Far from a static barrier, the brain’s extensive interface with the blood is increasingly being appreciated as an active border, one that serves not only to keep some proteins out, but to let others ...

Scientists uncover key proteins driving brain aging, offering critical insights into timing interventions to preserve brain health and combat neurodegenerative disorders. Study: Plasma proteomics ...

Some people’s brains age faster than average, some slower. Scientists quantify this “brain age gap” by subtracting a person’s chronological age from their brain’s biological age. Because aging brains ...
