How Stress Types Differently Impact Brain and Behavior

Stress is a universal experience, but not all stress affects the brain in the same way. A new study in rats reveals that acute stress provokes anxiety-like behaviors, especially in males, while chronic stress is more strongly tied to depressive symptoms.

Women’s Scent During Ovulation Alters Male Stress and Attraction

Certain scent compounds in female body odor, which increase during ovulation, can subtly influence male perception and stress levels. When these compounds were added to model armpit odors, men found the scents more pleasant and rated images of women as more attractive and feminine.

Pregnancy Stress Disrupts Baby’s Microbiome, Increasing Depression Risk

Prenatal stress in mothers can leave a lasting imprint on their offspring, predisposing them to depression-like behaviors. Researchers found that maternal stress disrupts the gut microbiome and metabolite production, which are vertically transmitted to the young.

Neurons Store Backup Energy to Power the Brain Under Stress

New research has uncovered that neurons store their own glycogen, acting as “backup batteries” to keep the brain functioning during energy stress. Using worms and advanced biosensors, scientists found that neurons can tap into glycogen reserves, especially when oxygen or mitochondrial function is limited.

Anxious Mondays Leave Lasting Mark on Stress

A new study reveals that anxiety felt on Mondays uniquely elevates stress hormones, even in retirees, with potential consequences for heart health. Researchers found older adults who reported Monday anxiety had 23% higher long-term cortisol levels than peers anxious on other days.

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.

Stress-Linked Brain Pathway Disrupts Sleep and Memory

New research reveals a stress-sensitive neural pathway that impairs both sleep and memory in male mice. Scientists activated neurons in the paraventricular nucleus (PVN) of the hypothalamus, known for their role in stress response, which caused sleep loss and poor memory performance.

Chronic Stress Quietly Raises Your Stroke Risk

Chronic stress is increasingly recognized as a contributor to stroke risk by intensifying conditions like high blood pressure, inflammation, and unhealthy lifestyle habits. While stress isn't as easily measured as cholesterol or blood pressure, long-term exposure to it can set the stage for vascular damage and increase both ischemic and, less commonly, hemorrhagic stroke risk.
