We successfully employ readily available oxamic acids as carbamoyl radical precursors to couple with pyridinium salts, selectively introducing the amide group into pyridine architectures. The key innovation lies in the successful integration of an acridinium-based photocatalyst, which enables the formation of amide bonds through a consecutive photoinduced electron transfer process.

Human causes and costs of wildfire The impacts of climate change on wildfire occurrence and intensity have received increasing attention. Lampe and colleagues show that while other human impacts led to burnt area reduction over time, these actions have masked the contribution of climate change in increasing global burned area and increasing probability of months with high burning. Park and colleagues combine fire–vegetation models with a chemical transport model and health risk assessment framework to show that human mortality from fire fine particulate matter is increasingly attributable to climate change.

Ethanol is a cytotoxic compound that perturbs the development of the central nervous system. Experimental evidence shows that silver sub-nanoclusters (silver atomic quantum clusters, AgAQCs) electrocatalyze ethanol oxidation under physiological conditions. The observation that AgAQCs-induced ethanol electrocatalysis takes place only in the presence of mammalian cultured cells suggests that the cellular plasma membrane provides the required potential for this reaction and prevents ethanol toxicity.

Levayer and Lecuit (pages 61–81) review the biomechanics of the actomyosin network and discuss how the complex dynamics of this network, alongside its ability to self-organize and respond to mechanical feedback, all contribute to key cellular processes such as cytokinesis, cell migration and epithelial morphogenesis. Also in this issue, Davidson (pages 82–87) discusses the physical laws that govern tissue assembly with an introduction to the mechanics of epithelial sheet interactions, and Varelas and Wrana (pages 88–96) review recent work on the developmental cross-talk between the Hippo pathway – key to determining organ size – and other important signalling cascades, such as those mediated by TGFβ_and Wnt.

Organelle communication is a growing research field, and its impairment is increasingly associated with mechanisms of cellular dysfunction. Recent studies have shed light on the pivotal role of lipids in inter-organelle communication, revealing their influence on processes such as organelle membrane fission and remodeling. In this issue, Domingues et al. explore how lipids mediate inter-organelle communication. The authors highlight emerging techniques that improve lipid detection and quantification, paving the way for a systematic understanding of lipid-mediated intracellular communication.

Nanoparticles can deliver a variety of cancer drugs directly into tumour cells, which increases the efficacy of the treatment while reducing side effects. Small interfering RNAs (siRNAs) have shown promise as therapeutic agents but it is difficult to get them into cells. Now Daniel Anderson and co-workers have demonstrated that self-assembled DNA nanoparticles can reliably deliver siRNAs into cells and silence target genes in tumours. As shown in this illustration, the DNA nanoparticles are tetrahedral in shape, with six protruding arms. DNA nanoparticles have a number of properties that are useful for drug-delivery applications: it is relatively easy to control their size and to bind either drug molecules or targeting ligands to them.

Recent studies have highlighted the complexity of platelet biology, revealing their diverse roles beyond hemostasis. Pathological platelet activation is now recognized as a key contributor to thrombosis and inflammation, both of which are central to cardiovascular disease (CVD). Emerging research emphasizes the considerable impact of demographic factors—such as age, sex, race, and ethnicity—on CVD risk and responses to antiplatelet therapies. In this issue, Jain, Tyagi and colleagues review the influence of genetic and non-genetic factors including age, sex, race, and ethnicity on platelet function and responses to antiplatelet therapies. They emphasize the pressing need for further research into platelet biology and cardiovascular outcomes across diverse populations and advocate for tailored therapeutic approaches in CVD based on recent demographic findings. The cover image, conceptualized and designed by Kanika Jain and Tarun Tyagi using BioRender, features a heart, representing cardiovascular health, and hands holding platelets and medications, symbolizing the interplay between pathological platelet activation—associated with thrombosis—and therapeutic strategies crucial for CVD management.

The cover shows a mouse inguinal lymph node after vaccination with the BNT162b2 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine adjuvanted with a lipid nanoparticle-encapsulated mRNA encoding interleukin (IL)–12p70. The lymph node was stained for naïve (yellow) and germinal center (green) B cells, T cells (magenta), and follicular dendritic cells (blue) to visualize the vaccine-elicited immune response. Immunity elicited by SARS-CoV-2 mRNA vaccines have been shown to wane over time, particularly in older individuals. To improve immune durability, Brook et al. adjuvanted the BNT162b2 SARS-CoV-2 vaccine with a mRNA encoding IL-12p70, which amplified vaccine responses even at lower vaccine doses. The authors also developed a strategy to limit expression of the mRNAs to muscle, potentially reducing systemic reactogenicity after vaccination. Together, these data show that mRNA vaccines, like their protein counterparts, benefit from adjuvantation. Credit: Brook et alMAC_Bench/Science Translational Medicine

