Finalists named for $10m Star Trek 'tricorder' X Prize

Ten finalists have been chosen in a $10m (£6m) competition to develop a real-life "tricorder" - the medical scanner used in the Star Trek series.

The Qualcomm Tricorder X Prize, launched last year, challenges anyone to develop a wireless device capable of detecting a range of diseases.
The technology employs sensors and imaging to measure vital signs and diagnose conditions non-invasively.
X Prize officials said the technology was now "fact, not science fiction".
The 10 finalists come from a range of backgrounds, including universities, medical device manufacturers and tech start-ups.
One research team is backed by Nasa and the Bill Gates Foundation, while another is made up of engineering students at Johns Hopkins University in the US.
They now have until the middle of next year to develop workable prototypes of their devices in the hope of winning the prize.
