On the cover: The cover represents a visual metaphor for the pipeline developed by Saez Atienzar et al. in this issue of Cell Genomics, which uses large-scale genomics and transcriptomics to identify promising drugs for C9orf72-related diseases, such as amyotrophic lateral sclerosis and frontotemporal dementia. The front of the image features a selected drug, symbolizing the successful repurposing of a therapeutic candidate (acamprosate). In contrast, other drugs are depicted as being rejected or left behind, representing those deemed ineffective by our screening process. This captures the essence of our proposed repurposing strategy: a rigorous, data-driven approach to narrow down effective treatments from a broad pool of candidates.

On the cover: In this issue of Cell Genomics, Xu et al. present their findings that Epstein-Barr virus (EBV)-host genetic interaction predisposes susceptibility to nasopharyngeal carcinoma (NPC). This EBV-related cancer, though rare in most parts of the world, is highly endemic in southern China. Illustrated on the cover, the red virus and double-stranded DNA symbols capture the strong interaction between the high-risk subtype of EBV and susceptible HLA alleles. This interaction is the major determinant of NPC risk among southern Chinese populations. The cover art was created by the artist Rui Xie.

Causality-enriched epigenetic clocks In this issue, Kejun Ying et al. identify CpGs that may be causally linked to aging-related traits using epigenome-wide Mendelian randomization. They develop the epigenetic clocks DamAge and AdaptAge, which track adverse and adaptive outcomes, respectively. The cover image conceptualizes the relationship between DNA methylation and the aging process as a cascade of dominoes that links the youthful individual with the old one. Each domino represents a key CpG site with a causal influence on aging undergoing methylation (denoted by the letter ‘M’). The falling of the dominoes embodies causal effects of these methylation events, suggesting a sequential impact on the progression of aging. See Ying et al.

On the cover: How does a single cell control its behavior? This is Euplotes, a unicellular organism with a highly complex morphology. The thick bundles of cilia called cirri (seen here on the cover) emanating from its lower surface are used for walking and swimming. In this issue, Laeverenz-Schlogelhofer and Wan demonstrate the bioelectrical basis for gait control in this walking single cell. Simultaneous electrophysiological recordings and high-speed imaging reveal that membrane potential regulates cirri activity, enabling Euplotes to rapidly switch between forward walking and turning. Depolarization events orchestrate the cell's highly coordinated turning maneuver, with distinct cirri behaving differently. SEM micrograph by Christian Hacker; used with permission.

On the cover: The microscopic fossil ostracod crustacean shown is used as a time machine to reconstruct past deep-sea ecosystem changes. In this issue, Moriaki Yasuhara, Huai-Hsuan May Huang, Raine Wing Ki Chong, and their colleagues revealed the 500,000-year history of the Southern Ocean deep-sea ecosystem. The researchers found that the present-day Southern Ocean deep-sea ecosystem was established at a major climatic transition ∼430,000 years ago. After that, both deep-water temperature and food supply (via surface plankton production related to iron fertilization that eventually sinks to the deep-sea floor) substantially affected their deep-sea ecosystem in different ways. The team highlights the importance of the Southern Ocean deep-sea ecosystem as a “canary in the coal mine” for future anthropogenic climatic changes on our planet, and especially highlights the need to carefully think about how we proceed with ocean-based climate interventions as they mitigate temperature rise but also affect surface production.

On the cover: The image is a representation of a barrier between the cytoplasm of a Tetrahymena cell and its cilia, which appears to be part of the mechanism that regulates the passage of material into and out of the cilia. The barrier contains nine pores through which pass microtubule doublets that continue out into the axoneme of the cilia. The size of the outer region of the pore is appropriate for passage of complexes, called “intraflagellar transport particles,” which travel along the microtubules and carry components for assembly of the cilia. Proper control of the flow of this material is essential for formation of fully functional cilia. A report by Ounjai et al. (pages 339–344) in this issue provides insights on the structure and composition of this regulatory system. Image prepared by Puey Ounjai.

The image vividly illustrates the extensive organic filamentous networks, abundant with immune response-related proteins such as calprotectin (displayed in red), myeloperoxidase (in yellow), and DNA molecules (in blue). Originating from intricate host-microbe interplay, these organic networks promote the heterogeneous nucleation and precipitation of inorganic particulates, culminating in the formation of macroscale aggregates known as "matrix stones". This process embodies a unique 'double-edged sword' effect of the host immune response to pathogens in pathological renal biomineralization.

