In this study, we developed a survey to collect the self-perception of animal care staff (ACS) and laboratory technicians about their involvement in scientific planning and conduct. Participants were contacted to complete an anonymous online questionnaire. We obtained 850 responses, mainly from Europe: 564 from ACS and 286 from laboratory technicians. Job satisfaction was assessed as positive by ACS and laboratory technicians despite the low frequency of culture of care activities and mental health meetings. Both groups expressed their desire to be trained in research planning and conduct; however, regular training was not reported. In addition, the inability to act on animal welfare concerns owing to experimental reasons was reported by both groups. Over half of the participants felt valued and appreciated by the lead scientists or animal facility manager; however, it is not clear how they are acknowledged, as their names on the authors list or in the manuscript acknowledgments are barely included. Our results indicated that involvement of ACS and laboratory technicians in planning and conducting studies would improve their understanding of how experiments are done, and therefore communication processes, work satisfaction, animal welfare, and scientific quality. Finally, we provided recommendations to improve the engagement of ACS and laboratory technicians in discussions about animal research planning and conduct.","lang":"eng"},{"text":"La participation de personnel non-scientifique aux discussions sur le bien-être animal et la qualité scientifique est essentielle aux progrès la recherche biomédicale.

De plus, l'incapacité d'agir sur les préoccupations relatives au bien-être animal pour des raisons expérimentales a été signalée par les deux groupes.

Die Teilnehmer wurden gebeten, einen anonymen Online-Fragebogen auszufüllen. Wir erhielten 850 Rückmeldungen, hauptsächlich aus Europa: 564 von ACS und 286 von LT. Die Arbeitszufriedenheit wurde von ACS und LT trotz der geringen Häufigkeit von Pflegeaktivitäten und Treffen zum Thema psychische Gesundheit als positiv bewertet. Beide Gruppen äußerten den Wunsch, in der Forschungsplanung und -durchführung geschult zu werden, doch regelmäßig stattfindende Schulungen wurden nicht berichtet. Außerdem wurde von beiden Gruppen vermeldet, dass sie aus versuchstechnischen Gründen nicht in der Lage waren, auf Tierschutzbedenken zu reagieren. Über die Hälfte der Teilnehmer fühlte sich von den leitenden Wissenschaftlern oder dem Leiter der Tierhaltungseinrichtung geschätzt und anerkannt; es ist jedoch unklar, inwiefern sie wirklich gewürdigt werden, da ihre Namen kaum in der Autorenliste oder in den Danksagungen des Manuskripts aufgeführt sind. Unsere Ergebnisse deuteten darauf hin, dass die Einbeziehung von ACS und LT in die Planung und Durchführung von Studien ihr Verständnis für die Durchführung von Experimenten verbessern würde – und damit auch Kommunikationsprozesse, Arbeitszufriedenheit, Tierwohl und wissenschaftliche Qualität. Abschließend gaben wir Empfehlungen zur Verbesserung der Einbeziehung von ACS und LT in Diskussionen über die Planung und Durchführung von Tierversuchen."},{"text":"La participación del personal no científico en los debates sobre el bienestar animal y la calidad científica es fundamental para el avance de la investigación biomédica.

Aside from solution NMR, an increasing number of studies have been conducted applying solid-state magic-angle spinning (MAS) NMR to fluorine-labelled samples. Here, the high chemical shift anisotropy and strong dipolar couplings can be utilised to get structural insights into proteins and measure long distances. Despite increasing popularity and promising benefits, the sensitivity of biomolecular 19F MAS NMR often suffers from slow longitudinal T1 relaxation and therefore long recycle delays. In this work, we expand paramagnetic doping, an approach commonly used to reduce proton T1 relaxation times, to 19F-labelled biological samples. We study the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F T1 and T2, and 13C T1 and T2 relaxation in a [5-19F13C]-tryptophan-labelled protein via 19F-detected MAS NMR experiments. The observed paramagnetic relaxation enhancement substantially reduces measurement times of 19F MAS NMR experiments without compromising resolution.

