Stress Genes Guide Cell Cleanup

New research has uncovered how the body clears dying cells during times of stress, shedding light on the unexpected role of classic stress-response genes. Using the model organism C. elegans, scientists tracked how these genes activate a pathway that helps remove cellular debris, a process essential for immune health and development.

Smart Floss Measures Stress Hormone for Easy, Real-Time Monitoring

Engineers have developed a novel dental floss device that can detect cortisol—a hormone linked to stress—through saliva, offering a painless, real-time method for stress monitoring. The device uses electropolymerized molecularly imprinted polymers (eMIPs), which act like custom molds to recognize specific molecules.

Midlife Cortisol Levels Linked to Alzheimer’s Risk

A new study finds that elevated cortisol levels in midlife are linked to increased brain amyloid deposition—a key marker of Alzheimer’s disease—specifically in post-menopausal women. Researchers tracked 305 cognitively healthy individuals over 15 years and discovered that high cortisol predicted amyloid buildup later in life, but only among women who had gone through menopause.