In this issue on broad concepts in microbiology we celebrate the 25th anniversary of Trends in Microbiology and explore the concepts that have grown through the history of the journal and the emerging areas within these topics. On pages 376–385, Ariel Amir and Nathalie Balaban review recently invoked methods which rely on the statistics of cell size and cell cycle durations to gain insights into the regulation of and control over biological processes within cells, through the combination of single-cell level measurements and quantitative stochastic models. The cover image shows an artist's depiction of a variable microbial cell population. Cover image from Equinox Graphics.

In this issue, Gerber-Tichet et al. provide an update on the expanding role of the function of Toll-like receptor 4 (TLR4), a germline-encoded pattern recognition receptor (PRR). The archetypal role TLR4 is the detection bacterial wall components, including lipopoly- and lipo-oligo-saccharides (LPS and LOS). The cover shows antigen-presenting cells (APCs), which are the sentinels of the immune system, containing cell surface dimers of TLR4 dimers, one of the ten members of the TLR family. However, TLR4 is not a one trick pony – it can also generate anti-viral innate immune responses via TRIF-related adaptor molecule-associated signalling directly or indirectly (e.g., Ebola or adenovirus via an alpha-defensin bridge, respectively).

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.

Since our launch, each article has represented a small piece of materials research, a kind of “building block” contributing to the overall progression of materials science. This “building block” theme has been a motif across the years of Matter, reflected in our branding, and now commemorated by the cover, which depicts a celebratory “five” among building blocks. The five colors (white, red, blue, green, and yellow) are also no accident, representing both 5 years as well as five innovations our team has brought to academic publishing (see this month’s editorial by Steve Cranford).

Range expansion promotes cheaters Pseudomonas aeruginosa colonies develop spatial patterns through cooperative swarming. During experimental evolution experiments, cheaters emerged, leading to the disruption of the spatial patterns and a decline in population fitness. The authors found that populations were more vulnerable to invading cheaters in a spatially extended system due to a higher level of cooperation. This collapse of cooperation during microbial range expansion is shown to be tied to its spatial dynamics: spatial structure promoted the invasion of cheaters, while in well-mixed cultures cheaters remained at low frequencies.

The ultimate resolution for printing colour images is dictated by the diffraction limit of visible light. To achieve this limit, Joel K. W. Yang and co-workers from IMRE, A*STAR in Singapore use a nanopatterned surface composed of silver–gold nanoposts and a backreflector over a silicon substrate. The metallic nanostructures interact with the incident light of a bright-field microscope through surface plasmon resonances and reflect a wide range of colours depending on the diameter and spacing of the nanoposts. The cover shows a false colour close-up of this nanopatterned surface coding for a portion of the left eye in the famous Lena image.

In the wings of butterflies, for example, a combination of multilayer interference, optical gratings, photonic crystals and other optical structures gives rise to complex colour mixing, but it remains a challenge to create artificial replicas of natural photonic structures. Now Ulrich Steiner, Jeremy Baumberg and co-workers have used a combination of growth processes — including self-assembly, sputtering and atomic-layer deposition — to fabricate photonic structures that mimic the colour-mixing effect found on the wings of the Papilio blumei butterfly, and to make new structures that display enhanced optical properties.

Research into public perceptions of nanotechnology is becoming more rigorous with social scientists developing and testing increasingly complex theoretical models, as demonstrated by three papers in this issue. Dan Kahan and coworkers investigated the influence of cultural factors - in particular, whether individuals were pro- or anti-commerce - on attitudes towards the risks and benefits associated with nanotechnology; Dietram Scheufele and colleagues combined the results of public surveys in the US and Europe to explore the influence of religious beliefs on public perceptions of nanotechnology. In the third study Nick Pidgeon and co-workers found that energy applications of nanotechnology were viewed more positively than health applications in workshops organized in the UK and the US.

