  text: Structural and functional differences between brain hemispheres are a common
    feature of animal nervous systems with reduced bilateral asymmetry often linked
    to impaired cognitive performance. How neuronal left-right asymmetry is initiated
    and integrated into a bilaterally symmetrical ground pattern is poorly understood.
    Here, we show that the directional asymmetry of a Drosophila central brain circuit
    originates from axonal interactions of two types of bilateral pioneer neurons.
    Subsequent recruitment of neighboring neurons into the asymmetric neuropil primordium
    results in hemisphere-specific microcircuits. Circuit lateralization requires
    dynamic expression of the cell adhesion molecule Fasciclin 2 to maintain structural
    plasticity in axonal remodeling. Reduced circuit asymmetry following cell type–specific
    Fasciclin 2 manipulation affects adult brain function. These results reveal an
    unexpected degree of developmental plasticity of late-born Drosophila neurons
    in the formation of a circuit node via the lateralized recruitment of symmetric
    circuit components.

  text: On October 4, 2023, a proglacial lake named the South Lhonak lake was the
    source of a catastrophic Glacier Lake Outburst Flood (GLOF) in the Teesta river
    basin area, resulting in 24 fatalities and leaving over 70 persons missing. The
    GLOF also destroyed 13 bridges and a major hydropower plant in the Chungthang
    region. Over 60,000 individuals in four districts of Sikkim were impacted by this
    GLOF event. This study examines the factors that led to the GLOF event. Our study
    shows that the cause of this GLOF was initiated by a landslide, that dumped a
    substantial amount (~ 38.31 million m3) of debris into the South Lhonak Lake.
    Furthermore, the glacier that was connected to the lake, lost a big chunk of ice
    mass (~ 7 million m3) due to calving. The combination of these two processes led
    to the collapse of the left lateral moraine that consequently generated flood
    waves which breached the terminal moraine dam of the lake. We recommend monitoring
    land subsidence and calving events for large proglacial lakes to prevent the disastrous
    consequences of such GLOFs in the future.

  text: 'JWST’s “little red dots” (LRDs) are increasingly interpreted as active galactic
    nuclei (AGN) obscured by dense thermalized gas rather than dust as evidenced by
    their X-ray weakness, blackbody-like continua, and Balmer line profiles. Key questions
    are how LRDs connect to standard UV-luminous AGN, whether transitional phases
    exist, and whether they are observable. We present the “X-ray dot” (XRD), a compact
    source at z = 3.28 observed by the NIRSpec Wide Guaranteed Time Observation survey.
    The XRD exhibits LRD hallmarks: a blackbody-like (Teff ≃ 6400 K) red continuum,
    a faint but blue rest-UV excess, falling mid-IR emission, and broad Balmer lines
    (FWHM ∼ 2700–3200 km s−1). Unlike LRDs, however, it is remarkably X-ray luminous
    (L2−10 keV = 1044.18 erg s−1) and has a continuum inflection that is blueward
    of the Balmer limit. We find that the red rest-optical and blue mid-IR continuum
    cannot be reproduced by standard dust-attenuated AGN models without invoking extremely
    steep extinction curves, nor can the weak mid-IR emission be reconciled with well-established
    X-ray–torus scaling relations. We therefore consider an alternative scenario:
    the XRD may be an LRD in transition, where the gas envelope dominates the optical
    continuum but optically thin sight lines allow X-rays to escape. The XRD may thus
    provide a physical link between LRDs and standard AGN, offering direct evidence
    that LRDs are powered by supermassive black holes and providing insight into their
    accretion properties.'

