This photo series shows curvy canines and flexible felines participating in a spot of yoga. The shots feature the animals in the likes of the lotus position, balancing on two legs, and stretching in ways that would make the greatest of yoga masters proud. Photographer Dan Borris came up with the idea for the series in 2000, when he was asked by a friend to photograph her in a yoga pose while her dog bothered her. Pictured: Wally.

A tourist take a photograph of a sulphur lake in the Danakil Depression on January 23, 2017 near Dallol, Ethiopia. The depression lies 100 metres below sea level and is one of the hottest and most inhospitable places on Earth. Despite the gruelling conditions, Ethiopians continue a centuries old industry of mining salt from the ground by hand in temperatures that average 34.5 degrees centigrade but have risen to over 50 degrees.

Photographer Joana Choumali’s latest project explores body image and beauty by documenting the men building Abidjan’s clothing models. The “Awoulaba” mannequin is a customised model designed with the African ideal of beauty in mind, curvier than the stick-thin examples usually seen in the west. They first appeared in 2011, and have since become a familiar sight outside the numerous clothing shops dotted throughout Ivory Coast’s capital, Abidjan.

These images of abandoned hospitals across Italy are not for the faint-hearted. Both of the hospitals featured in the photographs are Italian asylums – known as manicomios – that were used as mental hospitals. Shut down by law in 1978, the derelict buildings are visibly overgrown and make for very eerie portraits. Photographer Thomas Windisch, 32, of Graz, Austria, said the asylums, located in top-secret spots, can get very creepy when there aren't many people there with him. Here: a hallway within an abandoned hospital. (Photo by Thomas Windisch/Caters News)
