Scientists Create Tool to Detect Genes Associated with Psychiatric, Brain Diseases
Scientists at the UNC School of Medicine and colleagues created a new computational tool called H-MAGMA to study the genetic underpinnings of nine brain disorders, including the identification of new genes associated with each disorder.

Read moreNeighborhood Features and One’s Genetic Makeup Interact to Affect Cognitive Function
Few studies have examined how the neighborhood’s physical environment relates to cognition in older adults. Researchers categorized 4,716 individuals by apolipoprotein E (APOE) genotype – a genetic risk factor for Alzheimer’s disease (AD) to determine if there are cognitive benefits of living in neighborhoods with greater access to social, walking and retail destinations. Results showed that the positive influence of neighborhood environments on cognition are strongest among those who are at the lowest risk for AD, specifically APOE ε2 carriers.

Ever wonder how mice talk to each other? We don’t have a dictionary quite yet, but UD neuroscientist Josh Neunuebel and his lab have linked the ultrasonic vocalizations made by mice with specific behaviors. It’s a significant advance of our understanding of communication science.

Subtle Decline in Cognition Predicts Progression to Alzheimer’s Pathology
Researchers at UC San Diego School of Medicine report that abnormal levels of beta-amyloid plaques in brain predict cognitive decline and higher risk of developing Alzheimer’s disease, but also that cognitive performance predicts progression from normal to abnormal levels of beta-amyloid.

Researchers trained machine learning algorithms on data from more than 62,000 patients with a meningioma. Their goal was to find statistical associations between malignancy, survival, and a series of basic clinical variables including tumour size, tumour location, and surgical procedure.
Des chercheurs ont entraîné des algorithmes d’apprentissage automatique à partir des données de plus de 62 000 patients ayant un méningiome. L’objectif était de déceler des associations statistiques entre la malignité, le temps de survie et d’autres variables cliniques de base telles que la taille de la tumeur, son emplacement et la nature de l’intervention chirurgicale effectuée.