ONLINE COVER Manipulating Mitochondrial DNA. The cover shows a cross-section of a skeletal muscle fiber stained for cytochrome c oxidase activity (dark brown), an indicator of mitochondrial function, in a mouse treated with a mitochondrial DNA (mtDNA) base editor to correct a mutation in a mitochondrial tRNA. Mitochondrial disorders are often caused by mutations in mtDNA that are difficult to correct with traditional gene editing. Barrera-Paez et al. used a dose-dependent mitochondrial DddA-derived cytosine base editor (DdCBE) to successfully correct a mitochondrial tRNA mutation in mouse heart and muscle. However, at the highest doses of editing, DdCBE induced off-target DNA edits resulting in severe adverse effects in the mice. Together, the results suggest that DdCBE is a promising tool for mitochondrial gene editing, but caution is required to avoid dose-dependent adverse effects. Credit: Jose Domingo Barrera-Paez

This themed issue of Trends in Microbiology explores different aspects of microbial endurance and how microbes endure and flourish in the environments they find themselves in. We examine how bacteria and viruses establish chronic infections – from adaptation and population diversity, to the latent reservoir in HIV as well as how this might be eliminated, and reactivation of latency. We discuss how bacteria respond to stressful conditions from responses from the immune system to antimicrobials and how the stress response is regulated. We also look at endurance in beneficial interactions and how a stable gut microbiota is maintained and how stress can act as a cue in symbiosis. Finally, we explore what endurance might mean for the field of microbiology and how this might evolve in the 21st Century. The cover image by Kip Lyall playfully imagines what microbial endurance might look like if microbes ran in marathons.

On the cover: There are many routes through which we can meet our demise, and our exit from the scene generates a multiplicity of consequences. In this issue devoted to cell death and immunity, we provide a series of articles that examine the many routes to cell death and their immunological consequences. Green (pages 441–444) lays out the molecular landscape of cell death routes. Ravichandran (pages 445–455) discusses mechanisms by which dying cells alert the host to remove their corpses. Griffith and Ferguson (pages 456–466) address the consequences of cell death to immunological tolerance and its alter ego, autoimmunity. Karin and colleagues (pages 467–477) provide insight into routes by which an inflammatory response triggered by cell death can lead to cellular transformation and tumorigenesis. Finally, Yatim and Albert (pages 478–490) examine and opine on the strategies that viruses have developed to co-opt host cell death pathways to their advantage while the host uses these pathways to pursue its self-serving agenda. It is hoped that this collection will stimulate thought and further investigation on the inevitable fate of our cells and the immunological consequences of cell mortality.

To celebrate this milestone with the immunology community, we hosted an open call for cover submissions for our special anniversary issue and are grateful to have received beautiful and creative submissions from across the globe! The winning design featured on the cover of this anniversary issue was designed by Yun Hsuan Elena Lin, a PhD candidate in the laboratory of Dr. John Chang at the University of Californa, San Diego. In her illustration, immune cells are depicted as flowers flourishing from vases in the shape of the number 30. The stalks of the flowers are comprised of DNA, RNA, mitochondria, antibodies, blood vessels, lymphatics, neuronal and glial cells, microbes, and more, highlighting advances in immunology research over the past decades. Model organisms populate the image as well, recognizing their key contributions in driving substantial advances in human immunology. The bouquet captures the diversity of immunological research published by Immunity, painted over a backdrop of dawn that symbolizes the exciting discoveries to come. In this issue, we present a collection of review and perspective articles on innate immunity with a focus on pattern recognition. Rather than recognizing unique aspects of a pathogen, the innate immune system uses families of receptors that recognize shared features of potential threats to the host. Likewise, sensing of endogenous molecular patterns enables maintenance of health. Throughout this collection of articles, we explore the latest understanding of how the innate immune system evolved to ensure that the body responds appropriately to the myriad of microbes in the environment while maintaining regulation of homeostatic functions, how these mechanisms can go awry in disease, and the prospects for harnessing these insights into the development of new therapies.

The photoresponsive polymer material could sensitize the molecular oxygen to generate reactive oxygen species leading to tumor cell death, while polymer materials can be modified to electrolytes to build up bioelectronic devices used for improving biocatalysis (photolysis of water to oxygen) and photoelectric conversion.

m6A mRNA modification in primate aging In this issue, Wu et al. profile the N 6-methyladenosine (m6A) epitranscriptomic landscape of aging nonhuman primate tissues. Their study shows that m6A decoration correlates with gene expression homeostasis and that the methyltransferase METTL3 has a role in m6A epitranscriptomic regulation and myotube maintenance. The cover image shows a dragon, a Chinese symbol of longevity, resembling an mRNA. The dragon has red ‘M’-shaped eyebrows and black pupils with the number 6 at the center. The image is inspired by a Chinese idiom, hua long dian jing — in English, to bring the painted dragon to life by dotting its eyes. The saying metaphorically means ‘providing the finishing touches’. In relation to the authors’ work, to bring this dragon to life — that is, to maintain mRNA stability — the finishing touch is the methylation (invoked by the M-shaped eyebrows) that occurs at the N 6 position of adenosine (invoked by the pupils displaying the number 6). The writing brush represents the METTL3 protein. See Qu et al. Image: courtesy of Yizhu Wang. Cover Design: Lauren Heslop.

