Oral Bacteria Diversity Linked to Depression Symptoms

A new study reveals that lower diversity of microbes in the mouth is associated with greater symptoms of depression. Researchers analyzed data from over 15,000 U.S. adults, comparing their mental health surveys with saliva samples to assess microbial diversity.

Out-of-Body Experiences Help the Mind Escape from Trauma

New research suggests that out-of-body experiences (OBEs) may serve as coping mechanisms triggered by trauma, rather than symptoms of mental illness. Based on data from over 500 individuals, those who had OBEs reported higher rates of mental health conditions, but also described lasting benefits from their experiences.

Weekend Catch-Up Sleep Boost May Lower Teen Anxiety

A new study reveals that teenagers who get moderate catch-up sleep—up to two extra hours—on weekends report fewer symptoms of anxiety. Sleeping significantly more or less on weekends than on weekdays, however, was linked to higher anxiety levels.

Social Status and Genes Interact to Shape the Aging Brain

A global study of nearly one million individuals has identified hundreds of genetic regions linked to socioeconomic status, revealing a shared genetic signal across income, education, occupation, and deprivation. Researchers found that about 9% of the variation in socioeconomic status could be attributed to genetics, while the rest was driven by social and environmental factors.

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.

Childhood Trauma Rewires the Brain Through Inflammation

Childhood trauma doesn't just leave psychological scars—it biologically reshapes the brain through chronic neuroinflammation and structural changes, increasing vulnerability to psychiatric disorders later in life. New research shows that early adversity can reprogram immune responses, altering lifelong mental health outcomes.

Oral-Gut Bacteria Linked to Dementia Risk in Parkinson’s Disease

A new study has found that bacteria from the mouth may migrate to the gut and contribute to cognitive decline in people with Parkinson’s disease. Researchers identified harmful microbes and their toxins in the gut of Parkinson’s patients with dementia, suggesting a possible link between oral hygiene, gut health, and neurodegeneration.

Healthy Habits May Offset Brain Aging Linked to Shorter Telomeres

New research shows that healthy lifestyle choices can reduce the risk of stroke, dementia, and depression—even in people with biologically shortened telomeres. Telomeres are protective DNA caps that naturally shrink with age and environmental stress, increasing vulnerability to age-related brain diseases.

Smelling Food Triggers Fullness, But Only in Lean Brains

Researchers have identified a new brain pathway in mice that links the smell of food to feelings of fullness—offering insight into how scent influences appetite. When lean mice smelled food, a group of nerve cells in the medial septum activated rapidly, signaling satiety and reducing food intake.

Negative Surroundings Skew Emotions in People with Depression

People with depressive symptoms are more likely to interpret neutral images as negative when those images are surrounded by unrelated negative visuals. This emotional “spillover” effect shows how peripheral cues—like background imagery or context—can shape our emotional responses more than we realize.

How Serotonin Circuits Learn from Motion to Regulate Behavior

Scientists have uncovered how serotonergic neurons in larval zebrafish process visual information tied to movement to determine when and how much serotonin to release. This neuromodulator fine-tunes the fish’s swimming effort, adjusting behavior based on the effectiveness of past actions.

Fast-Track to Happiness: One Week of Micro-Acts Makes a Difference

A new study has shown that just seven days of small, daily acts of kindness and gratitude can significantly improve emotional wellbeing. In the web-based Big Joy Project, nearly 17,600 participants from around the world performed micro-acts like sharing joyful moments and listing things they’re grateful for.
