  •   How DNA encodes the start of transcription
    Science (IF 56.9) Pub Date : 2024-04-26
    Jun Wang, Vikram Agarwal

    The central dogma of molecular biology outlines the flow of genetic information from DNA to RNA to proteins. With a limited vocabulary of four nucleotides (A, C, G, and T), DNA encodes an extensive instruction set, including the chromosomal positions where RNAs begin to be transcribed and the magnitudes of their expression. This process, known as transcription initiation (1), begins at transcription

  •   War: not an unlikely topic for science lessons
    Science (IF 56.9) Pub Date : 2024-04-25
    Sibel Erduran

    As a seven-year-old child, I experienced war in Cyprus. Armed conflict has not been far from my conscience ever since. At a time when there are active conflicts in many parts of the world, war is unlikely to be far from many children’s minds globally today. Can a “war” theme be included in science lessons and play a role in helping young children develop into socially responsible scientists and peaceful

  •   Science needs neurodiversity
    Science (IF 56.9) Pub Date : 2024-04-25
    H. Holden Thorp

    All brains work differently. Individuals process information and engage with the world in ways that are influenced by a multitude of biological, cultural, and social factors. In the world of science, these differences are what spark innovation. This is why the scientific community needs to better recognize the enormous potential of neurodiversity and bear in mind that certain behavioral and cognitive

  •   The positive impact of conservation action
    Science (IF 56.9) Pub Date : 2024-04-25
    Penny F. Langhammer, Joseph W. Bull, Jake E. Bicknell, Joseph L. Oakley, Mary H. Brown, Michael W. Bruford, Stuart H. M. Butchart, Jamie A. Carr, Don Church, Rosie Cooney, Simone Cutajar, Wendy Foden, Matthew N. Foster, Claude Gascon, Jonas Geldmann, Piero Genovesi, Michael Hoffmann, Jo Howard-McCombe, Tiffany Lewis, Nicholas B. W. Macfarlane, Zoe E. Melvin, Rossana Stoltz Merizalde, Meredith G. Morehouse

    Governments recently adopted new global targets to halt and reverse the loss of biodiversity. It is therefore crucial to understand the outcomes of conservation actions. We conducted a global meta-analysis of 186 studies (including 665 trials) that measured biodiversity over time and compared outcomes under conservation action with a suitable counterfactual of no action. We find that in two-thirds

  •   Vitamin D regulates microbiome-dependent cancer immunity
    Science (IF 56.9) Pub Date : 2024-04-25
    Evangelos Giampazolias, Mariana Pereira da Costa, Khiem C. Lam, Kok Haw Jonathan Lim, Ana Cardoso, Cécile Piot, Probir Chakravarty, Sonja Blasche, Swara Patel, Adi Biram, Tomas Castro-Dopico, Michael D. Buck, Richard R. Rodrigues, Gry Juul Poulsen, Susana A. Palma-Duran, Neil C. Rogers, Maria A. Koufaki, Carlos M. Minutti, Pengbo Wang, Alexander Vdovin, Bruno Frederico, Eleanor Childs, Sonia Lee, Ben

    A role for vitamin D in immune modulation and in cancer has been suggested. In this work, we report that mice with increased availability of vitamin D display greater immune-dependent resistance to transplantable cancers and augmented responses to checkpoint blockade immunotherapies. Similarly, in humans, vitamin D–induced genes correlate with improved responses to immune checkpoint inhibitor treatment

  •   The genetics of niche-specific behavioral tendencies in an adaptive radiation of cichlid fishes
    Science (IF 56.9) Pub Date : 2024-04-25
    Carolin Sommer-Trembo, M. Emília Santos, Bethan Clark, Marco Werner, Antoine Fages, Michael Matschiner, Simon Hornung, Fabrizia Ronco, Chantal Oliver, Cody Garcia, Patrick Tschopp, Milan Malinsky, Walter Salzburger

