Using nanoparticles, researchers have created a sensor that selectively detects levels of cortisol, a well-known stress biomarker. Their cheap and easily reproducible device brings us a step closer to stress testing from the comfort of home.

Taking placebos fully aware that they contain no active ingredients can still significantly reduce stress, anxiety and depression according to a new study. It’s suggested that these 'non-deceptive placebos' might be an effective way of improving mental health.

In the world of dogs and cats, it wouldn't be a stretch to say that canines seem more optimistic and felines less so. But a dog's optimism can apparently be dampened by their human's emotional state, according to new research.

For the first time, scientists have uncovered the precise molecular mechanism that gives the tardigrade, one of the toughest organisms on the planet, its ability to switch on a near-invincibility cloak when faced with life-threatening conditions.

A study has found that a therapy program focusing on self-compassion and mindfulness reduced symptoms of post-traumatic stress. The intervention is promising for those who suffer from PTSD symptoms but don't meet the criteria for a formal diagnosis.

Far beyond concerns about waistlines, reaching for fatty foods during stressful times can have a dangerous impact on cardiovascular function and then significantly impair our body’s ability to return to normal after the tough time subsides.

Researchers have identified how Lactobacillus, a member of our guts’ microbiome community, affects a critical immune system protein, influencing stress levels and mental health. The findings could lead to new treatments for depression and anxiety.
