Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

A South African Language Teacher Educator's Reflective Journey Through Sociocultural Theory and Asset‐Based Mediation

TESOL Quarterly, EarlyView.
Abstract This reflective article chronicles a South African English as a Medium of Instruction (EMI) university teacher educator's journey from professional disillusionment toward a more intentional, transformative praxis. The catalyst for this journey was the recurring observation of novice teachers abandoning dialogic, asset‐based pedagogies learned ...

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global change and associated disturbances are increasing the risk of regeneration failure for tree species in temperate forests. Seedlings are particularly vulnerable to water stress due to their shallow root systems, making below‐ground plasticity a potentially key ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

The Early Upper Palaeolithic in British caves: problems and potential Le Paléolithique supérieur ancien dans les grottes de Grande‐Bretagne : problèmes et potentiels

Journal of the Royal Anthropological Institute, EarlyView.
Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.
