Don't Log Off

Alan Dein discovers the real life stories behind online profiles via Facebook and Skype. Alan locks himself away for a week to talk to people on the internet. He starts with nothing, just an online profile which says 'talk to me'. The results are intriguing, funny and often very moving.

Frontiers explores new ideas in science and meets the people behind them. There are two six-part series of Frontiers a year, in summer and winter. The programme is half an hour long.

How Dangerous

Dick and Dom explore the surprising science that can be found around us. With the help of some young volunteers, they meet scientists who show them a selection of hands-on experiments - which you can try out for yourself at home - revealing new facts about everything from remote controls to bicycle brakes.
