Sleep Duration Linked to Accelerated Aging

Researchers have discovered a "U-shaped" link between sleep and the biological clocks of 17 different organ systems. Sleeping fewer than 6 hours or more than 8 hours accelerates the aging of your heart, lungs, and immune system. By analyzing data from half a million people, the study identifies a "longevity window" of 6.4 to 7.8 hours, highlighting sleep as a vital, modifiable lifestyle factor for systemic health.

Targeting Brain “Clean-up” Cells to Fight Dementia

Researchers discovered that dysregulated circadian rhythms cause microglia, the brain’s immune cells, to become "stress-primed" and malfunction. This state prevents them from clearing amyloid plaques, accelerating dementia risk. Now, using DARI seedling grants, Souza is testing a stem-cell-derived "EV therapy" designed to keep these cells healthy and prevent neuroinflammation.

Unpaid Labor Predicts Psychological Distress

Total working hours, combining paid jobs and unpaid domestic labor, is the key driver of poor mental health and sleep deprivation in women. Researchers call for policy changes that account for "invisible work" to close the gender health gap.

How Slow Waves During Sleep Take Over to Clear Metabolic Trash

Researchers have developed a non-invasive MRI method to measure the brain’s self-cleansing process. The study reveals that during sleep, vascular pulsations take control of brain dynamics to accelerate waste removal.
