Safe management of nuclear legacies arising from past activities is a critical issue in maintaining confidence for the continuing and future use of radioactive materials. Effective and efficient regulatory supervision of nuclear legacy management is a critical part of that process. The Norwegian Radiation Protection Authority plays an active role in bilateral regulatory cooperation projects with sister authorities in the Russian Federation, as part of Norway's Plan of Action to improve radiation and nuclear safety. Based on this experience and by reference to specific legacy sites and facilities, this study provides an overview of the substantial progress made in remediation at the Site of Temporary Storage for spent fuel and radioactive waste at Andreeva Bay and presents radiation protection issues arising from the experience and lessons learned in this work. It is suggested that this experience can be useful in the further development of international recommendations, standards and guidance on remediation of nuclear legacies.

Overgrazing is the primary human-induced cause of soil degradation in the Caatinga biome, intensely threatening lands vulnerable to desertification. Grazing exclusion, a simple and cost-effective practice, could restore soils' ecological functions. However, comprehensive insights into the effects of overgrazing and grazing exclusion on Caatinga soils' multifunctionality are lacking.

(1) Background: Alternative antibiotics are needed to treat infective endocarditis (IE) caused by non-/non- enterococci; we aimed to assess the in vitro activity of ampicillin plus ceftriaxone (AMP + CTR) against these enterococci and to describe its clinical efficacy in IE cases. (2) Methods: Time-kill curves with standard (ISI) and high (IHI) inocula were performed to test isolates [3 (ECAS) and 1 (EGALL)] and non- isolates [1 (EDUR), 1 (EHIR) and 1 (ERAF)]. The narrative literature review of IE cases treated with AMP + CTR was analyzed alongside three study cases.

The extensive presence of per-/polyfluoroalkyl substances (PFASs) in the environment and their adverse effects on organisms have garnered increasing concern. With the shift of industrial development from legacy to emerging PFASs, expanding the understanding of molecular responses to legacy and emerging PFASs is essential to accurately assess their risks to organisms. Compared with traditional toxicological approaches, omics technologies including transcriptomics, proteomics, metabolomics/lipidomics, and microbiomics allow comprehensive analysis of the molecular changes that occur in organisms after PFAS exposure.

The ease with which genome-wide data can nowadays be collected allows complicated phylogenetic questions to be re-evaluated. Phylogenetic relationships among newts have often proven difficult to resolve due to the prevalence of incomplete lineage sorting and introgressive hybridization. For the newt genus Lissotriton, phylogenetic relationships are not settled and there is controversy surrounding the species status of several taxa.

Unlabelled: and are recognized as significant opportunistic pathogens affecting aquatic animals and humans. However, their infections in amphibians are poorly documented, and their pathogenicity to the Chinese spiny frog () remains unexplored. This study investigated an outbreak of putrid-skin disease among on a farm in Lishui City, Zhejiang Province, China.