On the cover: Liver transplantation is the most effective treatment for end-stage liver disease. And the reconstitution of immune homeostasis post-transplant is critical for the long-term survival. However, the dynamics of immune response patterns under immunosuppressive therapy in post-transplant patients remain largely unexplored. Professor Peng Zhihai's team at Xiang'an Hospital of Xiamen University utilized longitudinal clinical multicohort and single-cell technologies to reveal the processes of immune rejection and homeostasis remodeling after liver transplantation. Under immunosuppressive treatment, the postoperative immune response pattern of stably restored transplant patients underwent a dynamic evolution in one year, progressing through four stages of immune responses, from which a series of molecular markers for the early detection and proactive intervention of graft rejection were identified. On these findings, Peng's team developed a four-stage clinical management framework, offering a more refined guide to the clinical management of patients after liver transplantation.

To celebrate this milestone with the immunology community, we hosted an open call for cover submissions for our special anniversary issue and are grateful to have received beautiful and creative submissions from across the globe! The winning design featured on the cover of this anniversary issue was designed by Yun Hsuan Elena Lin, a PhD candidate in the laboratory of Dr. John Chang at the University of Californa, San Diego. In her illustration, immune cells are depicted as flowers flourishing from vases in the shape of the number 30. The stalks of the flowers are comprised of DNA, RNA, mitochondria, antibodies, blood vessels, lymphatics, neuronal and glial cells, microbes, and more, highlighting advances in immunology research over the past decades. Model organisms populate the image as well, recognizing their key contributions in driving substantial advances in human immunology. The bouquet captures the diversity of immunological research published by Immunity, painted over a backdrop of dawn that symbolizes the exciting discoveries to come. In this issue, we present a collection of review and perspective articles on innate immunity with a focus on pattern recognition. Rather than recognizing unique aspects of a pathogen, the innate immune system uses families of receptors that recognize shared features of potential threats to the host. Likewise, sensing of endogenous molecular patterns enables maintenance of health. Throughout this collection of articles, we explore the latest understanding of how the innate immune system evolved to ensure that the body responds appropriately to the myriad of microbes in the environment while maintaining regulation of homeostatic functions, how these mechanisms can go awry in disease, and the prospects for harnessing these insights into the development of new therapies.

On the cover: The bioenergetic and biosynthetic demands of immune cells are not simply for survival of the cells, but rather, they also fuel critical differentiation processes and effector functions. In this issue of Immunity, we present four review articles that discuss the current understanding of how cellular metabolism impacts the immune cells. Olhenchock, Rathmell, and Vanderheiden (703–713) explain the biochemical mechanisms that underlie how metabolism is adapted to meet the energetic and redox demands of immune cell populations. Many chromatin- and DNA-modifying enzymes make use of substrates and cofactors that are intermediates of metabolic pathways. Glass, Phan, and Goldrath (714–729) examine how metabolic activity can integrate environmental signals with activation-induced gene-expression programs through the modulation of the epigenome and discuss how this integration could lead to context-specific responses. Pearce and Russell (730–742) discuss the role of the mTOR pathway as a metabolic sensor in the tissue microenvironment, how mTOR signaling impacts the differentiation and function of tissue-resident immune cells, and the impact of metabolic constrains in tissues on immune homeostasis and disease. Rickert and Boothby (743–755) discuss recent evidence for the importance of different niches in the development and function of B cells, highlighting the role of the nutrients and metabolic by products that distinguish these sites. The image on the cover aims to capture the impact of metabolic changes in the cellular function and form: the energy, as represented by light, and the change, represented by different colors.

Expanding dimensions In the field of computational materials design, 3D microstructural datasets are crucial for understanding structure–performance relationships through physical modelling. However, 3D imaging can be slow and often has limited resolution compared to its 2D counterparts. In this issue, Steve Kench and Samuel Cooper propose a generative adversarial architecture, SliceGAN, which can use a single representative cross-sectional image to synthesize realistic 3D volumes. In an accompanying News & Views, Alejandro Franco discusses the technique and the potential to extend it to even further dimensional expansion.

