After months of anticipation and rumour, the Interphone Study Group has published its results into the risk of brain tumours (glioma and meningioma) in relation to mobile phone use. Those results, printed in the International Journal of Epidemiology, have the following conclusions:

We've previously talked about the long-awaited Interphone study into the possible cancer risks of using mobile phones. It now looks as though the results will be published on Tuesday 18th May, although that hasn't stopped media speculation from starting early.

A new study has been launched today to investigate whether there is a link between the use of mobile phones and long-term health problems such as cancer. It's called the cohort study on mobile communications (COSMOS) and forms part of the Mobile Telecommunications and Health Research Programme, which is funded by government and industry.

COSMOS participants will be from the UK, Denmark, Sweden, Finland and the Netherlands. The study will run for 20-30 years and will follow the health of at least a quarter of a million participants aged 18-69. The UK arm of COSMOS is being led by a research team from Imperial College London.

Iain, James and Mark talk about mobile phone health concerns, Nokia's legal action against Apple, the return of the rumoured Google gPhone, open source software, an art exhibition controlled by text messages... and much more.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
