High microsatellite but no mitochondrial DNA variation in an invasive Japanese mainland population of the parasitoid wasp Melittobia sosui

The paper investigates genetic variation in Melittobia sosui populations, finding no mitochondrial DNA variation in the invasive mainland population but similar microsatellite variation between native and invasive areas.

Naive and in vitro-activated primary mouse CD8+ T cells retain in vivo immune responsiveness after electroporation-based CRISPR/Cas9 genetic engineering

This study shows that nucleofection-based CRISPR/Cas9 editing preserves in vivo immune function of naive CD8+ T cells but slightly impairs in vitro-activated cells, with varying gene product decay rates.

Multi-tier mechanics control stromal adaptations in swelling lymph nodes

The paper investigates how lymph nodes accommodate size increases during immune challenges by analyzing biomechanical adaptations of fibroblastic reticular cells and fibroblasts.

Solving the sex ratio scandal in Melittobia wasps

The paper resolves the sex ratio discrepancy in Melittobia wasps by showing that females adjust their sex ratio based on dispersal status and relatedness in natural settings, contrasting with laboratory experiments.

CD8+ T cell priming in oral mucosa-draining lymph nodes supports systemic immunity

This study shows that CD8+ T cells are primed in mandibular lymph nodes after oral Listeria monocytogenes infection, contributing to systemic immunity.

Evolution of nuptial gifts and its coevolutionary dynamics with "masculine" female traits for multiple mating

The paper models coevolutionary dynamics between nuptial gift size and female multiple mating propensity, showing that positive paternity gain from large gifts drives female competition and polyandry.

Cooperative interactions among females and even more extraordinary sex ratios

The paper investigates how cooperative interactions among females can lead to more extreme female-biased sex ratios than predicted by Hamilton's local mate competition theory, using wasp species as a case study.

Persistence of a Wolbachia-driven sex ratio bias in an island population of Eurema butterflies

The paper shows that a Wolbachia strain causing female-biased sex ratios persists in an Eurema mandarina population for over 12 years, with stable coexistence of infected and uninfected females.

Seasonal occurrence of diamondback moths Plutella xylostella and their parasitoid wasps Cotesia vestalis in greenhouses and their surrounding areas

The paper tracks seasonal occurrences of diamondback moths and their parasitoid wasps in greenhouses and surrounding areas, finding that greenhouse DBM occurrences are not always linked to surrounding populations.
