Predictable patterns of fitness evolution observed in microbial evolution experiments can emerge generically as a consequence of widespread epistatic interactions between mutations.

A first-principles acoustics model reveals how the acoustic spectrum generated by flapping wings originates from oscillating aerodynamic forces, and is validated by in vivo aerodynamic force measurements and acoustic holography.
The sounds of flying animals, such as the hum of a hummingbird as it hovers, are influenced by the unique forces generated by the flapping of their wings.

aDNA revealed a model of domestication where an ancient guanaco population no longer exists, the loss of the ancient vicuña genetic variation in the modern populations, and frequently interbreeding practices.

Integrons deploy a variety of adaptive strategies including excision, shuffling, and duplication of cassettes that foster rapid bacterial adaptation and resistance evolution while protecting the genomic integrity of the host.
Neuropeptide tachykinin signaling acts as master regulator of behavioral specialization in honeybees by differentially modulating worker responsiveness to task-specific stimuli.
In addition to its academic merits, characterizing the genetic determinants of male (in)fertility and identifying clinically actionable genetic variants can lead to improved diagnosis or even treatment of such conditions.
