Putting a new spin on current research

Physicists in the USA and at the London Centre for Nanotechnology have found a way to extend the quantum lifetime of electrons by more than 5,000 per cent, as reported in this week's Physical Review Letters . Electrons exhibit a property called 'spin' and work like tiny magnets which can point up...
