КОЛЕБАНИЯ ЛЕДНИКА КАШКАТАШ В XVII–XXI ВВ. ПО КАРТОГРАФИЧЕСКИМ, ДЕНДРОХРОНОЛОГИЧЕСКИМ И ЛИХЕНОМЕТРИЧЕСКИМ ДАННЫМ

open access: yes, 2015
We focused our study on the retreat of a typical valley glacier Kashkatash, located in the Elbrus Area. We compared the old photographs of the glacier forefields (H. Burmester, 1911; H. Altberg, 1927; E.N.

Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

open access: yesChemFoodChem, Volume 2, Issue 2, June 2026.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

open access: yesEarth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

Analysing recent spatial and temporal atmospheric methane variations using forward and inverse modelling [PDF]

open access: yes, 2011
The TOMCAT 3-D chemical transport model (CTM) has been used to investigate the cause of recent variations in global atmospheric methane (CH4), focusing on examining changes in the balance of sources and sinks of the species.

Differential Health Impacts of Short‐Term Particulate Matter Exposure in Arid and Semi‐Arid Regions: A Scoping Review

open access: yesGeoHealth, Volume 10, Issue 6, June 2026.
Abstract Particulate matter (PM) exposure is a leading risk factor for cardiovascular and respiratory morbidity and mortality across the world. While arid and semi‐arid regions account for more than 40% of terrestrial land, there is a paucity of research investigating the relationship between PM exposure and health outcomes or how risk varies across ...

Comparing Solar Structure Detection Methods in SDO/AIA Observations and the Application to Raw Uncalibrated Data

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Recent advances in solar physics increasingly rely on automated identification of coronal structures using machine learning. Yet most studies emphasize scientific performance without evaluating feasibility for onboard deployment to prioritize downlink observations.

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...
