Late Holocene environmental dynamics and their influence on human occupation in the Santiago basin (33°S), Central Chile

Fluvial-alluvial deposits provide high-resolution records for reconstructing paleoenvironments and deciphering archaeological site-formation processes. Despite their prevalence in the Mediterranean-climate region of central Chile, a significant research gap persists in linking pr...

Genomic detection of highly pathogenic avian influenza H5N1 in Antarctic seabirds reveals connectivity with South American viral lineages

Abstract Emerging avian viruses increasingly threaten Antarctic wildlife, raising concerns about ecosystem health and biodiversity. In this study, we conducted a comprehensive investigation of avian influenza virus (influenza A virus, IAV) in both resident and migratory birds inh...

Transient cartilages and interdigital vasculature organization in the embryonic duck foot

Abstract The evolution of webbed limbs represents a recurrent adaptation to aquatic life in tetrapods, facilitated by the dynamics of embryonic digit development. Digits form at the distal tip of the limb bud as cartilage condensations surrounded by mesenchymal cells, a process d...

Dust Substructures and Line Perturbations driven by a Forming Planet in J16120

Abstract Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and Hα observations. In this work, we present new evidence for ongoing planet formation based on Atacama Large Millime...

Search for axions and dark photons using single molecule magnets

Molecular magnets, although analogous to familiar macroscopic magnets, offer a platform for next generation magnetic storage technologies with far higher data densities and prospective applications in quantum information science. When exposed to an external magnetic field, single...

Occurrence and Characterization of Graft-Transmissible Pathogens of Citrus in Orchards and Urban Citrus in Chile with a Focus on the Apscaviroid nanocitri

Apscaviroid nanocitri (citrus dwarfing viroid, CDVd) is a graft-transmissible pathogen that frequently coexists with other citrus viroids and affects tree vigor. This study evaluated the occurrence of citrus viroids in small growers and commercial orchards in Chile and characteri...

Rhodococcus erythropolis ICBD2 membrane and cell wall adaptation to long-chain alkane degradation

Abstract Long-chain hydrocarbon biodegradation is limited by its low bioavailability. Specific strains degrade hydrocarbons including long-chain alkanes. Rhodococcus erythropolis ICBD2 is a hydrocarbonoclastic bacterium isolated from a chronically petroleum-contaminated coastal s...

Functional partitioning among core and peripheral bacteria shapes the giant kelp holobiont

The giant kelp Macrocystis pyrifera hosts diverse microbial communities integral to its ecological function, yet the distribution of microbial functions across different holobionts remains poorly resolved. Here, we used genome-resolved metagenomics to examine how microbial occupa...

A Governed NL-to-SQL Architecture for Reliable Clinical Data Querying and Outpatient Schedule Monitoring

The deployment of natural-language-to-SQL (NL-to-SQL) systems in primary healthcare requires more than accurate query generation: it also requires governed data access, robustness to local terminology, and reliable handling of ambiguous user requests. This study evaluated a pilot...
