Cell surface architecture of the cultivated DPANN archaeon Nanobdella aerobiophila

This study characterizes the cell surface structures and symbiotic interactions of the DPANN archaeon Nanobdella aerobiophila using electron microscopy, transcriptomics, and genomics.

Eusocial evolution without a nest: kin structure of social aphids forming open colonies on bamboo

The paper compares kin structure and genetic relatedness in eusocial and non-eusocial aphid colonies on bamboo, finding that eusocial colonies are more genetically homogenized, suggesting ecological factors favor eusociality.

Seasonal polyphenism underlies the origin of a sterile caste in aphids

This study shows that seasonal polyphenism in aphids was repurposed to evolve a sterile soldier caste, with shared developmental mechanisms and fitness benefits.

Rapid Speciation Characterized by Incomplete Lineage Sorting in the Globally Distributed Bacterium Sulfitobacter

The paper identifies incomplete lineage sorting in Sulfitobacter, a marine bacterium, showing rapid speciation driven by ancestral polymorphism retention rather than adaptive selection.

Defensive nymphs in the water-repellent gall of the social aphid Colophina monstrifica (Hemiptera: Aphididae: Eriosomatinae)

The paper describes the induction of galls by the aphid Colophina monstrifica on Zelkova serrata and documents defensive behaviors of nymphs against moth larvae.

Isolation of an archaeon at the prokaryote-eukaryote interface

The paper isolates an Asgard archaeon and proposes a symbiosis model for eukaryogenesis based on its morphology and metabolism.
