Diverse histories of viral exposure, for example in individuals of different age, makes viral evolution less predictable with features of adaptive and neutral evolution.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.
Mutagenizing sequences enriched with promoter motifs creates gene expression de novo, and helps to understand promoter logic, regulatory evolution, and the birth of de novo genes.
Aphid and mildew read counts leftover from the sequencing of greenhouse plants correlated with the environment of origin of the plants, and allowed the mapping of pathogen resistance genes.

Iron-chelating pyoverdines from environmental Pseudomonas spp. show promising antibacterial activity against key human pathogens through the induction of iron starvation, while associated toxicity for host systems remains low.

Laser-stimulated fluorescence (LSF) imaging of early pterosaurs uncovers new soft tissue data of tail vane that reveals sophisticated, dynamic tensioning usage and expands its evolutionary origins.
Analyses of discovered cancer-driving nucleotides (CDNs) reveal their evolutionary, biochemical, and therapeutic characteristics that are often shared among multiple cancer types.
A mathematical model shows that mutations that recur even modestly among cancer patients are cancer driving nucleotides that can be exhaustively identified to serve as targets of cancer therapy.
