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.

Rat blood profiles support non-linear aging with distinct trajectory shifts, and these profiles could be used to predict non-overt illness in rats or aging intervention efficacy.

The first nuclear genomes of the Equus (Sussemionus) ovodovi enable us to reconstruct the speciation and extinction trajectory of this lineage.

Hybridization not only generates genetic diversity, but this diversity can alter the shape of the fitness landscape, changing which genotypic combinations are favored by natural selection and which accessible genotypic paths lead to novel fitness peaks.

African haplotypes of a meiotic drive supergene in Drosophila melanogaster called Segregation Distorter show signs of a recent selective sweep, reduced recombination, and increased genetic load.

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

Orthologous proteins display different mutational robustness that can be leveraged to improve prediction of functional sequences.

The HIV proteins Env and Rev encode helices that overlap in the viral genome but alternate in functional importance so that the non-functional surface of one helix encodes the functional surface of the other.

Using a neural network to predict how green fluorescent proteins respond to genetic mutations illuminates properties that could help design new proteins.

Leveraging the US Health and Retirement Study and C. elegans genetics reveals ALDH4A1/alh-6 as an evolutionarily conserved biomarker for normal muscle function over the lifespan.
