Small transportation boats, known as bumboats, leave trails of light as they travel across Marina Bay past the skyline of Singapore in this photo taken in 2004. Singapore holds a Jubilee weekend from 7 to 10 August to celebrate the 50th anniversary of its independence. Fifty years ago, hundreds of small boats lined the Singapore river in the city centre. Today, most small boats are gone, except a handful of neon-lit tourist ferries. Maritime trade is still the backbone of the city-state but after decades of rapid growth Singapore, which at less than half the size of London is among the world’s most densely populated nations, is also a popular tourist destination and a thriving global financial hub.

Water way to go. These incredible images show the moment two brave adventurers decided to body board down Europes longest glacier. Seen carving their way through the icy rivers of the Aletsch Glacier in Switzerland, the pair are seen risking their lives for an adrenalin rush of a whole new kind. Pictured mounted on their body boards as part of a sport known as hydrospeeding, the daredevils risked being carried away by strong currents and even drowning in hidden crevices to complete the winding seven mile journey. But if that wasnt dangerous enough, the duo also ran the risk of being overwhelmed by collapsing glacial lakes that could be released into the river at any moment. (Photo by David Carlier/Caters News)
