Two scientists have shared this year's Nobel Prize for Physics for their "groundbreaking" work on a material with amazing properties.
Andrei Geim and Konstantin Novoselov, both at Manchester University, UK, took the prize for research on graphene.
Graphene is a flat sheet of carbon just one atom thick; it is almost completely transparent, but also extremely strong and a good conductor of electricity.
Its unique properties mean it could have a wide array of practical uses.
The breakthrough could lead to the manufacture of innovative electronics, including faster computers, according to the Nobel Prize Foundation.
"I'm fine, I slept well. I didn't expect the Nobel Prize this year," said Dr Geim.
The Nobels are valued at 10m Swedish Kronor (£900,000; 1m euros; $1.5m).
Dr Geim said his plans for the day would not change - he said he would go back to work and carry on with his research papers.
He added that he would "muddle on as before".
The researchers were both born in Russia, but were based at the University of Manchester when they published their groundbreaking research paper on graphene in 2004.
