Childhood Adversity Tied to Race-Related Differences in Brain Development
Gray matter volume in key brain regions was lower in Black children compared with white children, likely due to disparities in childhood adversity, according to data from the Adolescent Brain Cognitive Development (ABCD) study. Among children ages 9 to 10 years, white kids showed greater gray matter volumes compared with Black kids in the amygdala, […]
Social Isolation Tied to Higher Risk of Subsequent Dementia
Social isolation was linked with lower volume in brain areas related to cognition and associated with a higher risk of subsequent dementia as well, a longitudinal study showed. Among more than 460,000 participants in the U.K. Biobank, social isolation at age 57 was tied to a 26% increased risk of dementia 12 years later, independent […]
Novel theory of entropy may solve materials design issues
A challenge in materials design is that in both natural and humanmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this phenomenon for some specific materials, a general understanding of why this sometimes happens remains lacking. However, a team of Penn State researchers has come up with a […]
