In this issue of How It Works, we’re going to take you on a journey through the digestive system, from one end to the, err… other end! Discover how food is broken down, how nutrients eventually become part of your body, and how your brain plays a pivotal role in every stage of digestion.

Also this issue, we look at the future of racing vehicles as we look inside a Gen 2 electric race car and learn about the cutting-edge technology that drives Formula E. Discover why Africa can’t survive without lions, how crime scene investigators are able to identify criminals from the tiniest clues, how Jupiter saved the Earth, and we speak to a man who has been to the bottom of the ocean in a submersible he designed himself.
