A corrected analysis of melanoma patient data reveals limitations in using non-nodal metastases to predict sentinel lymph node involvement. The finding matters to oncologists and cancer centers refining staging protocols, as it suggests current predictive models may not reliably guide treatment decisions for early-stage skin cancer patients.EN

A new study finds that meme-based content normalized far-right narratives across European social media during the 2024 parliament elections, reaching mainstream audiences who wouldn't engage with overt extremist material. For policy makers and platforms, the finding suggests that casual, humorous online content poses a greater electoral threat than traditional extremist propaganda.EN

Researchers have discovered that ketamine's antidepressant properties operate independently from its dissociative effects—a finding that could enable development of faster-acting psychiatric treatments without the disorienting drawbacks. The discovery, based on brain imaging of hundreds of patients, suggests drugmakers can target specific neurological pathways to improve mental health outcomes.EN

A comprehensive global analysis reveals that suboptimal nutrition causes over 4 million deaths annually from ischemic heart disease, with the burden falling heaviest on poorer countries. The finding identifies specific dietary gaps—nuts, whole grains, and fruits—as the primary culprits, offering a roadmap for food policy and public health interventions to reduce preventable mortality.EN

A new EU-wide analysis shows that a modest 15% increase in physical activity could avert nearly 24,000 premature deaths from heart disease, cancer, and diabetes by 2030. For health systems and employers, the finding underscores exercise as a high-impact, low-cost lever for reducing the burden of chronic disease.EN

A major meta-analysis of 28 studies identifies specific patient characteristics that predict stroke recurrence over a decade, enabling clinicians to better target prevention efforts. The findings could reshape how hospitals and insurers allocate resources for post-stroke management and secondary prevention programs.EN

Cancer incidence will jump from 20 million cases annually today to 31 million by 2050, driven largely by aging populations and lifestyle risk factors, according to a comprehensive analysis of 47 cancer types across 204 countries. The projection carries major implications for healthcare systems, pharmaceutical markets, and public health budgets worldwide.EN

Researchers have developed an artificial intelligence system that interprets knee X-rays with higher accuracy than traditional radiologist assessment, addressing a major source of diagnostic inconsistency. The advance could accelerate early detection of osteoarthritis—a condition affecting millions—and reduce the clinical variability that currently depends on individual radiologist expertise.EN

Japan's cardiac societies released updated clinical guidance on diagnosing and treating heart failure, reflecting advances in drug therapies and device interventions since the last major revision. The refresh matters for hospitals, insurers, and drugmakers operating in Asia's second-largest economy, as it will likely shift treatment protocols and influence which therapies gain preferred status in clinical practice.EN

A new study shows preschool teachers struggle to balance structured science lessons with free play—a tension that affects early learning outcomes. Researchers found that teacher training programs focusing on "play-responsive" methods can help educators recognize teachable moments in play, potentially improving both science understanding and child development.EN

A new study shows that when people consider how their choices affect descendants, they become significantly more likely to back costly climate policies. The finding suggests policymakers can shift public opinion by reframing climate action as an intergenerational responsibility—particularly among women and non-binary groups.EN
