  text: So-called spontaneous activity is a central hallmark of most nervous systems.
    Such non-causal firing is contrary to the tenet of spikes as a means of communication,
    and its purpose remains unclear. We propose that self-initiated firing can serve
    as a release valve to protect neurons from the toxic conditions arising in mitochondria
    from lower-than-baseline energy consumption. To demonstrate the viability of our
    hypothesis, we built a set of models that incorporate recent experimental results
    indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP),
    adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing.
    We explore the relationship of metabolic cost of spiking with its effect on the
    temporal patterning of spikes and reproduce experimentally observed changes in
    intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with
    ROS-modulated potassium channels. We also show that metabolic spiking homeostasis
    can produce indefinitely sustained avalanche dynamics in cortical circuits. Our
    theory can account for key features of neuronal activity observed in many studies
    ranging from ion channel function all the way to resting state dynamics. We finish
    with a set of experimental predictions that would confirm an integrated, crucial
    role for metabolically regulated spiking and firmly link metabolic homeostasis
    and neuronal function.

  text: As a crucial nitrogen source, nitrate (NO3−) is a key nutrient for plants.
    Accordingly, root systems adapt to maximize NO3− availability, a developmental
    regulation also involving the phytohormone auxin. Nonetheless, the molecular mechanisms
    underlying this regulation remain poorly understood. Here, we identify low-nitrate-resistant
    mutant (lonr) in Arabidopsis (Arabidopsis thaliana), whose root growth fails to
    adapt to low-NO3− conditions. lonr2 is defective in the high-affinity NO3− transporter
    NRT2.1. lonr2 (nrt2.1) mutants exhibit defects in polar auxin transport, and their
    low-NO3−-induced root phenotype depends on the PIN7 auxin exporter activity. NRT2.1
    directly associates with PIN7 and antagonizes PIN7-mediated auxin efflux depending
    on NO3− levels. These results reveal a mechanism by which NRT2.1 in response to
    NO3− limitation directly regulates auxin transport activity and, thus, root growth.
    This adaptive mechanism contributes to the root developmental plasticity to help
    plants cope with changes in NO3− availability.

  text: When Mendel’s work was rediscovered in 1900, and extended to establish classical
    genetics, it was initially seen in opposition to Darwin’s theory of evolution
    by natural selection on continuous variation, as represented by the biometric
    research program that was the foundation of quantitative genetics. As Fisher,
    Haldane, and Wright established a century ago, Mendelian inheritance is exactly
    what is needed for natural selection to work efficiently. Yet, the synthesis remains
    unfinished. We do not understand why sexual reproduction and a fair meiosis predominate
    in eukaryotes, or how far these are responsible for their diversity and complexity.
    Moreover, although quantitative geneticists have long known that adaptive variation
    is highly polygenic, and that this is essential for efficient selection, this
    is only now becoming appreciated by molecular biologists—and we still do not have
    a good framework for understanding polygenic variation or diffuse function.

  text: Plant cell growth responds rapidly to various stimuli, adapting architecture
    to environmental changes. Two major endogenous signals regulating growth are the
    phytohormone auxin and the secreted peptides rapid alkalinization factors (RALFs).
    Both trigger very rapid cellular responses and also exert long-term effects [Du
    et al., Annu. Rev. Plant Biol. 71, 379–402 (2020); Blackburn et al., Plant Physiol.
    182, 1657–1666 (2020)]. However, the way, in which these distinct signaling pathways
    converge to regulate growth, remains unknown. Here, using vertical confocal microscopy
    combined with a microfluidic chip, we addressed the mechanism of RALF action on
    growth. We observed correlation between RALF1-induced rapid Arabidopsis thaliana
    root growth inhibition and apoplast alkalinization during the initial phase of
    the response, and revealed that RALF1 reversibly inhibits primary root growth
    through apoplast alkalinization faster than within 1 min. This rapid apoplast
    alkalinization was the result of RALF1-induced net H+ influx and was mediated
    by the receptor FERONIA (FER). Furthermore, we investigated the cross-talk between
    RALF1 and the auxin signaling pathways during root growth regulation. The results
    showed that RALF-FER signaling triggered auxin signaling with a delay of approximately
    1 h by up-regulating auxin biosynthesis, thus contributing to sustained RALF1-induced
    growth inhibition. This biphasic RALF1 action on growth allows plants to respond
    rapidly to environmental stimuli and also reprogram growth and development in
    the long term.