    Behavior is critical for animal survival and reproduction, and possibly for diversification and evolutionary radiation. However, the genetics behind adaptive variation in behavior are poorly understood. In this work, we examined a fundamental and widespread behavioral trait, exploratory behavior, in one of the largest adaptive radiations on Earth, the cichlid fishes of Lake Tanganyika. By integrating

  •   Nitrate reduction enables safer aryldiazonium chemistry
    Science (IF 56.9) Pub Date : 2024-04-25
    Javier Mateos, Tim Schulte, Deepak Behera, Markus Leutzsch, Ahmet Altun, Takuma Sato, Felix Waldbach, Alexander Schnegg, Frank Neese, Tobias Ritter

    Aryldiazonium salts remain a staple in organic synthesis and are still prepared largely in accord with the protocol developed in the 19th century. Because of the favorable reactivity that often cannot be achieved with other aryl(pseudo)halides, diazonium chemistry continues to grow. Facile extrusion of dinitrogen contributes to the desired reactivity but is also reason for safety concerns. Explosions

  •   Expansive discovery of chemically diverse structured macrocyclic oligoamides
    Science (IF 56.9) Pub Date : 2024-04-25
    Patrick J. Salveson, Adam P. Moyer, Meerit Y. Said, Gizem Gӧkçe, Xinting Li, Alex Kang, Hannah Nguyen, Asim K. Bera, Paul M. Levine, Gaurav Bhardwaj, David Baker

    Small macrocycles with four or fewer amino acids are among the most potent natural products known, but there is currently no way to systematically generate such compounds. We describe a computational method for identifying ordered macrocycles composed of alpha, beta, gamma, and 17 other amino acid backbone chemistries, which we used to predict 14.9 million closed cycles composed of >42,000 monomer

  •   Global trends and scenarios for terrestrial biodiversity and ecosystem services from 1900 to 2050
    Science (IF 56.9) Pub Date : 2024-04-25
    Henrique M. Pereira, Inês S. Martins, Isabel M. D. Rosa, HyeJin Kim, Paul Leadley, Alexander Popp, Detlef P. van Vuuren, George Hurtt, Luise Quoss, Almut Arneth, Daniele Baisero, Michel Bakkenes, Rebecca Chaplin-Kramer, Louise Chini, Moreno Di Marco, Simon Ferrier, Shinichiro Fujimori, Carlos A. Guerra, Michael Harfoot, Thomas D. Harwood, Tomoko Hasegawa, Vanessa Haverd, Petr Havlík, Stefanie Hellweg

    Based on an extensive model intercomparison, we assessed trends in biodiversity and ecosystem services from historical reconstructions and future scenarios of land-use and climate change. During the 20th century, biodiversity declined globally by 2 to 11%, as estimated by a range of indicators. Provisioning ecosystem services increased several fold, and regulating services decreased moderately. Going

Strohbach, Andrea Rukavina, Vincenth Brennsteiner, Kevin Ogilvie, Nara Marella, Katharina Kladnik, Rodolfo Ciuffa, Jaimeen D. Majmudar, S. Denise Field, Ariel Bensimon, Luca Ferrari, Evandro Ferrada, Amanda Ng, Zhechun Zhang, Gianluca Degliesposti, Andras Boeszoermenyi, Sascha Martens, Robert

    Chemical modulation of proteins enables a mechanistic understanding of biology and represents the foundation of most therapeutics. However, despite decades of research, 80% of the human proteome lacks functional ligands. Chemical proteomics has advanced fragment-based ligand discovery toward cellular systems, but throughput limitations have stymied the scalable identification of fragment-protein interactions

  •   Food perception promotes phosphorylation of MFFS131 and mitochondrial fragmentation in liver
    Science (IF 56.9) Pub Date : 2024-04-25
    Sinika Henschke, Hendrik Nolte, Judith Magoley, Tatjana Kleele, Claus Brandt, A. Christine Hausen, Claudia M. Wunderlich, Corinna A. Bauder, Philipp Aschauer, Suliana Manley, Thomas Langer, F. Thomas Wunderlich, Jens C. Brüning

