High-level transposon insertional mutagenesis and a broader spectrum of resistance-conferring mutations for selected carbapenems facilitate the evolution of carbapenem resistance in Klebsiella pneumonia clinical isolates.
The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

The transcription networks controlling biofilm formation in Candida species exhibit 'structural' similarities, but show gradual substitutions of transcription regulators and frequent changes in target genes.

The maintenance DNA methyltransferase DNMT1 is required for the transition of spermatogonia to spermatocytes both during larval testis development and adult sperm replenishment in the insect Oncopeltus fasciatus.
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.
