Board Exam Scores Predict Patient Outcomes: A Large-Scale Study

2025-03-01

A new study from Harvard Medical School and the American Board of Internal Medicine (ABIM) reveals a significant link between internal medicine board certification exam scores and patient outcomes. Patients of physicians scoring higher on the exam had lower 7-day mortality rates and readmission rates, suggesting the exam effectively assesses clinical competence. The study analyzed data from nearly 7,000 newly trained hospitalist physicians, controlling for factors like hospital resources and patient populations. While in-training milestone ratings showed no correlation with patient outcomes, the research highlights the importance of evidence-based assessment in physician training.

Genomics Reveals the Origin of Indo-European Languages: An Ancient Secret from the Lower Volga

2025-02-10

A groundbreaking genomics study has unearthed the surprising origins of the Indo-European language family. Researchers discovered that an ancient population from the Caucasus Lower Volga region was the ultimate source of Indo-European languages, sharing close connections with later Yamnaya culture and Anatolian language speakers. The Yamnaya culture spread Indo-European languages across Europe and into the Indian subcontinent through population expansion, with their unique cultural traditions, like kurgan burials, also stemming from the Caucasus Lower Volga people. This research not only reshapes our understanding of Indo-European origins but also showcases the immense potential of ancient DNA technology in tracing human history and cultural diffusion.
