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.
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.
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.
Some scientists predict the Southwest will continue on its warming trend. NAU biology professor Tom Whitham says the rise in temperatures is happening so fast - 3 degrees in the last 60 years - that many plants are not able to adapt and survive.
Bacteria make up most of life on Earth. It's life we can't see. Some bacteria thrive in such extreme environments as the boiling water of the hot springs in Yellowstone National Park, or in the driest place on Earth - the Atacama Desert of northern Chile. But, according to Greg Caporaso in the Center of Microbial Genetics and Genomics at NAU, the most extreme environment for life is inside the human body.
