Skeleton involves a person riding a small sled down a frozen track while lying face down. The sport is a more intense form of luge because skeleton competitors leap onto the sled and slide downhill head first. Skeleton athletes can reach up to 80 mph on straightaways, causing forces up to 5g, so the helmet is a critical component for attitude as well as safety.

It’s a tradition that dates back hundreds of years, where two stallions fight over a female to ring the Chinese new year. And when it’s the Year of the Horse, the fights are considered to be even more significant. They’re held in small villages across southern China and have been condemned by animal rights groups, including Hong-Kong based Animals Asia. But those who participate in the events defend the fights and insist they take care of the animals.

Vadim Voitekhovitch was born in a small town of Mozyr, Belarus. He spent most of his life Belarus and he graduated from Bobruisk Art College. From 2004 he lives and works in Germany.

They say the great photographers are out of bed before sunrise and always late for dinner. Photographer Alex Robciuc does just that; waking at 5 AM to capture the gorgeous morning light spilling over a small county in Transylvania, Romania. This dedication to early rising and sticking around for the "perfect light" has offered Alex some seriously beautiful landscape images.

“The fennec fox is a small nocturnal fox found in the Sahara of North Africa. Its most distinctive feature is unusually large ears. The name “fennec” comes from the Arabic word for fox, and the species name zerda has a Greek origin that refers to its habitat. The fennec is the smallest species of canid in the world; coat, ears and kidney functions have adapted to a high-temperature, low-water, desert environment. In addition, its hearing is sensitive enough to hear prey moving underground”. – Wikipedia

Fighters of the Free Syrian Army fire an anti-aircraft weapon in the rebel-held Mashhad area in southeastern Aleppo, on December 12, 2016, as they battle Syrian government forces during an operation to retake the embattled city. The crucial battle for Aleppo entered its “final phase” after Syrian rebels retreated into a small pocket of their former bastion in the face of new army advances. The retreat leaves opposition fighters confined to just a handful of neighbourhoods in southeast Aleppo, the largest of them Sukkari and Mashhad. (Photo by AFP Photo/Stringer)
