Nuclear applications in insect pest control: SIT for mosquitoes, vectors of human diseases
(2023) Yamada, Hanano
Mosquitoes are still the most significant killers on earth, as they transmit malaria and numerous arboviral diseases worldwide. Although significant efforts have been made to manage the spread and growth of mosquito vector populations, many conventional control tools have been proven ineffective, insufficient, or unsustainable, and alternative methods are needed to reach and maintain low vector densities to break the transmission cycle. The sterile insect technique (SIT) has been proposed as an additional tool to add to the area-wide integrated pest management (AW-IPM) strategy for the improved and sustainable management of mosquito vectors, as this technique has been shown highly effective against other insect pests by enabling total population control [1,2] The essential components of the SIT include the mass rearing of the target species, the selection and reproductive sterilization of males, and their inundatory release into the target population, where successful copulation with wild females results in no offspring and consequently decreases the population size in subsequent generations. Key factors that influence the males’ success in reducing the population size in the field include the level of sterility in the male mosquito and the biological quality and aptitude required for mating success once released [2].
Various methods have been used for achieving reproductive sterility in mosquitoes in the context of the sterile insect technique (SIT), such as the use of chemosterilants [3–9] or by modifying the insect’s DNA [10–16]. However, the dominant approach for the SIT for most insect species is sterilization by exposure to ionizing radiation [1]. Most commonly, 60Cobalt or 137Caesium irradiators have been used for this purpose. More recently, the suitability of self-shielded X-ray irradiators as an alternative for sterilizing mosquitoes has been investigated [17,18]. However, a thorough evaluation should be performed on alternative devices before recommendations for the SIT can be made.
For the characterization of irradiators, including mapping the dose distribution in the irradiation chamber or the sample being irradiated, and for routine or experimental irradiation, dosimetry is an indispensable component of irradiation quality assurance. Therefore, a standardized, reliable dosimetry system is required for the work presented in this thesis and is the topic of the first chapter.
In response to reports from numerous SIT projects aimed to manage mosquito vectors that provided highly variable results regarding doses needed to achieve at least 99% induced sterility in the males, various endogenous and exogenous factors that could affect dose-response in the mosquitoes were assessed. The results indicated that the strain’s geographic origin and pupal size did not affect dose-response. In contrast, pupal age, atmospheric conditions (hypoxia/anoxia), cold temperatures, irradiation dose rate, and sample preparation methods affected irradiation outcome. The realization following this series of experiments is that it will be logistically tedious to control for pupal age, and even more so to control the dissolved oxygen levels when irradiating large numbers of pupae in water.
Thus, the focus of the studies shifted to irradiation at the adult stage to overcome these issues, develop improved, standardized protocols for mosquito sterilization, and investigate irradiation protocols that may improve sterile male quality.
The final chapter of this work describes the application potential of an “off-the-shelf” blood X-ray irradiator as an alternative to self-shielded gamma irradiators for use in SIT programs. Careful dose rate measurements and dose mapping of the irradiation chamber showed an excellent dose uniformity and a sufficient processing capacity, capable of sterilizing 75 million adult Aedes mosquitoes week, proposing this technology a helpful tool and improvement for mosquitoes SIT programs in the future.
Xammlung – Antike Objekte treffen auf zeitgenössische Perspektiven
(2025) Künstlergruppe Guirlanden
Am 09. Oktober 2025 eröffnet die dänische KünstlerInnengruppe Guirlanden in Kooperation mit der Antikensammlung der JLU Gießen eine experimentelle Kunstausstellung, die antike Objekte mit zeitgenössischer Kunst in Dialog setzt. Die Ausstellung lädt BesucherInnen ein, die Antike in modernen Rezeptionen und unterschiedlichen Medien neu zu entdecken. Das „X“ im Titel symbolisiert dabei die Schnittstelle, an der Antike und Moderne aufeinandertreffen: historische Objekte und aktuelle Sichtweisen treten in Wechselwirkung und eröffnen neue Perspektiven über die Grenzen von Zeit, Medium und Interpretation hinweg.
Die ortsspezifischen Werke der KünstlerInnen greifen zentrale Themen der antiken Kunst und Kultur auf – von Alphabet, Architektur und Kleidung über Theater und Metamorphose bis hin zu Fragmentierung, Skulptur und Zeit. Mit Materialien wie Keramik, Tusche, Stoff, Lichtprojektionen, Fotografie, Klang, 3D-Scans und digitalen Medien wie ChatGPT werden diese Themen neu interpretiert und in die Gegenwart transportiert.
