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.

Biologist Egbert Schwartz has developed a technique to identify whether micro-organisms can grow in places where no other signs of life can be found, like the rocky, icy region of Antarctica's McMurdo Dry Valleys.

As highways, cities, canals and railroads continue to be built across the West, some natural landscapes are becoming fragmented into patches, too small to support populations of certain animals.
