Coexistence of Multiple Endocrine Neoplasia Type 2B and Centri‐Acinar Emphysema With Alpha‐1 Antitrypsin Deficiency: A Case Report

open access: yesRespirology Case Reports, Volume 14, Issue 7, July 2026.
We report on a 32‐year‐old female patient with a very rare coexistence of alpha‐1 antitrypsin deficiency (AATD) and multiple endocrine neoplasia type 2B (MEN2B). Both conditions can affect breathing and may hide each other's symptoms, leading to delayed diagnosis.

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

open access: yesOikos, Volume 2026, Issue 6, June 2026.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.
