  text: It is predicted that half or more of all cataclysmic variables (CVs) should
    have evolved past the period minimum and now exist as so-called period bouncers
    where a white dwarf should be accreting from a Roche lobe filling substellar companion.
    However, this prediction stands in stark contrast to observations, where only
    a few per cent of CVs are found in this evolutionary phase. A potential solution
    to this discrepancy is that a magnetic field emerges from within the white dwarf
    after the system has reached the period minimum. The transfer of angular momentum
    from the spin of the white dwarf into the orbit then pushes the two stars apart,
    detaching them for potentially billions of years. Here we present the discovery
    of ZTF J021804.16+071152.93, a detached 0.69 +- 0.01 M⁠, 19 MG magnetic white
    dwarf plus 37 +- 5MJup brown dwarf binary with an orbital period of 1.7 h. The
    kinematics of the system indicate that it is a high probability member of the
    Galactic thick disc. However, this strongly disagrees with the much younger age
    of the system obtained from the white dwarf parameters, implying that the system
    may have been accreting in the past. This system is therefore consistent with
    having detached as a result of the emergence of the magnetic field of the white
    dwarf when the system was still mass transferring, and may represent the ultimate
    fate for many (perhaps even most) CVs.

  text: "Given a set A of n points (vertices) in general position in the plane, the
    complete geometric graph \r\nKn[A] consists of all (n2) segments (edges) between
    the elements of A. It is known that the edge set of every complete geometric graph
    on n vertices can be partitioned into O(n3∕2) crossing-free paths (or matchings).
    We strengthen this result under various additional assumptions on the point set.
    In particular, we prove that for a set A of n randomly selected points, uniformly
    distributed in [0,1]2, with probability tending to 1 as n→∞, the edge set of Kn[A]
    can be covered by O(nlogn) crossing-free paths and by O(n√logn) crossing-free
    matchings. On the other hand, we construct n-element point sets such that covering
    the edge set of Kn[A] requires a quadratic number of monotone paths."

  text: 'Phase singularities—points carrying quantized topological charge—are universal
    features found across diverse wave systems from superfluids and superconductors
    to acoustic and optical fields1,2,3,4. Ensembles of these singularities exhibit
    distance correlations resembling particles in liquids5,6,7,8, extensively studied
    for their role in exotic material phases9,10,11. By contrast, the full correlations
    in phase space that govern the system evolution have remained unexplored and experimentally
    inaccessible. Here we directly measure the ultrafast dynamics of optical singularity
    ensembles, capturing their full phase-space correlations, presenting the joint
    distance–velocity distribution. Our observations show a breakdown of the particle-singularity
    analogy12: phase singularities accelerate towards formally divergent velocities
    in the moment before annihilation7,13,14, indicated by measurements of velocities
    exceeding the speed of light. These apparent superluminal velocities are paradoxically
    amplified by the slow group velocity of hyperbolic phonon polaritons in our material
    platform, hexagonal boron nitride membranes15,16,17,18,19. We demonstrate these
    phenomena using combined hardware and algorithmic advances in ultrafast electron
    microscopy18,20,21,22,23,24,25, achieving spatial and temporal resolutions, each
    an order of magnitude below the polaritonic wavelength and cycle period. Our findings
    deepen our understanding of phase singularities and their universality, enabling
    to probe topological defect dynamics at previously unattainable timescales.'