  text: Primary nucleation is the fundamental event that initiates the conversion
    of proteins from their normal physiological forms into pathological amyloid aggregates
    associated with the onset and development of disorders including systemic amyloidosis,
    as well as the neurodegenerative conditions Alzheimer’s and Parkinson’s diseases.
    It has become apparent that the presence of surfaces can dramatically modulate
    nucleation. However, the underlying physicochemical parameters governing this
    process have been challenging to elucidate, with interfaces in some cases having
    been found to accelerate aggregation, while in others they can inhibit the kinetics
    of this process. Here we show through kinetic analysis that for three different
    fibril-forming proteins, interfaces affect the aggregation reaction mainly through
    modulating the primary nucleation step. Moreover, we show through direct measurements
    of the Gibbs free energy of adsorption, combined with theory and coarse-grained
    computer simulations, that overall nucleation rates are suppressed at high and
    at low surface interaction strengths but significantly enhanced at intermediate
    strengths, and we verify these regimes experimentally. Taken together, these results
    provide a quantitative description of the fundamental process which triggers amyloid
    formation and shed light on the key factors that control this process.

  text: 'Selection accumulates information in the genome—it guides stochastically
    evolving populations toward states (genotype frequencies) that would be unlikely
    under neutrality. This can be quantified as the Kullback–Leibler (KL) divergence
    between the actual distribution of genotype frequencies and the corresponding
    neutral distribution. First, we show that this population-level information sets
    an upper bound on the information at the level of genotype and phenotype, limiting
    how precisely they can be specified by selection. Next, we study how the accumulation
    and maintenance of information is limited by the cost of selection, measured as
    the genetic load or the relative fitness variance, both of which we connect to
    the control-theoretic KL cost of control. The information accumulation rate is
    upper bounded by the population size times the cost of selection. This bound is
    very general, and applies across models (Wright–Fisher, Moran, diffusion) and
    to arbitrary forms of selection, mutation, and recombination. Finally, the cost
    of maintaining information depends on how it is encoded: Specifying a single allele
    out of two is expensive, but one bit encoded among many weakly specified loci
    (as in a polygenic trait) is cheap.'

  text: Glaciers are key components of the mountain water towers of Asia and are vital
    for downstream domestic, agricultural, and industrial uses. The glacier mass loss
    rate over the southeastern Tibetan Plateau is among the highest in Asia and has
    accelerated in recent decades. This acceleration has been attributed to increased
    warming, but the mechanisms behind these glaciers’ high sensitivity to warming
    remain unclear, while the influence of changes in precipitation over the past
    decades is poorly quantified. Here, we reconstruct glacier mass changes and catchment
    runoff since 1975 at a benchmark glacier, Parlung No. 4, to shed light on the
    drivers of recent mass losses for the monsoonal, spring-accumulation glaciers
    of the Tibetan Plateau. Our modeling demonstrates how a temperature increase (mean
    of 0.39<jats:sup>∘</jats:sup>C ⋅dec<jats:sup>−1</jats:sup>since 1990) has accelerated
    mass loss rates by altering both the ablation and accumulation regimes in a complex
    manner. The majority of the post-2000 mass loss occurred during the monsoon months,
    caused by simultaneous decreases in the solid precipitation ratio (from 0.70 to
    0.56) and precipitation amount (–10%), leading to reduced monsoon accumulation
    (–26%). Higher solid precipitation in spring (+18%) during the last two decades
    was increasingly important in mitigating glacier mass loss by providing mass to
    the glacier and protecting it from melting in the early monsoon. With bare ice
    exposed to warmer temperatures for longer periods, icemelt and catchment discharge
    have unsustainably intensified since the start of the 21st century, raising concerns
    for long-term water supply and hazard occurrence in the region.

