On the Origin of the Brain Semi‐Heavy Water Deuterium MR Signal Following Administration of Deuterated Metabolic Substrate: A Cautionary Tale

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 862-870, August 2026.
ABSTRACT Purpose To evaluate the extent to which the appearance of HOD in the brain following systemic administration of a deuterated substrate is due to local brain metabolism versus body metabolism. Methods [6,6‐2H2]glucose, which is transported across the blood‐brain barrier (BBB), and [6,6‐2H2]fructose (Fruc), which does not cross the BBB, were ...

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1749-1765, July 2026.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

Contrasting CO2‐response strategies in Pardina lentils: Yield maximization in a commercial cultivar and seed composition adjustment in a landrace

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 9, Page 5422-5436, July 2026.
Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...

How Do Transnational Ties Shape Migration Aspirations?

open access: yesPopulation, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT People with family or friends abroad are more inclined to migrate. But why is this so? Perhaps people with transnational ties have a rosier view of life as a migrant, or maybe it is remittances, specifically, that work as tangible proof of opportunities abroad. Or perhaps subconscious comparisons with migrants result in lower satisfaction with

Epistemic Objects and Tools on the School Grounds: Addressing Plant Blindness and Knowledge Construction

open access: yesScience Education, Volume 110, Issue 4, Page 1152-1168, July 2026.
ABSTRACT Plants mediate the supply of energy and matter for all animals, including human beings yet we are faced with “plant blindness” whereby we pay limited attention to and accord little value to plants. Plant blindness is evident in school curricula whereby students have limited opportunities to learn about plants.

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice

open access: yesAnnals of Applied Biology, Volume 189, Issue 1, July 2026.
Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Post‐disaster deterritorialisation and ‘roof‐centred’ recovery: enduring policy impacts on marginalised groups in Brazil

open access: yesDisasters, Volume 50, Issue 3, July 2026.
Abstract This study critically examines post‐disaster recovery policies in Brazil and their short‐ and long‐term effects on marginalised populations, particularly those living in informal or precarious housing. Drawing on a mixed‐methods investigation conducted in collaboration with the Movimento dos Atingidos por Barragens, the research analyses multi‐
