Artificial intelligence can pick out the words we're typing from analysis of our brainwaves. Could it give a voice to those who can't speak because of brain injury or illness ? We interview an expert leading the research.

Also on this week's edition of Tech Life, will AI and 3D printing revolutionise the shoe business ? And the hot and cold solution to keep fish fresh in Kenya.