  text: 'The inverse problem of designing component interactions to target emergent
    structure is fundamental to numerous applications in biotechnology, materials
    science, and statistical physics. Equally important is the inverse problem of
    designing emergent kinetics, but this has received considerably less attention.
    Using recent advances in automatic differentiation, we show how kinetic pathways
    can be precisely designed by directly differentiating through statistical physics
    models, namely free energy calculations and molecular dynamics simulations. We
    consider two systems that are crucial to our understanding of structural self-assembly:
    bulk crystallization and small nanoclusters. In each case, we are able to assemble
    precise dynamical features. Using gradient information, we manipulate interactions
    among constituent particles to tune the rate at which these systems yield specific
    structures of interest. Moreover, we use this approach to learn nontrivial features
    about the high-dimensional design space, allowing us to accurately predict when
    multiple kinetic features can be simultaneously and independently controlled.
    These results provide a concrete and generalizable foundation for studying nonstructural
    self-assembly, including kinetic properties as well as other complex emergent
    properties, in a vast array of systems.'

  text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
    discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
    Current understanding states that the partition between surface adsorbed and dissolved
    lithium superoxide governs whether Li2O2 grows as a conformal surface film or
    larger particles, leading to low or high capacities, respectively. However, better
    understanding governing factors for Li2O2 packing density and capacity requires
    structural sensitive in situ metrologies. Here, we establish in situ small- and
    wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
    phase evolution with atomic to submicrometer resolution during cycling a custom-built
    in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
    rich quantitative structural information from complex multiphase systems. Surprisingly,
    we find that features are absent that would point at a Li2O2 surface film formed
    via two consecutive electron transfers, even in poorly solvating electrolytes
    thought to be prototypical for surface growth. All scattering data can be modeled
    by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
    Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
    and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
    particles, but there is no transition to an electronically passivating, conformal
    Li2O2 coating. Hence, mass transport of reactive species rather than electronic
    transport through a Li2O2 film limits the discharge capacity. Provided that species
    mobilities and carbon surface areas are high, this allows for high discharge capacities
    even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
    ought to be reconsidered.

  text: Turbulence generally arises in shear flows if velocities and hence, inertial
    forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit
    disordered motion even at vanishing inertia. Intermediate between these cases,
    a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed
    in a narrow Reynolds number interval. We here determine the origin of EIT in experiments
    and show that characteristic EIT structures can be detected across an unexpectedly
    wide range of parameters. Close to onset, a pattern of chevron-shaped streaks
    emerges in qualitative agreement with linear and weakly nonlinear theory. However,
    in experiments, the dynamics remain weakly chaotic, and the instability can be
    traced to far lower Reynolds numbers than permitted by theory. For increasing
    inertia, the flow undergoes a transformation to a wall mode composed of inclined
    near-wall streaks and shear layers. This mode persists to what is known as the
    “maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic
    flows across more than three orders of magnitude in Reynolds number.

