An examination of the use of the UNESCO biosphere reserve designation as a framework for sustainable management and promotion

Purpose The United Nations Educational, Scientific and Cultural Organization (UNESCO) Biosphere Reserve designation has emerged as an influential seal of approval and signal of sustainable management for natural sites. This study examines the extent to which the designation – for...

“I’m never enough”: Associations of childhood emotional abuse subtypes with overweight preoccupation and dietary restraint among women

Childhood emotional abuse from authority figures encompasses verbal abuse, emotional rejection, and overexpectations. Although global emotional abuse is an established correlate of body dissatisfaction and disordered eating, the unique roles of these specific subtypes remain unde...

Prehistoric global migration of vanishing gut microbes with humans

The gut microbiome is crucial for health and is affected strongly by lifestyle1. Many microorganisms commonly found in non-industrialized populations are disappearing or have become extinct in industrialized populations2–6. Studying which microorganisms have been long-term reside...

Quality evaluation of yoghurt incorporated with beetroot puree

Abstract Yoghurt is widely consumed due to its nutritional value and associated health benefits. The incorporation of natural plant-based additives such as beetroot has gained attention as a potential alternative to synthetic ingredients. This study evaluated the effect of beetro...

Coherent virtual absorption in dielectric slabs: a temporal analysis of symmetric and asymmetric geometries

Coherent virtual absorption refers to time-limited storage of optical energy in lossless configurations due to excitation of a complex zero frequency through proper temporal engineering of the incident wave. Given the dynamics underlying the effect and the storage-release mechani...

Evaluating Glanceable Multi-Device Family Health Tracking with Smartwatches and Home Displays

While ubiquitous computing research has explored diverse devices for personal health tracking, we know less about multi-device designs for family informatics, where health management is inherently collaborative. To understand how families adopt and perceive ubiquitous access to s...

II. Chronologies

Abstract Despite a recent shift towards Global South-centred histories of development, women in and from Asia and Africa remain largely neglected in the historiography. In response, this Arenas issue examines the implications of situating the roles and experiences of women at the...

Generalising Aumann's Agreement Theorem

According to Aumann's celebrated theorem, rational agents cannot agree to disagree. In other words, agents who once shared a common prior probability distribution and who have common knowledge about their posteriors cannot assign different probability distributions to a given pro...

Broadening the community of nudibranch enthusiasts through multilingual educational programming to increase climate advocacy engagement

Abstract Environmental literacy and advocacy for environmental protections are essential components of responsible stewardship. For coastal communities, stewardship requires knowledge of ocean processes and the biological communities living within these ecosystems. While many stu...

Do individualists and collectivists cooperate differently?

Do cultural mindsets shape cooperation? Individualists, who view people as independent, and collectivists, who see them as interconnected, make different decisions that impact governance and economic outcomes. This study tests individualism and collectivism (I/C) in indefinitely...

Satellite-based assessment of hydrologic synchronization across Western U.S. basins: Implications for water security

Study Region This study examines the Western United States including five HUC2 watersheds (Upper Colorado, Lower Colorado, Great Basin, California, Pacific Northwest) and 44 HUC4 sub-basins. This region supports over 60 million people and extensive agriculture with water stress f...

Deep learning-based burned area mapping of California wildfires using Sentinel-2 and Landsat-8 imagery enhanced with super-resolution techniques

The increasing frequency of wildfires under a changing climate has led to extensive ecosystem destruction, highlighting the need for reliable burned area assessment using satellite imagery. Single-satellite data are constrained by observation gaps and interference from smoke and...

Centralization vs. Decentralization: First Evidence from the Laboratory

The future architecture of financial systems is a subject of contention, with centralized and decentralized governance proponents. Here, we ask the following question. Would the architecture affect the quality of decision making? We propose a game where financial network particip...

Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets

Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insufficient evidence for a biosphere. In parallel with biosignature detection, exoplanet life detection...

Evaluating large language model performance in US FDA regulatory science

Abstract Background Clinical and population decision-making relies on the systematic evaluation of extensive regulatory evidence. The FDA drug reviews provide detailed information on clinical trial design, enrollment criteria, sample size, randomization, comparators, endpoints, a...