  text: 'In a warming world of glacier changes, the scientific community has dedicated
    increasing attention to debris-covered glaciers and their response to climate.
    A variety of models with distinct complexity and data requirements have been developed
    and widely used to simulate melt under debris at different sites and scales, but
    their skills have never been compared. As part of the activities of the International
    Association of Cryospheric Sciences (IACS) Debris Covered Glacier Working Group,
    we present an intercomparison exercise aimed at advancing our understanding of
    model skills in simulating ice melt under a debris layer. We compare 15 models
    with different complexity at nine sites in the European Alps, Caucasus, Chilean
    Andes, Nepalese Himalaya and the Southern Alps of New Zealand, over one melt season.
    We run the models with measured meteorological data from automatic weather stations
    and estimated or measured debris properties. We consider four main model categories:
    (i) energy balance models that calculate melt by solving the physics of heat transfer
    to the debris layer, but require a high amount of input data; (ii) a simplified
    energy balance model; (iii) enhanced temperature-index models; and (iv) simple
    empirical temperature-index models that have been extensively used given their
    low data requirement but require calibration of their empirical parameters. Model
    performance is evaluated using on-site measurements of sub-debris melt (for all
    models) and surface temperature (for models based on the surface energy balance).
    Our results show that physically-based energy balance models and empirical temperature-index
    models perform in a distinct manner. At one end of the spectrum, simple temperature-index
    models are accurate when recalibrated or when using site-specific literature parameters,
    and show poor results when parameters are uncalibrated. At the other end, energy
    balance models show a range of performance: the most accurate energy balance models
    are those with the highest degree of complexity at the atmosphere-debris interface.
    An important data gap emerged from our experiment: the poor performance of all
    models at three sites was related to the poor knowledge of debris properties,
    and specifically of thermal conductivity. Future work should focus on both: (i) consistent
    data acquisition to evaluate existing models and support new model developments;
    (ii) advancing models by accounting for processes such as debris-snow interactions,
    moisture in the debris and refreezing. We suggest that a systematic effort of
    model development using a common model framework could be carried out in phase
    II of the Working Group.'

  text: We explore the use of a photoacid in a chemical reaction cycle, which allows
    for the controlled sol‐to‐gel transition of a saccharide aldehyde‐based self‐assembling
    system. The modulation of the pH with light enables to generate chemical fuels
    in situ, thus triggering monomer activation and gelation. Our efforts represent
    a promising step toward dissipative self‐assembled systems with a higher degree
    of spatiotemporal control.

  text: "Background & Aims: To develop and validate a CT-based radiomics model to
    assess HVPG and predict a composite endpoint of liver-related events (LRE: decompensation
    and liver-related death) in patients with cirrhosis.\r\n\r\nMethods: This retrospective
    study included 357 cirrhosis patients, who received invasive HVPG measurements,
    120 liver-healthy controls (training cohort) and 85 and 100 cirrhosis patients
    (internal and external validation cohorts, respectively), and contrast-enhanced
    abdominal CTs. After volumetric segmentation of the liver and spleen on CT, Bayesian
    parameter optimization was used for selection of extracted features and hyperparameter
    tuning in random forest or elastic net models. Prediction accuracy was evaluated
    using Pearson correlation coefficients of predicted (’radio-HVPG’) and invasive
    HVPG. Discrimination between relevant HVPG cut-offs was determined by receiver
    operating characteristic (ROC) analysis. The predictive value of radio-HVPG and
    invasive-HVPG for LRE was compared using Cox regression models.\r\n\r\nResults:
    Radio-HVPG, predicted by an optimized random forest model based on 74 selected
    CT features, correlated with invasive-HVPG and detected clinically significant
    portal hypertension (CSPH: HVPG ≥ 10 mmHg) on the internal (Pearson r = 0.63,
    AUC 0.89 [95% CI: 0.81–0.96]) and external (Pearson r = 0.62, AUC 0.80 [95% CI:
    0.64–0.91]) validation cohorts. Radio-HVPG predicted LRE when adjusting for MELD
    and albumin (adjusted HR: 1.14 [95% CI: 1.04–1.25], p = 0.005) and performed similarly
    to invasive-HVPG.\r\n\r\nConclusions: Radiomic features accurately predict HVPG
    in patients with cirrhosis and allow risk stratification for LRE in a radiomics-clinical
    signature."

