Two scientists who put the 'nano' in iPod Nano have been awarded a 2007 Nobel Prize.
Albert Fert of France and Peter Gruenberg of Germany discovered the giant magnetoresistive effect, or spintronics, simultaneously and independently in 1988.
It uses the spin of the electron to store and transport information instead of the electrical charge, meaning much more information could be kept in a smaller space than before.
The technology allowed the development of handheld devices such as iPod music players and mobile phones that function like little computers.

The two men will share the 10m Swedish crown (€1.09m) Nobel Physics prize and join the prestigious ranks of Albert Einstein, Marie Curie, and Niels Bohr.
The winner of the Nobel prize for chemistry will be announced tomorrow, followed by the literature prize on Thursday and peace on Friday.
