Archaeometry, EarlyView.ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Los efectos producidos por la aproximación, colisión y subducción de dorsales pacíficas en los Andes Patagónicos [PDF]
Los Andes Patagónicos Septentrionales son una cordillera formada inicialmente por la subducción de las placas de Phoenix-Farallón y posteriormente por la de Nazca, que muestran rastros de deformación polifásica desde el Jurásico superior hasta el Neógeno,

Environmental justice in education for climate action: Case studies from Perú and Uganda
Children &Society, EarlyView.Abstract This paper draws on participatory research with secondary school learners in Perú and Uganda that shows how environmental and social (in) justices are interwoven and embedded in young people's experiences of the natural world. These experiences contrast with learners' accounts of environmental education in secondary schooling, in which the ...

Cell Proliferation, EarlyView.This review elucidates the intricate cellular signalling networks involved in high‐altitude pulmonary hypertension (HAPH), integrating canonical pathways like HIF, MAPK and BMP with emerging targets such as Wnt/β‐catenin, Notch, Hippo‐YAP and IL‐6. It highlights potential therapeutic strategies targeting these pathways to mitigate vascular remodelling ...

Ecological Entomology, EarlyView.First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

The FEBS Journal, EarlyView.Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.