  text: The transport properties of nanofluidic channels are usually studied under
    constant (DC) voltage or pressure driving. However, the frequency response under
    sinusoidal (AC) drivings offers rich insights into the time-dependent transport
    mechanisms. Inspired by recent electrochemical approaches, we investigate the
    couplings between ionic and electronic transport under AC driving. We show that
    conduction electrons of the channel walls participate in ionic current via capacitive
    electrochemical coupling, defining a critical frequency and length scale where
    electron-dominated conductivity emerges. We further analyze how electron–ion coupling
    modifies electro-osmotic flows and demonstrate that fluctuation-induced momentum
    transfer between the electrolyte and wall electrons produces distinct AC transport
    signatures, depending on the charge carrier polarity. Altogether, we establish
    a frequency-dependent transport matrix that couples ionic, electronic, and hydrodynamic
    flows. These findings establish AC nanofluidic transport as a powerful probe of
    interfacial phenomena under confinement and suggest new directions for engineering
    nanofluidic functionalities through electron–electrolyte coupling.

  text: The long-standing notion that genotypes map to phenotypes through simple one
    gene–one trait relationships continues to shape both research in the life sciences
    and public understanding, with implications for policy and funding priorities.
    Yet this paradigm is increasingly recognized as inadequate for explaining continuous
    phenotypic variation and the complex genetic architectures of the genotype–phenotype
    map. Modern genetics emerged from the early 20th-century synthesis of Mendelian
    and biometric schools of heredity, with R.A. Fisher demonstrating early on how
    multiple discrete loci could collectively produce continuous variation. Despite
    this fundamental insight, Mendelism—with its focus on single genes and standardized
    genetic backgrounds—became the dominant framework, shaping current genetics research
    and molecular biology as well as science education. The advent of large-scale
    genomic data has revealed yet again the limitations of this reductionist approach.
    Evidence from quantitative genetics now shows that most phenotypes arise from
    complex networks of many interdependent genes and their dynamic responses to environmental
    perturbations. Here we trace the historical roots of how Mendelian classical genetics
    departed from the biometric school to create the current predominant paradigm
    in genetics, despite fundamentally unresolved issues. Moving on from this one-sided
    paradigm will require systematic development of integrative, evolutionarily grounded
    experimental approaches that better capture the multigenic and context-dependent
    nature of inheritance. Achieving such an extended perspective will require methodological
    innovation, including advances in large-scale (e.g. automated) phenotyping. Dedicated
    research programs will be necessary to advance a new era of genetic research into
    the complex mechanisms underlying phenotypic variation.
acknowledgement: We thank a variety of further colleagues for the many inspiring discussions
  on the nature of heredity, especially the workshops in Berlin. Special thanks also
  to the Stellenbosch Institute for Advanced Studies (STIAS) to provide DT the leisure
  and freedom to write up the first version of this perspective. Thanks also to three
  reviewers who have helped to improve the manuscript. Two dedicated symposia on the
  topic were funded by the Max-Planck Society.

  text: "AM CVn stars are ultra-compact semi-detached binaries consisting of a white
    dwarf primary and a hydrogen-depleted secondary. In this\r\npaper, we present
    spectroscopic and photometric results of 15 transient sources pre-classified as
    AM CVn candidates. Our analysis confirms\r\n9 systems of the type AM CVn, 3 hydrogen-rich
    cataclysmic variables (accreting white dwarfs with near-main-sequence stars for
    donors),\r\nand 3 systems that could be evolved cataclysmic variables. Eight of
    the AM CVn stars are analysed spectroscopically for the first time,\r\nwhich increases
    the number of spectroscopically confirmed AM CVns by about 10%. TESS data revealed
    the orbital period of the AM CVn\r\nstar ASASSN-20pv to be Porb =27.282 min, which
    helps to constrain the possible values of its mass ratio. TESS also helped to
    determine\r\nthe superhump periods of one AM CVn star (ASASSN-19ct, Psh =30.94
    min) and two cataclysmic variables we classify as WZ Sge stars\r\n(Psh =90.77
    min for ZTF18aaaasnn and Psh =91.6min for ASASSN-15na).We identified very different
    abundances in the spectra of theAM\r\nCVns binaries ASASSN-15kf and ASASSN-20pv
    (both Porb ∼27.5min), suggesting different type of donors. Six of the studied
    AMCVns are\r\nX-ray sources, which helped to determine their mass accretion rates.
    Photometry shows that the duration of all the superoutbursts detected\r\nin the
    AM CVns is consistent with expectations from the disc instability model. Finally,
    we provide refined criteria for the identification of\r\nnew systems using all-sky
    surveys such as LSST."

