Gut Blockage Linked to Prolonged Sleep and Food Avoidance

Mirroring human neonatal obstructions like meconium ileus, this trial establishes Drosophila as an essential model to decipher how mechanical gut signals directly override central sleep-wake and appetite pathways.

Feeling Older Than Your Age Triggers Insomnia

Adults who feel older than their chronological age report significantly worse sleep outcomes, including elevated insomnia symptoms, lower sleep regularity, and greater sleep-related daytime impairment.

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.

Napping Patterns Predict Mortality Risk

A 19-year study finds that frequent, long, and morning naps in older adults are associated with higher mortality, acting as a warning sign for underlying disease.

Double Shifts Wreck the Body’s Stress Rhythm

Double shifts cause a two-fold increase in cortisol levels at midnight. Researchers warn that extended nursing schedules disrupt the body's natural stress rhythm and increase physiological strain.

Test Maps Circadian Rhythm Via Hair Sample

Researchers developed a non-invasive hair-follicle test to determine a person's internal clock. Analyzing 17 genes, the study reveals how age, gender, and especially lifestyle synchronize our biological rhythms.

Teen’s Internal Clock Controls Their Cravings

A new study shows that sleep timing is the "lever" for teen heart health. Night owls eat more calories and move less, especially during the school year when their internal clocks clash with early start times.

Physical Activity and Early Rising Linked to Lower ALS Risk

New research suggests that "early birds" and those who stay active have a 20-26% lower risk of developing the neurodegenerative disease ALS.

Working Nights May Increase Cancer Risk

Chronic circadian disruption — such as night-shift work, irregular schedules, or frequent jet lag — accelerates the development and spread of aggressive breast cancer. Researchers found that disrupted internal clocks not only weaken immune defenses but also reshape healthy breast tissue, creating conditions that tumors exploit.

Cancer Disrupts the Brain’s Internal Clock

Breast cancer can rapidly derail the brain’s day-night regulation of stress hormones, even before tumors are detectable. In mice, the disease flattens normal corticosterone rhythms by altering hypothalamic neuron activity, which may worsen outcomes and mimic symptoms often seen in cancer patients, such as insomnia and anxiety.
