The plasmid-encoded ParMRC system forms actin-like filaments that segregate low–copy number plasmids. In multicellular cyanobacteria such as Anabaena sp., we found that a chromosomally encoded ParMR system has evolved into a cytoskeletal system named CorMR with a function in cell shape control rather than DNA segregation. Live-cell imaging, in vitro reconstitution, and cryo–electron microscopy revealed that CorM formed dynamically unstable, antiparallel double-stranded filaments that were recruited to the membrane by CorR through an amphipathic helix conserved in multicellular cyanobacteria. CorMR filaments were regulated by MinC, which excluded them from the poles and division plane. Comparative genomics indicated that the repurposing of ParMR and Min systems coevolved with cyanobacterial multicellularity, highlighting the evolutionary plasticity of cytoskeletal systems in bacteria."}],"ec_funded":1,"intvolume":" 392","publication":"Science","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2026-04-26T22:01:46Z","year":"2026","date_published":"2026-04-16T00:00:00Z","project":[{"name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020"},{"name":"A molecular atlas of Actin filament IDentities in the cell motility machinery","grant_number":"101076260","_id":"bd980d18-d553-11ed-ba76-ceaa645c97eb"}],"date_updated":"2026-04-28T13:29:05Z","volume":392,"acknowledged_ssus":[{"_id":"Bio"},{"_id":"ScienComp"},{"_id":"EM-Fac"},{"_id":"LifeSc"}],"title":"Repurposing of a DNA segregation machinery into a cytoskeletal system controlling cell shape","OA_type":"closed access","scopus_import":"1","oa_version":"None","acknowledgement":"We thank all members of the Loose lab at ISTA for helpful discussions; M.

In this study, we developed a method of live imaging of apoplastic ROS at the root surface. Distinct signals, including auxin, extracellular adenosine triphosphate, and rapid alkalinization factor 1 peptide, induce cytosolic calcium transients and apoplastic ROS bursts. Genetic and optogenetic manipulations of Arabidopsis identified calcium transients as necessary and sufficient for ROS bursts through activation of reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidases RBOHC and RBOHF. Apoplastic ROS bursts are not required, but they do limit gravity-induced root bending. Root bending is sensed by the stretch-activated calcium channel MCA1, leading to NADPH oxidase activation. The resulting ROS production stiffens cell walls to facilitate soil penetration. Apoplastic ROS thus provides a means to balance tissue flexibility and stiffness to navigate soil."}],"doi":"10.1126/science.adu8197","publication_status":"published","department":[{"_id":"JiFr"},{"_id":"GradSch"}],"external_id":{"pmid":["41990180"]},"date_updated":"2026-05-07T06:20:07Z","volume":392,"date_published":"2026-04-16T00:00:00Z","project":[{"grant_number":"101142681","_id":"8f347782-16d5-11f0-9cad-8c19706ee739","name":"Cyclic nucleotides as second messengers in plants"},{"name":"Guanylate cyclase activity of TIR1/AFBs auxin receptors","_id":"7bcece63-9f16-11ee-852c-ae94e099eeb6","grant_number":"P37051"}],"ddc":["580"],"year":"2026","date_created":"2026-04-26T22:01:47Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Kulich, Ivan, Dmitrii Vladimirtsev, Marek Randuch, Shiqiang Gao, Matteo Citterico, Kai R.

The sign of ω(k) determines whether density modes with wave number k grow or decay over time. We demonstrate the predictive power by investigating the complex phase behavior of particles interacting via core-shoulder pair potentials. With complementary Monte Carlo simulations, we show that regions of the phase diagram where ωðkÞ has one or several unstable (growing) wave numbers are also where crystalline phases occur. Going further, by tuning these\r\nunstable wave numbers via the interaction-potential and state-point parameters, we design systems with quasicrystals in the phase diagram.

The fact that particles can become highly charged as a result of this effect has significant consequences for many settings, both in nature and industry, such as thunderstorms, volcanic eruptions, particle aggregation during meteorite and planet formation, and the clogging of industrial granular systems. Toward understanding these systems, great efforts have been made to develop precise in situ measurements for particle charge, e.g., to determine ensemble charge distributions or measure exchange during individual contacts. Here, we present experimental results concerning the particle size scaling of the stationary-state charge distributions of oxide particles in the sub-millimeter range. We measure the charge distributions for large ensembles of monodisperse ZrO2:SiO2 composite spheres, ranging from 172 to 545µm in diameter. These distributions are non-Gaussian and collapse to a single master curve when plotted as functions of the surface charge density Σ=𝑞/4𝜋𝑅2. X-ray fluorescence and atomic force microscopy measurements show that the differences in the measured charge distributions are not due to variations in chemical composition or surface roughness, but rather to size alone. Our findings provide constraints on microscopic models for charge exchange, namely that they should lead to steady-state distributions that are non-Gaussian and scale in a specific way with particle size.","lang":"eng"}]},{"page":"237-260","status":"public","OA_place":"publisher","type":"journal_article","day":"17","publication_identifier":{"eissn":["2737-114X"],"issn":["2737-0690"]},"publisher":"Finnish Mathematical Society","month":"04","quality_controlled":"1","_id":"21766","corr_author":"1","issue":"1","keyword":["Lipschitz","bilipschitz","extension","separated net."],"article_type":"original","article_processing_charge":"Yes (in subscription journal)","author":[{"last_name":"Dymond","full_name":"Dymond, Michael","first_name":"Michael"},{"orcid":"0000-0002-2512-8698","full_name":"Kaluza, Vojtech","last_name":"Kaluza","id":"21AE5134-9EAC-11EA-BEA2-D7BD3DDC885E","first_name":"Vojtech"}],"license":"https://creativecommons.org/licenses/by-nc/4.0/","oa":1,"language":[{"iso":"eng"}],"title":"Extending bilipschitz mappings between separated nets","OA_type":"hybrid","acknowledgement":"The present work developed from a research visit of M.D. to V.K. at IST Austria, funded by\r\na London Mathematical Society Research in Pairs grant.

