A new study from Northern Arizona University looks at the long-term effects of restoring a forest with mechanical thinning and prescribed burns. The news is good: treated forests are healthier and more resistant to catastrophic wildfires, and those benefits seem to last. But climate change adds a wild card. KNAU’s Melissa Sevigny spoke with forest ecologist Mike Stoddard about the findings.

India’s crisis continues with 26 million confirmed coronavirus cases and three hundred thousand deaths; thousands more are reported every day. The country’s severe shortage of vaccines reveals the inequities in the coronavirus response between developed and developing nations. Amit Kumar is an epidemiologist at Northern Arizona University who researches health care disparities. He spoke to KNAU’s Melissa Sevigny about how India’s crisis is a global problem—but also deeply personal for him, because he has family and friends there suffering from unimaginable tragedy and fear.

The Navajo Nation faces a housing crisis. Many homes don’t have electricity or running water, and large families share small spaces with few options for isolating if someone gets sick with COVID-19. Carmirae Holguin has started a new nonprofit to address these issues and revitalize traditional building practices. KNAU’s Melissa Sevigny spoke with her about the Nááts'íilid Initiative.
