Comprehensive Analysis of US Health Care Spending on Injuries
BACKGROUND: Traumatic injury affects every age group, payer, and care setting in the United States, yet how injury-related spending distributes across these dimensions has not been comprehensively quantified. OBJECTIVE: To estimate US health care spending on injuries in 2022 by m...

Neural mechanisms of sensory over-responsivity in youth with early caregiver-related adversity
Abstract Sensory over-responsivity (SOR) is an impairing sensory processing challenge prevalent across a range of clinical and neurodevelopmental populations, as well as those with experiences of early caregiver-related adversity. Despite its prevalence and impairing nature, litt...

An Injury-Conforming Dual-Layer Lung Sealant
Abstract Persistent pulmonary air leaks contribute to prolonged hospitalization. While existing hydrogel-based sealants can be used to stop air leaks, they may lack the high elasticity needed to accommodate lung deformation and mechanical cohesion. We developed an injury-conformi...

Glacier surges on James Ross Island, Antarctica, and their relationship with climate
Abstract. Although the Antarctic Peninsula has a similar climate to that of other regions hosting surge-type glaciers, only one glacier surge has been previously observed in this region. We examined ice surface velocity, elevation and terminus position changes of Antarctic Penins...

Presenceof CriticalMaterials in Select U.S. MunicipalSolid Waste Landfill Leachates
Abstract This study detected and quantified a broad array of critical materials and other elements in U.S. municipal solid waste (MSW) landfill leachates in both the aqueous (i.e., supernatant) and wet solid fractions. A total of 59 elements were measured in 37 landfill leachate...

A compendium of next-generation patient-derived models for diverse cancers
Abstract The development of new therapeutics and the validation of pathogenetic cancer mechanisms require representative laboratory models 1,2 . However, existing collections represent only a fraction of the diversity observed in human cancer 2–4 . Recent technologies have enable...

From Gene Editing to Exogenesis: Pigs as a Source of Immune-compatible Organs for Transplantation
The persistent shortage of human organs for transplantation has intensified efforts to develop alternative sources, specifically xenotransplantation and exogenesis. Xenotransplantation uses genetically engineered pigs to provide organs, tissues, and cells for clinical use. Signif...

The expression of metazoan replication-dependent histone genes is controlled by NPAT and U7 snRNP. NPAT activates transcription of histone genes during S-phase, whereas U7 snRNP is a multi-subunit endonuclease that cleaves the resultant transcripts at the 3' end, yielding mature...

Access to Anticancer Drug Trials for Adolescents With Cancer in the United States
BACKGROUND: Adolescents with cancer are generally underrepresented in clinical trials. The extent to which cancer drug clinical trials have become more age inclusive over time is not clear. METHODS: We utilized ClinicalTrials.gov to identify cancer drug trials from 2005 to 2025 i...

What Does It Mean to Be Black? Experimental Evidence on the Situational Deployment of Racial Schemas
How do Black Americans construct narratives about the meaning and boundaries of Blackness in America today? We leverage an original, nationally representative survey experiment among U.S.-born Black Americans ( n = 3,100) to examine (1) justifications used to validate or reject a...

Exposure to air pollutants in indoor and outdoor school environments poses significant health risks to children due to their heightened vulnerability. Increasing wildfire frequency has intensified transboundary smoke transport, with border communities among the first to experienc...
- Materials & Energy
Carbon nanotubes (CNTs) are important materials for electronics and structural composites, but their production still relies on hydrocarbon-based chemical vapor deposition, an energy-intensive and fossil-dependent process, limited by rapid catalyst deactivation. Using CO 2 as a c...
