Live trials are under way in Ghana of holoportation 3D telemedicine tech. It allows a patient in a remote location to connect to a doctor many miles away, and be examined. We speak to the lead engineer involved in the project, as well as a patient and a doctor benefiting from the portable kit.

Also on Tech Life, what happens when a country's leader decides the names of some places (or stretches of water) are about to change ? Do online maps update ? How is it decided ? Our reporter has been searching for the answers.

And what is it like working as a technology correspondent, reporting on the busy and ever-changing North America tech scene ? We chat to Lily Jamali who does exactly that for the BBC.

We are always keen to hear from you. You can email us: [email protected], or send us a text message or voice note on Whatsapp: +44 330 1230 320.
