Article Abstract

Traditional face-to-face laboratory studies have contributed greatly to our understanding of how misinformation effects develop. However, an area of emerging concern that has been relatively under-researched is the impact of misinformation following exposure to traumatic events that are viewed online. Here we describe a novel method for investigating misinformation effects in an online context. Participants ( = 99) completed the study online. They first watched a 10-min video of a fictional school shooting. Between 5 and 10 days later, they were randomly assigned to receive misinformation or no misinformation about the video before completing a recognition test. Misinformed participants were less accurate at discriminating between misinformation and true statements than control participants. This effect was most strongly supported by ROC analyses (Cohen's = 0.59, BF10 = 8.34). Misinformation effects can be established in an online experiment using candid violent viral-style video stimuli.

Background: Postgraduate education is embracing journal clubs (JCs), which provide a platform for members to critically evaluate research articles and extract evidence-based nursing practice. The implementation of JCs by postgraduate nurses, especially in varied educational contexts such as Egypt, remains underexplored. This study aimed to explore and gain valuable insights into the professional experiences of implementing JCs among postgraduate nursing students in Egypt.

Generative artificial intelligence (AI) is rapidly transforming perioperative medicine, particularly anesthesiology, by enabling novel applications, such as real-time data synthesis, individualized risk prediction, and automated documentation. These capabilities enhance clinical decision-making, patient communication, and workflow efficiency in the operating room. In education, generative AI offers immersive simulations and tailored learning experiences that improve both technical skills and professional judgment.

Active metasurfaces incorporating electro-optic materials enable high-speed free-space optical modulators that show great promise for a wide range of applications, including optical communication, sensing and computing. However, the limited light-matter interaction lengths in metasurfaces typically require high driving voltages exceeding tens of volts to achieve satisfactory modulation. Here we present low-voltage, high-speed free-space optical modulators based on silicon-organic-hybrid metasurfaces with dimerized-grating-based nanostructures.

Binge drinking (BD) is a widespread pattern of excessive alcohol consumption among adolescents and young adults with detrimental consequences for brain development. Animal models are essential for investigating the neurobiological mechanisms underlying BD, but selecting an appropriate model is critical to ensure relevance to human behavior. This study aims to validate a murine model of (BD) using Swiss Webster mice.
