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.

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.

Article Synopsis
  • Three aminocarbonyl compounds were created and analyzed for their light-emitting properties in different solvent polarities.
  • The study revealed significant inverted solvatofluorochromism, where the emission energy changes based on the solvent used.
  • This inversion happens at moderate polarities and is caused by a shift in how the solute interacts with the solvent, impacting the stability of the excited state of the dyes.

Article Synopsis
  • Age and IGF-1 levels are inversely related to cognitive decline and dementia, suggesting that higher IGF-1 may protect against these issues.
  • IGF-1 plays important roles in brain development and function, supporting processes like neurogenesis, inflammation reduction, and synaptic formation through its signaling pathways.
  • Studies in rodents and clinical research indicate that higher IGF-1 levels correlate with improved cognitive performance, while lowered IGF-1 can lead to cognitive impairments.

The error-related negativity (ERN)-an index of error monitoring-is associated with anxiety symptomatology. Although recent work suggests associations between the ERN and anxiety are relatively modest, little attention has been paid to how variation in task parameters may influence the strength of ERN-anxiety associations. To close this gap, the current meta-analysis assesses the possible influence of task parameter variation in the Flanker task-the most commonly used task to elicit the ERN-on observed ERN-anxiety associations.

Children with a history of behaviorally inhibited (BI) temperament face a heightened risk for anxiety disorders and often use control strategies that are less planful. Although these relations have been observed concurrently in early childhood, middle childhood, and adolescence, few studies leverage longitudinal data to examine long-term prospective relations between cognitive control and anxiety. Using longitudinal data from 149 adolescents (55% female; from predominantly White middle-class families), we assessed temperament in toddlerhood and cognitive control and anxiety at 4, 12, 15, and 18 years of age.
