The cytokine IL-23 plays important roles in intestinal barrier protection and integrity, but is also linked to chronic inflammation. In this issue of JEM, Ohara et al. (https://doi.org/10.1084/jem.20230923) provide clarity on the much-debated question of which cells produce IL-23.

The catalytic oxidation of HCl by molecular oxygen (Deacon process) over ceria allows the recovery of molecular chlorine from the omnipresent HCl waste produced in various industrial processes. In previous density functional theory (DFT) model-calculations by Amrute et al. [ J. Catal. 2012, 286, 287−297.], it was proposed that the most critical reaction step in this process is the displacement of

Recent models have worked with the assumption that birds try to minimize either time, energy or predation risk during migration, or some combination of these. The few empirical studies available have suggested that time minimization may be the most common strategy. One way of distinguishing between strategies is to study the departure decisions of migrating birds. We supplied migrating European ro

Dinuclear carboxylate-bridged zinc complexes of one symmetric and one asymmetric phenolate-based ligand catalyse the transesterification of 2-hydroxypropyl-p-nitrophenyl phosphate (HPNP) at different rates, with an unsymmetrical complex being more active than a symmetric one.

A series of azapeptides as potential inhibitors of cysteine proteases were synthesized. Their structures, based on the binding center of cystatins, contain an azaglycine residue (Agly) in place of the evolutionarily conserved glycine residue in the N-terminal part of the enzyme binding region of cystatins. Incorporation of Agly should lead to deactivation of the acyl-enzyme complex formed against

The effect of strain and transforming growth factor beta on equine tendon fibroblasts (tenocytes) was assessed in vitro. Tenocytes were isolated from flexor and extensor tendons of horses from foetal to 10 years of age. These cells were cultured until confluent on collagen-coated silicone dishes. Cyclic biaxial strain of 9 +/- 1% was applied at 0.5 Hz for 24 hours with or without added TGFbeta1 or

Plant phenological development is orchestrated through subtle changes in photoperiod, temperature, soil moisture and nutrient availability. Presently, the exact timing of plant development stages and their response to climate and management practices are crudely represented in land surface models. As visual observations of phenology are laborious, there is a need to supplement long-term observatio

The observed increased risks of gastric cancer among first-generation immigrants compared to those in Swedes suggest the role of childhood environmental exposure in the risk of this disease.

The consecutive binding of two potassium ions to a bis(18-crown-6) analogue of Tröger’s base (BCETB) in water was studied by isothermal titration calorimetry using four different salts, KCl, KI, KSCN, and K2SO4. A counterintuitive result was observed: the enthalpy change associated with the binding of the second ion is more negative than that of the first (ΔH°bind,2 < ΔH°bind,1). This remarkable f

This study builds on analyses of everyday professional practices to explore de-bordering and re-bordering processes in the field of gender-based violence (GBV). The concepts of de-bordering and re-bordering practices express the tensions arising from the conflictual roles taken on by civil society actors (CSAs) in their double vest of service delivery for the state and advocate for migrant women w

This thesis examines how participant-made banners from the Strajk Kobiet protests in Poland re-appropriated national and religious symbols to challenge cultural narratives and offer alternative visions of Polishness and womanhood. Set against democratic backsliding and a strong state–Church alliance, the study focuses on five photographs from the Archive of Public Protests, selected for their enga

Universities offer a variety of services to students, staff, and affiliates, traditionally managed through physical campus cards. However, increasing mobility requirements and the need for secure, interoperable digital identity solutions call for a modernized approach to service access. This paper introduces eduTAP, an open-source concept and software framework that builds on top of digital wallet

Age estimation based on the dentition of animal remains is one of the most important methods used for analysis of the demography of past as well as contemporary animal populations by zooarchaeologists and wild game biologists (Wagenknecht 1967; Silver 1969; Morris 1972; Wilson et al. 1982). By constructing age profiles from faunal remains it is possible to study hunting of wild boar and pig husban

Correction to: Communications Materialshttps://doi.org/10.1038/s43246-025-00842-y, published online 5 June 2025 The authors have identified an error related to the discussion of the XPS results in this Article. We incorrectly assigned some XPS features in the Ni 2p spectra to Ni3+ (Figure 7a and 7d), associated to NiOOH. However, the spectra in panel 7a are associated to Ni(OH)2 with an oxidation

Hydrogen transfer reactions hold pivotal importance in organic synthesis by enabling selective bond formation, achieving redox-neutral transformations, and advancing sustainable methodologies. However, designing efficient catalytic systems for such reactions under mild conditions persists as a fundamental challenge in green chemistry. In this study, we present a controllable synthesis of defective

Three phases of archaeological investigations have been conducted in the area of the City Museum of Novi Sad at the Petrovaradin Fortress. In this study, we summarize the results of geoarchaeological research carried out during the third phase of excavations inside the museum building. The investigated area covered 27 m2. The approximately 0.60 m thick loessic sequence offers a unique opportunity
