Â鶹ԼÅÄ

US airlines have warned that switching on new 5G mobile services could cause disruption. The Â鶹ԼÅÄ's Theo Leggett discusses the background to the problem, and its implications. Also in the programme, Spain's government is taking action to try and help young people find housing, by approving a "youth bonus" voucher system worth €250 per month to help with rent costs. Eduardo Alonso Arechaga is a member of the Spanish Youth Council, which represents young Spaniards, and gives us his reaction to the news. There's been a big rise recently in the number of young people trading on the financial markets, and many are using mobile phone apps which are designed to make the process fun. The Â鶹ԼÅÄ's Rob Young reports on the potential pitfalls involved in the so-called gamification of stock market trading. Plus, with a virtual World Economic Forum under way in Davos, Switzerland, we hear from one of 15 winners of the Social Innovators of the Year awards, Mikaela Jade, who is a former park ranger in Australia who now runs a Canberra-based company which specialises in digital skills training.

Today's edition is presented by Mike Johnson, and produced by Will Bain and Sara Parry.