Despite being highly active against mycobacteria in vitro, its development as an anti-tubercular agent has been hindered due to suboptimal pharmacokinetics. Engineering of the acidomycin biosynthesis may yield new analogues with improved pharmacological properties. Here, we describe the identification of the acidomycin biosynthetic gene cluster (BGC) in a Streptomyces bacterium isolated from the rhizosphere of Edelweiss. Notably, the acidomycin BGC is located in proximity to the genes for the biosynthesis of stravidins, secondary metabolites targeting a different enzyme in the biotin biosynthesis pathway, and two genes for streptavidins, proteins that strongly bind and sequester biotin. The identity of the acidomycin BGC was confirmed via both gene knock-out and heterologous expression, which suggested that the fatty acid required for the formation of acidomycin's acyl chain is most likely scavenged from the biotin biosynthesis pathway. CRISPR/Cas9-assisted knock-out of the cytochrome P450-encoding gene in the acidomycin BGC resulted in a significant decrease in its yield but did not abrogate the biosynthesis completely."}],"article_processing_charge":"Yes","doi":"10.1111/1751-7915.70357","article_type":"original","oa":1,"file_date_updated":"2026-05-07T08:21:06Z","oa_version":"Published Version","date_updated":"2026-05-07T08:22:41Z","has_accepted_license":"1","month":"04","OA_type":"gold","acknowledgement":"This work was supported by the University of Vienna.

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."}],"doi":"10.1093/mnras/stag521","ddc":["520"]},{"arxiv":1,"page":"73-82","date_published":"2026-04-17T00:00:00Z","intvolume":" 15","OA_place":"repository","department":[{"_id":"HeEd"}],"publication_identifier":{"issn":["2996-2196"],"eissn":["2996-220X"]},"citation":{"short":"A.

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.","lang":"eng"}],"doi":"10.5194/tc-20-1895-2026","author":[{"last_name":"Pellicciotti","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","orcid":"0000-0002-5554-8087","full_name":"Pellicciotti, Francesca","first_name":"Francesca"},{"id":"f06891fd-9f42-11ee-8632-a20971c43046","last_name":"Fontrodona-Bach","full_name":"Fontrodona-Bach, Adrià","first_name":"Adrià"},{"full_name":"Rounce, David R.","first_name":"David R.","last_name":"Rounce"},{"full_name":"Fyffe, Catriona Louise","first_name":"Catriona Louise","id":"001b0422-8d15-11ed-bc51-cab6c037a228","last_name":"Fyffe"},{"last_name":"Anderson","full_name":"Anderson, Leif S.","first_name":"Leif S."},{"last_name":"Ayala","full_name":"Ayala, Álvaro","first_name":"Álvaro"},{"last_name":"Brock","full_name":"Brock, Ben W.","first_name":"Ben W."},{"first_name":"Pascal","full_name":"Buri, Pascal","last_name":"Buri"},{"first_name":"Stefan","full_name":"Fugger, Stefan","last_name":"Fugger"},{"last_name":"Fujita","first_name":"Koji","full_name":"Fujita, Koji"},{"last_name":"GANTAYAT","id":"02734268-3e8d-11ef-80a1-cec4a088d004","first_name":"PRATEEK","full_name":"GANTAYAT, PRATEEK"},{"last_name":"Groos","first_name":"Alexander R.","full_name":"Groos, Alexander R."},{"last_name":"Immerzeel","full_name":"Immerzeel, Walter","first_name":"Walter"},{"full_name":"Kneib, Marin","first_name":"Marin","last_name":"Kneib"},{"last_name":"Mayer","first_name":"Christoph","full_name":"Mayer, Christoph"},{"last_name":"MacDonell","full_name":"MacDonell, Shelley","first_name":"Shelley"},{"first_name":"Michael","full_name":"McCarthy, Michael","last_name":"McCarthy","id":"22a2674a-61ce-11ee-94b5-d18813baf16f"},{"first_name":"James","full_name":"McPhee, James","last_name":"McPhee"},{"full_name":"Miles, Evan","first_name":"Evan","last_name":"Miles"},{"full_name":"Purdie, Heather","first_name":"Heather","last_name":"Purdie"},{"first_name":"Ekaterina","full_name":"Rets, Ekaterina","last_name":"Rets"},{"last_name":"Sakai","first_name":"Akiko","full_name":"Sakai, Akiko"},{"orcid":"0000-0001-7640-6152","full_name":"Shaw, Thomas","first_name":"Thomas","last_name":"Shaw","id":"3caa3f91-1f03-11ee-96ce-e0e553054d6e"},{"last_name":"Steiner","first_name":"Jakob","full_name":"Steiner, Jakob"},{"last_name":"Wagnon","first_name":"Patrick","full_name":"Wagnon, Patrick"},{"last_name":"Winter-Billington","first_name":"Alex","full_name":"Winter-Billington, Alex"}],"_id":"21837","publisher":"Copernicus Publications","publication_status":"published","day":"02","oa_version":"Published Version","file_date_updated":"2026-05-18T06:07:53Z","oa":1,"article_type":"original","OA_type":"gold","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme grant agreement No\r\n772751, RAVEN, “Rapid mass losses of debris covered glaciers in\r\nHigh Mountain Asia”.

