Single viral mutations can escape polyclonal human immunity to influenza hemagglutinin, but different mutations escape the immunity of different people.

Drug-resistance declines in the laboratory in an antibiotic stress-free environment, indicating that restricting antimicrobial usage in the clinics could be a useful policy.

Transporters shared by fungal intracellular parasites provide new insights into the evolution of nucleotide and energy parasitism.

Nematode hermaphroditism has co-evolved with a self-sperm sensing mechanism that protects hermaphrodites from the detrimental effects of mating with males.

Single-cell RNA-sequencing and germline substitutions provide novel insights into how testis is a hotspot for evolutionary innovation of genes, expression, and mutation at the single-cell level.

Young Caenorhabditis elegans hermaphrodites use their own sperm to protect against the negative consequences of mating.

Synonymous mutations can have highly variable fitness effects stemming from changes in transcription, some of which contribute to adaptation.

Tight regulation of a central developmental kinase cascade evolved through two key mutations.

Applying ancestral sequence reconstruction techniques to protein kinases reveals the mutations that underlie different modes of activation.

When landing, Pacific parrotlets exhibit stereotyped leg and wing dynamics regardless of perch diameter and texture, but foot and claw kinematics become surface-specific upon touchdown to successfully grasp the perch.
