![Most theoretical work on the origin of heredity has focused on how genetic information can be maintained without mutational degradation in the absence of error-proofing systems. -- [PLOS Biology]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Selection-For.png?resize=1200%2C715&ssl=1)
[PLOS Biology] A simple and parsimonious solution assumes the first gene sequences evolved inside dividing protocells, which enables selection for functional sets. But this model of information maintenance does not […]

Aboard The International Space Station, Viruses And Bacteria Show Atypical Interplay
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria […]

Integrating Phylogenies Into Single-cell RNA Sequencing Analysis Allows Comparisons Across Species, Genes, And Cells
Abstract: Comparisons of single-cell RNA sequencing (scRNA-seq) data across species can reveal links between cellular gene expression and the evolution of cell functions, features, and phenotypes. These comparisons evoke evolutionary […]
