Reuters photographer Bobby Yip took a series of portraits of people taking part in the “Occupy Central” protests in Hong Kong, and asked them why they had joined the demonstrations. China rules Hong Kong under a “one country, two systems” formula that accords the territory limited democracy. Tens of thousands of mostly student protesters are demanding Beijing give them full democracy, with the freedom to nominate election candidates. The unrest is the worst in Hong Kong since China resumed its rule over the former British colony in 1997. (Photo by Carlos Barria/Reuters)

This might quite simply be the oddest skydive youll ever see – as a pair of daredevils simulate a rodeo ride as they hurtle towards earth. In the bizarre pictures, skydiver Robyn Young managed to straddle co-jumper Oliver Miller, as they plummet through the sky – and amazingly, pal Jeff Donohue caught it all on camera. The pair managed to perform the stunt before going their separate ways and pulling their parachute cords during the skydive over recibo, Puerto Rico, last month. Here: Robyn Young surfs on the back of Oliver Miller as they descend upon Arecibo, Puerto Rico. (Photo by Jeff Donohue/Caters News)

“We take rusty old junk and we put love into it”. The old Motor City has a unique style in bicycles these days: from fat wheels and fake fuel tanks to stretched cycles with powerful sound systems – and even a family-sized BBQ. “Detroit’s custom bike scene developed alongside Slow Roll, a weekly cycle ride started in 2010 by Jason Hall and Mike MacKool. Now upwards of 2,000 people turn up each Monday to cruise a different part of the city. The week I go the crowd seems evenly split between black and white, male and female, city and suburbs. It’s the most inclusive cycle event I’ve ever witnessed”. (Photo by Jason Walker/Slow Roll Monday Nights)
