Selection for asymmetric signalling between gametes explains the very origins of sexual asymmetry as seen in mating-types with morphologically similar but self-incompatible gametes.
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.
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.
