The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

Increasing nitrogen loading in the Gulf of Mexico undermines coral reef resilience

The ongoing global decline of coral reefs underscores the need to identify key mechanisms driving reef deterioration. The Flower Garden Banks (FGB) reefs in the northern Gulf are widely regarded as some of the healthiest in the continental United States, but recent disease outbre...

Ancient DNA preservation in the Caribbean

Abstract Ancient DNA (aDNA) analysis has transformed how we study human migration, species dispersals and environmental change, but poor preservation remains a major challenge. This is especially true in tropical settings, where hot and humid conditions accelerate DNA decay. Beca...

Research on multimodal dense small object detection algorithms guided by cross-modal information

To address the challenges of modality heterogeneity, scale inconsistency, and background interference in dense small object detection under multimodal conditions, this paper proposes a novel detection framework based on cross-modality guidance and hierarchical scale refinement. B...

The MAHA Physical Activity and Fitness Strategies Are Inconsistent With and Ignore Priorities Established by Good Science and Pedagogy

This Viewpoint explores the Make America Healthy Again Commission’s framework for early childhood and out-of-school programs for increasing physical activity and improving nutrition options among US youths.

Divergent biological consequences of APOE isoforms across industrialized and non-industrial environments

Abstract The apolipoprotein ε4 (APOE ε4) isoform directly alters cholesterol and immune biology and is associated with an increased risk of neurodegenerative and cardiometabolic disease in industrialized settings; nevertheless, APOE ε4—which is ancestral in humans—has persisted o...

Small mammalian herbivores at moderate densities facilitate livestock growth by improving vegetation composition in grasslands

Small mammals and large herbivores have co-evolved in grasslands for millions of years, yet how they interplay remains unclear. Although large herbivores can significantly affect the smaller ones, the reversal effect is largely unknown. On the Qinghai–Tibetan Plateau, plateau pik...

Outgroup representation in close networks shows a nonlinear association with mental well-being

Building on research linking social diversity to well-being, we examined how racial outgroup representation in individuals’ close social networks relates to mental well-being during two periods of heightened societal stress: the COVID-19 pandemic and a polarized election period....

How Can Peer Presence Cause Distraction and Error Among Construction Workers? A Virtual Reality Study

Construction workplaces are hazard-rich environments where workers must maintain sustained attention to prevent human errors. In parallel, construction jobsites are inherently social environments that require collaborative work and peer interactions. Such interactions and peer pr...

The distribution of fitness effects of nonsynonymous mutations varies phylogenetically across animals

The distribution of fitness effects (DFE) describes the selection coefficients of newly arising mutations and fundamentally influences population genetic processes. However, the extent and mechanisms of differences in the DFE for non-synonymous mutations have not been systematica...

Tuning the Magnetic Properties of Kitaev Materials via the Antiferromagnetic Proximity Effect: Novel Phases and Application to an α -RuCl3/MnPS3 Bilayer

Abstract In recent years, the increasing level of control over van der Waals (vdW) heterostructures has opened new routes to tune the properties of quantum materials. Motivated by these developments, we examine the potential consequences of interfacing a Kitaev honeycomb magnet,...

Gastronomy as an engaging form of creative tourism enhanced by co-creation and nostalgia

Gastronomic encounters increasingly function as creative tourism experiences in which participation and nostalgia shape how tourists feel, think, and act toward a destination. This study examines the role of creative tourist experiences, gastro-nostalgia, and co-creation intentio...

Energy Expenditure During Walking in Adults: Impact of Body Mass Index and Sex

Purpose: The aim of this study was to determine if the linear and nonlinear coefficients of the energy expenditure-walking speed relationship are influenced by body mass index (BMI; kg/m 2 ) and sex. Methods: Participants (n=182; 96 females) ages 18-60 yr walked at 0.89 m/s (2.0...

A firefly-inspired model for detecting the alien

The Search for Extraterrestrial Intelligence (SETI) has historically been a search for aliens like us, shaped by human-centric ideas of intelligence, communication, and technology. However, humans are not the only instance of an intelligent, communicating species on Earth, and th...

“WIC helps, but there are challenges”: A thematic analysis of Latina immigrant mothers’ experiences with Missouri’s WIC program

This qualitative study explored Latina immigrant mothers’ experiences with the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Missouri. Twelve focus groups were conducted via Zoom (2021–2023) with 32 Latina immigrant mothers residing in Missouri....

Nationwide Assessment of De Facto Wastewater Reuse Reveals Vulnerable Drinking Water Systems and Infrastructure Gaps

Abstract Unplanned wastewater reuse, or de facto reuse (DFR), improves surface water supply resiliency but can introduce nutrients and emerging contaminants into drinking water sources. Previous national DFR assessments excluded thousands of smaller drinking water systems that se...

Design for Human Variability: Reflections from the HFES Council of Affinity Groups (COAG)

The Human Factors and Ergonomics Society (HFES) is dedicated to recognizing human variability and understanding how it shapes interactions between people and systems. Building on previous panels, this discussion panel examines human variability through the lens of HFES Affinity G...

Evaluating classification approaches for population affinity estimation in a contemporary South African CT-derived sample: an automatic landmarking-based approach

Population affinity estimation remains an important component of the biological profile, particularly in demographically complex populations such as South Africa, where morphological overlap exists among groups. This study evaluated the performance of geometric morphometric (GMM)...

Archival half-life: witnessing Sikh bodily decay in the postcolonial archive

This response discusses the project of documenting Sikh women’s stories and their utility in seeking closure. Closure is articulated by many in The Kaurs of 1984 as an impossible goalpost in the aftermath of 1984, particularly as these Sikh women grapple with bureaucratic injusti...

Vertebral Body Wedge Geometry Predicts Lumbar Lordosis Beyond Pelvic Morphology in Chronic Low Back Pain

Objectives: Lumbar vertebral wedge angles reflect vertebral body geometry and may influence lordosis. Whether the total wedge index (TWI) and segmental wedge angles differ between asymptomatic individuals and chronic low back pain (CLBP) patients, and predict lordosis independent...
