Mining, grazing, and drought have all taken a toll on land in the Southwest, including the Navajo Nation. Replanting the damaged landscape isn’t easy, because it’s difficult to find local seeds adapted to the region and climate.

The University of Arizona is unrolling a statewide program to test 250,000 health care workers and first responders in Arizona for antibodies against COVID-19. KNAU’s Melissa Sevigny reports.

Scientists use different models to try to forecast the spread of the coronavirus disease. The models can inform public health decisions like when to reopen businesses, but—just like weather forecasting—they’re not perfect at predicting the future. KNAU’s Melissa Sevigny spoke with computer modeler Joe Mihaljevic of Northern Arizona University for our weekly update on the science of COVID-19.

National parks and other protected areas are critical conservation spots for wildlife. But, they’re often too isolated to support natural migration and dispersal. That’s why the nonprofit Wildlands Network is working with coalition partners on a bold vision, known collectively as the ‘Western Wildway’. It’s a 6,000 mile-long wildlife corridor aimed at connecting 20 separate core reserves from Mexico to Alaska.

More than fifteen hundred clinical trials are underway worldwide related to the coronavirus disease. Many of these experiments are focused on developing new drugs and therapies to treat patients. Along with public health measures, those are an important line of defense against COVID-19 until a vaccine is created. In KNAU’s weekly update on the science of COVID-19, Melissa Sevigny spoke with infectious disease expert Dr. Paul Keim about what’s promising and what’s not.
