Some are in it just for the money, others to help buy a meal. Then there are those who trade for fun or to spend time among friends. Millions of investors – pensioners, security guards, high-school students – dominate China's stock markets, conducting about 80 percent of all trades. Retirees gather in brokerage houses dotted around China also to enjoy some company and savour the air conditioning on hot days. Some start as young as 13, trading from home with an eye on future careers in finance. Winning isn't guaranteed. This year, among the most turbulent in China's financial history, its stock markets more than doubled in the six months to May, only to crash amid concerns that growth in the country, which makes everything from cars to steel, is slowing faster than previously thought.

Berlin-based artist Sebastian Bieniek unfolds the story of a two-faced female in his series of photographs “doublefaced”. Using an eye pencil and lipstick, bieniek simply draws an image of a face onto the side of skin. The sketch includes only one eye: carefully placed hair hides the rest of the face from view, revealing one, moving eye of the model. Blue, brown, awake, and sleeping variations create portraits with unique expressions and an illustrative sensibility. The 22 photographs of the hybrid girl expose her daily routine – drinking coffee, traveling on the train, taking a shower, and smoking cigarettes – capturing the daily life of a female with two faces.

The number of soldiers on both sides of WWII that were killed or went missing is just staggering. Now, the mystery surrounding one RAF pilot and what happened to him and his plane has been solved after 70 years. RAF flight Sergeant Dennis Copping climbed into his Kittyhawk P-40 aircraft in June 1942 to fly the plane to another airbase for repairs. He was never seen or heard from again.

Joseph Szabo was a frustrated high-school teacher in need of inspiration – so he started photographing his students, and captured all the angst and excitement of being caught between childhood and adulthood.

A statue by Italian artist Maurizio Cattelan of Adolf Hitler praying on his knees in Warsaw, Poland, on Friday Dec. 28, 2012.
