It's been more than 50 years since all four members of The Beatles released music, with their emotional classic'The End'. But despite just two members remaining - Sir Paul McCartney and Ringo Starr - the band is preparing for a comeback. McCartney has revealed that he is using artificial intelligence (AI) to'extricate' John Lennon's voice from an old demo to create the'final Beatles record.' While he's yet to name the song, it's likely to be a 1978 Lennon composition called Now And Then, according to the BBC. Speaking to Radio 4's Today programme, McCartney explained: 'We just finished it up and it'll be released this year.'

The lectures will examine what Russell will argue is the most profound change in human history as the world becomes increasingly reliant on super-powerful AI. Examining the impact of AI on jobs, military conflict and human behaviour, Russell will argue that our current approach to AI is wrong and that if we continue down this path, we will have less and less control over AI at the same time as it has an increasing impact on our lives. How can we ensure machines do the right thing? The lectures will suggest a way forward based on a new model for AI, one based on machines that learn about and defer to human preferences. The series of lectures will be held in four locations across the UK; Newcastle, Edinburgh, Manchester and London and will be broadcast on Radio 4 and the World Service as well as available on BBC Sounds.

Artificial Intelligence has made great advances in recent years, with computer scientists developing cars without drivers, planes without pilots and mobile phones which can double up as a personal assistant. The legal profession is proving to be rich territory in the AI field too. Joshua Rozenberg meets computer scientists at the University of Liverpool, who are using'computational argumentation' to digitally decide the results of legal cases, proving that AI can be just as discerning as a court judge.
