        <description><![CDATA[Human activities are driving a global decline in biodiversity and are interfering with the natural processes essential for human well-being. Achieving climate and development goals is impossible without keeping nature intact. In this article, we establish the urgent need for a paradigm shift toward a “Nature Positive” (NP) future, where the health and resilience of the Earth system are recognized as the fundamental basis for human prosperity. This requires that humanity acts to halt and reverse the loss of nature by 2030. The Kunming-Montreal Global Biodiversity Framework (GBF) provides a critical roadmap for this NP goal, and global policy increasingly recognizes that environmental targets can only be effective when integrated with global climate, ocean, and human development agreements. This requires a biodiversity conservation approach that accounts for both biotic and abiotic components of the Earth system. We assess the adequacy of GBF targets for stabilizing the Earth system and highlight key gaps. We employ the Three Global Conditions Framework (3Cs), which categorizes landscapes by human impact levels as a practical method for guiding appropriate NP actions, and we extend its application to the marine realm. We outline specific actions and metrics for patterns and processes across all scales needed to achieve biodiversity conservation in synergy with climate stabilization and securing freshwater systems. Our findings emphasize that preventing the loss of intact biomes, ecosystems, and species assemblages is the most critical strategy while acknowledging the urgency of extinction prevention and the need for restoration. Additionally, we highlight the importance of incorporating Indigenous and local knowledge systems alongside scientific methods to achieve effective and equitable conservation outcomes. Finally, we discuss the need for economic transformation and the private sector’s role in fostering an NP future.]]></description>

        <description><![CDATA[The importance of food safety to public health is reflected in its inclusion in the United Nations Sustainable Development Goals (SDGs)—SDG 2 (Zero Hunger), SDG 3 (Good Health and Well-being), and SDG 12 (Responsible Consumption and Production)—and the World Health Organization’s food safety strategy. Its inclusion across multiple areas underscores how food safety is not an isolated objective but is closely tied to broader public health and sustainability goals. While the public often expects food to be “absolutely” safe, experts recognize that all foods carry a residual risk of causing foodborne illness and that zero risk is neither achievable nor desirable. Advances in diagnostics and surveillance systems (e.g., increases in test sensitivity and specificity) have increased the frequency of hazard detection in foods, including detection of hazards at levels that may pose minimal public health risks. However, efforts to manage these negligible risks can divert attention from more significant threats and may introduce unintended consequences that outweigh the intended benefits. To address this, holistic approaches and trade-off risk assessments are needed, accounting for the interrelationship between the health of humans, animals, and the environment (i.e., One Health) and evaluating both the costs and benefits of food safety measures, including direct expenses, externalities, social or legal constraints, and consumer preferences. Key tools enabling these risk assessments include Monte Carlo simulations and other modeling tools that are also being adopted for food safety applications, such as geographic information system models, agent-based models, and artificial intelligence (AI)-based predictive tools. These efforts can help define quantitative food safety goals that ensure appropriate, but not absolute, safety, so long as implemented controls are validated and verified. Technological advances, such as AI-enabled risk negotiation, offer new opportunities to integrate trade-offs in risk analysis and support more balanced, effective food safety strategies.]]></description>

        <description><![CDATA[Global wastewater production exceeds 359 billion m3 annually, of which only 52% is treated, mostly in expensive and resource-consuming processes. Microbial electrochemical technologies (METs) offer a transformative approach to sustainable wastewater management by converting waste into valuable resources such as energy, clean water, and nutrients. They present a viable solution to the United Nations’ Sustainable Development Goal 6 (to ensure access to water and sanitation for all) by enhancing both sanitation and resource recovery. METs, including microbial fuel cells (MFCs) and microbial electrolysis cells (MECs), harness electrogenic microorganisms to oxidize organic matter, generating electric energy or producing energy carriers like hydrogen and methane. METs also enable recovery of nutrients, such as ammonium and phosphates, which are essential for agriculture, thereby closing resource loops in a circular economy. Despite their potential, challenges remain in scaling up METs for widespread application. Pilot-scale MFCs and MECs have demonstrated feasibility, achieving up to 90% chemical oxygen demand removal and producing electric power, methane, or hydrogen from wastewater. However, high capital costs, material limitations, and energy efficiency barriers hinder commercialization. Innovations in electrode design, modular configurations, and integration with existing wastewater treatment processes (e.g., anaerobic digestion, membrane bioreactors, or constructed wetlands) are advancing METs toward higher technology readiness levels (TRLs 4–8). Field applications, like a system for urine-based electricity generation in underserved regions, highlight METs adaptability and societal impact. The transition from laboratory to real-world implementation requires scaling, process integration, and further optimization to reduce costs and improve performance. By aligning with circular economy principles, METs can transform wastewater into a resource, contributing to energy security, environmental sustainability, and global sanitation goals. Future research should focus on scalable designs, economic viability, and interdisciplinary collaboration alongside understanding and optimizing the microbial “black box” to enable METs to transform previously unused wastewater streams into valuable resources with targeted applications.]]></description>

