Tech 24

One heart, one tree: An app that bridges tech and the environment

In this edition, we pay tribute to John Nash's work in the fields of economics and mathematics. Also, we explore a new app that allows you to plant a tree anywhere in the world using your heartbeat, called "One Heart, One Tree". And in Test 24 we take a look at a bike made partly by a 3D printer and with built-in direction assistance.