    Liver mitochondria play a central role in metabolic adaptations to changing nutritional states, yet their dynamic regulation upon anticipated changes in nutrient availability has remained unaddressed. Here, we found that sensory food perception rapidly induced mitochondrial fragmentation in the liver through protein kinase B/AKT (AKT)–dependent phosphorylation of serine 131 of the mitochondrial fission

  •   Observation of a Chern insulator in crystalline ABCA-tetralayer graphene with spin-orbit coupling
    Science (IF 56.9) Pub Date : 2024-04-25
    Yating Sha, Jian Zheng, Kai Liu, Hong Du, Kenji Watanabe, Takashi Taniguchi, Jinfeng Jia, Zhiwen Shi, Ruidan Zhong, Guorui Chen

    Degeneracies in multilayer graphene, including spin, valley, and layer degrees of freedom, can be lifted by Coulomb interactions, resulting in rich broken-symmetry states. Here, we report a ferromagnetic state in charge-neutral ABCA-tetralayer graphene driven by proximity-induced spin-orbit coupling from adjacent tungsten diselenide. The ferromagnetic state is identified as a Chern insulator with a

    Science (IF 56.9) Pub Date : 2024-04-25
    Dana A. Opulente, Abigail Leavitt LaBella, Marie-Claire Harrison, John F. Wolters, Chao Liu, Yonglin Li, Jacek Kominek, Jacob L. Steenwyk, Hayley R. Stoneman, Jenna VanDenAvond, Caroline R. Miller, Quinn K. Langdon, Margarida Silva, Carla Gonçalves, Emily J. Ubbelohde, Yuanning Li, Kelly V. Buh, Martin Jarzyna, Max A. B. Haase, Carlos A. Rosa, Neža ČCadež, Diego Libkind, Jeremy H. DeVirgilio, Amanda

    Organisms exhibit extensive variation in ecological niche breadth, from very narrow (specialists) to very broad (generalists). Two general paradigms have been proposed to explain this variation: (i) trade-offs between performance efficiency and breadth and (ii) the joint influence of extrinsic (environmental) and intrinsic (genomic) factors. We assembled genomic, metabolic, and ecological data from

  •   Observation of current whirlpools in graphene at room temperature
    Science (IF 56.9) Pub Date : 2024-04-25
    Marius L. Palm, Chaoxin Ding, William S. Huxter, Takashi Taniguchi, Kenji Watanabe, Christian L. Degen

    Electron–electron interactions in high-mobility conductors can give rise to transport signatures resembling those described by classical hydrodynamics. Using a nanoscale scanning magnetometer, we imaged a distinctive hydrodynamic transport pattern—stationary current vortices—in a monolayer graphene device at room temperature. By measuring devices with increasing characteristic size, we observed the

  •   Sequence basis of transcription initiation in the human genome
    Science (IF 56.9) Pub Date : 2024-04-25
    Kseniia Dudnyk, Donghong Cai, Chenlai Shi, Jian Xu, Jian Zhou

    Transcription initiation is a process that is essential to ensuring the proper function of any gene, yet we still lack a unified understanding of sequence patterns and rules that explain most transcription start sites in the human genome. By predicting transcription initiation at base-pair resolution from sequences with a deep learning–inspired explainable model called Puffin, we show that a small

  •   Nickel binding enables isolation and reactivity of previously inaccessible 7-aza-2,3-indolynes
    Science (IF 56.9) Pub Date : 2024-04-25
    Jenna N. Humke, Roman G. Belli, Erin E. Plasek, Sallu S. Kargbo, Annabel Q. Ansel, Courtney C. Roberts

    N-Heteroaromatics are key elements of pharmaceuticals, agrochemicals, and materials. N-Heteroarynes provide a scaffold to build these essential molecules but are underused because five-membered N-heteroarynes have been largely inaccessible on account of the strain of a triple bond in that small of a ring. On the basis of principles of metal-ligand interactions that are foundational to organometallic

