When landing, Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot and claw kinematics become surface-specific upon touchdown to successfully grasp the perch.
A neuroanatomical analysis of Rimicaris exoculata provides insights into these animal’s brain architecture to illustrate possible adaptations to the hydrothermal vent habitat with its extreme physicochemical conditions.
Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.
An internet-based cohort study of paired associate learning shows that a first-degree family history of dementia is associated with lowered performance, an effect modified by apolipoprotein E genotype and diabetes.
A novel metabolic network analysis method enables large-scale computational predictions of biosynthetic capabilities across the human oral microbiome, revealing a unique cluster of fastidious microorganisms and potential metabolic interdependencies.
Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.
Analysis of the atypical tryptophan biosynthetic operon of Chlamydia trachomatis revealed the simultaneous regulation of transcriptional initiation and termination by an iron-dependent repressor, expanding known regulatory mechanisms of this pathway.
