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.

As we get ready to celebrate Valentine's Day, Northern Arizona University ecology professor Nancy Collins Johnson reminds us that we can learn a lot about relationships from nature. Collins is a soils expert who studies mycorrhizal symbiosis - or, healthy relationships between fungi and the roots of plants.
The West is experiencing one of the driest winter stretches on record, and that’s got forest ecologists concerned about what these drought conditions will mean for fire season. Dr. Wally Covington is the executive director of the Ecological Restoration Institute at Northern Arizona University.
A Northern Arizona University regents’ biology professor is studying how the speed with which frogs catch insects can improve the mechanics of artificial limbs for humans. Kiisa Nishikawa has discovered the connection is a protein called titin. It essentially enables muscles to “think,” reacting in milliseconds, rather than waiting for a signal from the brain.
Step into Robert Kellar's physiology and anatomy class at NAU and you'll learn how the human body works. But, step into his lab an you'll learn how to grow human skin. Dr. Kellar can teach plants how to manufacture human protein.
It's estimated that by the new year, more than 60 million Americans will be using iPads. NAU geologist Lisa Skinner is already using them in the field with her students as a geologist time machine of sorts.