A novel Aggregation-Induced Emission (AIE)-based fluorescent sensor for imaging the spatial organization of HER2 receptors on the membrane of HER2 overexpressing cancer cells. When the receptors are clustered, the molecules undergo a reversible “turn-on” process. The clusters are disrupted upon exposure to an immunotherapy (Trastuzumab), reducing the emission.

On the cover: Cell Metabolism is turning ten! We are celebrating a decade of publishing high-quality metabolic research, and for this special anniversary we asked Bang Wong, the artist who drew the inaugural cover in 2005, for his take ten years later. His new cover conceptualizes how, in the last decade, key technical advances have led to the top ten breakthroughs in the metabolism field, with the spiral unravelling the top ten challenges for the years ahead of us. As the artist himself explains, he “carried over the golden spiral as a metaphorical bookend to a decade of transformative advances in metabolic research. As science is a story that continuously unfolds, the descriptions of catalytic techniques and breakthroughs are arrayed uninterrupted with the challenges ahead.” For more details about this cover and the original one, check out our anniversary page at http://www.cell.com/cell-metabolism/ten.

ONLINE COVER Reversing the Hands of Time. Inflammaging is the age-associated increase in systemic inflammation, which can have negative effects on blood cell production and the immune system. Using a mouse model of premature hematopoietic aging, Ramalingam et al. identified thrombospondin-1 (Thbs1) as a driver of age-associated changes to hematopoietic stem cells (HSCs). Deletion of Thbs1 prevented HSC myeloid bias, loss of HSC self-renewal, and systemic signs of inflammaging in aged mice. This month’s cover illustration depicts the process of HSC inflammaging as a pocket watch. Thbs1 gene deletion causes the watch hands to move backwards, which reverses aging-associated HSC defects and turns back the clock on inflammaging. Credit: Rioka Hayama

The image shows individual cells of one of the strains used in this study, where key factors localized in and around the nucleus are visualized by means of fluorescent protein tags: the single-stranded DNA-binding RPA complex, shown here in green, serves as a reporter for sites of damaged DNA; the nuclear periphery is decorated in red, and nuclear pores are in blue. The study shows how—in response to polymerase-blocking lesions—local clusters of single-stranded DNA emerge in the wake of replication forks and are resolved far away from sites of ongoing genome replication in dedicated subnuclear compartments, so-called postreplicative repair territories (PORTs).

Cover Credit: Reduction-activatable PROTAC prodrug nanoparticles for tumor-targeted protein degradation and anticancer therapy. The reduction-activatable PROTAC prodrug nanoparticles (NPs) were engineered by self-assembly of the PROTAC-conjugated amphiphilic diblock copolymer and further functionalized with a CRGDK ligand. The resulting PROTAC prodrug NPs can specifically target tumor cells and be efficiently internalized by recognizing neuropilin-1 (NRP-1), which is overexpressed on the surface of tumor cells. Remarkably, the PROTAC prodrug NPs efficiently degraded the protein targets BRD4 and CDK9 for inhibiting tumor growth in an mouse model of MDA-MB-231 triple-negative breast cancer. More importantly, the PROTAC prodrug NP can serve as a platform for co-delivering chemotherapeutic agents (e.g., doxorubicin, DOX) to perform combinatory cancer therapy.

In this issue of Trends in Neurosciences, Benayahu Elbaz and Brian Popko review the molecular pathways that govern the development of oligodendrocytes, the specialized glial cells responsible for myelinating the central nervous system (CNS). The cover image shows a newborn foal, along with its dam. Foals are born well myelinated, which correlates with their ability to stand and walk immediately following birth. In contrast, mouse pups are born helpless and without mature oligodendrocytes or myelin, making them ideal model organisms to study developmental myelination and factors that disrupt this critical process. People are born with some myelin, but the process of human CNS myelination is not complete until adulthood. Cover image by iStock/janpla01.

Humans and animals are intrinsically curious. They explore their environments, even when there is no immediate reward and despite the potential presence of threats. Understanding how curiosity guides exploration is a fundamental question in neuroscience and an important challenge for artificial intelligence. However, research on this topic has been conducted largely separately in the two fields. In this issue of Trends in Neurosciences, Modirshanechi and colleagues discuss recent progress in experimental neuroscience and computational modeling, providing a framework which allows to compare studies from different disciplines using the same language. The cover illustrates a curious rodent driven to explore an infinite, impossible space. Cover art designed by Weronika Reroń.

