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.

Brain Food: Hydrologic Systems And Forest Restoration

Many scientists say intense wildfires, like the Slide Fire in Oak Creek Canyon, underscore the urgency for forest restoration. Hydrogeologist Abe Springer studies how forest treatments, like thinning and prescribed burns, are impacting natural water systems. He say 80-85 percent of precipitation evaporates or transpires in northern Arizona's over crowded forests. Most of the rest runs off with very little left to recharge the aquifers.

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.
