Link between intelligence and longevity is mostly genetic. New research published in the International Journal of Epidemiology demonstrates that the observed tendency for people with higher intelligence to live longer is largely explained by genetic factors. By analysing data from multiple twin registries, researchers conclude that roughly 95% of the association between intelligence and lifespan … Read more

Summary: A recent review examines evidence connecting the gut microbiome to brain development and depressive disorders. The authors highlight how disruptions to gut bacteria—caused by diet, stress, antibiotics, or early-life events—may influence mental health and suggest that nutrition-based strategies could complement existing treatments. Linking the Gut Microbiome, Neurodevelopment, and Depression Overview Researchers are increasingly investigating … Read more

The results could help refine diagnosis and lead to more targeted treatments for schizophrenia. The study, published online in the journal NeuroImage, used high-resolution magnetic resonance imaging (MRI) and diffusion tensor imaging … Read more

Summary: Multisensory gamma-wave stimulation improves recognition and spatial memory in mice and reduces amyloid burden in the auditory cortex and hippocampal CA1. These findings indicate that combined sensory stimulation strengthens hippocampal function and diminishes Alzheimer’s-related pathology across the neocortex. Source: MIT By exposing mice to a coordinated combination of light and sound, MIT neuroscientists have … Read more

Our family of origin plays a powerful role in shaping who we become. From our habits and emotional responses to the choices we make in life, family dynamics influence us whether we feel close to our relatives or distant from them.
