Beyond their roles as environmental constituents, microbiomes act as symbionts, profoundly influencing the health and function of their host organisms. Given the inherent complexity of these communities and the diverse environments where they reside, the components of a metagenomics study must be carefully tailored to yield accurate results that are representative of the populations of interest. This Primer article examines the methodological advancements and current practices that have shaped the field, from initial stages of sample collection and DNA extraction to the advanced bioinformatics tools employed for data analysis, with a particular focus on the profound impact of next-generation sequencing (NGS) on the scale and accuracy of metagenomics studies. We critically assess the challenges and limitations inherent in metagenomics experimentation, available technologies and computational analysis methods. Beyond technical methodologies, we explore the application of metagenomics across various domains, including human health, agriculture and environmental monitoring. Looking ahead, we advocate for the development of more robust computational frameworks and enhanced interdisciplinary collaborations. This Primer serves as a comprehensive guide for advancing the precision and applicability of metagenomic studies, positioning them to address the complexities of microbial ecology and their broader implications for human health and environmental sustainability.</p>","PeriodicalId":74250,"journal":{"name":"Nature reviews.

As a short-range order structural probe, it can be applied to all states of matter: crystalline or amorphous solids, liquids and gases. The method is element selective and highly sensitive, with little compromise required to integrate complex sample environment set-ups. These characteristics make the technique suitable for applications in a range of scientific disciplines, from chemistry and catalysis to environmental science, materials science, physics, biology, medicine and cultural heritage. An XAS spectrum is obtained by measuring the modulation of the sample absorption coefficient as a function of the incident X-ray beam energy. Data are usually collected in transmission detection mode, although fluorescence and electron yield detection modes are often used. The XAS spectrum is divided into two regimes: X-ray absorption near-edge structure and extended X-ray absorption fine structure. In this Primer, an overview of XAS fundamentals is given, together with a description of the experimental set-ups, sample requirements, data analysis and possible applications. X-ray absorption spectroscopy is an element-specific and orbital-specific technique that can probe local atomic and electronic structures, without the need for long-range order. This Primer discusses the background principles, experimental methods and data analysis processes used in X-ray absorption spectroscopy to derive oxidation states, coordination and bond lengths of solids, liquids and gases.","PeriodicalId":74250,"journal":{"name":"Nature reviews.

EUVL has emerged as a critical technique, taking advantage of shorter wavelengths to achieve nanoscale feature sizes with higher precision and lower defect rates than previous lithography methods. This Primer comprehensively explores the technical evolution from deep ultraviolet to extreme ultraviolet (EUV) lithography, highlighting innovative approaches in source technology, resist materials and optical systems developed to meet the stringent requirements of high-volume manufacturing. Beginning with an overview of the fundamental principles of photolithography, the main components and functionalities of EUV scanners are described. It also covers exposure tools that support research and early development phases. Key topics — such as image formation, photoresist platforms and pattern transfer — are explained with an emphasis on improving resolution and throughput. Additionally, persistent challenges are addressed, such as stochastic effects and resist sensitivity, with insights provided into future directions for EUVL, including high-numerical aperture systems and novel resist platforms. This Primer aims to present a detailed review of current EUVL capabilities and project the future developments and evolution of EUVL in semiconductor manufacturing. Extreme ultraviolet (EUV) lithography is used to fabricate features with nanometre-scale resolution. This Primer explores how EUV lithography can be applied to manufacture semiconductor devices, explaining lithographic tools, photoresists and potential future developments.","PeriodicalId":74250,"journal":{"name":"Nature reviews.
