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.

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.
