Today marks three years since a shooting on Northern Arizona University’s campus left three students injured and one dead.

KNAU’s Melissa Sevigny spoke with Wayment about her recently published findings.

For some, autumn means celebrating by raising a glass of a crisp lager or October ale. But the Nature Conservancy wants patrons of local breweries to know you can’t have beer without a healthy forest.

A Flagstaff astronomer turned up a rare object at the edge of the solar system that strengthens the case for an undiscovered massive planet. KNAU’s Melissa Sevigny reports.

Some people collect pinyon pine nuts this time of year for a tasty autumn treat. Others sell them for extra income.

KNAU’s Melissa Sevigny spoke with her in the woodlands east of Flagstaff.
