Material World 'Smart materials' have revolutionised engineering in recent decades and are so called because they interact with the environment by responding to changes in temperature or moisture. Such materials can return to their original shape after exposure to extreme conditions.
Quinten Cooper looks at the development of this technology, and its uses, which range from construction to surgical applications. Nice.

Five hundred years ago, however, it saw 25,000 soldiers fight one of the most crucial battles in the War Of The Roses. Neil Oliver and Tony Pollard attempt to unearth new secrets from the famous battle. Those fascinated by trans Pennine rivalries may like to consider the importance of Leeds United's 1-0 win over Manchester United last week. Glory, glory Leeds United (that's enough football - ed).
