What happens when a blacksmith meets a metallurgist? This week we  explore what's happening at the molecular scale when the smithy works a  piece of iron, we meet the superalloys that survive temperatures way  above their melting points inside jet engines, and at the Rolls Royce  precision casting facility we discover how precision plane engine parts  can be cast from a single metal crystal. Also, in the news this week,  how the blind brain has a built-in sonar, an attractive new magnetic  material turned on by a current, and a new technique to detect  troublespots brewing inside arteries. Plus, Kitchen Metallurgy - an  experiment to show how you can manipulate metal molecules for yourself!
