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.

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.

Brain Food: The One Gene Difference

NAU biology professor Tom Whitham

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.
