Almost one in five adults in the U.S. lives with a mental illness. That statistic is similar worldwide, with an estimated 450 million people currently dealing with a mental or neurological disorder. Of those, only about a third seek treatment. Interacting with nature is starting to be recognized as one way to improve mental health.

The new study led by the University of Washington shows that analyzing the ear stone — called an otolith — of wild Sockeye Salmon in Alaska reveals how key salmon habitat shifts year-to-year. Published in Science on May 23, the study suggests that different parts of the watershed are hot spots for salmon production and growth. These favorable locations change year-to-year depending on climate conditions and their impacts on local landscapes, which affects the value of the habitats.

Just over one-third of the world’s 246 longest rivers remain free-flowing, according to a new study published May 8 in Nature. Dams and reservoirs are drastically reducing the diverse benefits that healthy rivers provide to people and nature across the globe. A team of 34 international researchers from McGill University, World Wildlife Fund, the University of Washington and other institutions assessed the connectivity status of 12 million kilometers of rivers worldwide, providing the first-ever global assessment of the location and extent of the planet’s remaining free-flowing rivers.
