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! Greg Caporaso says it’s all about the microbiome — or the microbes living in our bodies — that determines how many calories we extract from food and also, how susceptible we are to disease.
Thousands of scientists worldwide are studying the environmental impact of climate change. But now, two professors of English are studying its emotional impact. SueEllen Campbell and John Calderazzo are co-directors of a climate change outreach and discussion group at Colorado State University. And, they recently visited Northern Arizona University to share this message about the Earth’s changing climate:
If you've clicked on the audio link for this story, then the sound you're hearing is the chatter of one of the most endangered mammals in North American, the black footed ferret. 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.
The Arctic and Antarctic are the only places on Earth where permafrost is found. some scientists believe this frozen ground is disappearing because of climate change. Ted Schuur is an ecosystem ecologist with the Center for Ecosystems Science and Society.
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.
A program at Northern Arizona University encourages students to use their own life experiences to develop community projects. Students with NAU’s Campus and Community Based Action Research Teams are digging deep within themselves to recall significant events, even painful ones like domestic violence or abuse, and use them to connect with the community. Lauren Berutich is the program coordinator.
