Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.

Methylglyoxal Affects Dopamine Homeostasis in SH‐SY5Y Cells Through the Modulation of miR‐190a and miR‐214

open access: yesThe FASEB Journal, Volume 40, Issue 5, 15 March 2026.
In SH‐SY5Y cells, Methylglyoxal (MGO) reduces the intracellular dopamine content, up‐regulating the expression of proteins that modulate dopamine amount (MAO‐B, COMT, and α‐Syn). The MGO‐induced increase of COMT and α‐Syn expression is mediated by the reduction of miR‐214 and miR‐190a levels.

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 3, Page 694-718, March 2026.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.