  text: Unlike crystalline atomic and ionic solids, texture development due to crystallographically
    preferred growth in colloidal crystals is less studied. Here we investigate the
    underlying mechanisms of the texture evolution in an evaporation-induced colloidal
    assembly process through experiments, modeling, and theoretical analysis. In this
    widely used approach to obtain large-area colloidal crystals, the colloidal particles
    are driven to the meniscus via the evaporation of a solvent or matrix precursor
    solution where they close-pack to form a face-centered cubic colloidal assembly.
    Via two-dimensional large-area crystallographic mapping, we show that the initial
    crystal orientation is dominated by the interaction of particles with the meniscus,
    resulting in the expected coalignment of the close-packed direction with the local
    meniscus geometry. By combining with crystal structure analysis at a single-particle
    level, we further reveal that, at the later stage of self-assembly, however, the
    colloidal crystal undergoes a gradual rotation facilitated by geometrically necessary
    dislocations (GNDs) and achieves a large-area uniform crystallographic orientation
    with the close-packed direction perpendicular to the meniscus and parallel to
    the growth direction. Classical slip analysis, finite element-based mechanical
    simulation, computational colloidal assembly modeling, and continuum theory unequivocally
    show that these GNDs result from the tensile stress field along the meniscus direction
    due to the constrained shrinkage of the colloidal crystal during drying. The generation
    of GNDs with specific slip systems within individual grains leads to crystallographic
    rotation to accommodate the mechanical stress. The mechanistic understanding reported
    here can be utilized to control crystallographic features of colloidal assemblies,
    and may provide further insights into crystallographically preferred growth in
    synthetic, biological, and geological crystals.

  text: 'Parent-of-origin–dependent gene expression in mammals and flowering plants
    results from differing chromatin imprints (genomic imprinting) between maternally
    and paternally inherited alleles. Imprinted gene expression in the endosperm of
    seeds is associated with localized hypomethylation of maternally but not paternally
    inherited DNA, with certain small RNAs also displaying parent-of-origin–specific
    expression. To understand the evolution of imprinting mechanisms in Oryza sativa
    (rice), we analyzed imprinting divergence among four cultivars that span both
    japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted
    genes are imprinted across cultivars and enriched for functions in chromatin and
    transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted
    genes display divergent imprinting. Analyses of DNA methylation and small RNAs
    revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed
    DNA methylation, frequently overlap genes, and are imprinted four times more often
    than genes. However, imprinting divergence most often correlated with local DNA
    methylation epimutations (9 of 17 assessable loci), which were largely stable
    within subspecies. Small insertion/deletion events and transposable element insertions
    accompanied 4 of the 9 locally epimutated loci and associated with imprinting
    divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic
    variation occurred at key regulatory regions—the promoter and transcription start
    site of maternally biased genes, and the promoter and gene body of paternally
    biased genes. Our results reinforce models for the role of maternal-specific DNA
    hypomethylation in imprinting of both maternally and paternally biased genes,
    and highlight the role of transposition and epimutation in rice imprinting evolution.'

  text: Wound healing in plant tissues, consisting of rigid cell wall-encapsulated
    cells, represents a considerable challenge and occurs through largely unknown
    mechanisms distinct from those in animals. Owing to their inability to migrate,
    plant cells rely on targeted cell division and expansion to regenerate wounds.
    Strict coordination of these wound-induced responses is essential to ensure efficient,
    spatially restricted wound healing. Single-cell tracking by live imaging allowed
    us to gain mechanistic insight into the wound perception and coordination of wound
    responses after laser-based wounding in Arabidopsis root. We revealed a crucial
    contribution of the collapse of damaged cells in wound perception and detected
    an auxin increase specific to cells immediately adjacent to the wound. This localized
    auxin increase balances wound-induced cell expansion and restorative division
    rates in a dose-dependent manner, leading to tumorous overproliferation when the
    canonical TIR1 auxin signaling is disrupted. Auxin and wound-induced turgor pressure
    changes together also spatially define the activation of key components of regeneration,
    such as the transcription regulator ERF115. Our observations suggest that the
    wound signaling involves the sensing of collapse of damaged cells and a local
    auxin signaling activation to coordinate the downstream transcriptional responses
    in the immediate wound vicinity.

