Urban vegetation provides substantial health benefits in US cities, yet the protection that existing green cover delivers has not been quantified across a broad national sample. We conducted a census-tract-level health impact assessment across the 200 most populated US cities, estimating premature deaths, stroke cases, and dementia cases attributable to current greenness and the additional burden preventable through a 10% greenness increase. Using peak-greenness Normalized Difference Vegetation Index (NDVI) values derived from Sentinel-2 satellite imagery at 10 m resolution, population attributable fractions applied to county- and state-level baseline disease rates, and dose–response functions from published cohort studies and meta-analyses, we estimated that existing urban vegetation is associated with 133,698 fewer premature deaths annually (95% uncertainty interval [UI]: 97,056 to 214,462), 24,721 fewer stroke cases (95% UI: 11,700 to 31,784), and 16,349 fewer dementia cases (95% UI: 10,609 to 22,403). A 10% vegetation increase would be associated with an additional 18,100 fewer deaths, 3,288 fewer strokes, and 2,125 fewer dementia cases. Per-capita benefits vary 14-fold across cities, driven principally by vegetation level. Equity analysis using the CDC Social Vulnerability Index across 28,620 census tracts shows that the most socially vulnerable neighborhoods have 18% lower vegetation and receive 20% fewer mortality benefits per 100,000 adults than the least vulnerable. These estimates represent the statistical burden attributable to current vegetation exposure rather than individually identifiable prevented events, and they quantify what is at risk when existing urban green space is removed. We identify 4,185 doubly burdened tracts as priority targets for equitable greening investment.
This review synthesizes the key scientific discussions and clinical insights presented at the Core Conference of GlomCon Hawaii 2025, held in Oahu, Hawaii, from September 23–25, 2025.
This article is a review of the public service announcements (PSAs) disseminated with the G.I. JOE: A Real American Hero cartoon series which aired 95 episodes in the 1980s: 35 PSAs were identified and tabulated. The topics addressed ranged from specific health situations to moral guidance. Most of the PSAs (N = 25, 71.4%) were relevant to childhood safety and reflected the theoretical underpinnings of educational messaging likely to promote the most significant change in children's health and health communication targeted to children. The G.I. JOE series can serve as an exemplar for the development of contemporary PSAs intended to improve children's health.
We report a robust Pd-Bi nanoalloy integrated with distorted polyhedral ZnO derived from ZIF-8 for efficient photocatalytic reduction of CO2 to methanol. The hybrid catalyst, denoted Pd x Bi1-x /ZnO (PBZ), delivers a promising methanol yield of 1984 mu mol g-1 with an AQY of 0.87% under 4 h of simulated solar irradiation using water as the electron donor, nearly twice that of pristine ZIF-8-derived ZnO. HR-TEM and HAADF-STEM confirm uniformly dispersed monoclinic Pd-Bi nanoalloys with controlled size evolution governed by the reduction potential disparity of the Pd and Bi precursors. PL and EPR analyses reveal that alloy incorporation suppresses electron-hole recombination and modulates ZnO surface defect states. XPS further validates strong interfacial electronic coupling among Pd, Bi, and Zn, leading to charge redistribution, low-valence Bi species, and metallic Pd. Transient photocurrent and EIS measurements of Pd0.6Bi0.4/ZnO show significantly enhanced charge separation and reduced interfacial resistance, consistent with prolonged charge carrier lifetimes from TCSPC. DFT calculations demonstrate that Pd0.6Bi0.4 nanoalloys exhibit strong CO2 adsorption and effectively stabilize oxygenated intermediates, enabling a thermodynamically favorable pathway toward methanol. The catalyst maintains excellent stability across multiple cycles. This work establishes an effective strategy for engineering defect-rich alloy oxide heterostructures for solar-driven conversion of CO2 to fuel.
Human–computer interaction (HCI) continues to privilege human-centered paradigms even as interactive life unfolds under posthuman conditions, producing a latent ontological misalignment. Consumer-grade sleep-tracking technologies (CSTs) make this ontological tension especially visible: sleep is embodied yet exceeds self-aware experience, rendering it an instructive limit case for phenomenologically informed HCI research. To explore this tension, we systematically identified and analyzed a corpus of 120 peer-reviewed CST publications (2014–2024) across interdisciplinary venues, treating HCI sleep-tracking research itself as an empirical site. Through a critical interpretive synthesis, we analyze how sleepers are enacted through datafication, infrastructural coupling, and algorithmic interpretation. Our findings show that CST research materializes multiple posthuman figures cyborgian, nomadic, and agential realist even as HCI discourse continues to presume a coherent phenomenological subject. This posthuman multiplicity exposes a tension within HCI’s predominant phenomenological inheritance and necessitates engagement with a broader deconstructive lineage. Building on this analysis, we introduce a posthuman design constellation, an ethico onto epistemological tool for conceptualizing how multiple posthuman enactments co-exist within a single sociotechnical arrangement and challenge the presumptive singularity of the phenomenological subject.
