Microbial diversification is maintained in an experimentally evolved synthetic community

Zahraa S. Al-tameemi, Alejandra Rodríguez‐Verdugo · 2024 · mSystems

ABSTRACT Microbial communities are incredibly diverse. Yet, the eco-evolutionary processes originating and maintaining this diversity remain understudied. Here, we investigate the patterns of diversification for Pseudomonas putida evolving in isolation and with Acinetobacter johnsonii leaking resources used by P. putida . We experimentally evolved four experimental replicates in monoculture and co-culture for 200 generations. We observed that P. putida diversified into two distinct morphotypes that differed from their ancestor by single-point mutations. One of the most prominent mutations hit

Mutualism breakdown underpins evolutionary rescue in an obligate cross-feeding bacterial consortium

Ignacio J. Melero‐Jiménez, Yael Sorokin, Ami Merlin et al. · 2025 · Nature Communications

Populations facing lethal environmental change can escape extinction through rapid genetic adaptation, a process known as evolutionary rescue. Despite extensive study, evolutionary rescue is largely unexplored in mutualistic communities, where it is likely constrained by the less adaptable partner. Here, we explored empirically the likelihood, population dynamics, and genetic mechanisms underpinning evolutionary rescue in an obligate mutualism involving cross-feeding of amino acids between auxotrophic Escherichia coli strains. We found that over 80% of populations overcame a severe decline whe

Burooj Ghani, Vincent J. Kalkman, Bob Planqué et al. · 2025 · Scientific Reports

Animal sounds can be recognised automatically by machine learning, and this has an important role to play in biodiversity monitoring. Yet despite increasingly impressive capabilities, bioacoustic species classifiers still exhibit imbalanced performance across species and habitats, especially in complex soundscapes. In this study, we explore the effectiveness of transfer learning in large-scale bird sound classification across various conditions, including single- and multi-label scenarios, and across different model architectures such as CNNs and Transformers. Our experiments demonstrate that

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

The (alleged) consequences of affective polarization: A survey experiment in nine democracies

Eelco Harteveld, Lars Erik Berntzen, Andrej Kokkonen et al. · 2026 · European Journal of Political Research

Abstract Affective polarization (or antipathy between supporters of opposing political camps) is considered a threat to societal cohesion and democratic stability worldwide. However, causal evidence of its impact remains scarce, especially outside the United States. Our study examines the individual-level consequences of affective polarization by manipulating it in a survey experiment in nine countries (Brazil, France, Germany, Italy, Poland, Spain, Sweden, the United Kingdom, and the United States; N ≈ 18,000) and subsequently assessing the downstream consequences for social avoidance and dis

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

Media consolidation and news content quality

Marcel Garz, Märt Ots · 2025 · Journal of Communication

Abstract News organizations have been under financial pressure to streamline their activities for decades. Critics argue that this pressure undermines the quality of news, posing a severe threat to democracy. However, the effects of media consolidation on news quality are theoretically ambiguous and empirical evidence is scarce. To address this gap, we study the case of the Swedish newspaper industry between 2014 and 2022, a period where more than half of the country’s newspapers changed their owners. We collect over 2 million articles from 108 newspapers and apply state-of-the-art computation

Orbital Eccentricity in a Neutron Star–Black Hole Merger

Gonzalo Morrás, G. Pratten, P. Schmidt · 2026 · The Astrophysical Journal Letters

Abstract The observation of gravitational waves (GWs) from merging black holes and neutron stars provides a unique opportunity to discern information about their astrophysical environment. Two signatures that are considered powerful tracers to distinguish between different binary formation channels are general relativistic spin-induced orbital precession and orbital eccentricity. Both effects leave characteristic imprints in the GW signal that can be extracted from observations. To date, neither precession nor eccentricity has been confidently discerned in merging neutron star–black hole binar
