Today marks three years since a shooting on Northern Arizona University’s campus left three students injured and one dead. In the days that followed, NAU psychologist Heidi Wayment surveyed students to learn how they responded—with grief, depression, or anxiety—and also what helped them heal. KNAU’s Melissa Sevigny spoke with Wayment about her recently published findings.

Wildfire seasons in the West are growing longer and more intense. So more prescribed burns are happening to protect forest towns in places like northern Arizona. That can be hard on the health of residents and firefighters. KNAU’s Melissa Sevigny reports, not much is known about the long-term effects of breathing forest fire smoke.

Regular exercise is good for a lot of things: strengthening muscles, decreasing body fat, even helping us sleep better. Now, new research shows it’s also good for the trillions of micro-organisms in our intestines, which have a profound effect on other systems in our bodies.

Summers on the Navajo Nation can be scorching, and many homes there don’t have air conditioners or swamp coolers. But a group of eighth grade students at The STAR School, near the edge of the Navajo Nation, has come up with a solution: a low-cost evaporative cooler they plan to give away to elders. As KNAU’s Melissa Sevigny reports, the project won a statewide science and technology prize.
