Future TV Displays

It's 80 years since John Logie Baird demonstrated a prototype 'televisor' to members of the Royal Institution.

What kinds of displays are being demonstrated now that might be popular in future? And how will TV displays change? Will they be brighter, bendier and more energy efficient? 

John Ive from Sony and Professor Donal Bradley of Imperial College join Quentin Cooper to look at the past and future of TV display screens.

Limestone Decay

Oxford's Magdalen College was cleaned in the 1970s, but the fresh stone is already showing signs of decay. So scientists from Oxford, Belfast and City Universities are trying to find out how and why.  

Dr Heather Viles and Professor Bernie Smith are experts in weathering and they explain how some of our heritage is under threat from catastrophic limestone decay.
