Research at Binghamton University found that low self-esteem is associated with high opioid use and serves as a mediator between life stressors and opioid abuse. The study suggests individuals with poor self-esteem may seek opioids to cope with stressors like health, family, or romance problems.
Researchers in India used GPS and satellite data to track crustal deformation around reservoirs, finding that seasonal filling can reduce the strength of nearby faults and trigger earthquakes. Even small reservoirs can cause significant deformation capable of triggering an earthquake if there are critically stressed faults in the region.
Researchers found that spontaneous self-distancing predicts whether awe has a positive or negative effect on people. Awe can lead to a sense of smallness, making obstacles seem insignificant, but also a perception of capabilities as insignificant, making stressors unmanageable.

Mindfulness training and clear policies can help mitigate these negative impacts.
Researchers mapped global marine wilderness, finding only 13% of the world's ocean can still be classified as wilderness. The remaining areas are mostly located in remote regions, such as Arctic and Pacific Island nations, while coastal regions have almost no wilderness left. Protecting what remains is crucial to preserve biodiversity.