BOLD troubles Functional magnetic resonance imaging (fMRI) is a key tool for understanding brain function. Korponay et al. show that the blood oxygenation level-dependent (BOLD) signal — which fMRI uses to measure brain activity — is susceptible to artefacts from low-frequency blood flow signals (sLFOs), which can produce false positives in functional connectivity. These artefacts, linked to changes in respiration and heart rate during scanning, distort connectivity measures. The authors develop a specialized sLFO denoising method, which improves the accuracy and reliability of functional connectivity findings. See Korponay et al. Image: Marc Raley.

As CO2 levels increase, plants produce more biomass. However, the concentration of essential elements is reduced.

On pages 809–820, Michael Kaspari and Ellen Welti argue that nutrient dilution could be a key driver in global herbivore declines. Image credit: David Rintoul.

Cover picture: The physical attributes of the extracellular environment can inform internal cell processes and responses to external stimuli. The basement membrane of many tissues, including vascular tissues, displays a complex topographic mixture of ridges and grooves, bumps and pores, with dimensions that range from nanometer to micrometer. To better understand how the combination of multiple topographic features influences vascular endothelial cells, McKee et al. have generated highly porous polyelectrolyte multilayer films that closely mimic the architectural features and stochastic nature of in vivo vascular basement membrane. The front cover artwork combines an AFM topographic height image of the surface we have created, with an artist's interpretation of cells interacting with the surface (artwork by John H.

Boosting CO2 conversion with Mo oxycarbides Molybdenum carbides are promising heterogeneous catalysts for CO2 conversion chemistry, but they typically require harsh preparation conditions and suffer from poor stability. Now, Jiafeng Yu, Jian Sun and colleagues have shown that molybdenum oxide, produced by flame spray pyrolysis synthesis, is stable at 600 °C for 2,000 hours during the reverse water–gas shift reaction. Extensive characterization revealed the in situ formation of a cubic α-molybdenum carbide with unsaturated surface oxycarbides (depicted on the cover) that serve as active sites for CO2 conversion.

In this issue of Trends in Cognitive Sciences, Shaun Gallagher and colleagues propose a ‘pattern theory of compassion’ that clarifies distinctions between empathy, sympathy, and compassion. The pattern theory identifies a set of diverse components that form a dynamic Gestalt constitutive of compassion. A review of neuroscientific studies of compassion provides evidence to support the pattern theory, and the processes and factors that make up the pattern can contribute to guide compassion training. The anthropomorphic cartoon on the cover depicts some of the differences between empathy, sympathy, and compassion. From left to right: empathy (quasi-isomorphic) is signified by the quasi-same color for empathizer-empathized; sympathy (related but not isomorphic) is signified by similar band colors; compassion (non-isomorphic) is signified by different colors.

There is a growing appreciation of the functions of tissue-resident immune cells and their importance in immune surveillance and throughout the immune response. Recent findings are providing new insights into the mechanisms targeting these cells to specific tissues, and how these populations are maintained in homeostasis and respond in times of immune challenge. Trends in Immunology is excited to announce a special year-long series of articles devoted to examining tissue-resident immune cells and their diverse functions. In the inaugural article of this series, on pages 30–39, Shannon Turley and Jonathan Chang discuss the dynamic mechanisms that govern lymph node stromal cells during homeostasis and active immunity. The cover depicts, by confocal immunofluorescence microscopy, the close association of dendritic cells (red) with an extensive and interconnected fibroblastic reticular cell (FRC) network (cyan) populating lymphoid tissue. Through the dynamic production of various chemotactic and survival cues, FRCs and other stromal cell subsets coordinate the migration, positioning, and homeostatic maintenance of immune cells.

In this Special Issue, Trends in Immunology explores the complex relationship between the immune system and cancer, discussing how some immune processes are co-opted by cancer for its own benefit, and highlighting how in some instances, immunity can be harnessed for therapeutic purposes. We also discuss how the immune system is impacted by anti-cancer therapies, and how in turn this affects the outcome of the treatment. This battle is illustrated here: the crab puts up its own defense against anti-cancer therapy and cytotoxic immune cells, but it is also shielded from attack by pro-tumorigenic immune cells.