  •   Pre- and postnatal noise directly impairs avian development, with fitness consequences
    Science (IF 56.9) Pub Date : 2024-04-25
    Alizée Meillère, Katherine L. Buchanan, Justin R. Eastwood, Mylene M. Mariette

    Noise pollution is expanding at an unprecedented rate and is increasingly associated with impaired reproduction and development across taxa. However, whether noise sound waves are intrinsically harmful for developing young—or merely disturb parents—and the fitness consequences of early exposure remain unknown. Here, by only manipulating the offspring, we show that sole exposure to noise in early life

  •   Repair of CRISPR-guided RNA breaks enables site-specific RNA excision in human cells
    Science (IF 56.9) Pub Date : 2024-04-25
    Anna Nemudraia, Artem Nemudryi, Blake Wiedenheft

    Genome editing with CRISPR RNA-guided endonucleases generates DNA breaks that are resolved by cellular DNA repair machinery. However, analogous methods to manipulate RNA remain unavailable. Here, we show that site-specific RNA breaks generated with type III CRISPR complexes are repaired in human cells, and this repair can be used for programmable deletions in human transcripts to restore gene function

  •   Cleavage-independent activation of ancient eukaryotic gasdermins and structural mechanisms
    Science (IF 56.9) Pub Date : 2024-04-25
    Yueyue Li, Yanjie Hou, Qi Sun, Huan Zeng, Fanyi Meng, Xiang Tian, Qun He, Feng Shao, Jingjin Ding

    Gasdermins (GSDMs) are pore-forming proteins that execute pyroptosis for immune defense. GSDMs are two-domain proteins, activated by proteolytic removal of the inhibitory domain. Here we report two types of cleavage-independent GSDM activation. First, Tricho GSDM, a pore-forming-domain-only protein from the basal metazoan Trichoplax adhaerens , is a disulfides-linked autoinhibited dimer, activated

  •   Structural disorder determines capacitance in nanoporous carbons
    Science (IF 56.9) Pub Date : 2024-04-19
    Xinyu Liu, Dongxun Lyu, Céline Merlet, Matthew J. A. Leesmith, Xiao Hua, Zhen Xu, Clare P. Grey, Alexander C. Forse

    The difficulty in characterizing the complex structures of nanoporous carbon electrodes has led to a lack of clear design principles with which to improve supercapacitors. Pore size has long been considered the main lever to improve capacitance. However, our evaluation of a large series of commercial nanoporous carbons finds a lack of correlation between pore size and capacitance. Instead, nuclear

Foucher, Gwan Yeong Jung, Ilpyo Roh, Sangho Lee, Sun Ok Kim, Ji-Yun Moon, Seung-Il Kim, Sanggeun Bae, Xinyuan Zhang, Bo-In Park, Seunghwan Seo, Yimeng Li, Heechang Shin, Kate Reidy, Anh Tuan Hoang, Suresh Sundaram, Phuong Vuong, Chansoo Kim, Junyi Zhao, Jinyeon Hwang, Chuan Wang, Hyungil Choi, Dong-Hwan Kim, Jimin Kwon, Jin-Hong

    Electrostatic capacitors are foundational components of advanced electronics and high-power electrical systems owing to their ultrafast charging-discharging capability. Ferroelectric materials offer high maximum polarization, but high remnant polarization has hindered their effective deployment in energy storage applications. Previous methodologies have encountered problems because of the deteriorated

    Science (IF 56.9) Pub Date : 2024-04-19
    Daniel G. Streicker, Megan E. Griffiths, Rustom Antia, Laura Bergner, Peter Bowman, Maria Vitoria dos Santos de Moraes, Kevin Esvelt, Mike Famulare, Amy Gilbert, Biao He, Michael A. Jarvis, David A. Kennedy, Jennifer Kuzma, Carolyne Nasimiyu Wanyonyi, Christopher Remien, Tonie Rocke, Kyle Rosenke, Courtney Schreiner, Justin Sheen, David Simons, Ivet A. Yordanova, James J. Bull, Scott L. Nuismer

