Influence of Color-Center Electronegativity on Circular Dichroism in Single-Walled Carbon Nanotubes

Abstract Covalently functionalized single-walled carbon nanotubes (SWCNTs) have emerged as attractive quantum photonic materials due to their highly tunable optical properties and efficient single-photon emission capabilities. Recent progress in engineering chiral defects has mot...

Blue-sky thinking about pronunciation research and teaching

Abstract In the fall of 2024, Ron Thomson and Tracey Derwing invited 15 pronunciation scholars representing several subspecialties to participate in a full-day symposium to discuss directions for pronunciation research. To prepare for the symposium, held in conjunction with the P...

FERONIA phosphorylates the amino-terminal extension of phytochrome B to modulate plant light and temperature responses

FERONIA (FER) receptor kinase is a critical regulator in balancing plant growth and stress responses. As an active kinase, FER phosphorylates many proteins to regulate their stability, nuclear accumulation, and condensation in diverse biological processes. Phytochrome B (phyB) is...

A novel anaerobic cholinergic signaling compound, β-alanine betaine, and nAChRs in Ascaris

Anthelmintic drugs are used to control soil-transmitted helminths that infect a quarter of the world’s human population. There is increasing concern about the development of resistance to anthelmintic drugs because of the limited number of compounds available and there is an unme...

OSI Stack Redesign for Quantum Networks: Requirements, Technologies, Challenges, and Future Directions

Quantum communication is emerging as a foundation for next-generation networks, offering unprecedented capabilities in security, entanglement-based connectivity, and distributed computation. However, the classical Open Systems Interconnection (OSI) model, designed for determinist...

Maternal Tuberculosis and Infant Gut and Immune Development: Implications for Maternal-Child Health

BACKGROUND: Maternal tuberculosis (TB) during pregnancy involves chronic infection, immune activation, and antimicrobial therapy, which may alter the maternal gut, vaginal, and breast milk microbiomes and influence neonatal immune development. METHODS: We conducted a narrative re...

Radon-induced backgrounds in the NEXT-100 experiment

A bstract The NEXT-100 detector at the LSC aims at the first competitive search for the 0 νββ decay using a high-pressure 136 Xe electroluminescent time projection chamber. The first low-background run of NEXT-100 at 3.95 bar has been devoted to the measurement of the radon-induc...

Quality Assessment of Farmer-Managed Tropical Pumpkin (Cucurbita moschata Duch.) Seeds in Uganda

Tropical pumpkin (Cucurbita spp.) is an underutilized, nutrient-dense vegetable crop with potential to enhance food and nutrition security and generate household income among farming communities. In Uganda, farmers primarily obtain pumpkin seed through informal seed systems, incl...

How AI anxiety and confidence shape student engagement in higher education

The rapid integration of artificial intelligence (AI) into higher education offers opportunities for personalized learning and academic support but may also evoke anxiety, technostress, uncertainty, and concerns about competence, integrity, and future professional roles. This nar...

Oral fluids for detection and characterization of Salmonella in commercial finisher pigs

Salmonella remains an important pathogen in swine production due to its impact on animal health and its role in foodborne illnesses. However, routine surveillance in pigs relies largely on fecal sampling, which can be labor-intensive and difficult to scale across large production...

Core-Regenerating Atom-Pair Exchange Enables Skeletal Carbon Isotope Incorporation into Pyridines

Abstract We report a core-regenerating atom pair exchange strategy for skeletal carbon isotope incorporation into pyridines. The two-step sequence proceeds through pyridine dearomatization followed by a [4 + 2]/retro-[4 + 2] cycloaddition cascade with an isotope-labeled sulfonyl...

Reproducibility, Replicability, and Research Quality in Homogeneous Catalysis

Abstract Researchers from all sectors of homogeneous catalysis convened in response to concerns regarding reproducibility in science to analyze the issue and provide recommendations. In addition to an in-person workshop, the group engaged the broader homogeneous catalysis communi...

Temporal transcriptomic and microbiome changes in American bison during experimental SARS-CoV-2 challenge

Abstract SARS-CoV-2 continues to pose a threat to humans as well as domestic and wild animals. The variability in severity of clinical signs, the zoonotic potential, and the host-specific response to infection contribute to the persistence of circulation of disease. In wildlife s...

Porcine epidemic diarrhea virus infection promotes Peyer’s patch immune induction and epithelial defense via single-cell transcriptional reprogramming

ABSTRACT Porcine epidemic diarrhea virus (PEDV) is an enteric coronavirus causing gastrointestinal disease in swine. To mitigate PEDV risks to swine health, agricultural economic losses, and global food security, a better understanding of host-pathogen interactions is required. U...

Toward a Theory of Digital Platform Frontlines: Understanding the Boundary-Spanning Roles of Influencers in Platform Ecosystems

On digital platforms such as YouTube, TikTok, Twitch, and X, customer engagement occurs not only through traditional employees and self-service systems, but also through influencers. Influencers, particularly those with significant reach, play boundary-spanning roles when they fa...

Side‐by‐side long‐term performance assessment of GFRP ‐ and steel‐reinforced concrete bridge decks

Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing atten...

Evaluating the Effectiveness of a Practitioner-Designed Science-Based Interviewing and Interrogation Course : A Collaborative Training and Research Effort

Purpose Shifting interrogation approaches in the United States from accusatorial practices to science-based methods has been a challenge. The High-Value Detainee Interrogation Group (HIG) research programme has taken a translational approach to evaluating the efficacy and effecti...

Impact of ruminant digestion on germination of native warm‐season grasses in the southeastern United States

Abstract Many forage grasses increase seed dispersal by having their seeds ingested by grazing animals and later deposited elsewhere, reducing parent‐plant offspring competition and improving germination conditions. This study discusses the dissemination of seeds by livestock to...

Edible pedagogies: Designing with food, memory and emotion in the Bagel Studio

This article explores how food-making can support emotional, sensory and reflective learning in design education. Using a 15-week undergraduate and graduate industrial design studio as a case study, the project engaged 23 students in baking bagels to examine intersections of food...

Turns and downturns in aging drivers

As cognitive decline progresses, older adults may self-regulate their driving. Avoidance of left turns across traffic is observable in naturalistic driving data but rarely self-reported. We studied 106 older adults using baseline and one-year follow-up neuropsychological assessme...