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.","lang":"eng"}],"article_processing_charge":"Yes (via OA deal)","_id":"21839","external_id":{"pmid":["41943460"]},"author":[{"last_name":"Sin","first_name":"Celine","full_name":"Sin, Celine"},{"first_name":"Martin Luther","full_name":"Watzenboeck, Martin Luther","last_name":"Watzenboeck"},{"last_name":"Iofinova","id":"f9a17499-f6e0-11ea-865d-fdf9a3f77117","orcid":"0000-0002-7778-3221","full_name":"Iofinova, Eugenia B","first_name":"Eugenia B"},{"first_name":"Lorenz","full_name":"Balcar, Lorenz","last_name":"Balcar"},{"last_name":"Semmler","first_name":"Georg","full_name":"Semmler, Georg"},{"first_name":"Bernhard","full_name":"Scheiner, Bernhard","last_name":"Scheiner"},{"last_name":"Lampichler","full_name":"Lampichler, Katharina","first_name":"Katharina"},{"first_name":"Mattias","full_name":"Mandorfer, Mattias","last_name":"Mandorfer"},{"last_name":"Moga","first_name":"Lucile","full_name":"Moga, Lucile"},{"first_name":"Pierre‐Emmanuel","full_name":"Rautou, Pierre‐Emmanuel","last_name":"Rautou"},{"full_name":"Ronot, Maxime","first_name":"Maxime","last_name":"Ronot"},{"first_name":"Jörg","full_name":"Menche, Jörg","last_name":"Menche"},{"last_name":"Reiberger","full_name":"Reiberger, Thomas","first_name":"Thomas"},{"last_name":"Scharitzer","first_name":"Martina","full_name":"Scharitzer, Martina"}],"publication_status":"published","publisher":"Wiley","day":"01","ddc":["570"],"article_number":"e70633","date_published":"2026-05-01T00:00:00Z","intvolume":" 46","OA_place":"publisher","publication_identifier":{"issn":["1478-3223"],"eissn":["1478-3231"]},"citation":{"ista":"Sin C, Watzenboeck ML, Iofinova EB, Balcar L, Semmler G, Scheiner B, Lampichler K, Mandorfer M, Moga L, Rautou P, Ronot M, Menche J, Reiberger T, Scharitzer M. 2026.

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.","lang":"eng"}],"doi":"10.1063/5.0313352","publisher":"AIP Publishing","_id":"21840","publication_status":"published","external_id":{"arxiv":["2505.02478"]},"author":[{"last_name":"Coquinot","id":"f8417bd4-f599-11ee-a482-b927e3ed1e8e","orcid":"0000-0001-5524-596X","full_name":"Coquinot, Baptiste","first_name":"Baptiste"},{"last_name":"Lizée","full_name":"Lizée, Mathieu","first_name":"Mathieu"},{"last_name":"Bocquet","full_name":"Bocquet, Lydéric","first_name":"Lydéric"},{"full_name":"Kavokine, Nikita","first_name":"Nikita","last_name":"Kavokine"}],"day":"07","ddc":["530"],"OA_type":"hybrid","acknowledgement":"The authors thank Nicolas Chapuis for fruitful discussions.

