Ozone (O3) exposure may reduce the availability of oxygen in the body, resulting in arterial stiffening due to the body’s natural response to create more red blood cells and hemoglobin, according to a study published today in JACC, the flagship journal of the American College of Cardiology.

The Great Salt Lake, the largest saltwater lake in the Western Hemisphere, reached historic low levels in 2022, raising economic, ecological and public health concerns for Utah. New research from Portland State is believed to be the first peer-reviewed study that quantifies the contributing factors to the record low water volume levels, which the researchers say is important for anticipating and managing future lake changes.

In the face of growing global challenges such as climate change, pandemics, and threats to democratic values, traditional behavioral policy approaches are increasingly coming into question.

In response, boosts are gaining importance. These interventions are designed to enhance individuals' decision-making and self-control skills, as scientists from the Max Planck Institute for Human Development explain in the Annual Review of Psychology—one of psychology’s most cited journals.
