Sliced Bread

What will mobile phones be like in future? Greg Foot investigates
Greg Foot, host of the BBC Radio 4 show 'Sliced Bread', brings you 'Dough'.
Each episode explores future wonder products that might rise to success and redefine our lives.
Experts and entrepreneurs discuss the trends shaping what today's everyday technology may look like tomorrow, before a leading futurist offers their predictions on what life might be like within five, ten and fifty years.
This time we’re looking at the future of mobile phones - asking whether our handsets will shrink, stretch, roll, fold… or even disappear as new technology takes over? And will super-smart devices with AI assistants that second-guess our every move become the new normal?
Alongside Greg is the futurist, Tracey Follows, and expert guests: leading strategist in the tech industry, Chetan Sharma, innovator and creator from one of the world’s newest Mobile Phone manufacturers, “Nothing Mobile", their AI and design lead, Sélim Benayat and co-founder and CEO of Honest Mobile, Andy Aitken.

Sleep deprived parents everywhere are tempted to reach for anything that might help them get a little more sleep overnight – but can products promising to encourage babies to snooze for longer – really do that? And is there any science to back it up?
That is exactly what tired Dad-of-three Dave wanted to know – and whether there were any future implications from using these gadgets, docks, blinds and sleep bags?
New Dad Greg Foot speaks to Director of the Durham Infancy and Sleep Centre Professor Helen Ball, to find out.

Which knife is best for the kitchen and how do you keep it sharp?
After buying various knives over the years that ended up blunt, listener Susan is looking for one that will last. She's seen an array of different types and materials: Damascus steel, Japanese Gyuto knives, as well as alloys and additions that promise a sharper edge. They vary hugely in price - anything from £50 to £1,000. And if you do invest, how do you keep a knife sharp?
To cut through the marketing BS, presenter Greg Foot is joined in the studio by Mark Miodownik, Professor of Materials & Society at University College London, and Rob Haslam aka Mr Knife Guy.
