Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Birch Rust Spore Exposure and Upper Airway Symptom Dynamics in a Subarctic Region: Indications for a Novel Seasonal Allergen

Clinical and Translational Allergy, Volume 16, Issue 8, August 2026.
ABSTRACT Background Airway allergies affect 20%–30% of the global population, with pollen and fungal spores representing major environmental triggers. Although fungal spores are far more abundant than pollen, their allergenic role—particularly from phytopathogenic rust fungi such as birch rust (BR)—remains poorly understood.

Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

EcoEnergy, Volume 4, Issue 4, August 2026.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Fuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood. Fuel treatments can reduce aboveground carbon storage and may also influence belowground carbon storage ...

Just Transition Toward Clean Energy Access With Focus on Lead‐Based Perovskite Solar Cell Technology: Lessons, Experiences, and Future Perspectives

Global Challenges, Volume 10, Issue 8, August 2026.
To intentionally mitigate energy poverty in underserved communities, advanced perovskite energy technologies such as lead‐based perovskite solar cells are necessary. However, in future deployment of these materials, energy justice, equity, inclusivity and environmental sustainability must be taken into account.