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."}],"article_processing_charge":"Yes (in subscription journal)","ddc":["570"],"has_accepted_license":"1","date_updated":"2026-05-18T07:51:26Z","month":"04","OA_type":"hybrid","acknowledgement":"We thank a variety of further colleagues for the many inspiring discussions on the nature of heredity, especially the workshops in Berlin.

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.","lang":"eng"}],"article_processing_charge":"Yes (in subscription journal)","doi":"10.1017/pasa.2026.10184","_id":"21842","publication_status":"published","author":[{"full_name":"Kára, Jan","first_name":"Jan","last_name":"Kára"},{"last_name":"Rivera Sandoval","full_name":"Rivera Sandoval, Liliana","first_name":"Liliana"},{"last_name":"Mendoza","first_name":"Wendy","full_name":"Mendoza, Wendy"},{"full_name":"Maccarone, Thomas","first_name":"Thomas","last_name":"Maccarone"},{"last_name":"Pichardo Marcano","full_name":"Pichardo Marcano, Manuel","first_name":"Manuel"},{"full_name":"Salazar Manzano, Luis E.","first_name":"Luis E.","last_name":"Salazar Manzano"},{"full_name":"Oelkers, Ryan J.","first_name":"Ryan J.","last_name":"Oelkers"},{"full_name":"van Roestel, Joannes C","first_name":"Joannes C","id":"4d122fc8-6083-11f0-87a5-97d68b860333","last_name":"van Roestel"}],"publisher":"Cambridge University Press","day":"27"},{"volume":1002,"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"K.

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.","lang":"eng"}],"doi":"10.3847/1538-4357/ae548d","day":"01","publication_status":"published","_id":"21844","publisher":"IOP Publishing","external_id":{"arxiv":["2505.05322"]},"author":[{"full_name":"Inayoshi, Kohei","first_name":"Kohei","last_name":"Inayoshi"},{"last_name":"Shangguan","first_name":"Jinyi","full_name":"Shangguan, Jinyi"},{"full_name":"Chen, Xian","first_name":"Xian","last_name":"Chen"},{"last_name":"Ho","full_name":"Ho, Luis C.","first_name":"Luis C."},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","first_name":"Zoltán","full_name":"Haiman, Zoltán","orcid":"0000-0003-3633-5403"}],"ddc":["520"],"acknowledgement":"We greatly thank Kenta Hotokezaka and Hanpu Liu for constructive discussions.

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.","lang":"eng"}],"doi":"10.1038/s41467-026-71899-7","day":"29","project":[{"grant_number":"101078696","_id":"bd968c70-d553-11ed-ba76-cde40b0aba64","name":"Gaining leverage with spin liquids and superconductors"}],"external_id":{"arxiv":["2506.08984"]},"_id":"21845","publication_status":"published","author":[{"id":"467ed36b-dc96-11ea-b7c8-b043a380b282","last_name":"Zambra","first_name":"Valeska","full_name":"Zambra, Valeska","orcid":"0000-0002-8806-5719"},{"full_name":"Nathwani, Amit","first_name":"Amit","id":"1a362536-4d02-11f1-8543-8351136efc50","last_name":"Nathwani"},{"id":"32c21954-2022-11eb-9d5f-af9f93c24e71","last_name":"Nauman","full_name":"Nauman, Muhammad","orcid":"0000-0002-2111-4846","first_name":"Muhammad"},{"first_name":"Sylvia K.","full_name":"Lewin, Sylvia K.","last_name":"Lewin"},{"last_name":"Frank","full_name":"Frank, Corey E.","first_name":"Corey E."},{"last_name":"Butch","full_name":"Butch, Nicholas P.","first_name":"Nicholas P."},{"full_name":"Shekhter, Arkady","first_name":"Arkady","last_name":"Shekhter"},{"full_name":"Ramshaw, B.

