Associated Press photographer Wong Maye-E tries to get her North Korean subjects to open up as much as is possible in an authoritarian country with no tolerance for dissent and great distrust of foreigners. She has taken dozens of portraits of North Koreans over the past three years, often after breaking the ice by taking photos with an instant camera and sharing them. Her question for everyone she photographs: What is your motto? Their answers reflect both their varied lives and the government that looms incessantly over all of them.

It’s a classic tale of dictatorship gone wrong and the fight for freedom. Like in any good battle, there’s fire, albeit from firecrackers, but the ammunition in this one is – flour. It takes place in a Hemingway-esque Spanish village. The battle of “Enfarinats” in celebration of the Els Enfarinats festival, rages on on December 28, 2012 in Ibi, Spain. Citizens of Ibi annually celebrate the festival with a fight using flour, eggs and firecrackers. The battle takes place between two groups, a group of married men called “Els Enfarinats” who take the control of the village for one day pronouncing a number of ridiculous laws and fining the citizens that infringe them and a group called “La Oposicio” who try to restore order. At the end of the day the money collected from the fines is donated to charitable causes in the village. The festival has been celebrated since 1981 after the town of Ibi recovered the tradition but the origins remain unknown.

Yak near Yamdrok lake, Tibet. It is a long-haired bovinae found throughout the Himalayan region of south Central Asia, the Tibetan Plateau and as far north as Mongolia and Russia. The Tibetan economy is dominated by subsistence agriculture. Due to limited arable land, the primary occupation of the Tibetan Plateau is raising livestock, such as sheep, cattle, goats, camels, yaks, dzo, and horses. The Tibetan yak is an integral part of Tibetan life. (Photo by Dennis Jarvis)

People enjoy the fine weather on the coast at Wembury during the first ever nationwide survey to map the location of the threatened and creatures on March 24, 2011 in near Plymouth, England. Often found on the coast, and particularly in the south west of England, the number of oil beetle species found in the UK has halved in the last 100 years and the survey will help establish the whereabouts of the remaining four species and boost efforts to secure their future. The survey is being launched today by Buglife: The Invertebrate Trust and the National Trust in partnership with Natural England and Oxford University Museum of Natural History.
