Honeybees are in crisis – but there is hope. Biologists are studying the estimated 20.000 bee species in the world to look for viable pollinators of our crops. In their quest they discover the marvellous world of bees: bees that live in flowers, invade other hives, produce perfumes – and pollinate our crops without us even realizing.

Roughly 20 miles off the coast of west Africa, sits a volcanic relic now completely blanketed in equatorial rainforest: the island of Bioko. It's home to some very rare species, including the drill -- one of the most endangered primates in the world. Join us on a jungle expedition as we uncover the secret life of these reclusive primates and track down the seasonal migration of the goby -- a plucky fish battling its way upriver past strong currents, deadly predators, and even a 100-foot waterfall, to reach the spawning grounds of its youth.

China, as we know it today, would not exist without the Han Dynasty. About two millenniums ago, its emperors ruled for over 400 years, and yet, few visible remains of this period exist above ground. Underground, however, it's a different story. Join a team of archaeologists as they enter the royal tombs of three emperors spanning the reign of the Han Dynasty. By excavating these sites, they hope to further our knowledge of their wealth, their beliefs, their quest for immortality, and how their culture and philosophy shaped modern China.
