Growing microscopic organisms in a lab to conduct biological warfare might sound like the makings of a science fiction movie. But in the case of the bark beetle, it's real. An entomologist at Northern Arizona University is using a fungus to combat the beetles' deadly attack on forests across the West. As Arizona Public Radio's Bonnie Stevens reports, the fungus is the latest in a string of unconventional methods to stop the bugs' rampage.

If you’re one of those people who puts on weight while another person eating the same meal doesn’t, blame your gut!

It's a sound that hasn't been heard much in Arizona's grasslands since 1931. That's when the animals were thought to have gone extinct after a strain of plague nearly wiped out their main food source, prairie dogs.

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.
