The body plan of the 407-million-year-old plant fossil Asteroxylon mackiei comprised three developmentally distinct systems of axes.

Outbreaks of SARS-CoV-2 transmission in a hospital environment show evidence of superspreading, with 80% of infections caused by 21% of infected individuals.

Neurogenic progenitor cells surrounding the eye placode generate neurons that migrate over long distances to the developing octopus brain.

The longer duration of seasonal influenza virus infection in young children may provide opportunities for within-host evolution as a result of maintenance of genetic diversity through mutation-selection balance.

Beliefs of others’ pain provide a cognitive basis of human empathy and altruism by modulating empathic brain activity.

Allele differences in gene expression dynamics are associated with insertions and deletions and are caused in part by multiple variants within the same promoter region.

With standardized insecticide-resistance assays failing to inform mosquito-control efficacy due to genotype-by-environment effects, practical resistance monitoring under relevant local conditions is needed to correlate resistance, mosquito-control efficacy, and disease epidemiology.

Selective transfer of mitochondria in the Balbiani body ensures high-quality oocyte mitochondria at extreme ploidy, explaining many enigmatic features of female germline architecture including germ cell loss.

One hundred one high-quality drosophilid genomes are released, along with low-cost assembly workflows, as an open community resource for studying genetics, ecology, and evolution in this important model system.

A synthesis of recent hybridization literature reveals emerging patterns in the evolution of genomes after hybridization, processes proposed to explain those patterns, and important open questions to direct future hybrid genomics research.
