Sustaining Exposure to Fact-Checks: Misinformation Discernment, Media Consumption, and Its Political Implications

Jeremy Bowles, Kevin Croke, Horacio Larreguy et al. · 2025 · American Political Science Review

Exposure to misinformation can affect citizens’ beliefs, political preferences, and compliance with government policies. However, little is known about how to durably reduce susceptibility to misinformation, particularly in the Global South. We evaluate an intervention in South Africa that encouraged individuals to consume biweekly fact-checks—as text messages or podcasts—via WhatsApp for six months. Sustained exposure to these fact-checks induced substantial internalization of fact-checked content, while increasing participants’ ability to discern new political and health misinformation upon

Women’s environmental quality of life is key to their overall quality of life and health: Global evidence from the WHOQOL-100

Suzanne M. Skevington, Kara Schick‐Makaroff, Christine Rowland et al. · 2024 · PLoS ONE

Gender inequalities in health-related quality of life (QoL) are generally few and small, even in large surveys. Many generic measures limit assessment to QoL overall and its physical and psychological dimensions, while overlooking internationally important environmental, social, and spiritual QoL domains. Unique cross-cultural legacy data was collected using four WHOQOL-100 surveys of adults living in 43 cultures world-wide (17,608 adults; ages 15-101). It was first used to examined gender profiles of its five QoL international domains, and their component facets. Few significant gender differ

Using Solid-State NMR to Understand the Structure of Plant Cellulose

Rosalie Cresswell, Parveen Kumar Deralia, Yoshihisa Yoshimi et al. · 2025 · Journal of the American Chemical Society

High Resolution Image Download MS PowerPoint Slide The structure of plant cellulose microfibrils remains elusive, despite the abundance of cellulose and its utility in industry. Using 2D solid-state NMR of 13 C-labeled never-dried plants, six major glucose environments are resolved, which are common to the cellulose of softwood, hardwood, and grasses. These environments are maintained in isolated holocellulose nanofibrils, allowing more detailed microfibril characterization. We show that there are only two glucose environments that reside within the microfibril core. These have the same NMR 13

Low molecular weight organic acids mobilize soil organic phosphorus for enzymatic hydrolysis in a temperate montane peatland

Yuchen Suo, Tong Li, Christian von Sperber et al. · 2025 · Biogeochemistry

Abstract The stability of carbon (C) stocks in peatlands is intricately linked to phosphorus (P) bioavailability. Given that organic P compounds (P o ) can make up to 89% of total soil P in these ecosystems, it is vital to understand their role in regulating plant productivity and organic matter decomposition. Despite this significance, the mechanisms controlling P bioavailability remain poorly understood. Plants and soil microorganisms primarily regulate the release of soil P via low-molecular-weight organic acids (LMWOAs) and modulate the hydrolysis of P o through phosphatase enzymes, partic

Null effect of perceived drum pattern complexity on the experience of groove

Olivier Senn, Florian Hoesl, Toni Bechtold et al. · 2024 · PLoS ONE

There is a broad consensus in groove research that the experience of groove, understood as a pleasurable urge to move in response to music, is to some extent related to the complexity of the rhythm. Specifically, music with medium rhythmic complexity has been found to motivate greater urge to move compared to low or high complexity music (inverted-U hypothesis). Studies that confirmed the inverted-U hypothesis usually based their measure of complexity on the rhythmic phenomenon of syncopation, where rhythms with more and/or stronger syncopation are considered to be more complex than less synco

Eco-evolutionary dynamics lead to functionally robust and redundant communities

Lorenzo Fant, Iuri Macocco, Jacopo Grilli · 2026 · PLoS Computational Biology

Microbial communities are taxonomically diverse and variable: species presence and abundances widely fluctuate over time, space, and even across biological replicates under controlled experimental conditions. However, environmental conditions exert strong selection on the traits of community members and their functions. Similar environmental conditions are expected to produce functionally similar communities. This environmental selection, combined with taxonomic variability, leads to the influential concept of functional redundancy - the idea that many species can perform the same function, al