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.","lang":"eng"}],"publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"department":[{"_id":"ZoHa"},{"_id":"JoMa"}],"OA_place":"publisher","intvolume":" 1002","DOAJ_listed":"1","PlanS_conform":"1","date_published":"2026-04-10T00:00:00Z","article_number":"L4","arxiv":1,"issue":"1","type":"journal_article","year":"2026","publication":"The Astrophysical Journal Letters","title":"Connecting the dots: UV-bright companions of Little Red Dots as Lyman–Werner sources enabling direct-collapse Black Hole formation","file":[{"success":1,"access_level":"open_access","file_id":"21851","creator":"dernst","file_name":"2026_AstrophysicalJourLetters_Baggen.pdf","checksum":"8c31d8603cd6ad39c772a72d136dc3f8","relation":"main_file","file_size":13359642,"content_type":"application/pdf","date_created":"2026-05-11T06:44:37Z","date_updated":"2026-05-11T06:44:37Z"}],"language":[{"iso":"eng"}],"quality_controlled":"1","scopus_import":"1","date_created":"2026-05-10T22:02:15Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","volume":1002,"citation":{"chicago":"Baggen, Josephine F.W., Matthew T.

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."}],"day":"29","publisher":"American Physical Society","_id":"21847","external_id":{"arxiv":["2509.13821"]},"publication_status":"published","author":[{"first_name":"Frederik Skovbo","full_name":"Moller, Frederik Skovbo","id":"43cbcc83-0564-11f0-a935-e37325525859","last_name":"Moller"},{"last_name":"Fernández-Fernández","full_name":"Fernández-Fernández, Gabriel","first_name":"Gabriel"},{"last_name":"Schweigler","first_name":"Thomas","full_name":"Schweigler, Thomas"},{"last_name":"De Schoulepnikoff","first_name":"Paulin","full_name":"De Schoulepnikoff, Paulin"},{"first_name":"Jörg","full_name":"Schmiedmayer, Jörg","last_name":"Schmiedmayer"},{"full_name":"Muñoz-Gil, Gorka","first_name":"Gorka","last_name":"Muñoz-Gil"}]},{"day":"07","publication_status":"inpress","author":[{"last_name":"Klein","first_name":"Klara","full_name":"Klein, Klara"},{"full_name":"Johnson, Litty","first_name":"Litty","last_name":"Johnson"},{"last_name":"Rîca","full_name":"Rîca, Ramona","first_name":"Ramona"},{"full_name":"Sarcevic, Mirza","first_name":"Mirza","last_name":"Sarcevic"},{"first_name":"Gabriele","full_name":"Carta, Gabriele","last_name":"Carta"},{"last_name":"Seiser","first_name":"Saskia","full_name":"Seiser, Saskia"},{"last_name":"Elbe-Bürger","full_name":"Elbe-Bürger, Adelheid","first_name":"Adelheid"},{"full_name":"Langer, Freyja","first_name":"Freyja","id":"3C1BE782-F248-11E8-B48F-1D18A9856A87","last_name":"Langer"},{"last_name":"Rahhal","full_name":"Rahhal, Nowras","first_name":"Nowras"},{"last_name":"Rademacher","first_name":"Christoph","full_name":"Rademacher, Christoph"},{"first_name":"Robert","full_name":"Wawrzinek, Robert","last_name":"Wawrzinek"},{"first_name":"Federica","full_name":"Quattrone, Federica","last_name":"Quattrone"},{"last_name":"Sparber","full_name":"Sparber, Florian","first_name":"Florian"}],"publisher":"Elsevier","_id":"21848","doi":"10.1016/j.jid.2026.03.026","article_processing_charge":"No","abstract":[{"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.","lang":"eng"}],"month":"04","date_updated":"2026-05-11T06:07:32Z","acknowledgement":"We thank Mareike Rentzsch for her intellectual contributions during the course of our discussions.
