Delineating Episyrphus balteatus transregional movements and pollination networks advance a deep understanding of its migration ecology and facilitate the design of targeted strategies to conserve and enhance its ecosystem services.
New digital restorations indicate that the structure and function of the shoulder joint were highly variable among Early Cretaceous birds, with such key features as the configuration of the triosseal canal and the nature of scapula-coracoid articulation showing considerable diversity.

Acetylation of nuclear basket components, following their interaction with accumulating extrachromosomal DNA circles, drives the reorganization of nuclear pore complexes and the loss of cellular viability associated with replicative ageing.

Wings achieve plasticity in size while maintaining robust pattern via ecdysone, which elicits graded responses for growth rates and threshold responses for patterning rates, in the fruit fly Drosophila melanogaster.
The fate of duplicated transcription factors within budding yeast is described, providing insights into the mechanisms that shape transcriptional networks during evolution.

Lifelong continuous reproduction, late-life investment into female sexuals, a short phase of senescence, and reproductive death characterize the life history of Cardiocondyla obscurior ant queens.
The fossil record of abdominal modifications in male scorpionflies documents a relatively late evolution of oppressive behaviour toward a female during mating and suggest degree of sexual coercion greater in Eocene than in any other known scorpionfly, extinct or extant.

A bulk barcoded quantitative trait locus approach increases the power and resolution of genotype-phenotype mapping in yeast, revealing that the genetic architecture of 18 complex traits is highly polygenic, and is characterized by widespread epistatic interactions and pleiotropic effects.

Phylogenomics of sea urchins clarifies their origins and diversification history, reveals surprising discrepancies with their rich fossil record, and serves as basis to explore the sensitivity of time calibration analysis.
