Environmental DNA as a complementary tool for biodiversity monitoring: A multi-technique and multi-trophic approach to investigate cetacean distribution and feeding ecology

This study uses environmental DNA to characterize cetacean communities and their prey in coastal waters, finding similar results to visual surveys and identifying year-round presence.

Phenotypic architecture of sociality and its associated genetic polymorphisms in zebrafish

This study identifies two independent components of sociality in zebrafish, social tendency and social recognition, and finds that only social tendency is associated with genetic polymorphisms in candidate 'social' genes.

Mapping the microbial diversity and natural resistome of North Antarctica soils

This study investigates the microbial diversity and resistome of North Antarctica soils, identifying a diverse natural resistome with ARGs hosted in mobile genetic elements.

Copper nanoparticles prompt the activity of estuarine denitrifying bacterial communities at relevant environmental concentrations

This study shows that copper nanoparticles increase gene expression and denitrification rates in estuarine sediments at environmentally relevant concentrations.

Forward genetics in Wolbachia: Regulation of Wolbachia proliferation by the amplification and deletion of an addictive genomic island

This paper identifies two Wolbachia mutants with altered proliferation rates, showing that Octomom copy number affects proliferation, host lifespan, and antiviral protection.

Intra-individual variability of sleep and nocturnal cardiac autonomic activity in elite female soccer players during an international tournament

This study examines sleep patterns and nocturnal cardiac autonomic activity in elite female soccer players during a tournament, finding significant individual variability in sleep duration and heart rate variability.

Preprint: Environmentally-Friendly Workflow Based on Supercritical Fluid Chromatography and Tandem Mass Spectrometry Molecular Networking For the Discovery of Potent Anti-Viral Leads From Plants

This paper develops a supercritical fluid chromatography and tandem mass spectrometry workflow to isolate and identify antiviral compounds from plant extracts, discovering two potent antiviral diterpene esters.
