'Singing atoms' win Nobel Prize for Physics

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Eric Cornell and Carl Wieman of the United States and Germany's Wolfgang Ketterle won the $1m (£680,000) prize for creating a form of matter that is extremely pure and coherent, in the same way that lasers are a pure kind of light.
"This year's Nobel laureates ... have caused atoms to 'sing in unison' – thus discovering a new state of matter," the Royal Swedish Academy of Sciences said in a statement.
Their "atom lasers" could in future draw microscopic computer circuits many times tinier than the smallest in use today, to build extremely fast, powerful and compact computers. Atom lasers could also power very accurate guidance systems that could pinpoint the position of airliners and space- craft to within a few inches.
Traditional electronics, in which electricity flies around circuits, and even photronics, which uses bursts of light, may one day be replaced by "atomtronics," using atom lasers to shunt individual atoms around circuits, said Phil Schewe, of the American Institute of Physics.
Dr Cornell said: "I'm a bit surprised but I'm thrilled [the prize] came so early ... I was looking at maybe a 20-year timescale."
