Traumatic brain injury (TBI) remains a major cause of neurological morbidity worldwide, and mild TBI (mTBI) is frequently associated with emotional disturbances, including anxiety-like behavior. Although classical mechanisms of secondary injury have been extensively characterized, metabolic alterations, particularly those involving cerebral lipid homeostasis, remain incompletely defined. Given the structural and regulatory rol...

Microplastics have been identified in hundreds of species, with evidence of trophic transfer via contaminated prey. Sarasota Bay common bottlenose dolphins ( Tursiops truncatus ) serve as sentinels of coastal pollution, including plastics and chemical plasticizers. Previous research confirmed microplastic ingestion in these dolphins (100.0%, n = 7) and extensive contamination in 11 common prey species (96.5%, n = 86). This stu...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Understanding how biodiversity responds to human‐caused environmental change represents a major scientific challenge. Among the biological processes underlying these responses, ageing plays a critical role by shaping individual life histories and, ultimately, demographic dynamics. Telomeres, the repetitive nucleotide sequences at the ends of linear chromosomes, are widely used biomarkers of ageing, as their length can be shape...

In May 2024, the International Tribunal for the Law of the Sea (ITLOS) published an advisory opinion on climate change. Many expected that this decision would help to clarify the balance between the paradigms of ocean protection and utilisation in the context of climate change. This is especially relevant for governing emerging marine carbon dioxide removal (mCDR) approaches being proposed to increase the carbon drawdown poten...

Recent studies have shown that a few tree species dominate abundance and carbon storage in undisturbed Amazonian forests. However, this pattern remains poorly understood in forests regrowing after deforestation. Understanding dominance patterns in secondary forests is important as it could improve insights into their functioning and guide management and restoration efforts. We used unweighted and novel plot‐weighted approaches...

Cancer is projected to become the leading cause of death in Brazil within the next decade. Despite this growing burden, oncology education remains inconsistently structured in undergraduate medical curricula, potentially limiting physicians’ preparedness for cancer care. To compare expectations and perceptions of oncology education between independent cohorts of first- and sixth-year medical students and to assess whether acad...
