imageSewers could have bomb-sniffing sensors installed

Hidden beneath the streets of Stockholm, the city's sewage plant is working at full throttle.

As we head into one of the tunnels, the stench is overpowering: through here, the waste of 700,000 people flows.

But sewer systems have been earmarked for a new use: the fight against terrorism is moving underground.

imageIn downtown Denver, a sold-out crowd of 150 would-be cannabis entrepreneurs listened to pitches

It is an all-too-familiar scene: a beautiful autumn day dawns outdoors and a group of pale coders are hard at work inside a downtown bar in Denver, Colorado, which has been transformed into the home base of a hackathon.


The only difference? The people smoking a "bong" in the corner.

This is not an anachronism, but rather an obvious feature of what event organisers MassRoots have...

"Boots on the ground" is shorthand for combat troops deployed in a foreign country. Barack Obama and David Cameron have both used it - it's a phrase that is constantly cropping up in the news. But where did it come from?

Infantry have been stomping in boots through mud and sand for centuries. Back in World War One "boot" was used as an alternative to "soldier", and a soldier's introduction to service was in "boot camp". But the expression "boots on the...

imageOnly eight of the accused appeared in court in Antwerp

Forty-six people have gone on trial in Antwerp on charges of belonging to a group that sent jihadists to Syria, the largest case of its kind in Belgium.

imageUkrainian troops have been battling pro-Russian rebels across the east of the country

Seven Ukrainian soldiers are said to have died in a clash with pro-Russian rebels near Donetsk airport - in what would be the deadliest single incident for the military since a truce deal.

A tank shell hit the vehicle carrying the troops, an official said.

Three civilians were reportedly killed in other incidents.

Ukrainian activists earlier toppled a statue of Lenin in the eastern city of Kharkiv - a move likely to be seen as a provocation by pro-Russians.

The strike will last four hours, but the RCM said midwives will still be there for women giving birth.

imageThree different versions of the painting were produced

A French scientist has revealed a major new discovery about one of Leonardo da Vinci's most famous paintings, shedding new light on his techniques.

Engineer Pascal Cotte has spent three years using reflective light technology to analyse The Lady with an Ermine.

Until now, it was thought the 500-year-old painting had always included the ceremonial animal.

Mr Cotte has shown the artist painted one portrait without the ermine and two with different versions of the fur.

Visitors to this year's Turner Prize 2014 exhibition will find themselves spending much of their time watching films in semi-darkness.

The show, unveiled at Tate Britain on Monday, features several film works - and slide shows projected onto walls.

This year's artist nominees are Duncan Campbell, Ciara Phillips, James Richards and Tris Vonna-Michell.

Between them, they employ audio, video, craft and design - but there is no use of traditional painting or sculpture.
