Iraq's second largest city, Mosul, is locked under the rule of extremists from the Islamic State group trying to purge it of everything they see as contradicting their stark vision of Islam. A trove of photographs now housed at the Library of Congress offers a glimpse of a different Mosul – before wars, insurgency, sectarian strife and now radicals' rule. The scenes were taken in the autumn of 1932 by staff from the American Colony Photo Department during a visit to Iraq at the end of the British mandate. (Photo by AP Photo)

“This is the terrifying moment a diver came head to head with a shark as it swims inches away snatching a bite for dinner. The close encounter, captured off Bimini Island in the Bahamas, shows the hammerhead approaching diver Eli Martinez who bravely stands his ground as the giant beast approaches. Eli, free diving outside of a protective cage, carefully handled the sea creature despite its menacing razor-sharp teeth – but admitted they are extremely shy and need a lot of work to allow divers close to them. After multiple trips and hours of diving nearby they finally got used to Eli in January this year – hammerheads regularly visit these waters during the winter season”. – Caters News.

Cycling jerseys, part of a collection belonging to French cycling fan Gerald, hang from a line during the 4th stage of the Tour de France cycling race from Seraing in Belgium to Cambrai in France, July 7, 2015. Photographing the Tour de France cycling race comes with highs and lows: the buzz from capturing just the right image, the tedium of long journeys, the painstaking set-up of equipment, the breath-taking scenery. Reuters photographers have worked not only to capture the thrills and spills on the roads and mountain passes. They have also shot a set of pictures showing their own quirky view from behind the scenes as they travelled through the Netherlands, Belgium and France. (Photo by Eric Gaillard/Reuters)

In a simpler time all a child or an adult needed to enjoy the outdoors was a ball and a stick. Or maybe an old tire tied to a high branch to fashion a swing. And the only instruction given to children was to “be home before dark”. Now there are iPads and computers and television screens and shrinking safe public spaces. But despite the distractions and limitations of space, these images show the charm of kicking a ball or skipping rope endures. Sometimes with modifications as a nod to changing times.

Have you ever been interested in the sign language? Surely you’ve always wanted to learn the art of sending a message using just your hands. To help people achieve this goal, Alex Solis has taken a photo of a hand showing each letter of the alphabet. However, this has been done many times before, which is why Alex decided to make each of the photos more interesting by placing little drawn animals and creatures onto each photo. Thanks to these cute little drawings the pictures become very endearing and memorable. All the little creatures blend in seamlessly into the pictures thanks to their well-chosen poses. This project, created by Alex Solis, is very unique and useful, allowing anyone to quickly remember all the listed hand gestures. (Photo by Alex Solis)
