Self-harm among adolescents has become a serious public issue. Among various risk factors, parenting styles have been shown to have a significant impact. However, few studies have explored how exactly different parenting styles influence self-harm behavior. In a new study, researchers identified different parenting styles perceived by adolescent’s and clarified their link to self-harm behavior. The findings suggest that positive parenting can act as a protective shield against self-harm behavior, guiding practical intervention strategies.

Aviation’s climate impact extends beyond carbon dioxide emissions. A new study from Chalmers University of Technology and the University of Gothenburg, Sweden, and Imperial College, UK, reveals that contrails can represent a significant portion of aviation’s overall climate cost. The study also shows that climate impact can be reduced by optimising flight routes.

In a new article in Nature Communications, The social costs of aviation CO₂ and contrail cirrus, the researchers demonstrate that both CO₂ emissions and contrail formation contribute materially to aviation’s climate impact – and that the associated societal costs differ substantially depending on weather patterns and routing decisions. They find that, at the global level, contrails account for about 15 percent of aviation’s climate impact when measured in economic terms.

With heart disease as the leading cause of death worldwide, there is growing recognition that recovery is not only physical but also emotional and social. A new study shows that strong and supportive relationships can indeed improve heart health for individuals with cardiovascular disease. The work is described in an article in the Canadian Journal of Cardiology, published by Elsevier, which calls for intimate partners to be included in cardiac rehabilitation programs to support long-term heart health and quality of life for both members of the couple.
