Children’s health before, during, and after parental/caregiver immigration detention in the United States: findings from a cross-sectional survey

Background Parental immigration detention is a significant yet understudied stressor with potential consequences for children's well-being. We examined children's general health before, during, and after parental detention, and compared to the United States (US) pediatric populat...

Evolution towards monomorphy leads to a loss of morph plasticity in wing polymorphic crickets

Threshold traits are widespread forms of dimorphism in which an underlying continuous liability produces discrete phenotypes once a threshold is crossed. The threshold trait model predicts that phenotypic variation will be observed only when the distribution of liability spans th...

pynucastro 3: A community library for nuclear astrophysics

We describe the latest release of pynucastro: a community python library for nuclear astrophysics. The goal of the pynucastro project is to build the tools needed to interactively explore nuclear properties, reaction rates, and networks, and to export these networks to a variety...

Nonlinear interpolation and the flow map of quasilinear equations

We prove an interpolation theorem for nonlinear functionals defined on scales of Banach spaces that generalize Besov spaces. It applies to functionals defined only locally, requiring only some weak Lipschitz conditions, extending those introduced by Lions and Peetre. Our analysis...

Fungal frontiers for sustainability: unlocking the hidden kingdom

Fungi have repeatedly delivered transformative advances across industries, from medicine to food to materials, yet these breakthroughs have emerged from a narrow base of organisms and well-studied systems. Although mycology has taken a big leap forward in the past decades because...

Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability

ABSTRACT Achieving high‐energy‐density and long‐term cycling stability in Mn‐redox‐based cathodes is a critical step toward advancing Ni‐ and Co‐free Li‐ion chemistries to diversify supply chains and lower battery costs. Here, we demonstrate an unusually high performance benchmar...

Dynamic estimation of airport taxiway hotspots using spatio-temporal traffic and kinematic risk modeling

At busy airports, airfield operations are among the most safety-critical phases of flight because aircraft move through complex taxiway and runway-crossing networks. Despite ground-surveillance advances, taxiway conflicts remain a concern. We develop a traffic-based method for dy...

Modeling human neurodegeneration with iPSCs: opportunities, limitations, and the challenge of aging

Most neurodegenerative diseases reflect patient-specific combinations of polygenic risk variants interacting with aging and environmental factors, rather than a single causative mutation. Phase III clinical trial failure rates for neurodegenerative indications exceed 95%, reflect...

Effect of seawater on the reactivity, microstructure, and strength of Roman-inspired lime-pozzolan binders

Roman marine concretes were frequently produced using seawater, yet the influence of seawater on lime-pozzolan reactions remains poorly quantified. In this work, pastes and mortars prepared with slaked lime and a natural pozzolan from the Phlegraean Fields were mixed with either...

Liposome supplementation enhances host metabolism in a model symbiotic cnidarian

Abstract Stable cnidarian–dinoflagellate symbioses provide the trophic foundation of coral reef ecosystems. Understanding nutrient exchange underpinning this symbiosis, and the need for interventions to improve coral health via aquaculture, grow increasingly urgent as reefs face...

Basin-scale organization of groundwater and surface water during the monsoon season: Hydrochemical and isotopic insights from the Brahmaputra River Basin, Northeast India

Study region The Indian sector of the Brahmaputra River Basin (BRB). Study focus We co-evaluated groundwater (GW) and river water (RW) across the Indian BRB using a synoptic monsoon-season survey (July 2022; n = 83; 36 GW, 47 RW). Hydrochemistry, stable isotopes (δ²H, δ¹⁸O), wate...

“The measure of your [thinking] is to me unknown:” Aḥmad Fāris al-Shidyāq’s Comparative Epistemology in “Maqāmah on Chapter Thirteen”

Aḥmad Fāris al-Shidyāq (1804/5–1887) was an unusual Arab renaissance figure whose work spanned travel and fictional writing, Bible criticism and translations, Arabic lexicography, poetry, philology, and grammar. His intellectual and professional life involved working with several...

Association of Caregiver Mental Health and a Childhood Parenting Intervention in China

OBJECTIVES This study examines whether and how caregiver mental health symptoms influence the impacts of a center-based parenting intervention on child development. METHODS We conducted a clustered randomized controlled trial across 100 rural villages in China between 2016 and 20...

THEMIS: spin axis magnetic field reconstruction

Abstract. The Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission investigates the coupling between the solar wind and Earth's magnetosphere using five identical spinning spacecraft. Each spacecraft rotates at a predefined rate to stabilize it and...

Cobamide-based interactions between soil bacteria can be predicted based on monoculture growth

ABSTRACT Interactions between microbes shape the structure and function of microbial communities. While studying interactions is key to understanding microbial communities as a whole, gaining a detailed mechanistic view is challenging due to the number of co-occurring interaction...

Health services intervention integrating HTN and HIV care improves long-term blood pressure control among people living with HIV in Uganda

Background Globally, the prevalence of hypertension (HTN) among people with HIV (PWH) has increased dramatically over the last decade. In a cluster randomized trial, we evaluated the effect of a multicomponent intervention model on blood pressure (BP) control among PWH in rural U...

Caregivers in a Haystack? Informatics‐Driven Clinical Trial Enrollment of Dementia Caregivers at Medical Visits

BACKGROUND: Caregiving status is not routinely documented during clinical care, rendering caregivers difficult to identify for research and supportive interventions. We describe two informatics-based strategies for identifying dementia caregivers at their own or their care recipi...

An automated operon refactoring workflow for heterologous expression of non-ribosomal peptide biosynthetic gene clusters

Microbial genomes encode numerous biosynthetic gene clusters, yet most remain experimentally uncharacterized, particularly large non-ribosomal peptide synthetase (NRPS) clusters that resist conventional cloning. Existing refactoring approaches are labor-intensive, depend on de no...

The First Multi-Messenger Nova: External Shocks, TeV Photons, and Neutrinos in the Next Eruption of T CrB

Abstract T Coronae Borealis is the most compelling anticipated Galactic recurrent nova and one of the best opportunities to test whether nova eruptions can become genuine multi-messenger transients. Recent observational work on classical novae has shown that the GeV γ-ray luminos...

Worth Their Weight: Randomized and Regularized Block Kaczmarz Algorithms without Preprocessing

Abstract. Due to the ever growing amounts of data leveraged for machine learning and scientific computing, it is increasingly important to develop algorithms that sample only a small portion of the data at a time. In the case of linear least-squares, the randomized block Kaczmarz...
