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.
