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.
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.
Nadine Barlow studies impact craters throughout the solar system. This professor of physics and astronomy at Northern Arizona University calls these craters nature’s drills because they tell us what’s buried beneath the surface.
When a bird flaps its wings or a seal dives into the ocean, it’s generating energy. Michael Shafer, an assistant professor in mechanical engineering at Northern Arizona University, says it’s possible to harvest the energy that an animal produces and use it to power transmitters that collect information for biologists.
Astronaut Mark Kelly says New York’s Times Square is the brightest place on Earth when looking down from space. After that, the next brightest is the Strip in Las Vegas. What may not be readily seen from space is Flagstaff, the first International Dark Sky City. That’s a designation he and his wife, former congresswoman Gabby Giffords, fully support. Kelly recently spoke on the campus of Northern Arizona University.
A machine that helped astronauts get used to what it feels like to walk in space is now being used at Northern Arizona University. Physical Therapy Professor Dirk de Heer says the Alter G Anti-Gravity Treadmill teaches students about biomechanics.
In the near future, so-called smart materials may eliminate the need for batteries in hybrid cars and in solar panels. Cornell Ciocanel is a mechanical engineer at Northern Arizona University. He’s developing a new smart material that’s strong enough to be used in the body of a car and also stores electricity like a battery.
A Northern Arizona University professor emeritus says he’s never seen anything like a recent find in the Utah desert. This, despite 25 years spent studying rock art at thousands of sites. Retired ethnolinguist Ekkehart Malotki is researching what could be the oldest known realistic engravings of Columbian mammoths in the Western Hemisphere: petroglyphs from the Ice Age near the San Juan River.
NASA wants to catch an asteroid, place it into orbit around the Earth, and send astronauts to retrieve pieces of it for scientific study. The agency just needs the right asteroid. NASA has asked Northern Arizona University astronomer David Trilling, one of the world’s foremost asteroid experts, to find it — a task much easier said than done.
