Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.

Mouse models reveal fundamental roles of SMAD1/5 in mediating both bone morphogenetic protein signaling pathways and the transcriptional response to progesterone during decidualization.

Integrated phylogenomics and mitochondrial DNA inventory of net-winged beetles across three continents suggest ~1000 undescribed species, biodiversity hot spots, and phylogeny-based classification that sets up the basis for further research.

Airborne PM2.5 exposure triggers oxidative stress and mitochondrial apoptosis in placental trophoblast cells via the KLF9/CYP1A1 transcriptional axis, ultimately leading to adverse pregnancy outcomes.