  text: "Early results from JWST suggest that Epoch of Reionization (EoR) galaxies
    produce copious ionizing photons, which, if they escape efficiently, could cause
    reionization to occur too early. We study this problem using JWST imaging and
    prism spectroscopy for 412 galaxies at 4.5 < z < 9.0. We fit these data simultaneously
    with stellar population and nebular emission models that include a parameter for
    the fraction of ionizing photons that escape the galaxy, fesc. We find that the
    ionization production efficiency, ξion = Q(H0)/LUV, increases with redshift and
    decreasing UV luminosity, but shows significant scatter, (log ion z, MUV) 0.3
    dex. The inferred escape fractions averaged over the population are low, ranging
    from〈fesc〉 ≃ 2.6% ± 1.4% at 6 < z < 9 to 6.5% ± 2.2% at 4.5 < z < 6, with weak
    or no indication of evolution with redshift. This implies that in our models most
    of the ionizing photons need to be absorbed to account for the nebular emission.
    We compute the impact of our results on reionization, including the distributions
    for ξion and fesc, and the evolution and uncertainty of the UV luminosity function.
    Considering galaxies brighter than MUV < −16 mag would produce an intergalactic
    medium hydrogen-ionized fraction of xe = 0.5 at 5.3 < z < 5.8, possibly too late
    compared to constraints from from quasistellar\r\nobject (QSO) sight lines. Including
    fainter galaxies, MUV < −14 mag, we obtain xe = 0.5 at 6.0 < z < 8.1, fully consistent
    with QSO and cosmic microwave background data. This implies that EoR galaxies
    produce plenty of ionizing photons, but that these do not efficiently escape.
    This may be a result of high gas column densities combined with burstier star
    formation histories, which limit the time massive stars are able to clear channels
    through the gas for ionizing photons to escape."

  text: 'Background: Low-volume trapping columns are essential for sample enrichment,
    desalting, and injection profile focusing on nano-LC–MS-based proteomics. They
    enable higher sample loading, improve chromatographic performance, and protect
    the analytical column by removing salts and contaminants. Recently, monolithic
    trap columns with micropillar architecture have emerged as alternatives to conventionally
    packed traps. This study compares the performance of a packed and a micropillar
    monolithic trap column for the analysis of tryptic peptides. Methods: A tryptic
    digest of HeLa cell lysate was analyzed under identical LC–MS conditions using
    both trap types. Peptides were detected at 214 nm and analyzed by nano-ESI on
    a Q Exactive Plus Orbitrap. Data were searched against the human UniProt database
    (February 2023) using FragPipe v20.0, and statistical evaluation of MaxLFQ intensities
    was performed in Perseus using Welch’s t-test and clustering analysis. Results:
    Over 2500 proteins were identified with both setups. The packed trap column yielded
    more total peptides, particularly those with post-translational modifications
    and higher hydrophilicity, whereas the monolithic column favored peptides of intermediate
    hydrophobicity. Chromatographic profiles confirmed a slight reduction in the trapping
    efficiency of hydrophilic peptides by the monolithic trap. Conclusions: Trap column
    design significantly influences peptide recovery and proteome coverage.'

  text: Supermassive black hole binary (SMBHB) systems are expected to form as a consequence
    of galaxy mergers. At subparsec separations, SMBHBs can be identified as quasars
    with periodic variability, with previous periodicity searches uncovering significant
    candidates. However, these searches focused primarily on sinusoidal signals, while
    theoretical models and hydrodynamical simulations predict that binaries produce
    more complex non-sinusoidal pulse shapes. Here we examine the efficacy of the
    Lomb–Scargle periodogram (LSP; one of the most popular tools for periodicity searches
    in unevenly sampled lightcurves) to detect periodicities with a sawtooth shape
    mimicking results of hydrodynamical simulations. We simulate idealized well-sampled
    lightcurves, lightcurves that mimic the data in the Palomar Transient Factory
    (PTF) analyzed in M. Charisi et al. (2016), and lightcurves that resemble our
    expectations for single-band data in the upcoming Legacy Survey of Space and Time
    (LSST) of the Rubin Observatory. We approximate quasar variability with a damped
    random walk (DRW) model, inject sinusoidal and sawtooth pulse shapes, and assess
    their statistical significance. We find that in the presence of red noise, the
    LSP detects a relatively low fraction of the sinusoidal signals (∼45%, ∼24%, and
    ∼23%, in the PTF-like, idealized, and LSST-like lightcurves, respectively). The
    fraction is significantly reduced for sawtooth periodicity (with only ∼9% in PTF-like
    and ∼1% in idealized and LSST-like lightcurves). These low recovery rates imply
    that previous searches have missed the large majority of binaries. They also have
    significant implications for the detection of SMBHBs in upcoming LSST necessitating
    the development of advanced tools that go beyond the simple LSP.

