scientific understanding, observational data, and model capability. These requirements must be underpinned by capacity development, knowledge management; and partnerships of co-production, communication and coordination.

Reporting in Nature Communications, Huo and colleagues provide three-dimensional structures of a bacterial immune defense system called Gabija. This work builds on recently published structural and functional studies and contributes strong evidence that protein assembly formation is essential for antiviral function.

Growth chart studies of the human cerebellum, which is increasingly recognized as pivotal for cognitive development, are rare. Gaiser and colleagues utilized population-level neuroimaging to unveil cerebellar growth charts from childhood to adolescence, offering insights into brain development.

Magnetic Resonance Imaging (MRI) is a crucial diagnostic tool within modern healthcare, yet its availability remains largely confined to high-income nations. The imperative to extend MRI accessibility to lower-income countries aligns with the pursuit of universal health coverage, a key target of the UN’s Sustainable Development Goal 3. In an interview with Nature Communications, three scientists dedicated to advancing MRI accessibility in Africa share their insights. These experts include Dr Udunna Anazodo (Assistant Professor at McGill University, Canada and Scientific Director, Medical Artificial Intelligence (MAI) Lab, Lagos, Nigeria), Dr Johnes Obungoloch (Lecturer at Mbarara University of Science and Technology, Uganda) and Dr Ugumba Kwikima (Neuroradiologist, Lugalo General Military Hospital, Tanzania). Our discussion considers the current MRI landscape across African countries and the associated challenges and opportunities. We also cover technological innovations making a difference, such as low field MRI, alongside the role of advocacy initiatives in bolstering accessibility. We finally look ahead to the future of MRI in Africa.

I argue that a surface emitting laser that remains single mode irrespective of its size, a scale-invariant laser, should of necessity also waste light at the edge. This is a fundamental departure from the Schawlow-Townes two-mirror strategy that keeps light away from mirrors and edges to preserve gain and minimize loss. The strategy was implemented in the recent discovery of the Berkeley Surface Emitting Laser (BerkSEL).

Climate change and plastic pollution are interconnected global challenges. Rising temperatures and moisture alter plastic characteristics, contributing to waste, microplastic generation, and release of hazardous substances. Urgent attention is essential to comprehend and address these climate-driven effects and their consequences.

To build pathways to constructive and engaging peer review for the next generation of scientists, we invite all our reviewers to co-review with an Early Career Researcher in their group and let us know. We will ensure ECRs are recognised for their contribution.

Millions of skeletal remains from South Asia were exported in red markets (the underground economy of human tissues/organs) to educational institutions globally for over a century. It is time to recognize the personhood of the people who were systematically made into anatomical objects and acknowledge the scientific racism in creating and continuing to use them.

Contact between organelles such as the mitochondria (Mito) and endoplasmic reticulum (ER) is crucial to coordinate vital cellular homeostatic processes. Here we discuss recent work showing that Mito-ER proximity is regulated by heterotypic complexes between the F-actin polymerizing protein Diaphanous-1) and the mitochondrial dynamics protein Mitofusin 2, which confers increased susceptibility to ischemia/reperfusion injury.

Selecting omic biomarkers using both their effect size and their differential status significance (i.e., selecting the “volcano-plot outer spray”) has long been equally biologically relevant and statistically troublesome. However, recent proposals are paving the way to resolving this dilemma.

Professor Sabine Oertelt-Prigione has been working in the field of sex and gender-sensitive research for the last 15 years. Her current work is focused on trying to understand how sex and gender-sensitive medicine can be successfully implemented in research and practice as well as methods to investigate gender in medical research. Dr. Brandon Turner is a resident physician in the Department of Radiation Oncology at Massachusetts General Hospital and Brigham and Women’s Hospital. He has conducted and is involved in numerous studies looking to evaluate race and ethnicity reporting and representation in clinical trials. In this interview for Nature Communications, Sabine Oertelt-Prigione, and Brandon Turner share their knowledge about the biases that can occur in clinical trials and how they can be minimized.

Tuberculosis is the leading cause of death from a single infectious agent, with over 25% of these occurring in the African region. Multi-drug resistant strains which do not respond to first-line antibiotics continue to emerge, putting at risk numerous public health strategies which aim to reduce incidence and mortality. Here, we speak with Professor Valerie Mizrahi, world-leading researcher and former director of the Institute of Infectious Disease and Molecular Medicine at the University of Cape Town, regarding the tuberculosis burden in South Africa. We discuss the challenges faced by researchers, the lessons that need to be learnt and current innovations to better understand the overall response required to accelerate progress.
