Cryo electron microscopy and structure-based mutagenesis reveal that the bacteriophage BPP-1 contains two of the three major recognized viral folds, one of which exhibits a new topology.

The midbrain periaqueductal grey is a conserved mediator of elaborate courtship behavior in a range of vertebrate taxa, likely shaping how this behavior diversifies across the tree of life.

Variation in patterns of floral UV pigmentation is controlled by a single transcription factor in sunflower and affects both pollinator attraction and responses to environmental stresses.

Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.

An analysis of the genomic features that distinguish conserved from species-specific circular RNAs reveals that the expansion of the downstream intron by insertion of retrotransposons stabilizes circular RNAs' production across 30+ millions years of evolution.

Synthetic single domain antibody libraries and a binder selection cascade encompassing ribosome and phage display enable the selection of conformation-specific binders against previously intractable membrane proteins within three weeks.

Tronko provides a scalable solution for accurate taxonomic assignment for large-scale metabarcoding datasets by overcoming the speed and memory limitations of previous phylogenetic placement methods.

CR9114, one of the most broadly neutralizing anti-influenza antibodies characterized to date, acquires affinity to divergent HA subtypes sequentially, due to higher order interactions between the nested sets of mutations required for binding each distinct subtype.

Characterisation of within-host diversity of SARS-CoV-2 provides insights into the mutational and selective mechanisms driving its evolution and has important implications for using within-host variation to inform transmission inference efforts.

Multimodal signals may evolve from unimodal one via co-option of primary signal components and associated cues that serve as by-products.