    Many emerging and reemerging pathogens originate from wildlife, but nearly all wild species are unreachable using conventional vaccination, which requires capture of and vaccine administration to individual animals. By enabling immunization at scales sufficient to interrupt pathogen transmission, transmissible vaccines (TVs) that spread themselves through wildlife populations by infectious processes

  •   Earth’s sinking surface
    Science (IF 56.9) Pub Date : 2024-04-19
    Robert J. Nicholls, Manoochehr Shirzaei

    Subsidence, the lowering of Earth’s land surface, is a widespread and sometimes dramatic process. Potentially 19% of the global population is at high risk of being affected by this process (1). Such sinking is caused by a range of natural or anthropogenic factors, including human-induced underground fluid withdrawal, which is generally considered the most important driver. However, present understanding

  •   Sentinels of the airways
    Science (IF 56.9) Pub Date : 2024-04-19
    Ziai Zhu, Xin Sun

    The respiratory tract is essential for breathing but is also important for detecting and responding to inhaled harmful (noxious) stimuli, such as pollutants, pathogens, water, and acid. Neuroendocrine cells (NECs)—rare epithelial cells that share characteristics with neurons—are an integral component of this sensory surveillance system (1). Although NECs have been proposed to act as airway sentinels

  •   Reprioritizing motivations in addiction
    Science (IF 56.9) Pub Date : 2024-04-19
    E. Zayra Millan, Gavan P. McNally

    Drug addictions are a leading global cause of health and economic burden, with opioids responsible for 80% of drug use–related deaths (1). Persistent drug use is accompanied by profound motivational reprioritization (2), with decision-making skewed toward drug use at the expense of other activities (3), often with little recognition of adverse consequences (4). These impacts owe, at least in part,

  •   Exposing belowground plant communication
    Science (IF 56.9) Pub Date : 2024-04-19
    Emilio Guerrieri, Sergio Rasmann

    Plants communicate through chemical signals, which convey information about environmental threats and resource availability, or even trigger defense mechanisms, allowing plants to coordinate responses and optimize their survival strategies (1). Plant communication encompasses both aboveground and belowground interactions. Aboveground, plants emit volatile organic compounds that are detected by the

  •   Isotopic evidence of long-lived volcanism on Io
    Science (IF 56.9) Pub Date : 2024-04-18
    Katherine de Kleer, Ery C. Hughes, Francis Nimmo, John Eiler, Amy E. Hofmann, Statia Luszcz-Cook, Kathy Mandt

    Jupiter’s moon Io hosts extensive volcanism, driven by tidal heating. The isotopic composition of Io’s inventory of volatile chemical elements, including sulfur and chlorine, reflects its outgassing and mass loss history, and thus records information about its evolution. We used millimeter observations of Io’s atmosphere to measure sulfur isotopes in gaseous SO 2 and SO, and chlorine isotopes in gaseous

  •   France needs a chief science adviser
    Science (IF 56.9) Pub Date : 2024-04-18
    Patrick Lemaire, François Massol

    France is at a crossroads, facing environmental and social challenges that are profoundly altering its society. Yet, the French government keeps prioritizing short-term political gains over long-term evidence-based planning for major transitions that France, like most countries, will undergo over the next 20 years. There is an urgent need for France to implement long-term science-informed policy-making

  •   Mapping twist-tuned multiband topology in bilayer WSe 2
    Science (IF 56.9) Pub Date : 2024-04-18
    Benjamin A. Foutty, Carlos R. Kometter, Trithep Devakul, Aidan P. Reddy, Kenji Watanabe, Takashi Taniguchi, Liang Fu, Benjamin E. Feldman