  text: GW231123 represents the most massive binary–black hole merger detected to
    date, lying firmly within, or even above, the pair-instability mass gap. The component
    spins are both exceptionally high (a1 = 0.90 +0.10/-0.19, a2 = 0.80 +0.20/-0.51),
    which is difficult to explain with repeated mergers. Here we show that the black
    hole spin vectors are closely aligned with each other while significantly tilted
    relative to the binary’s orbital angular momentum, pointing to a common accretion-driven
    origin. We examine astrophysical formation channels capable of producing near-equal,
    high-mass, and mutually aligned spins consistent with GW231123—particularly binaries
    embedded in AGN disks and Population III remnants, which grew via coherent misaligned
    gas accretion. We further argue that other high-mass, high-spin events, e.g.,
    GW190521, may share a similar evolutionary pathway. These findings underscore
    the critical role of sustained, coherent accretion in shaping the most extreme
    black hole binaries.

  text: Be stars are rapidly rotating main-sequence stars that play a crucial role
    in understanding stellar evolution and binary interactions. In this Letter, we
    propose a new formation scenario for black hole (BH) + Be star binaries (hereafter
    BHBe binaries), where the Be star is produced through the wind Roche lobe overflow
    (WRLOF) mechanism. Our analysis is based on numerical simulations of the WRLOF
    process in massive binaries, building on recent theoretical work. We demonstrate
    that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions
    on stellar wind velocities. Using rapid binary population synthesis, we estimate
    the population of such systems in the Milky Way, predicting ∼1800−3200 currently
    existing BHBe binaries originating from the WRLOF channel. These systems are characterized
    by high eccentricities and exceptionally wide orbits, with typical orbital periods
    exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their
    long orbital separations, these BHBe binaries are promising targets for future
    detection via astrometric and interferometric observations.

  text: New populations of red active galactic nuclei (known as “little red dots”)
    discovered by JWST exhibit remarkable spectral energy distributions. Leveraging
    X-ray through far-infrared observations of two of the most luminous known little
    red dots, we directly measure their bolometric luminosities. We find evidence
    that more than half of the bolometric luminosity likely emerges in the rest-frame
    optical, with Lbol/L5100 = 5, roughly half the value for “standard” active galactic
    nuclei. Meanwhile, the X-ray emitting corona, UV-emitting blackbody, and reprocessed
    mid to far-infrared emission are all considerably subdominant, assuming that the
    far-infrared luminosity is well below current measured limits. We present new
    bolometric corrections that dramatically lower inferred bolometric luminosities
    by a factor of 10 compared to published values in the literature. These bolometric
    corrections are in accord with expectations from models in which gas absorption
    and reprocessing are responsible for the red rest-frame optical colors of little
    red dots. We discuss how this lowered luminosity scale suggests a lower mass scale
    for the population by at least an order of magnitude (e.g., ∼105–107 M⊙ black
    holes, and ∼108 M⊙ galaxies), alleviating tensions with clustering, overmassive
    black holes, and the integrated black hole mass density in the Universe.

  text: Male germline development in plants is highly sensitive to heat stress, with
    elevated temperatures frequently impairing male fertility and consequently reducing
    seed production. Indeed, recent global warming has decreased major crop yields,
    emphasizing the urgent need to elucidate the molecular and cellular mechanisms
    underlying heat-induced male sterility. This review synthesizes current knowledge
    on how heat stress disrupts microsporogenesis and microgametogenesis, and how
    plants counteract these stresses through diverse thermotolerance mechanisms. We
    emphasize temperature-sensitive processes, including meiotic progression in male
    germ cells, programmed cell death of somatic tapetal nurse cells, and post-meiotic
    pollen tube development. We further discuss how epigenetic regulators enhance
    thermotolerance by reprogramming DNA methylation landscapes and modulating histone
    variant distribution. Finally, we propose future directions aimed at understanding
    the mechanisms of reproductive thermotolerance from the epigenetic perspective.

