Beneath the buzz: Quantifying nest locations and densities of ground‐nesting wild bees (Hymenoptera: Anthophila)

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 7, Page 1334-1349, July 2025.
Abstract Wild bees (Hymenoptera: Anthophila) are important pollinators and essential for maintaining ecosystem health. The majority of bee species are ground‐nesting, and all bees spend most of their lifetime inside the nest. Still, most studies and monitoring schemes assess wild bees during flower visitation, allowing no conclusion about their nest ...

Increased aeolian activity linked to Neoglacial cooling and glacier advance in southern Greenland

open access: yesBoreas, Volume 54, Issue 3, Page 382-394, July 2025.
Intense aeolian activity observed in the Igaliku Kujalleq records in S Greenland is not related to Norse activities. Instead, we suggest that changes in the North Atlantic atmospheric circulation pattern combined with Neoglacial glacier advances led to increased katabatic wind activity and triggered increased aeolian activity from large outwash plains.

Approach to the Management of Gastrointestinal Manifestations in Patients With Phaeochromocytoma and Paraganglioma

open access: yesClinical Endocrinology, Volume 103, Issue 1, Page 21-35, July 2025.
ABSTRACT Objective Managing gastrointestinal symptoms in patients with phaeochromocytoma and paraganglioma (PPGL) is challenging due to the risk of catecholaminergic crisis with many commonly prescribed medications, especially in functional tumours.

Evaluation of [18F]PSMA‐1007 uptake variability in patients with prostate cancer

open access: yesClinical Physiology and Functional Imaging, Volume 45, Issue 4, July 2025.
Abstract Background The biodistribution of PSMA‐ligands is of interest in radionuclide therapy planning. We investigated the variability of [18F]PSMA‐1007 uptake in organs at risk and in relation to tumour burden in prostate cancer patients. Methods A total of 1086 patients who underwent PSMA PET‐CT for staging or recurrence of prostate cancer were ...

Myocardial perfusion imaging in advanced coronary artery disease

open access: yesEuropean Journal of Clinical Investigation, Volume 55, Issue 7, July 2025.
Myocardial perfusion imaging in advanced coronary artery disease. This review focusses on the utility of MPI by means of CMR, SPECT and PET, in patients with advanced CAD—the latter characterized by documented CAD (i.e. MI and/or PCI, prior CABG or the presence of a CTO).

Field‐assisted processing of Ce–zirconolite ceramics for nuclear applications

open access: yesInternational Journal of Applied Ceramic Technology, Volume 22, Issue 4, July/August 2025.
Field‐assisted processing of zirconolite ceramics resulted in significant reduction in time and energy compared to conventional processing. Abstract Conventional, flash, and hybrid sintering (unique combination of conventional and microwave heating) experiments were performed on 10% Ce‐doped zirconolite samples and the results were compared.

Effect of cement water contacting an aged cementitious grout on the dissolution rates of inactive nuclear glass SON68

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
Abstract The long‐term behavior of high‐level radioactive waste glass depends on the mineralogical and geochemical interactions between the various components of the multibarrier system, under geological repository conditions. The present study focuses on SON68 glass alteration in synthetic cement water and at 50°C and 70°C.

Tracking landslide sediment: 10Be dilution of detrital quartz in multiple grain sizes following the 2016 Mw 7.8 Kaikōura earthquake, New Zealand

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.
We found that the in‐situ 10Be concentration in multiple grain sizes can be correlated to the sediment fluxes derived from geomorphic change detection. Our results show that the magnitude of 10Be dilution relates to landslide volume, post‐seismic hillslope delivery and degree of mixing. Although the 10Be dilution factor has little to no relationship to

Fluorescent Deferoxamine Complexes of Cu(II) and Zr(IV): Insights in the Development of Dual Imaging Probes

open access: yesChemistry – A European Journal, Volume 31, Issue 35, June 23, 2025.
The insertion of a fluorescent coumarin unit by using a lysine‐based linker on deferoxamine leads to a chelating agent (DFOKC), whose Cu(II) and Zr(IV) complexes can be used for both optical imaging and positron emission tomography. DFOKC shows increased binding ability for Cu(II) and Zr(II) and improved tumor cell internalization via pinocytosis ...