    Semiconductor moiré superlattices have been shown to host a wide array of interaction-driven ground states. However, twisted homobilayers have been difficult to study in the limit of large moiré wavelengths, where interactions are most dominant. In this study, we conducted local electronic compressibility measurements of twisted bilayer WSe 2 (tWSe 2 ) at small twist angles. We demonstrated multiple

    Science (IF 56.9) Pub Date : 2024-04-18
    Jean-Laurent Casanova, John D. MacMicking, Carl F. Nathan

    Infectious diseases continue to claim many lives. Prevention of morbidity and mortality from these diseases would benefit not just from new medicines and vaccines but also from a better understanding of what constitutes protective immunity. Among the major immune signals that mobilize host defense against infection is interferon- γ (IFN- γ ), a protein secreted by lymphocytes. Forty years ago, IFN-

Mittermaier, Henrike Planert, Sabine Grosser, Julia Onken, Katharina Faust, Thilo Kalbhenn, Matthias Simon, Helena Radbruch, Pawel Fidzinski, Dietmar Schmitz, Henrik Alle, Martin Holtkamp, Imre Vida, Benjamin F. Grewe, Jörg R. P. Geiger

    The computational capabilities of neuronal networks are fundamentally constrained by their specific connectivity. Previous studies of cortical connectivity have mostly been carried out in rodents; whether the principles established therein also apply to the evolutionarily expanded human cortex is unclear. We studied network properties within the human temporal cortex using samples obtained from brain

    Yujian Yao, Pingxia Zhang, Fei Sun, Wen Zhang, Meng Li, Gang Sha, Long Teng, Xianze Wang, Mingxin Huo, Ryan M. DuChanois, Tianchi Cao, Chanhee Boo, Xuan Zhang, Menachem Elimelech

    Thin-film composite reverse osmosis membranes have remained the gold standard technology for desalination and water purification for nearly half a century. Polyamide films offer excellent water permeability and salt rejection but also suffer from poor chlorine resistance, high fouling propensity, and low boron rejection. We addressed these issues by molecularly designing a polyester thin-film composite

Buda-Prejbeanu, Stéphane Auffret, Andrea Locatelli, Tevfik Onur Menteş, Stefania Pizzini, Pawan Kumar, Aurore Finco, Vincent Jacques, Gilles Gaudin, Olivier Boulle

    Magnetic skyrmions are topological magnetic textures that hold great promise as nanoscale bits of information in memory and logic devices. Although room-temperature ferromagnetic skyrmions and their current-induced manipulation have been demonstrated, their velocity has been limited to about 100 meters per second. In addition, their dynamics are perturbed by the skyrmion Hall effect, a motion transverse

    Science (IF 56.9) Pub Date : 2024-04-18
    Laura F. Seeholzer, David Julius

    Airway neuroendocrine (NE) cells have been proposed to serve as specialized sensory epithelial cells that modulate respiratory behavior by communicating with nearby nerve endings. However, their functional properties and physiological roles in the healthy lung, trachea, and larynx remain largely unknown. In this work, we show that murine NE cells in these compartments have distinct biophysical properties

  •   Drugs of abuse hijack a mesolimbic pathway that processes homeostatic need
    Science (IF 56.9) Pub Date : 2024-04-18
    Bowen Tan, Caleb J. Browne, Tobias Nöbauer, Alipasha Vaziri, Jeffrey M. Friedman, Eric J. Nestler

    Drugs of abuse are thought to promote addiction in part by “hijacking” brain reward systems, but the underlying mechanisms remain undefined. Using whole-brain FOS mapping and in vivo single-neuron calcium imaging, we found that drugs of abuse augment dopaminoceptive ensemble activity in the nucleus accumbens (NAc) and disorganize overlapping ensemble responses to natural rewards in a cell type–specific

  •   Reversal of quantized Hall drifts at noninteracting and interacting topological boundaries
    Science (IF 56.9) Pub Date : 2024-04-18
    Zijie Zhu, Marius Gächter, Anne-Sophie Walter, Konrad Viebahn, Tilman Esslinger