  text: Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider
    uncertainties in transition probabilities by defining a set of possible transition
    functions. An objective is a set of runs (or infinite trajectories) of the RMDP,
    and the value for an objective is the maximal probability that the agent can guarantee
    against the adversarial environment. We consider (a) reachability objectives,
    where given a target set of states, the goal is to eventually arrive at one of
    them; and (b) parity objectives, which are a canonical representation for ω-regular
    objectives. The qualitative analysis problem asks whether the objective can be
    ensured with probability 1. In this work, we study the qualitative problem for
    reachability and parity objectives on RMDPs without making any assumption over
    the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are
    twofold. We first present efficient algorithms with oracle access to uncertainty
    sets that solve qualitative problems of reachability and parity objectives. We
    then report experimental results demonstrating the effectiveness of our oracle-based
    approach on classical RMDP examples from the literature scaling up to thousands
    of states.

  text: "In this paper, we consider the big algebra recently introduced by Hausel
    for the GLn-action on the coordinate ring of the matrix space Mat(n,r). In particular,
    we obtain explicit formulas for the big algebra generators in terms of differential
    operators with polynomial coefficients. We show that big algebras in type A are
    commutative and relate them to the Bethe subalgebra in the Yangian Y(gln). We
    apply these results to big algebras of symmetric powers of the standard representation
    of GLn.\r\n."

  text: "We develop a new algorithmic framework for designing approximation algorithms
    for cut-based optimization problems on capacitated undirected graphs that undergo
    edge insertions and deletions. Specifically, our framework dynamically maintains
    a variant of the hierarchical \U0001D457-tree decomposition of [Madry FOCS’10],
    achieving a poly-logarithmic approximation factor to the graph’s cut structure
    and supporting edge updates in \U0001D442⁡(\U0001D45B\U0001D700) amortized update
    time, for any arbitrarily small constant \U0001D700 ∈(0,1).\r\nConsequently, we
    obtain new trade-offs between approximation and update/query time for fundamental
    cut-based optimization problems in the fully dynamic setting, including all-pairs
    minimum cuts, sparsest cut, multi-way cut, and multi-cut. For the last three problems,
    these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic
    approximation in sub-linear time per operation.\r\nThe main technical ingredient
    behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle
    vertex splits with low recourse. This is achieved by white-boxing the dynamic
    cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing,
    together with new structural insights about the maintenance of these forests under
    vertex splits. Given the versatility of cut sparsification in both the static
    and dynamic graph algorithms literature, we believe this construction may be of
    independent interest."

  text: "We present an exact fully-dynamic minimum cut algorithm that runs in \U0001D45B\U0001D45C⁡(1)
    deterministic update time when the minimum cut size is at most 2Θ⁡(log3/4−\U0001D450⁡\U0001D45B)
    for any \U0001D450 >0, improving on the previous algorithm of Jin, Sun, and Thorup
    (SODA 2024) whose minimum cut size limit is (log⁡\U0001D45B)\U0001D45C⁡(1). Combined
    with graph sparsification, we obtain the first (1 +\U0001D716)-approximate fully-dynamic
    minimum cut algorithm on weighted graphs, for any \U0001D716 ≥2−Θ⁡(log3/4−\U0001D450⁡\U0001D45B),

  text: 'Swimming bacteria move through a fluid by actuating their moving body parts.
    They are force-free and can be described as hydrodynamic force dipoles: pushers
    or pullers. This modelling description is broadly used in biological physics and
    active matter research, and it has successfully predicted, for example, the superfluid
    behaviour of suspensions of pushers or the bend instability and emergence of turbulent
    flows in active nematics. However, this description accounts only for the translational
    motion of the swimming body and neglects the effects of hydrodynamic torque dipoles,
    which are relevant to bacteria with rotary motor-driven flagella, such as swimming
    Escherichia coli. Here we show that the torque dipole of confined swimming E.
    coli can power the persistent rotation of symmetric discs. The torque dipole leads
    to a traction force on the discs, an additive mechanism that is both contactless
    and independent of the orientation of the bacteria. Our results indicate that
    the torque dipole of swimming E. coli is notable in confined geometries, which
    is relevant to bacterial transport through porous materials, biofilms and the
    development of chiral fluids.'