  Gemini Observatory North and South) The Digitized Sky\r\nSurveys were produced at
  the Space Telescope Science Institute under U.S.\r\nGovernment grant NAG W-2166.
  The images of these surveys are based on\r\nphotographic data obtained using the
  Oschin Schmidt Telescope on Palomar\r\nMountain and the UK Schmidt Telescope. The
  plates were processed into the\r\npresent compressed digital form with the permission
  of these institutions.\r\nThe National Geographic Society – Palomar Observatory
  Sky Atlas (POSS-I)\r\nwas made by the California Institute of Technology with grants
  from the\r\nNational Geographic Society. The Second Palomar Observatory Sky Survey\r\n(POSS-II)
  was made by the California Institute of Technology with funds\r\nfrom the National
  Science Foundation, the National Geographic Society, the\r\nSloan Foundation, the
  Samuel Oschin Foundation, and the Eastman Kodak\r\nCorporation. The Oschin Schmidt
  Telescope is operated by the California\r\nInstitute of Technology and Palomar Observatory.
  The UK Schmidt Telescope\r\nwas operated by the Royal Observatory Edinburgh, with
  funding from the\r\nUK Science and Engineering Research Council (later the UK Particle
  Physics\r\nand Astronomy Research Council), until 1988 June, and thereafter by the\r\nAnglo-Australian
  Observatory. The blue plates of the southern Sky Atlas\r\nand its Equatorial Extension
  (together known as the SERC-J), as well as the\r\nEquatorial Red (ER), and the Second
  Epoch [red] Survey (SES) were all taken\r\nwith the UK Schmidt. Supplemental funding
  for sky-survey work at the ST\r\nScI is provided by the European Southern Observatory.

  text: Little red dots (LRDs) are a newly identified class of broad-line active galactic
    nuclei (AGNs) with a distinctive V-shaped spectrum characterized by red optical
    and blue UV continuum emission. Their high abundance at redshifts of z ∼ 6–8 and
    decline at lower redshifts suggest a transient origin. We propose that the spectral
    shape of LRDs originates from compact binary black hole systems, in which each
    black hole is surrounded by a mini-disk and embedded within a larger circumbinary
    disk. With a binary separation of ≲103 Schwarzschild radii, the Wien tail of a
    T ≃ 5000 K blackbody spectrum at the inner edge of the circumbinary disk produces
    the red optical emission, while the mini-disks power the UV continuum. Binary
    torques carve out a gap between the circumbinary disk and the mini-disks, setting
    the turnover wavelength of the V-shaped spectrum around the Balmer limit. This
    scenario naturally reproduces LRD spectra requiring only modest dust attenuation
    (AV ≲ 1 mag), resolving overestimated luminosities for LRDs in previous studies
    and alleviating a tension with the so-called Sołtan argument. This model predicts
    distinct spectral evolution as the binary orbit decays through binary disk interactions
    and gravitational-wave (GW) emission, linking early-stage “proto-LRD” binaries
    to the broader AGN population and late-stage “LRD descendants” to coalescing binaries
    detectable in GW experiments.

