Meet the jerboa, a rodent with long springy legs. About the size of a large mouse, the jerboa has two mighty back legs that can help propel it as high as 3 feet in the air. Now, scientists are studying their appendages to better understand and to manipulate the growth of human bones.

Tiny satellites called CubeSats have democratized space science; blended learning combines in-person teaching with tech; a high school student and a science corporation pave the way for easier use of ethanol as renewable energy; and a mouse-like creature with massive hind legs teaches us about the growth of human bones.
