Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Development and Characterization of ZnO‐Filled and Maleic Anhydride‐Compatibilized PP/SEBS Blends for 3D‐Printing Filaments

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 29, August 5, 2026.
PP/SEBS/MA/ZnO filaments produced by bench‐top single‐screw extrusion show refined morphology, increased crystallinity, improved thermal robustness, and preliminary FFF printability, demonstrating a practical route for functional filament development. ABSTRACT Currently, single‐screw extrusion offers a versatile and accessible route to produce polymer ...

Clinical Characterization of Patients With 5q Spinal Muscular Atrophy Types 2 and 3 in Brazil: A Cross‐Sectional Observational Study

open access: yesClinical Genetics, Volume 110, Issue 2, Page 172-188, August 2026.
This study describes the clinical heterogeneity of Brazilian patients with 5q spinal muscular atrophy types 2 and 3, highlighting prolonged diagnostic delays and the impact of disease duration on motor function. Early genetic diagnosis and access to multidisciplinary care are crucial to preserve functional outcomes.

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

Diel and Artificial Light Effects on Nearshore Communities Revealed by eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 4, July‐August 2026.
Environmental DNA revealed rapid, taxon‐specific community reorganization across diel and artificial light conditions in a nearshore marine ecosystem. Distinct responses among trophic groups indicate that artificial light at night reshapes predator–prey interactions and community structure within 30 min of exposure.
