When you get mysteriously ill, how do you diagnose what’s up? If you’re at home, you might have a thermometer to help identify your illness, but not much else. Even your general practice doctor is limited by the tools they have to hand. To find out, you have to go to hospital – where complicated machinery is available, for blood tests, scans and more. Unfortunately, not everybody has that access.

That’s why Anita Goel of the company Nanobiosym decided to invent a ‘tricorder’ – in the same vein as the multipurpose medical tool used in Star Trek – that has the potential to transform healthcare itself.

Watch the video above to discover what it looks like, how it works – and who it will help most.
