Recursive seed amplification detects distinct α-synuclein strains in cerebrospinal fluid of patients with Parkinson’s disease

Stefan Bräuer, Iñaki Schniewind, Elisabeth Dinter et al. · 2025 · Acta Neuropathologica Communications

Parkinson's disease (PD) is a heterogeneous neurodegenerative disorder with a wide range of clinical phenotypes. Pathologically, it is characterized by neuronal inclusions containing misfolded, fibrillar alpha-synuclein (aSyn). Prion-like properties of aSyn contribute to the spread of aSyn pathology throughout the nervous system as the disease progresses. Utilizing these properties, seed amplification assays (SAA) enable the detection of aSyn pathology in living patients. We hypothesized that structurally distinct aSyn aggregates, or strains, may underlie the clinical heterogeneity of PD. To t

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

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
