The very first episode, ever

This week's Science 360 covers a bionic leaf that mimics photosynthesis to create liquid fuel, increased flooding in the Midwest linked to climate change, and a smart Band-Aid that can sense and respond to wound conditions. For more science updates, visit Science 360 online.

What is the significance of the efficiency increase from 1% to 5% for the bionic leaf?

What are the potential future applications of the Band-Aid that researchers are developing?