  text: UTe2 exhibits the remarkable phenomenon of re-entrant superconductivity, whereby
    the zero-resistance state reappears above 40 tesla after being suppressed with
    a field of around 10 tesla. One potential pairing mechanism, invoked in the related
    re-entrant superconductors UCoGe and URhGe, involves transverse fluctuations of
    a ferromagnetic order parameter. However, the requisite ferromagnetic order—present
    in both UCoGe and URhGe—is absent in UTe2, and neutron scattering shows instead
    that the magnetic susceptibility is peaked at an antiferromagnetic wavevector.
    Here, we measure the magnetotropic susceptibility of UTe2 across two field-angle
    planes. This quantity is sensitive to the magnetic susceptibility in a direction
    transverse to the applied magnetic field—a quantity that is not accessed in conventional
    magnetization measurements. We observe a very large decrease in the magnetotropic
    susceptibility over a broad range of field orientations, indicating a large increase
    in the transverse magnetic susceptibility. Because our technique probes the magnetic
    susceptibility in the long wavelength (q = 0) limit, this suggests that the strong
    transverse susceptibility arises from ferromagnetic spin fluctuations. These ferromagnetic
    fluctuations are likely important for understanding the pairing mechanism in UTe2,
    as all three superconducting phases of UTe2 surround this region of enhanced susceptibility
    in the field-angle phase diagram.

  text: 'We compile a sample of 83 little red dots (LRDs) with JWST imaging and find
    that a substantial fraction (∼43%, rising to ≳80% for the most luminous LRDs)
    host one or more spatially offset, UV-bright companions at projected separations
    of 0.5 kpc ≲ d ≲ 5 kpc, with median 〈d〉 = 1.0 kpc. This fraction is even higher
    when smaller spatial scales are probed at high signal-to-noise ratio: the two
    most strongly lensed LRDs, A383-LRD1 and the newly discovered A68-LRD1, both have
    UV-bright companions at separations of only d ∼ 0.3 kpc, below the resolution
    limit of most unlensed JWST samples. We explore whether these ubiquitous red/blue
    configurations may be physically linked to the formation of LRDs, in analogy with
    the “synchronized pair” scenario originally proposed for direct-collapse black
    hole formation. In this picture, UV radiation from the companions, with typically
    modest stellar masses (M∗ ∼ 108−109 M⊙), suppresses molecular hydrogen cooling
    in nearby gas, allowing nearly isothermal collapse and the formation of extremely
    compact objects, such as massive black holes, supermassive stars, or quasi-stars.
    Using component-resolved photometry and spectral energy distribution modeling,
    we infer Lyman–Werner radiation fields of J21,LW ∼ 102.5–105 at the locations
    of the red components, comparable to those required in direct-collapse models,
    suggesting that the necessary photodissociation conditions are realized in many
    LRD systems. This framework provides a simple and self-consistent explanation
    for the extreme compactness and distinctive spectral properties of LRDs and links
    long-standing theoretical models for early compact object formation directly to
    a population now observed with JWST in the early Universe.'

  text: Analog quantum simulators provide access to many-body dynamics beyond the
    reach of classical computation. However, extracting physical insights from experimental
    data is often hindered by measurement noise, limited observables, and incomplete
    knowledge of the underlying microscopic model. Here, we develop a machine learning
    approach based on a variational autoencoder (VAE) to analyze interference measurements
    of tunnel-coupled one-dimensional Bose gases, which realize the sine-Gordon quantum
    field theory. Trained in an unsupervised manner, the VAE learns a minimal latent
    representation that strongly correlates with the equilibrium control parameter
    of the system. Applied to nonequilibrium protocols, the latent space uncovers
    signatures of frozen-in solitons following rapid cooling, and reveals anomalous
    postquench dynamics not captured by conventional correlation-based methods. These
    results demonstrate that generative models can extract physically interpretable
    variables directly from noisy and sparse experimental data, providing complementary
    probes of equilibrium and nonequilibrium physics in quantum simulators. More broadly,
    our work highlights how machine learning can supplement established field-theoretical
    techniques, paving the way for scalable, data-driven discovery in quantum many-body
    systems.

