Penn State researchers have found that the signal of global brain activity is coupled to movement of cerebral spinal fluid in humans. It appears that the coupled movement cleans out the brain’s toxins as a person sleeps. The weaker the coupled movement, the higher the risk the person could develop Alzheimer’s disease. The signal can viewed via non-invasive brain imaging and could serve as a clinical marker to help in diagnosis.

First described in 2012, the glymphatic system acts as a waste management system, washing out the proteins and other buildup that can hinder brain activity. The critical component of the system is the cerebrospinal fluid flow, according to Liu, which his research suggests is activated by the global BOLD signal activation. In sleep, the glymphatic system can speed up its cleaning processes significantly.

UNIVERSITY PARK, Pa. Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with decreased lifespan in humans; therefore, the team s findings may have implications for human longevity. Human men have shorter telomeres than women, which may partly explain why they have shorter lifespans of about seven years, said Tracy Langkilde, professor and Verne M. Willaman dean of the Eberly College of Science. Our study shows that stress experienced by mothers during gestation could further shorten the telomeres, and therefore the lifespans,
