Ultrastructural, metabolic and genetic determinants of the acquisition of macrolide resistance by Streptococcus pneumoniae

This study identifies molecular and metabolic factors that influence the acquisition of macrolide resistance in Streptococcus pneumoniae through chromosomal and ICE integration.

Gut microbiota influences foraging onset without affecting division of labor and associated physiological hallmarks in honeybees

This study shows that gut microbiota in honeybees affects the onset of foraging but not division of labor or associated physiological traits.

Opportunity nest egg: insights on the nutritional ecology, life history and captive management of three species of kiwi (Apteryx spp.) chick from Operation Nest Egg zoo hand-rearing records.

This paper analyzes zoo hand-rearing records of kiwi chicks to compare growth efficiency and developmental responses to different diets, finding genetic differences in nutritional needs and suggesting tailored diets for captive management.

Trophic eggs affect caste determination in the ant Pogonomyrmex rugosus

The paper shows that trophic eggs influence caste determination in Pogonomyrmex rugosus ants by affecting larval development into workers or queens.

Natural alleles at the Doa locus underpin evolutionary changes in Drosophila lifespan and fecundity

The paper validates the role of Doa alleles in Drosophila lifespan and fecundity using transgenic RNAi and genetic association approaches.

The evolution of behavioral cues and signaling in displaced communication

This paper shows displaced communication evolves from behavioral cues rather than signal amplitude, as the latter is slower to develop in experimental agents.

Antimicrobial wound care in an ant society

This study shows that ants use antimicrobial compounds from their metapleural gland to treat infected wounds, reducing mortality by 90%.

Invasion genetics of the longhorn crazy ant: the global expansion of a double-clonal reproduction system

This study investigates the reproductive system and genetic diversity of the invasive longhorn crazy ant, finding widespread double-clonal reproduction and a native origin in the Indian subcontinent.

The gut microbiota affects the social network of honeybees

This study shows that gut microbiota manipulation in honeybees increases social interaction rates and specialization, linked to brain metabolite and transcriptional changes.

A single nucleotide variant in the PPARgamma-homolog Eip75B affects fecundity in Drosophila

The paper identifies a SNP in Eip75B affecting fecundity and egg-to-adult viability in Drosophila, but not longevity.

Pdap1 protects mature B lymphocytes from stress-induced cell death and promotes antibody gene diversification

This study identifies Pdap1 as a regulator of mature B cell survival and antibody gene diversification by modulating the integrated stress response and AID expression.

Individuals' expected genetic contributions to future generations, reproductive value, and short-term metrics of fitness in free-living song sparrows (Melospiza melodia)

The paper quantifies individual reproductive value in song sparrows using pedigree data, showing it stabilizes within 20 years and varies more than short-term fitness metrics.

Molecular evolution of juvenile hormone esterase-like proteins in a socially exchanged fluid

The paper investigates the evolution of JH esterase-like proteins in ants, showing their role in regulating larval development through trophallaxis.

Low Rate of Somatic Mutations in a Long-Lived Oak Tree

The paper sequenced two branches of a 234-year-old oak tree and found few somatic mutations, suggesting shoot meristems are mutation-resistant.
