Host dispersal relaxes selective pressures in rafting microbiomes and triggers successional changes.

What little we know about how microbiomes change over the course of host dispersal has been gleaned from simulations or snapshot sampling of microbiomes of hosts undertaking regular, cyclical migrations. These studies suggest that major changes in both microbiome richness and turnover occur in response to long-distance movements, but we do not yet know how rare or sporadic dispersal events for non-migratory organisms might affect the microbiomes of their hosts. Here we directly examine the microbiomes of rafting seaweed, leveraging host genomic analyses, amplicon sequencing, and oceanographic modelling to study the impacts of ecological dispersal of hosts on their microbiomes.

Scholars in Health Equity: A Program of Structured Physician Faculty Development.

Background: Structured faculty development programs focused on integrating health equity into medical education curricula remain limited.

Aim: To describe an interdisciplinary faculty development program grounded in adult learning theory and to assess its impact on participants' professional growth.

Setting And Participants: Twenty-one faculty members across six academic-affiliated health systems.

Heterogeneity in pediatric resting EEG data processing and analysis: A state of the field.

Developmental, resting electroencephalography (EEG) is gaining rapid popularity with implementation in large-scale studies as well as a recent WHO report naming resting EEG as a gold standard measure of brain health. With an increased interest in resting EEG as a potential biomarker for neurocognition, it is paramount that resting EEG findings are reliable and reproducible. One of the major threats to replicability and reproducibility stems from variations in preprocessing and analysis.

Microplastic pollution in marine sediments of the Antarctic coastal environment of Potter Cove and nearby areas (25 de Mayo/King George Island, South Shetlands).

Plastic contamination in the Southern Ocean is a growing issue. This study provides the first comprehensive analysis of marine microplastics (MPs) (0.1-5 mm) in surface sediments in Potter Cove and nearby areas around Argentina's Carlini station (25 de Mayo/King George Island, South Shetlands).
