Ontologies for Sustainability: Theoretical Challenges

open access: yesSustainable Development, EarlyView.
ABSTRACT The lack of sustainable practices in key sectors of human societies is a global concern, posing threats for the whole planet. This paper provides the first review of ontologies for sustainability efforts, outlining their roles in assessing and advancing such efforts. Section 2 outlines three major challenges associated with sustainability: (1)

Single‐Particle Characterization Reveals Heterogeneous Extracellular Vesicle Fusion with Liposomes

open access: yesSmall Methods, EarlyView.
This study used five orthogonal single‐particle techniques to compare how common mechanical methods fuse extracellular vesicles with liposomes. By quantifying fused‐particle yield, purity, and vesicle integrity, we found that freeze‐thaw and sonication generated the highest fusion but that all methods introduced membrane perturbation or damage.

A novel circumscription and classification for Neurolaeneae (Asteraceae)

open access: yesTAXON, EarlyView.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...
