It's British Science Week, and in this week's show David meets Camilla Easter, CEO of Oxford Medical Products, who has a sustainable and affordable solution for obesity. How are attitudes changing (or need to change) towards weight-loss?

Also on the show we're crossing the Atlantic to speak to Ross McGraw, VP Marketing at Hammerhead. We're learn how a group of obsessives are building a brand that cyclists can get really excited about.

We have launched a film exploring MedTech. Head to www.nashsquared.com/techflix to explore how technology is helping to drive better patient outcomes with Philips and Ochre Bio.