  text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
    family, which are activated at defined times and locations in a switch-like manner.
    While this switch is well understood for an individual protein, how regulatory
    networks produce intracellular activity patterns is currently not known. Here,
    we combine in vitro reconstitution experiments with computational modeling to
    study a minimal Rab5 activation network. We find that the molecular interactions
    in this system give rise to a positive feedback and bistable collective switching
    of Rab5. Furthermore, we find that switching near the critical point is intrinsically
    stochastic and provide evidence that controlling the inactive population of Rab5
    on the membrane can shape the network response. Notably, we demonstrate that collective
    switching can spread on the membrane surface as a traveling wave of Rab5 activation.
    Together, our findings reveal how biochemical signaling networks control vesicle
    trafficking pathways and how their nonequilibrium properties define the spatiotemporal
    organization of the cell.

  text: The actin cytoskeleton, a dynamic network of actin filaments and associated
    F-actin–binding proteins, is fundamentally important in eukaryotes. α-Actinins
    are major F-actin bundlers that are inhibited by Ca2+ in nonmuscle cells. Here
    we report the mechanism of Ca2+-mediated regulation of Entamoeba histolytica α-actinin-2
    (EhActn2) with features expected for the common ancestor of Entamoeba and higher
    eukaryotic α-actinins. Crystal structures of Ca2+-free and Ca2+-bound EhActn2
    reveal a calmodulin-like domain (CaMD) uniquely inserted within the rod domain.
    Integrative studies reveal an exceptionally high affinity of the EhActn2 CaMD
    for Ca2+, binding of which can only be regulated in the presence of physiological
    concentrations of Mg2+. Ca2+ binding triggers an increase in protein multidomain
    rigidity, reducing conformational flexibility of F-actin–binding domains via interdomain
    cross-talk and consequently inhibiting F-actin bundling. In vivo studies uncover
    that EhActn2 plays an important role in phagocytic cup formation and might constitute
    a new drug target for amoebic dysentery.

  text: Biological membranes can dramatically accelerate the aggregation of normally
    soluble protein molecules into amyloid fibrils and alter the fibril morphologies,
    yet the molecular mechanisms through which this accelerated nucleation takes place
    are not yet understood. Here, we develop a coarse-grained model to systematically
    explore the effect that the structural properties of the lipid membrane and the
    nature of protein–membrane interactions have on the nucleation rates of amyloid
    fibrils. We identify two physically distinct nucleation pathways—protein-rich
    and lipid-rich—and quantify how the membrane fluidity and protein–membrane affinity
    control the relative importance of those molecular pathways. We find that the
    membrane’s susceptibility to reshaping and being incorporated into the fibrillar
    aggregates is a key determinant of its ability to promote protein aggregation.
    We then characterize the rates and the free-energy profile associated with this
    heterogeneous nucleation process, in which the surface itself participates in
    the aggregate structure. Finally, we compare quantitatively our data to experiments
    on membrane-catalyzed amyloid aggregation of α-synuclein, a protein implicated
    in Parkinson’s disease that predominately nucleates on membranes. More generally,
    our results provide a framework for understanding macromolecular aggregation on
    lipid membranes in a broad biological and biotechnological context.

  text: Understanding the mechanism of action of compounds capable of inhibiting amyloid-fibril
    formation is critical to the development of potential therapeutics against protein-misfolding
    diseases. A fundamental challenge for progress is the range of possible target
    species and the disparate timescales involved, since the aggregating proteins
    are simultaneously the reactants, products, intermediates, and catalysts of the
    reaction. It is a complex problem, therefore, to choose the states of the aggregating
    proteins that should be bound by the compounds to achieve the most potent inhibition.
    We present here a comprehensive kinetic theory of amyloid-aggregation inhibition
    that reveals the fundamental thermodynamic and kinetic signatures characterizing
    effective inhibitors by identifying quantitative relationships between the aggregation
    and binding rate constants. These results provide general physical laws to guide
    the design and optimization of inhibitors of amyloid-fibril formation, revealing
    in particular the important role of on-rates in the binding of the inhibitors.

