Host Aging Induces a Senescent‐Like Phenotype in Neutrophils and Altered Transcriptional Responses to Streptococcus pneumoniae

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Aging is associated with a senescent‐like phenotype in neutrophils that emerges in bone marrow cells; however, many facets of this phenotype are only fully acquired upon entry into peripheral tissues. This neutrophil senescent‐like phenotype is in part driven by TNFα and impairs resistance of aged hosts to S. pneumoniae. Created in BioRender. Boughanem

Genetic diversity and molecular phylogeographic analysis of an alien praying mantis, Hierodula chinensis, in Japan

open access: yesEntomological Science, Volume 29, Issue 1, March 2026.
Analysis of the COI gene in 127 individuals of Hierodula chinensis from 40 sites in Japan revealed 18 haplotypes that clustered into two genetically distinct clades. Thirteen haplotypes were each detected in only a single prefecture, whereas five haplotypes were found across multiple prefectures. Abstract Hierodula chinensis Werner (Mantodea: Mantidae),