        <description><![CDATA[The global obesity crisis involves an unprecedented and rapid change to the human phenotype. Conferring vast levels of avoidable morbidity and mortality at enormous cost, it has proved refractory to previous policy-led action. This article reviews recent developments in our understanding of obesity and its links to the climate co-crisis, aiming to inform evidence-based, societal-level actions to address both. Recent therapeutic developments now offer transformative interventions for millions of people living with obesity. However, treating all affected adults and children with major bariatric surgery or lifelong anti-obesity medication is unsustainable given the risks and costs. The obesity crisis has been driven primarily by the transformation of our food environment toward diets dominated by ultra-processed foods (UPFs) that exert multiple addictive and obesogenic mechanisms. Emerging evidence shows that not all UPFs have the same impact: processed meat and low-fiber, energy-dense UPFs are linked with poorer outcomes compared with less energy-dense, high-fiber, plant-rich UPFs, indicating that more nuanced classifications would be helpful. This food system also contributes significantly to climate change and other environmental harms, primarily through ruminant meat consumption. Both climate change and obesity are driven by unsustainable, but profitable, consumption. Solutions exist but have not been adequately implemented owing to a lack of political will. They require food system reforms that replace energy-dense UPFs with unprocessed foods and reduce animal-sourced foods. Accumulating evidence supports prioritizing actions to remove market distortions via increasing cost transparency, taxing unhealthy foods (redirecting the proceeds to public health), combating marketing, effective food labeling, facilitating healthy food choices, promoting healthy living environments, and public and professional education. New economic models, market demand shifts, and technological innovation should all be harnessed to overcome economic and political barriers, and food system reform should be integral to future actions to achieve the Sustainable Development Goals. This transformation to improve both human and planetary health will require interdisciplinary scientific advocacy and coalition-building across society. During the COVID-19 pandemic, societies recognized how rapid, concerted, science-led action can effectively address a global threat; a similar societal shift is required to motivate the political action needed to address the obesity crisis.]]></description>

        <description><![CDATA[The relentless advancement of artificial intelligence (AI) across sectors such as healthcare, the automotive industry, and social media necessitates the development of more efficient hardware solutions that can implement diverse learning algorithms. This lead article explores the evolution of AI learning algorithms and their computational demands, using autonomous drone navigation as a case study to highlight the limitations of traditional hardware. Traditional hardware, based on the von Neumann architecture, suffers from limited computational efficiency due to the separation of compute units and memory, also known as the “memory wall” problem. To overcome this barrier, this article discusses novel approaches to AI hardware design, focusing on compute-in-memory (CIM) techniques and stochastic hardware. CIM offers a promising solution to the memory wall problem by integrating computing capabilities directly into the memory system. This article details state-of-the-art developments in CIM for different memory types and at various levels of the memory hierarchy to support essential AI compute functions. We also discuss the use of CIM in developing neuromorphic hardware capable of accelerating biologically inspired algorithms, such as spiking neural networks. Furthermore, we highlight how stochastic hardware can exploit the error resilience of AI algorithms to enhance energy efficiency. Encompassing the full stack of AI systems, from learning algorithms to circuit and device-level techniques and architectures, this article provides a comprehensive roadmap for future research and development in AI hardware.]]></description>

        <description><![CDATA[Of the numerous anthropogenic pressures that are being exerted on ecosystems globally, plastic pollution and climate change are potentially the most pressing. This is particularly true when they co-occur as joint stressors. These are interlinked with respect to their root cause (the overconsumption of finite resources) and their effects in natural and anthropogenic systems and processes. This review focuses on a growing area of research into how climate change can, by transforming plastic pollution from a reversible to a poorly reversible contaminant, exacerbate the abundance, distribution, exposure, and impacts of plastics and associated chemicals in our waters, soils, biota, and atmosphere. There is a growing body of evidence suggesting that climate change and plastic pollution can have significant and often interactive ecological effects, particularly among the higher trophic levels within the food web. The rational response to confront these effects is to address the pollution at source by rapidly and meaningfully reducing emissions into the environment. We discuss challenges but also solutions, through future research, policies and public awareness, that must harness the same enthusiasm that made plastic a fundamental cornerstone of the modern world in the first place. The threat that plastics produced, used and discarded today could cause global-scale impacts in the future is compelling motivation to take appropriate action now.]]></description>