  text: 'Despite the success of mRNA therapeutics, challenges remain in optimizing
    immune responses and minimizing side effects. Cell-specific antigen delivery may
    help reduce required doses and improve vaccine efficacy. In this study, we report
    on a targeted delivery system for mRNA to a specific subset of skin-resident antigen-presenting
    cells: Langerhans cells. By functionalizing lipid nanoparticles with a langerin-specific
    glycomimetic ligand, we achieve selective mRNA delivery to both murine and human
    primary Langerhans cells with minimal off-target uptake, at the same time resulting
    in significantly increased mRNA translation. This targeted mRNA delivery not only
    enhances antigen presentation and T-cell responses but also enables dose-sparing
    and superior antitumor immunity compared with conventional immunization in a B16-OVA
    tumor model. Importantly, our platform’s high compatibility with various lipid
    nanoparticle formulations offers a flexible and precise tool for skin-directed
    mRNA delivery.'

  text: The development of complex tissues relies on the precise assignment of cell
    identity. At the molecular scale, this process depends on the deposition of epigenetic
    modifications—such as methylation—that are regulated by complex biochemical networks
    and occur at specific regions on the DNA and chromatin. Here we show that despite
    the complexity of epigenetic regulation, dynamical scaling and self-similarity
    of DNA methylation marks emerge in embryonic development. Drawing on single-cell
    multi-omics experiments, super-resolution microscopy and statistical physics,
    we demonstrate that these phenomena originate in dynamical feedback between DNA
    methylation and the formation of nanoscale dynamic chromatin aggregates. These
    nanoscale processes lead to genome-wide increase in DNA methylation marks following
    a power law and self-similar correlation functions. Using this framework, we identify
    methylation patterns that precede gene expression changes in embryonic symmetry
    breaking. Our work identifies linear sequencing measurements as a laboratory to
    study mesoscopic biophysical processes in vivo.

  text: "As neural-network-based models grow both in size and popularity, interest
    has grown in making the models smaller and more efficient to train. To that end,
    many methods have been proposed to prune models by reducing their number of nonzero
    parameters. Additionally, parameter-efficient fine-tuning, in which a much smaller
    number of parameters than the total contained in the model is updated during training,
    has become very popular, especially in the space of Large Language Models. At
    the same time, the increasingly routine deployment of machine learning in real-world
    applications has spurred a drive to make them more trustworthy - in the sense
    of, among other things, being unbiased, interpretable, and editable. In this thesis,
    we examine the interplay between efficiency and trustworthiness.\r\n\r\nFirst,
    we analyze the effects of model pruning on bias in computer vision models, demonstrating
    that increased sparsity leads to greater bias, largely as a function of increased
    model uncertainty in marginal cases. Based on this observation, we propose several
    bias mitigation techniques. Then, we demonstrate that example-specific model pruning
    can improve model interpretation methods while improving pruning efficiency to
    make example-specific model pruning feasible in real time. Then, we investigate
    the effectiveness of parameter-efficient and data-efficient model personalization
    via fine-tuning, demonstrating that it is highly feasible with very small computational
    and data resources. Finally, we consider efficiency in editing model knowledge
    using a custom synthetic data framework, demonstrating that parameter-efficient,
    low-rank fine-tuning frequently outperforms full-rank fine-tuning, and, additionally,
    that restricting which model blocks are fine-tuned frequently improves results.
    Together, the results in this thesis provide new insights and techniques for combining
    trustworthiness and efficiency during neural network inference and training.\r\n\r\n-----------------“In