  text: "The initial–final mass relation (IFMR) links a star’s birth mass to the mass
    of its white dwarf (WD) remnant, providing key constraints on stellar evolution.
    Open clusters offer the most straightforward way to empirically determine the
    IFMR, as their well-defined ages allow for direct progenitor lifetime estimates.
    We construct the most comprehensive open cluster WD IFMR to date by combining
    new spectroscopy of 22 WDs with an extensive literature review of WDs with strong
    cluster associations. To minimize systematics, we restrict our analysis to spectroscopically
    confirmed hydrogen-atmosphere (DA) WDs consistent with single-stellar origins.
    We separately analyze a subset with reliable Gaia-based astrometric membership
    assessments, as well as a full sample that adds WDs with strong cluster associations
    whose membership cannot be reliably assessed with Gaia. The Gaia-based sample
    includes 69 spectroscopically confirmed DA WDs, more than doubling the sample
    size of previous Gaia-based open cluster IFMRs. The full sample, which includes
    53 additional literature WDs,\r\nincreases the total number of cluster WDs by
    over 50% relative to earlier works. We provide functional forms for both the Gaia-based
    and full-sample IFMRs. The Gaia-based result useful for Mi � 2.67 M⊙ is Mf = [0.179
    0.100H (Mi 3.84 M )] × (Mi 3.84 M ) + 0.628 M , where H(x) is the Heaviside step
    function. Comparing our IFMR to recent literature, we identify significant deviations
    from best-fit IFMRs derived from both Gaia-based volume-limited samples of field
    WDs and double WD binaries, with the largest discrepancy occurring for initial
    masses of about 5 M⊙."

  text: Quantum control of the many-body wavefunction is a central challenge in quantum
    materials research, as it could yield a precise control knob to manipulate emergent
    phenomena. Floquet engineering, the coherent dressing of quantum states with periodic
    non-resonant optical fields, has become an important strategy for quantum control.
    Most applications to solid-state systems have targeted weakly interacting or single-ion
    states, leaving the manipulation of many-body wavefunctions largely unexplored.
    Here we use Floquet engineering to achieve quantum control of a strongly correlated
    Hubbard exciton in the one-dimensional Mott insulator Sr2CuO3. A non-resonant
    mid-infrared optical field coherently dresses the exciton wavefunction, driving
    its rotation between bright and dark states. We use resonant third-harmonic generation
    to quantify ultrafast π/2 rotations on the Bloch sphere spanned by these exciton
    states. Our work advances the quest towards programmable control of correlated
    states and exciton-based quantum sensing.

  text: In calculus, l'Hopital's rule provides a simple way to evaluate the limits
    of quotient functions when both the numerator and denominator vanish. But what
    happens when we move beyond real functions on a real interval? In this article,
    we study when the quotient of two complex-valued functions in higher dimension
    can be defined continuously at the points where both functions vanish. Surprisingly,
    the answer is far subtler than in the real-valued setting. We provide a complete
    characterization for the continuity of the quotient function. We also point out
    why extending this result to smoother quotients remains an intriguing challenge.

  text: We present symplectic structures on the shape space of unparameterized space
    curves that generalize the classical Marsden–Weinstein structure. Our method integrates
    the Liouville 1-form of the Marsden–Weinstein structure with Riemannian structures
    that have been introduced in mathematical shape analysis. We also derive Hamiltonian
    vector fields for several classical Hamiltonian functions with respect to these
    new symplectic structures.

  text: The paraventricular hypothalamus (PVH) controls behavioral and physiologic
    processes, including appetite, social behavior, autonomic outflow, and pituitary
    hormone secretion. However, molecular markers for centrally projecting PVH neuron
    populations remain largely undefined, and a complete census of PVH cell types
    has not been established. Therefore, we performed extensive single-cell/nucleus
    RNA sequencing to catalog PVH neuron subtypes and multiplexed error-robust fluorescence
    in situ hybridization (MERFISH) to map them spatially. Our spatial transcriptomic
    atlas resolves 26 Sim1+ and 29 GABAergic neuron populations from the PVH and surrounding
    areas. Additionally, projection-based profiling identified neurons that project
    to the parabrachial region (PB) and spinal cord, helping to determine PVH populations
    that regulate satiety and sympathetic nervous system activity, respectively. Notably,
    activation of PB-projecting PVH neurons expressing Brs3 reduces food intake, and
    silencing them causes obesity. Together, this atlas contributes high-resolution
    PVH spatial and circuit-based gene expression profiles, representing a valuable
    resource for the field of homeostasis.
