Selective sweepstakes from pervasive positive selection, rather than demographic changes or random sweepstakes reproduction, is the primary determinant of reproductive skew and genetic diversity in the highly prolific Atlantic cod.

Tissue-specific Cre recombinase often drives 'off-target' reporter activity in the male reproductive tract, suggesting the potential for inter-tissue RNA or protein trafficking in control of sperm maturation or other aspects of reproductive physiology.
Combining ribosome profiling and RNA sequencing illuminates novel features of porcine reproductive and respiratory syndrome virus gene expression, including the regulation of polyprotein stoichiometry through temporal modulation of ribosomal frameshifting and the synthesis of non-canonical transcripts.
Interventions in feedlots and abattoirs place selective pressure on the beef cattle resistome, which differentially impacts the public health risk of antimicrobial resistance from beef production sources.
Discovery of a novel mode of sexual reproduction, termed pseudosexual reproduction, in fungi where both parents are required for mating but only one contributes to the meiotic progeny, similar to hybridogenesis in animals.
