Just a week before Rio de Janeiro hosts South America's first Olympics, city residents expressed mixed feelings about the cost and security of the Games, while holding out hope they will bring joy to a nation facing economic and political crises. The conflicted thoughts mirror a recent survey by the Datafolha polling group showing that half of Brazilians were opposed to holding the Games, while 63 percent think the costs of hosting the event will outweigh benefits.

Everyone wants to get something for nothing - whether it's a lucky upgrade that means you can turn left when you get on a plane instead or heading off into the economy seats, or even getting a few extra features thrown in for free when you buy a new car.

As some of the sharpest businesses around, no-one understands this quite as well as casinos and that's why they all have a system that they call comps. It's short for "complimentary offers" and these are special treats specially designed to reward you for your loyalty to the casino in question. They're basically bonuses.

Globe-trotting photographer couple Peter Sedlacik and Zuzu Galova have found a fun way to document their travels around the world. Wherever they are, they face each other, frame up a great composition, and take a picture of each other… taking a picture of each other. Thus was born the photo series/project “Lens Between Us”, which is quickly scooping up followers on Tumblr, Facebook and Instagram alike. The resulting diptychs are creative, well-composed, and whimsical in the best way. A tribute to how their focus is always on each other, the images are part travel photography, part portraiture, and challenging to boot since each shot requires that they figure out not one, but two compositions.

Will Burrard-Lucas takes a photo while a Meerkat perches on his lens on January 2014 in Makgadikgadi, Botswana. These adorable Meerkats used a photographer as a look out post before trying their hand at taking pictures. The beautiful images were caught by wildlife photographer Will Burrard-Lucas after he spent six days with the quirky new families in the Makgadikgadi region of Botswana. Will has photographed Meerkats in the past and was delighted when he realised he would be shooting new arrivals. (Photo by Will Burrard-Lucas/Barcroft Media)
