Signatures of Radiation‐Induced Stress and Putative Selection on Immune Targets in Chornobyl Wolves

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Investigating the physiological and evolutionary consequences of contaminant exposure in wild populations is critical for understanding long‐term ecological impacts of anthropogenic change. However, how and why species persist, even thrive, in highly contaminated regions in the absence of humans remains a topic of much debate.

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

Detecting Thunderstorm‐Related High‐Energy Phenomena in Weak Signals

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Gamma‐ray glows (GRGs) are high‐energy events associated with thunderstorms, characterized by an enhancement of the high‐energy background radiation lasting from a few seconds to several minutes. They are typically detected near their sources by balloons, aircraft, mountain‐based observatories, or at sea level in regions where thunderstorms ...

DETERMINATION OF EXTERNAL IRRADIATION FROM SOURCES WITH COMPLEX GEOMETRY CONTAINING RADIOACTIVE WASTE

open access: yesEast European Journal of Physics, 2016
A combined technique using both Monte-Carlo and quasi-analytic method has been developed for calculation of irradiation from complex objects containing radioactive waste. Monte Carlo method is used to calculate spectral, angular and spatial distributions

Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...

A Graph Signal Processing Approach to the Characterization of Xe‐133 Atmospheric Background

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The geopolitical context advocates for monitoring nuclear activities within an international framework. In this context, the Comprehensive Nuclear‐Test‐Ban Treaty Organization has established measurement stations, known as the International Measurement System (IMS).

Radioiodination of Two Carborane‐Based Dual Cyclooxygenase‐2/5‐Lipoxygenase Inhibitors and Their In Vitro and In Vivo Evaluation

open access: yesChemBioChem, Volume 27, Issue 7, 14 April 2026.
Two dicarbadodecaborane(12)‐based dual cyclooxygenase‐2/5‐lipoxygenase (COX‐2/5‐LO) inhibitors were 123I‐labeled. Refinement of labeling and formulation conditions and extensive in vitro characterization are presented. Cell uptake studies in COX‐2‐ and 5‐LO‐overexpressing cell lines showed COX‐2‐independent and partly 5‐LO‐dependent uptake.