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."}],"department":[{"_id":"MassSpec"}],"external_id":{"pmid":["42036976"]},"publication_status":"published"},{"oa":1,"language":[{"iso":"eng"}],"author":[{"first_name":"S.

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.","lang":"eng"}],"doi":"10.1093/mnras/stag521","publication_status":"published","external_id":{"arxiv":["2603.12888"]},"department":[{"_id":"IlCa"}]},{"quality_controlled":"1","month":"04","publisher":"Mathematical Sciences Publishers","publication_identifier":{"issn":["2996-2196"],"eissn":["2996-220X"]},"day":"17","type":"journal_article","OA_place":"repository","status":"public","page":"73-82","oa":1,"language":[{"iso":"eng"}],"author":[{"full_name":"Dumitrescu, Adrian","last_name":"Dumitrescu","first_name":"Adrian"},{"first_name":"János","last_name":"Pach","full_name":"Pach, János"},{"first_name":"Morteza","full_name":"Saghafian, Morteza","last_name":"Saghafian","id":"f86f7148-b140-11ec-9577-95435b8df824"},{"full_name":"Scott, Alex","last_name":"Scott","first_name":"Alex"}],"article_type":"original","article_processing_charge":"No","_id":"21781","issue":"1","acknowledgement":"Research partially supported by ERC Advanced Grant \"GeoScape\", no. 882971 and\r\nHungarian NKFIH grant no.

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"}],"department":[{"_id":"FrPe"}],"publication_status":"published","file":[{"creator":"dernst","access_level":"open_access","date_updated":"2026-05-18T06:07:53Z","file_name":"2026_Cryosphere_Pellicciotti.pdf","file_size":3168394,"checksum":"f15abad4ee360d41a3e8794f068711fc","file_id":"21886","relation":"main_file","date_created":"2026-05-18T06:07:53Z","content_type":"application/pdf","success":1}],"intvolume":" 20","publication":"The Cryosphere","file_date_updated":"2026-05-18T06:07:53Z"},{"acknowledgement":"J.S.V. and T.M.H. acknowledge funding from ERC-2017-STG “Life-Cycle” (757910) and ERC-2022-CoG “Suprabot” (101087514).

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.

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."}],"doi":"10.1063/5.0313352","article_type":"original","article_processing_charge":"Yes (in subscription journal)","issue":"13","_id":"21840","PlanS_conform":"1","oa":1,"language":[{"iso":"eng"}],"author":[{"first_name":"Baptiste","full_name":"Coquinot, Baptiste","orcid":"0000-0001-5524-596X","last_name":"Coquinot","id":"f8417bd4-f599-11ee-a482-b927e3ed1e8e"},{"first_name":"Mathieu","full_name":"Lizée, Mathieu","last_name":"Lizée"},{"first_name":"Lydéric","last_name":"Bocquet","full_name":"Bocquet, Lydéric"},{"full_name":"Kavokine, Nikita","last_name":"Kavokine","first_name":"Nikita"}],"type":"journal_article","day":"07","status":"public","OA_place":"publisher","month":"04","quality_controlled":"1","article_number":"134704","publication_identifier":{"issn":["0021-9606"],"eissn":["1089-7690"]},"publisher":"AIP Publishing","citation":{"short":"B.

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."}],"department":[{"_id":"NiBa"}],"external_id":{"pmid":["41701356"]},"publication_status":"published","date_updated":"2026-05-18T07:51:26Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":232,"date_published":"2026-04-01T00:00:00Z","ddc":["570"],"date_created":"2026-05-07T08:53:40Z","year":"2026","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"date_published":"2026-03-27T00:00:00Z","ddc":["520"],"date_updated":"2026-05-12T06:57:40Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":43,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2026","date_created":"2026-05-07T08:55:00Z","file_date_updated":"2026-05-12T06:54:10Z","intvolume":" 43","publication":"Publications of the Astronomical Society of Australia","file":[{"content_type":"application/pdf","success":1,"date_created":"2026-05-12T06:54:10Z","relation":"main_file","checksum":"f8f3cd3765948e8b276176c71c9d4e02","file_id":"21862","file_size":3681016,"file_name":"2026_PublAstronomicalSocAustralia_Kara.pdf","date_updated":"2026-05-12T06:54:10Z","access_level":"open_access","creator":"dernst"}],"publication_status":"published","department":[{"_id":"IlCa"}],"abstract":[{"text":"AM CVn stars are ultra-compact semi-detached binaries consisting of a white dwarf primary and a hydrogen-depleted secondary.

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"}],"DOAJ_listed":"1","_id":"21844","issue":"1","PlanS_conform":"1","article_processing_charge":"Yes","article_type":"original","author":[{"first_name":"Kohei","last_name":"Inayoshi","full_name":"Inayoshi, Kohei"},{"first_name":"Jinyi","full_name":"Shangguan, Jinyi","last_name":"Shangguan"},{"first_name":"Xian","full_name":"Chen, Xian","last_name":"Chen"},{"full_name":"Ho, Luis C.","last_name":"Ho","first_name":"Luis C."},{"last_name":"Haiman","orcid":"0000-0003-3633-5403","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán"}],"language":[{"iso":"eng"}],"oa":1,"status":"public","OA_place":"publisher","type":"journal_article","day":"01","publisher":"IOP Publishing","article_number":"25","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"month":"05","quality_controlled":"1","has_accepted_license":"1","citation":{"chicago":"Inayoshi, Kohei, Jinyi Shangguan, Xian Chen, Luis C.