  text: Molecular mechanisms enabling the switching and maintenance of epigenetic
    states are not fully understood. Distinct histone modifications are often associated
    with ON/OFF epigenetic states, but how these states are stably maintained through
    DNA replication, yet in certain situations switch from one to another remains
    unclear. Here, we address this problem through identification of Arabidopsis INCURVATA11
    (ICU11) as a Polycomb Repressive Complex 2 accessory protein. ICU11 robustly immunoprecipitated
    in vivo with PRC2 core components and the accessory proteins, EMBRYONIC FLOWER
    1 (EMF1), LIKE HETEROCHROMATIN PROTEIN1 (LHP1), and TELOMERE_REPEAT_BINDING FACTORS
    (TRBs). ICU11 encodes a 2-oxoglutarate-dependent dioxygenase, an activity associated
    with histone demethylation in other organisms, and mutant plants show defects
    in multiple aspects of the Arabidopsis epigenome. To investigate its primary molecular
    function we identified the Arabidopsis FLOWERING LOCUS C (FLC) as a direct target
    and found icu11 disrupted the cold-induced, Polycomb-mediated silencing underlying
    vernalization. icu11 prevented reduction in H3K36me3 levels normally seen during
    the early cold phase, supporting a role for ICU11 in H3K36me3 demethylation. This
    was coincident with an attenuation of H3K27me3 at the internal nucleation site
    in FLC, and reduction in H3K27me3 levels across the body of the gene after plants
    were returned to the warm. Thus, ICU11 is required for the cold-induced epigenetic
    switching between the mutually exclusive chromatin states at FLC, from the active
    H3K36me3 state to the silenced H3K27me3 state. These data support the importance
    of physical coupling of histone modification activities to promote epigenetic
    switching between opposing chromatin states.

  text: Plasmodesmata (PD) are plant-specific membrane-lined channels that create
    cytoplasmic and membrane continuities between adjacent cells, thereby facilitating
    cell–cell communication and virus movement. Plant cells have evolved diverse mechanisms
    to regulate PD plasticity in response to numerous environmental stimuli. In particular,
    during defense against plant pathogens, the defense hormone, salicylic acid (SA),
    plays a crucial role in the regulation of PD permeability in a callose-dependent
    manner. Here, we uncover a mechanism by which plants restrict the spreading of
    virus and PD cargoes using SA signaling by increasing lipid order and closure
    of PD. We showed that exogenous SA application triggered the compartmentalization
    of lipid raft nanodomains through a modulation of the lipid raft-regulatory protein,
    Remorin (REM). Genetic studies, superresolution imaging, and transmission electron
    microscopy observation together demonstrated that Arabidopsis REM1.2 and REM1.3
    are crucial for plasma membrane nanodomain assembly to control PD aperture and
    functionality. In addition, we also found that a 14-3-3 epsilon protein modulates
    REM clustering and membrane nanodomain compartmentalization through its direct
    interaction with REM proteins. This study unveils a molecular mechanism by which
    the key plant defense hormone, SA, triggers membrane lipid nanodomain reorganization,
    thereby regulating PD closure to impede virus spreading.

  text: Chiral molecules interact and react differently with other chiral objects,
    depending on their handedness. Therefore, it is essential to understand and ultimately
    control the evolution of molecular chirality during chemical reactions. Although
    highly sophisticated techniques for the controlled synthesis of chiral molecules
    have been developed, the observation of chirality on the natural femtosecond time
    scale of a chemical reaction has so far remained out of reach in the gas phase.
    Here, we demonstrate a general experimental technique, based on high-harmonic
    generation in tailored laser fields, and apply it to probe the time evolution
    of molecular chirality during the photodissociation of 2-iodobutane. These measurements
    show a change in sign and a pronounced increase in the magnitude of the chiral
    response over the first 100 fs, followed by its decay within less than 500 fs,
    revealing the photodissociation to achiral products. The observed time evolution
    is explained in terms of the variation of the electric and magnetic transition-dipole
    moments between the lowest electronic states of the cation as a function of the
    reaction coordinate. These results open the path to investigations of the chirality
    of molecular-reaction pathways, light-induced chirality in chemical processes,
    and the control of molecular chirality through tailored laser pulses.
