´óÏó´«Ã½

US airlines have warned that switching on new 5G mobile services could cause disruption. The ´óÏó´«Ã½'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 ´óÏó´«Ã½'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.