    The transport properties of gapless edge modes at boundaries between topologically distinct domains are of fundamental and technological importance. We experimentally studied long-distance quantized Hall drifts in a harmonically confined topological pump of ultracold fermionic atoms. We found that quantized drifts halt and reverse their direction when the atoms reach a critical slope of the confining

    Science (IF 56.9) Pub Date : 2024-04-12
    Min Zhang, Shun Lan, Bing B. Yang, Hao Pan, Yi Q. Liu, Qing H. Zhang, Jun L. Qi, Di Chen, Hang Su, Di Yi, Yue Y. Yang, Rui Wei, Hong D. Cai, Hao J. Han, Lin Gu, Ce-Wen Nan, Yuan-Hua Lin

    Ultrahigh–power-density multilayer ceramic capacitors (MLCCs) are critical components in electrical and electronic systems. However, the realization of a high energy density combined with a high efficiency is a major challenge for practical applications. We propose a high-entropy design in barium titanate (BaTiO3)–based lead-free MLCCs with polymorphic relaxor phase. This strategy effectively minimizes

    Epoxy resin thermosets (ERTs) are an important class of polymeric materials. However, owing to their highly cross-linked nature, they suffer from poor recyclability, which contributes to an unacceptable level of environmental pollution. There is a clear need for the design of inherently recyclable ERTs that are based on renewable resources. We present the synthesis and closed-loop recycling of a fully

    Single-phase body-centered cubic (bcc) refractory medium- or high-entropy alloys can retain compressive strength at elevated temperatures but suffer from extremely low tensile ductility and fracture toughness. We examined the strength and fracture toughness of a bcc refractory alloy, NbTaTiHf, from 77 to 1473 kelvin. This alloy’s behavior differed from that of comparable systems by having fracture

  •   Dating the Solar System’s giant planet orbital instability using enstatite meteorites
    Science (IF 56.9) Pub Date : 2024-04-16
    Chrysa Avdellidou, Marco Delbo’, David Nesvorný, Kevin J. Walsh, Alessandro Morbidelli

    The giant planets of the Solar System formed on initially compact orbits, which transitioned to the current wider configuration by means of an orbital instability. The timing of that instability is poorly constrained. In this work, we use dynamical simulations to demonstrate that the instability implanted planetesimal fragments from the terrestrial planet region into the asteroid main belt. We use

  •   Sex differences in tissue immunity
    Science (IF 56.9) Pub Date : 2024-04-12
    Franz Puttur, Clare M. Lloyd

    There are differences in the prevalence of inflammatory diseases between the sexes (sexual dimorphism), but the underlying mechanisms that regulate tissue immunity remain unclear. The interplay between multiple immune cells, structural cells, and tissue matrix proteins determines the outcome of tissue immunity. These interactions are regulated by intrinsic and extrinsic factors that calibrate the tone

  •   The nitroplast: A nitrogen-fixing organelle
    Science (IF 56.9) Pub Date : 2024-04-12
    Ramon Massana

    Eukaryotic cells are notably complex—for example, they have various organelles, which are membrane-bound structures with specific functions. Two of these organelles, mitochondria and chloroplasts, which function in respiration and photosynthesis, evolved from the integration of endosymbiotic bacteria to the eukaryotic cell (1). In marine systems, some nitrogen-fixing bacteria are endosymbionts of microalgae

  •   Designs where disorder prevails

    High-performance dielectric capacitors (which include insulating materials) play a crucial role in advanced electrical and electronic systems (1). In pulsed power systems, dielectric capacitors exhibit exceptionally high power density (rapid charging and discharging capabilities) and a prolonged operational lifetime, features that distinguish them from batteries and electrochemical capacitors (2).

