Obesity and climate change: co-crises with common solutions

Paul Behrens, Catherine M. Champagne, Jason C. G. Halford et al. · 2025 · Frontiers in Science

The global obesity crisis involves an unprecedented and rapid change to the human phenotype. Conferring vast levels of avoidable morbidity and mortality at enormous cost, it has proved refractory to previous policy-led action. This article reviews recent developments in our understanding of obesity and its links to the climate co-crisis, aiming to inform evidence-based, societal-level actions to address both. Recent therapeutic developments now offer transformative interventions for millions of people living with obesity. However, treating all affected adults and children with major bariatric

An App Call a Day Keeps the Patient Away? Substitution of Online and In-Person Doctor Consultations Among Young Adults

Lina Maria Ellegård, Gustav Kjellsson, Linn Mattisson · 2026 · The Economic Journal

Abstract The emergence of markets for on-demand online physician consultations —direct-to-consumer telemedicine (DCT) — is currently transforming many healthcare settings. DCT may be a cost-effective substitute for in-person consultations, but the convenience of seeking DCT may increase the demand for the service and consequently also the costs for health insurers. To causally assess the degree to which DCT consultations substitute for in-person primary care consultations, we exploit exogenous changes in patient fees in a fuzzy difference-in-discontinuities analysis of young adults in Sweden.

The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the X-Rays and Radio

A. J. Nayana, R. Margutti, Eli Wiston et al. · 2025 · The Astrophysical Journal Letters

Abstract We present X-ray (0.3–79 keV) and radio (0.25–203 GHz) observations of the most luminous fast blue optical transient (LFBOT) AT 2024wpp at z = 0.0868, spanning 2–280 days after first light. AT 2024wpp shows luminous ( L X ≈ 1.5 × 10 43 erg s −1 ), variable X-ray emission with a Compton hump peaking at δt ≈ 50 days. The X-ray spectrum evolves from a soft ( F ν ∝ ν −0.6 ) to an extremely hard state ( F ν ∝ ν 1.26 ) accompanied by a rebrightening at δt ≈ 50 days. The X-ray emission properties favor an embedded high-energy source shining through asymmetric expanding ejecta. We detect radi

Mitochondrial Health Through Nicotinamide Riboside and Berberine: Shared Pathways and Therapeutic Potential

F Visalli, Matteo Capobianco, F. Cappellani et al. · 2026 · International Journal of Molecular Sciences

Mitochondrial dysfunction represents a central hallmark of aging and a broad spectrum of chronic diseases, ranging from metabolic to neurodegenerative and ocular disorders. Nicotinamide riboside (NR), a vitamin B3 derivative and efficient precursor of NAD+ (nicotinamide adenine dinucleotide), and berberine (BBR), an isoquinoline alkaloid widely investigated in metabolic regulation, have independently emerged as promising mitochondrial modulators. NR enhances cellular NAD+ pools, thereby activating sirtuin-dependent pathways, stimulating PGC-1α–mediated mitochondrial biogenesis, and triggering

Adjunctive Therapies in Periodontitis: Current Concepts and the Future

Rafael Scaf de Molon, João Paulo Steffens, Érica Dorigatti de Ávila et al. · 2026 · Journal of Periodontal Research

Periodontitis is a chronic, host-mediated inflammatory disease in which microbial dysbiosis and dysregulated immune responses drive the destruction of tooth-supporting tissues. Although conventional therapy remains centered on mechanical biofilm control, persistent inflammation and alveolar bone loss in susceptible individuals underscore the need for adjunctive strategies. Translating preclinical discoveries into predictable clinical outcomes, however, remains a major challenge in periodontal research.

Challenges in mimicking hypoxia: insights into HIF-regulated MiRNA expression induced by DMOG and CoCl2

Anna Barton, Maciej Jaśkiewicz, Anna Więch -Walów et al. · 2025 · Cell Communication and Signaling

Abstract The cellular and tissue response to acute hypoxia is mediated by a complex adaptive response initiated by hypoxia-inducible factors (HIF) 1 and 2. HIF proteins are key transcription factors that modulate gene expression to adapt cells to the low oxygen tension. Cellular studies of hypoxia have used the low oxygen model by using hypoxia chambers to monitor the gene expression changes, while others have utilized hypoxia mimetics in normoxic conditions. Here, we provide a comparison of the utility and limitations of two hypoxia mimetics by studying the changes in the miRNA and mRNA expre

Attending Church Encourages Acceptance of Atheists? Suppression Effects in Religion and Politics Research

Paul A. Djupe, Amanda Friesen, Andrew R. Lewis et al. · 2025 · Political Behavior

Abstract A proliferation of religion variables presents opportunities for those studying religion and politics in the U.S. However, many studies in this growing subfield demonstrate the pitfalls of reporting the “independent” effects of variables without qualification. This is especially evident in work on Christian nationalism where researchers often make the claim that worship attendance promotes more pro-social or liberal outcomes, while Christian nationalism promotes more conservative and less pro-social outcomes. We demonstrate that this finding—and others like it—represents a new version

Firm-level climate sentiments, climate politics and implied cost of equity capital

Katsiaryna Salavei Bardos, Dev R. Mishra, Hyacinthe Somé · 2025 · Journal of Corporate Finance

In a sample of U.S. firms, we find strong evidence that firms' implied cost of equity is decreasing in a novel proxy of firm-level climate change sentiments of earnings call participants, supporting prior literature that shows investors demand higher returns from their investments in brown firms and lower returns from that in green firms. This effect, however, is particularly pronounced for the firm-years headquartered in the states experiencing higher than median per-capita energy related CO2 emissions, those headquartered in climate related disaster intensive counties and those headquartered

Comparative analysis of supervised and self-supervised learning with small and imbalanced medical imaging datasets

Andrea Espis, Chiara Marzi, Stefano Diciotti · 2025 · Scientific Reports

Self-supervised learning (SSL) in computer vision has shown its potential to reduce reliance on labeled data. However, most studies focused on balanced, large, broad-domain datasets like ImageNet, whereas, in real-world medical applications, dataset size is typically limited. This study compares the performance of SSL versus supervised learning (SL) on small, imbalanced medical imaging datasets. We experimented with four binary classification tasks: age prediction and diagnosis of Alzheimer's disease from brain magnetic resonance imaging scans, pneumonia from chest radiograms, and retinal dise

Junyao Li, Ming-Yang Zhuang, Yue Shen et al. · 2025 · The Astrophysical Journal

Abstract Kiloparsec-scale dual and offset active galactic nuclei (AGNs) are signposts of accreting supermassive black holes (SMBHs) triggered during late-stage galaxy mergers, offering crucial insights into the coevolution of SMBHs and galaxies. However, robustly confirmed systems at high redshift (e.g., z > 1) are scarce and biased toward the most luminous and unobscured systems. In this study, we systematically search for kiloparsec-scale (projected separation <15 kpc) dual and offset AGNs around 571 moderate-luminosity, X-ray-selected AGNs, including the obscured population, utilizing

We perform the first search for ultralight dark matter using a magnetically levitated particle. A submillimeter permanent magnet is levitated in a superconducting trap with a measured force sensitivity of 0.2 fN/sqrt[Hz]. We find no evidence of a signal and derive limits on dark matter coupled to the difference between baryon and lepton number, B-L, in the mass range (1.10360-1.10485)×10^{-13} eV/c^{2}. Our most stringent limit on the coupling strength is g_{B-L}≲2.98×10^{-21}. We propose the POLONAISE (Probing Oscillations using Levitated Objects for Novel Accelerometry In Searches of Exotic
