That's the suggestion from a new UCLA study that tracked levels of cortisol, a key stress hormone, among 30 Los Angeles married couples involved in one of our age's trickiest juggling acts — raising kids when both parents work full time.

Canada’s peacekeepers suffer similar rates of Post-Traumatic Stress Disorders (PTSD) as combat, war-zone soldiers, according to a London, Ont. research team.

More than a third of women surveyed about their beliefs surrounding miscarriage and birth defects said they thought that a pregnant woman's foul mood could negatively affect her baby.

One way to alleviate the pain of banging your shin while on a hike is to encounter a grizzly bear—a well-known phenomenon called stress-induced analgesia. Now, researchers have elucidated a key mechanism by which the stress hormone noradrenaline—which floods the bloodstream during grizzly encounters and other stressful events—affects the brain’s pain-processing pathway to produce such analgesia.

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a mechanical fatigue process that eventually leads to cracks and breakdown in bulk silicon crystals—a phenomenon that’s particularly interesting because it long has been thought not to exist.

Researchers have known for years that psychological trauma that results in post-traumatic stress disorder (PTSD) or depression can change how a person responds to stress.

According to a study that appears in the current issue of SCAN (Social Cognitive and Affective Neuroscience), researchers at the University of Pennsylvania School of Medicine discuss how men and women differ in their neural responses to psychological stress.

Older workers generally report low levels of work-related stress, according to a University of Michigan study of a nationally representative sample of older workers.

Researchers here have shown that in cell cultures, the stress hormone norepinephrine appears to promote the biochemical signals that stimulate certain tumor cells to grow and spread.

Researchers from Boston University School of Medicine (BUSM) conducted a nationwide survey to identify stressors perceived by pathology residents. The survey appears online in the December issue of the American Journal of Clinical Pathology.

Viral infection disrupts the normal response of mammalian cells to outside deleterious forces, cleaving and inactivating a protein called G3BP that helps drive the formation of stress granules, which shelter the messenger RNAs that carry the code for protein formation, said researchers from Baylor College of Medicine in Houston.

Researchers have uncovered a key genetic switch that chronic cocaine or stress influences to cause the brain to descend into a pathological state. In studies with mice they showed how chronic cocaine changes gene activity to enhance the addictive reward from the drug. And they showed similarly how chronic stress induces the same kinds of changes that hypersensitizes the brain, causing depression-like symptoms.