  •   Closing the loop on thermoset plastic recycling
    Science (IF 56.9) Pub Date : 2024-04-12
    Bryce T. Nicholls, Brett P. Fors

    Globally, only 9% of plastics are recycled, and because of polymer degradation and mixed waste streams, their properties decline with each reuse cycle (1). Thermosets, a widely used class of plastics that maintain a permanent shape upon curing, are not recycled at all (2). In closed-loop recycling, a polymer can be processed into a new material without sacrificing properties, retaining the value of

  •   Molecular mechanism of actin filament elongation by formins
    Science (IF 56.9) Pub Date : 2024-04-11
    Wout Oosterheert, Micaela Boiero Sanders, Johanna Funk, Daniel Prumbaum, Stefan Raunser, Peter Bieling

    Formins control the assembly of actin filaments (F-actin) that drive cell morphogenesis and motility in eukaryotes. However, their molecular interaction with F-actin and their mechanism of action remain unclear. In this work, we present high-resolution cryo–electron microscopy structures of F-actin barbed ends bound by three distinct formins, revealing a common asymmetric formin conformation imposed

  •   Two inhibitory neuronal classes govern acquisition and recall of spinal sensorimotor adaptation
    Science (IF 56.9) Pub Date : 2024-04-11

    Spinal circuits are central to movement adaptation, yet the mechanisms within the spinal cord responsible for acquiring and retaining behavior upon experience remain unclear. Using a simple conditioning paradigm, we found that dorsal inhibitory neurons are indispensable for adapting protective limb-withdrawal behavior by regulating the transmission of a specific set of somatosensory information to

  •   Thin adhesive oil films lead to anomalously stable mixtures of water in oil
    Science (IF 56.9) Pub Date : 2024-04-11
    Claire Nannette, Jean Baudry, Anqi Chen, Yiqiao Song, Abdulwahed Shglabow, Nicolas Bremond, Damien Démoulin, Jamie Walters, David A. Weitz, Jérôme Bibette

    Oil and water can only be mixed by dispersing droplets of one fluid in the other. When two droplets approach one another, the thin film that separates them invariably becomes unstable, causing the droplets to coalesce. The only known way to avoid this instability is through addition of a third component, typically a surfactant, which stabilizes the thin film at its equilibrium thickness. We report

  •   Realization of an atomic quantum Hall system in four dimensions

    Modern condensed matter physics relies on the concept of topology to classify matter, from quantum Hall systems to topological insulators. Engineered systems, benefiting from synthetic dimensions, can potentially give access to topological states predicted in dimensions D > 3. We report the realization of an atomic quantum Hall system evolving in four dimensions (4D), with two spatial dimensions and

    Much is being made about the erosion of public trust in science. Surveys show a modest decline in the United States from a very high level of trust, but that is seen for other institutions as well. What is apparent from the surveys is that a better explanation of the nature of science—that it is revised as new data surface—would have a strong positive effect on public trust. Because scientists are

  •   Nitrogen-fixing organelle in a marine alga

    Symbiotic interactions were key to the evolution of chloroplast and mitochondria organelles, which mediate carbon and energy metabolism in eukaryotes. Biological nitrogen fixation, the reduction of abundant atmospheric nitrogen gas (N 2 ) to biologically available ammonia, is a key metabolic process performed exclusively by prokaryotes. Candidatus Atelocyanobacterium thalassa, or UCYN-A, is a metabolically

  •   Human telomere length is chromosome end–specific and conserved across individuals
    Science (IF 56.9) Pub Date : 2024-04-11

    Short telomeres cause age-related disease and long telomeres predispose to cancer; however, the mechanisms regulating telomere length are unclear. We developed a nanopore-based method, Telomere Profiling, to determine telomere length at nearly single nucleotide resolution. Mapping telomere reads to chromosome ends showed chromosome end–specific length distributions that could differ by more than six

    Therapeutic oligonucleotides are a powerful drug modality with the potential to treat many diseases. The rapidly growing number of therapies that have been approved and that are in advanced clinical trials will place unprecedented demands on our capacity to manufacture oligonucleotides at scale. Existing methods based on solid-phase phosphoramidite chemistry are limited by their scalability and sustainability
