Placing very long branch taxa in the plant tree of life: A case study with Dioscoreales mycoheterotrophs

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

Transitioning to nonpunitive school policies for addressing student substance use: Qualitative interviews with key school administrators

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Recent policy change in Massachusetts encourages schools to limit their use of exclusionary discipline to “extraordinary circumstances,” but little work has explored the opportunities and challenges of transitioning to nonpunitive practices after student substance use infractions in schools.

Initial Stay Time and Work‐Rest Scheduling During Consecutive Heavy‐Intensity Workdays in Hot Environments in Young and Older Males

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction This study examined initial stay times (IST), defined as the duration of uninterrupted work before core temperature approaches recommended safety limits (38.0°C, ~1.0°C above baseline), and the efficacy of work‐rest cycles during repeated heavy work across consecutive workdays in young and older males.

Differential Diagnosis of Mucopolysaccharidoses Types I, II, III, IVA, and VI Through Analysis of Leukocytic Inclusions

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mucopolysaccharidoses (MPS) are lysosomal storage disorders characterized by the accumulation of glycosaminoglycans (GAGs), which can lead to cytoplasmic alterations in leukocytes. The objective of this study was to characterize leukocyte inclusions in patients with different types of MPS and assess their diagnostic relevance.

Expanding the DNA Nanotechnology Toolbox: Hierarchical Assembly and Self‐Sorting of DNA Tiles With Precisely Controlled Hydrophobic Behavior

open access: yesAngewandte Chemie, EarlyView.
DNA tile amphiphiles encode dual chemical information, directing nanostructure formation through base‐pairing and hydrophobic effects. Thermal annealing programs hierarchical assembly, with first‐formed interactions biasing the final morphology: short hydrophobic chain strands form DX‐tiles and then into stars, while long‐chain strands form SNAs and ...

Australian Activists as Storytellers in Digital Spaces: Acquiring Skills, Producing Content and Getting the Message Out

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT As modes of activism rapidly evolve, activists—both seasoned and emerging—must increasingly navigate a hybrid terrain of both digital and non‐digital engagement. This paper draws on the personal narratives of 16 nascent activists based in Australia to explore how they develop competencies related to digital storytelling, which is critical to ...

Extending Small‐Molecule Aptamer Discovery Principles to Protein Targets: Selection and Characterization of Green Fluorescent Protein Aptamers

open access: yesAngewandte Chemie, EarlyView.
Protein‐binding aptamers remain poorly understood compared to their small‐molecule counterparts. Using green fluorescent protein (GFP) variants as a tractable model system, we show how subtle changes in protein surface composition and divalent metal ions reshape aptamer selection, specificity, and binding.

Mechanical Thrombectomy Versus Medical Management for Large Ischemic Core Stroke Identified before Inter‐Hospital Transfer: A Post Hoc Analysis of the LASTE Trial

open access: yesAnnals of Neurology, EarlyView.
Objective This study assessed the efficacy of thrombectomy in acute ischemic stroke because of large‐vessel occlusion (AIS‐LVO) initially admitted to primary stroke centers (PSC) and subsequently transferred to a comprehensive stroke center (CSC), with a large ischemic core identified before transfer.

Anion–π Interaction‐Regulated Ion Generation and High Piezoionic Response in Ultrasoft Low‐Salinity Hydrogels

open access: yesAngewandte Chemie, EarlyView.
The first hydrogel system employing anion–π interactions as a central design motif is developed. The cooperative aromatic–phosphate interaction motif provides dynamic cohesion and is proposed to regulate the separation and transport of water‐derived ionic species, achieving high piezoionic response in injectable, self‐healing, ultrasoft, low‐salinity ...

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

open access: yesAngewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...