  text: "The availability of powerful open-source large language models (LLMs) opens
    exciting use cases, such as using personal data to fine-tune these models to imitate
    a user’s unique writing style. Two key requirements for this functionality are
    personalization–in the sense that the output should recognizably reflect the user’s
    own writing style—and privacy–users may justifiably be wary of uploading extremely
    personal data, such as their email archive, to a third-party service. In this
    paper, we demonstrate the feasibility of training and running such an assistant,
    which we call Panza, on commodity hardware, for the specific use case of email
    generation. Panza’s personalization features are based on a combination of parameter-efficient
    fine-tuning using a variant of the Reverse Instructions technique [1] and Retrieval-Augmented
    Generation (RAG) [2]. We demonstrate that this combination allows us to fine-tune
    an LLM to reflect a user’s writing style using limited data, while executing on
    extremely limited resources, e.g. on a free Google Colab instance. Our key methodological
    contribution is the first detailed study of evaluation metrics for this task,
    and\r\nof how different choices of system components–the use of RAG and of different
    fine-tuning approaches–impact the system’s performance. Additionally, we demonstrate
    that very little data - under 100 email samples - are sufficient to create models
    that convincingly imitate humans, showcasing a previously unknown attack vector
    in language models. We are releasing the full Panza code as well as three new
    email datasets licensed for research use."

  text: As artificial neural networks, and specifically large language models, have
    improved rapidly in capabilities and quality, they have increasingly been deployed
    in real-world applications, from customer service to Google search, despite the
    fact that they frequently make factually incorrect or undesirable statements.
    This trend has inspired practical and academic interest in model editing, that
    is, in adjusting the weights of the model to modify its likely outputs for queries
    relating to a specific fact or set of facts. This may be done either to amend
    a fact or set of facts, for instance, to fix a frequent error in the training
    data, or to suppress a fact or set of facts entirely, for instance, in case of
    dangerous knowledge. Multiple methods have been proposed to do such edits. However,
    at the same time, it has been shown that such model editing can be brittle and
    incomplete. Moreover the effectiveness of any model editing method necessarily
    depends on the data on which the model is trained, and, therefore, a good understanding
    of the interaction of the training data distribution and the way it is stored
    in the network is necessary and helpful to reliably perform model editing. However,
    working with large language models trained on real-world data does not allow us
    to understand this relationship or fully measure the effects of model editing.
    We therefore propose Behemoth, a fully synthetic data generation framework. To
    demonstrate the practical insights from the framework, we explore model editing
    in the context of simple tabular data, demonstrating surprising findings that,
    in some cases, echo real-world results, for instance, that in some cases restricting
    the update rank results in a more effective update.

  text: Glutamate excitotoxicity is a cell death mechanism triggered by accumulation
    of glutamate in the extracellular space. The α-ketoglutarate dehydrogenase complex
    (αKGDHC), an enzyme of the tricarboxylic acid cycle, represents a branching point
    controlling glutamate formation and its consumption as a fuel. Hence, modulation
    of the activity of αKGDHC might alter the amount of glutamate available for excitotoxic
    effects. To address this hypothesis, hippocampal neurons in primary co-culture
    with glial cells were exposed to zero-Mg2 buffer to elicit excitotoxicity through
    N-methyl-D-aspartic acid (NMDA) receptor disinhibition. Pretreatment of the cultures
    with succinyl phosphonate, to inhibit αKGDHC, enhanced excitotoxity, whereas promotion
    of αKGDHC activity by pretreatment with thiamine caused an opposite action. Moreover,
    NMDA receptor currents – but not those mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic
    acid (AMPA) receptors – were potentiated in neurons with impaired αKGDHC activity
    and diminished in neurons with boosted αKGDHC activity. The sensitization of NMDA
    receptors involved mGluR1 activation and was accompanied by enhanced neuronal
    discharge activity, elevated basal cytosolic Ca2+ levels, and augmented Ca2+ responses
    evoked by glutamate application. These results suggest that mGluR1-mediated potentiation
    of NMDA receptors contributes to a mechanism by which inhibition of αKGDHC might
    exacerbate glutamate excitotoxicity.