Ausstellung basiert auf Objekten der Antikensammlung der Justus-Liebig-Universität Gießen. Mit über 5.000 Artefakten – darunter Vasen, Terrakotten, Reliefs, Statuetten, Münzen und römische Gläser – vermittelt die Sammlung, von der eine repräsentative Auswahl im Museum für Gießen in wechselnden Sonderausstellungen öffentlich präsentiert wird, Einblicke in rund 3.000 Jahre antiker Kultur: von Götterwelt, Theater und Bestattungssitten bis hin zu Schriftkultur und Alltagsleben. Bedeutende Wissenschaftlerinnen wie Margarete Bieber, Pionierin der antiken Theater- und Trachtenforschung, prägten die Sammlungsgeschichte. In der Ausstellung werden Objekte der Sammlung zum Teil in Form von 3D-Replikaten Bestandteile der neu geschaffenen Kunstwerke.
Opportunistic Acinetobacter baumannii and Acinetobacter sp. Isolates in Rural and Urban Wastewater Treatment Plants and Raw Manure and Biogas Digestates
(2025) Pulami, Dipen
Genus Acinetobacter is diverse, and multi-drug resistant (MDR) Acinetobacter linked infections are problematic. Studies hitherto performed in extra-clinical settings, such as biogas plants (BGPs) and wastewater treatment plants (WWTPs), lacked diversity and antimicrobial resistance (AMR) of Acinetobacter. This thesis studied the diversity and AMR of Acinetobacter in livestock manure, BGP digestates, a rural WWTP, and two urban WWTPs (receiving hospital/veterinary sewage), including upstream/downstream from the river receiving effluent located in Germany. Partial 16S rRNA/rpoB genes-based study showed highest diversity (8/14, phylotypes) in urban WWTPs influent. A. baumannii were found in manure, digestate and all stages of rural WWTP (except river upstream). BGPs and rural WWTP had novel sequence-types (18/23, STs) susceptible to antimicrobials—indicating these niches consisted diverse Acinetobacter. In urban WWTPs, Acinetobacter were also isolated from secondary sludge and anaerobic post-digestor filtrate, and mostly showed MDR phenotypes against carbapenems, colistin and ciprofloxacin, suggesting hospital waste inflow into WWTPs influenced their AMR profile and clinical relevance. Isolation of Acinetobacter from digestate, and treated sludge/anaerobic post-digestor filtrate indicated their survival in anaerobic condition, which was supported by the presence of genes encoding AMP phosphotransferase and adenylate kinase linked to processing of polyphosphates for energy. Comparative genomics of A. bohemicus strains from pig manure (QAC-21b, this study) and textile dying pond (KCTC 42081, Abbas et al. 2014) showed higher genomic contents of transposons/insertion elements, and genomic islands suggesting their adaptation to these environments containing quaternary alkyl ammonium compounds (QAACs), compared to type strain ANC 3994T (forest soil, Krizova et al. 2014). Considering Acinetobacter genome plasticity, the likelihood of selection/spread of AMR if released into environment via manure (sludge) must not be neglected. Experiments with Acinetobacters from various sources will help understand this process. Plant colonization study can provide insights into potential interactions in the rhizosphere and phyllosphere, revealing routes of Acinetobacter transmission to humans. Taking “One-Health” approach, future Acinetobacter genome comparison from different sources might help understanding evolution and adaptation from extra-clinical to clinical settings. This could help development of intervention strategies to control AMR spread in non-clinical environments.

Illiberal SCRIPTS Dataset: Corpus-Based Analysis of Norm Diffusion across Post-Soviet Regional Organisations (CIS, CSTO, SCO)
(2025) Nasibov, Murad; Gawrich, Andrea
This dataset accompanies the book chapter "Scripts in Circulation: Cross-Pollination of Anti-Liberal Norms in Eurasian Regionalism" (Gawrich & Nasibov, In: Panke, Diana; Libman, Alexander; Börzel, Tanja: Contestations of the Liberal Script in Regional Organizations in the Global South and the Global North. Oxford University Press (Forthcoming)).
It provides all reproducible analytical artefacts derived from declaratory documents of three intergovernmental organisations – the Commonwealth of Independent States (CIS), the Collective Security Treaty Organisation (CSTO), and the Shanghai Cooperation Organisation (SCO) – covering the period 2002–2024.
The dataset excludes verbatim text for copyright reasons and instead offers fully processed linguistic and statistical representations that enable complete replication of the study’s computational findings.
The analysis conceptualises “script cross-pollination” as the diffusion of illiberal normative vocabularies – such as sovereignty, stability, multipolarity, and non-interference – across regional organisations in post-Soviet Eurasia.
Using a transparent R-based pipeline, the study lemmatises and tokenises Russian-language summit declarations, constructs document–feature matrices and TF–IDF representations, and computes time-series trends, inter-organisational cosine similarity, and lead–follow diffusion patterns.
The dataset demonstrates how illiberal normative repertoires migrate, stabilise, and co-evolve across Eurasian organisations, showing that these institutions function as discursive relay stations of a shared counter-liberal script rather than as isolated challengers of liberal order.
All processing and analytical steps are documented in the included file illiberal_scripts_pipeline_public.R and further explained in HOW_TO_USE_outputs_README.md.
