Aerographite vsGraphite: Investigating the Role ofElectrode Architecture in H2-Mediated ElectroautotrophicBiofilms

Abstract Oxic microbial electrosynthesis using aerobic hydrogenotrophic bacteria requires productive cathodic biofilm formation, yet reactive oxygen species (ROS) generated at the electrode surface present a critical barrier to initial colonization. This study investigates biofil...

What constitutes successful collaborative conjecturing-and-proving processes? Relations between beginning undergraduates’ resources, conjecturing-and-proving processes, and performance

Abstract Students’ difficulties with mathematical argumentation, conjecturing, and proving, as well as with collaborating effectively, have long been documented in the literature. While there is some research on what constitutes successful proving processes, systematic investigat...

“We could do more”: exploring violance prevention measures in German outpatient primary care — a qualitative study

Healthcare workers in general practice are exposed to verbal and physical violence from patients and accompanying persons. While research has predominantly focused on hospital settings, evidence on violence prevention in primary care remains limited. General practice staff often...

PanEuCOPT-01: Photodynamic Inactivation of fungal mycelial spheres of plant-pathogenic Botrytis cinerea

This protocol describes an assay for Photodynamic Inactivation of the plant-pathogenic filamentous fungal species Botrytis cinerea. Grey mold ( B. cinerea ) occurs worldwide and affects over 200 different crops. Several resistant strains of the species have been collected on fiel...

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited d...

Groundwater Variability Is Strongly Linked to Soil Temperature Across Global Aquifers

Abstract Groundwater plays a critical role in land‐atmosphere interactions by regulating soil moisture and surface energy fluxes, yet its contribution to land‐surface processes and heat extremes remains poorly quantified globally. Here, we combine observation‐based aquifer record...

Current Techniques for Inorganic Polyphosphate Detection and Characterisation

Polyphosphate (polyP) is an evolutionarily conserved linear polymer of orthophosphate residues with diverse functions across organisms from bacteria to mammals. In addition to its roles in phosphate and energy storage, polyP has been implicated in thrombosis, inflammation, cancer...

The Hamburg Method for active cities: a multi-level framework for evidence-based urban physical activity promotion

Abstract Physical inactivity is a persistent global public health challenge, particularly in urban settings where complex social, environmental, and infrastructural factors shape opportunities for physical activity. Despite extensive evidence on effective interventions, a persist...

Felt and expressed needs regarding occupational health services from the perspective of micro-, small and medium-sized enterprises: a scoping review

BACKGROUND: In the context of the changing need for health care and prevention due to climate, digital and demographic change, occupational health services are of enormous relevance, as many people can be reached. Of particular interest are the occupational health services in mic...

Not all West Nile virus lineages behave alike: dose-response differences between lineages 1 and 2

Abstract The globally distributed arbovirus West Nile virus (WNV) is expanding across Europe, with rising numbers of human cases and an increasingly broad geographic distribution. Transmitted primarily by Culex mosquitoes, WNV lineages 1 and 2 are pathogenic to humans, yet their...

Vancomycin optimised dosing regimens for critically ill patients receiving renal replacement therapy

Optimal dosing of vancomycin in critically ill patients receiving renal replacement therapy (RRT) is uncertain due to high pharmacokinetic variability. We aimed to develop individualised vancomycin dosing recommendations that optimise efficacy while minimising toxicity. Prospecti...

“Norman… I Hate to Talk About Norman”: The Art of the Insult and Literary Friendship, Circa 1960

The essay rereads the literary field of the mid-twentieth century as structured by “the art of the insult”—a game the literati, exemplified by James Baldwin and Norman Mailer, are invested in. In essays and interviews, these writers engage in ad hominem verbal attacks to test the...

Differences in health outcomes of orthopedic rehabilitation after hip or knee replacement: a prospective pilot study benchmarking 23 rehabilitation facilities using Patient-Reported Outcome Measures (PROMs)

Abstract Background Patient-reported outcome measures (PROMs) are increasingly used for benchmarking hip and knee arthroplasty, yet evidence on their feasibility for public reporting of short-term rehabilitation outcomes remains limited. International initiatives such as ICHOM re...

β1- and β2-adrenergic receptor mediated spontaneous contractions and ryanodine receptor channel opening in human failing heart

Abstract In heart failure, β-adrenergic receptor (β-AR)-Gsα-cAMP-protein kinase A (PKA) signalling predisposes to delayed-afterdepolarisation-mediated arrhythmias. Phosphodiesterases (PDEs) hydrolyse cAMP, and PDE3 restrains β 1 -AR, β 2 -AR-mediated inotropic responses in failin...

The emergence of hybrid super-resolution microscopy

Abstract Super-resolution microscopy (SRM) has transformed biological imaging, yet many techniques remain constrained by limited accessibility. Expansion Microscopy (ExM) and fluorescence fluctuation-based super-resolution microscopy (FF-SRM) methods provide complementary strateg...
