Cities are growing at a faster rate than any other habitat on Earth. They may seem an unlikely place for animals to thrive, but they can be a world of surprising opportunity. Leopards prowl the streets of Mumbai, peregrine falcons hunt amongst New York's skyscrapers, and a million starlings perform spectacular aerial dances over Rome. In Jodhpur, langurs are revered as religious deities and in Harar, locals live in harmony with wild hyenas. Many animals, however, struggle to cope in the urban jungle. As the architects of this environment, can humans choose to build cities that are homes for both them and wildlife?

Raging Teens follows a group of young boys and girls throughout their teenage years and captures the changes that the body undergoes through puberty. Its main focus, however, is on Beatrice and the changes she undergoes such as shopping, growing breasts, pubic hairs and her first period (her mother bought her some Chocolate Éclairs to help celebrate which must be a British thing). The boy's side covers testosterone and what changes it spurs in a lad's body such as facial hair, their voice cracking at the wrong time, and parts of the body that have until now lain dormant. You also learn that a pubic hair only grows for 6 months, which keeps it short, and is actually flat oval and not round which is why they curl.

The unearthing of a gruesome grave filled with thousands of skeletons at the beach of Kamakura in Japan could be about to unlock the true extent of the merciless violence and mystery surrounding the true origins of one of the most feared and revered warriors of all time: the Samurai.
In the Middle Ages, Kamakura was the capital of Japan. The 'Shogun', a kind of aristocratic military dictator, ruled here. This shogunate ended in 1333 with the Battle of Kamakura. A drastic event in Japanese history, because this resulted in not only political, but also social, philosophical and technical innovations. The remains of the samurai warriors who fell near Kamakura now provide scientists with detailed insights into the time of the Kamakura shogunate and the bloody conflict between the shogun and the emperor.
The chilling burial ground dates back to 1333. Kamakura was one of the most heavily fortified regions of Japan. When the Emperor became angered by the growing powers of the ruling Hojo family, he sought to retake control of the region, setting the stage for a war that would change the shape of the nation. Among over 4000 sets of remains, six have a unique story to tell: the husband and wife involved in a sword fight to the death; the warrior monk; a peasant boy soldier; and members of the ruling Hojo family, captured and decapitated, with their heads displayed as trophies of victory. These remains reveal the secrets of the Samurai, their ferocious fighting skills and their merciless killing techniques.
