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.

A new cell–cell communication system in Streptococcus salivarius, a human gut commensal, discriminates between close signaling molecules to specifically produce bacteriocin-based antimicrobials and disconnects it from foreign DNA acquisition.

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.

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.

The role of an amino acid-dependent tRNA modification as a nutrient sensor and regulator of metabolic homeostasis has been discovered.

Formin-2 controls spatiotemporal polymerisation of actin filaments, a common mechanism used by apicomplexans for effective segregation of essential chloroplast-like organelles called apicoplasts, and additionally for daughter formation in Plasmodium falciparum.

The fungal parasite Podosphaera plantaginis employs both sexual and asexual reproduction to increase its chances of infecting the plant Plantago lanceolata.
