Bilingual Brains Build Stronger Connections Learning a second language, especially in childhood, can boost brain connectivity and support lifelong cognitive flexibility. New research shows bilingual brains have more efficient networks, benefiting attention and brain health.

New research shows maternal affection in childhood predicts key personality traits like conscientiousness, openness & agreeableness—traits linked to lifelong success. Early parenting matters more than we thought. https://lnkd.in/gkXXV5hC

AI Reveals What Keeps People Committed to Exercise A new study has used machine learning to identify the key predictors of physical activity adherence, analyzing data from nearly 12,000 individuals. The research found that time spent sitting, gender, and education level were the strongest indicators of whether someone met weekly exercise guidelines. https://lnkd.in/gKD35c33

Disrupted Myelin Protein Implicated in Schizophrenia A new study has identified the protein hnRNP A1 as a key player in the production and maintenance of myelin, the fatty sheath that insulates nerve fibers in the brain. https://lnkd.in/e3vUZCAX

Potential Depression Risk Linked to Ozempic-Like Drugs A new international study reveals a possible connection between GLP1 receptor agonists—used in drugs like Ozempic—and increased risk of depression and suicidal ideation, especially in people with low dopamine function. https://lnkd.in/ga8ijzPX

Negative Distractions Most Disrupt Attention and Linger in Memory A new study reveals that upsetting distractions significantly impair our ability to sustain attention and also linger more strongly in memory. https://lnkd.in/git-UPZ5

How Intent Shapes Perception of Action A groundbreaking study used a brain-machine interface to explore how intentions, actions, and their outcomes are temporally linked in the human brain. https://lnkd.in/grqZUafp

Gold Nanoparticles Could Restore Vision in People with AMD Gold nanoparticles + infrared light = restored vision? A new Brown University study shows that injecting gold particles into the retina can bypass damaged photoreceptors and reawaken the visual system—no surgery required. A new frontier in sight. https://lnkd.in/gCAK7jnx

How Age, Sex, and Genetics Shape Blood Biomarkers for Dementia A new study reveals how age, sex, menopause, and genetics influence key blood biomarkers linked to dementia risk. Researchers analyzed data from over 1,000 people, measuring three biomarkers over a 17-year period and comparing results between those who developed dementia and those who did not. https://lnkd.in/gMwks-AC