On the cover: The protagonist of the special feature in this issue of Immunity is the regulatory T cell (played by the policeman on the cover). Regulatory T (Treg) cells have been under intense scrutiny because of their potent ability to suppress (depicted by the action of the policeman and the red stop symbol) the activity of other cells and hence regulate immune responses such as those that could promote autoimmunity. Recent advances and outstanding issues include an understanding of the molecular regulation of Foxp3, which is the key transcription factor for the Treg cell lineage (Josefowicz and Rudensky, pages 616–625), the developmental and functional differences between thymic-derived and periphery-induced Treg cells (Curotto de Lafaille and Lafaille, pages 626–635), the mechanism of action in vitro and in vivo (Shevach, pages 636–645), the plasticity of these cells and hence the stability of this lineage (Zhou et al., pages 646–655), and finally, their therapeutic potential in the clinic (Riley et al., page 656–665). Waldmann and Cobbold (pages 613–615) provide an overview by relating these challenging subjects to transplantation tolerance. Artwork by Paul Gilligan. Printed with permission from Getty Images.

In her illustration, immune cells are depicted as flowers flourishing from vases in the shape of the number 30. The stalks of the flowers are comprised of DNA, RNA, mitochondria, antibodies, blood vessels, lymphatics, neuronal and glial cells, microbes, and more, highlighting advances in immunology research over the past decades. Model organisms populate the image as well, recognizing their key contributions in driving substantial advances in human immunology. The bouquet captures the diversity of immunological research published by Immunity, painted over a backdrop of dawn that symbolizes the exciting discoveries to come. In this issue, we present a collection of review and perspective articles on innate immunity with a focus on pattern recognition. Rather than recognizing unique aspects of a pathogen, the innate immune system uses families of receptors that recognize shared features of potential threats to the host. Likewise, sensing of endogenous molecular patterns enables maintenance of health. Throughout this collection of articles, we explore the latest understanding of how the innate immune system evolved to ensure that the body responds appropriately to the myriad of microbes in the environment while maintaining regulation of homeostatic functions, how these mechanisms can go awry in disease, and the prospects for harnessing these insights into the development of new therapies.

OPV-PEG can self-assemble with a near-infrared (NIR) photosensitizer to emit both NIR fluorescence and afterglow luminescence. In the presence of biothiols in living animals, the NIR fluorescence of this nanoprobe is turned on, but the afterglow signal remains the same, which permits precise tracking of the probe location while detecting biothiols.

Mitigation shortfalls in mining Sustainable mining relies on vigorous and comprehensive mitigation strategies; however, two studies in this issue show that these measures are falling short. Among artisanal and often illegal mining operations in the Amazon, Fritz et al. demonstrate that while mercury retorts reduce losses, the amount of mercury and CO2 emissions into the environment remains substantial. Globally, Aska et al. draw attention to the number of mine tailing facilities contained within or near the boundaries of protected areas, posing a potential hazard for regional biodiversity.

The {10–10} growth sectors of hexagonal ʟ-cystine crystal capture a tailor-made additive, ʟ-cystine dimethylester, with remarkable fidelity so that the additive molecules in each growth sector have the same preferred orientation with respect to the growth face orientation. This leads to desymmetrization of the crystal structure and anomalous birefringence in the (0001) plane, apparent from the false color map that shows different orientations of the larger refractive index in six {10–10} growth sectors.

Electron scattering off of dinitrogen induces vibrational "ladder climbing" that lowers the effective activation barrier for dissociation at a catalyst surface, enabling ammonia to be produced at conditions much less severe than conventional thermal catalytic processes. The associated Review discusses the evidence for this and other molecular-level phenomena at play in nonthermal-plasma-promoted catalytic transformations of robust chemical bonds.

The first issue of Organic Letters published on July 15, 1999, launching what has become the highest impact communications journal in the field of organic chemistry. After publishing nearly 30,000 Letters, Org. Lett. has spent the past year celebrating its Platinum 20th Anniversary. As the celebratory year comes to a close, the journal salutes the many editors, authors, and reviewers who have led to this success story with a Virtual Issue featuring the most-read (downloaded) Letter published each year so far, 1999–2018. Editor-in-Chief Erick M. Carreira introduces the Virtual Issue with a brief editorial published in the current issue, which features Nobel Laureate Professor E. J. Corey of Harvard University on the cover. Prof. Corey received the Nobel Prize in 1990. His subsequent work has often appeared on the pages of Organic Letters–the Corey group has published 80 Letters over the journal's first 20 years, including two in the first issue. The cover includes a “platinum” image of Prof. Corey surrounded by selected structures featured in several of these Letters. Prof. Corey continues to express his enthusiasm and the journal's optimism for organic chemistry: “One of my hopes is that progress in chemical synthesis and the understanding of its underlying science will continue far into the future”.
