It's a sound that hasn't been heard much in Arizona's grasslands since 1931.

The Navajo Nation spans three states and 27,000 square miles. Many homes are so remote and spread out that they don’t have addresses. And, that can make healthcare difficult, especially follow-up care after hospitalization. That’s why John Georgas is working on a computer project and mobile app to identify homes without street addresses to make healthcare access a little easier.

Soft ticks are arachnids, like spiders. They live in pine and hardwood forests and thrive on the blood of mice, squirrels, chipmunks and sometimes birds. They don’t usually feed on humans, but, as in the case that closed Camp Colton near Flagstaff recently, it does happen once in awhile. Northern Arizona University Forest Entomology Professor Rich Hofstetter explains.

Earthquakes can’t be predicted, but Professor Dave Brumbaugh says Northern Arizona can expect seismic activity simply because there are a number of faults here. Brumbaugh is the director of the Arizona Earthquake Information Center on the Northern Arizona University Campus. He says the Earth’s crust in the region is expanding.

Brain Food: Understanding the Land’s Role in a Changing Climate

Much of the carbon dioxide released into the atmosphere from human activities — like burning fossil fuel — is taken up as plant food. Northern Arizona University’s Debbie Huntzinger, a researcher of climate change models, says the land’s surface is currently storing more of the greenhouse gas than it’s giving off.
