A look at the people, history, and recovery of the mountain since the eruption in 1980.

Meet the big birds, a feathered family who have never flown a day in their lives! From ostriches to kiwis, these bizarre birds appear to be nature's greatest novelty act. How they came to be and how they continue to survive is a fascinating tale that has long captivated Sir David Attenborough. It is a story of dedicated dads, enormous eggs and a serious need for speed. And far from being the court jesters of the animal world, these flightless curiosities once nearly ruled the land.

Presenter and comic Jacob Burley hosts Bear Hunt; a stand-up show in which he explores the existence and extinction of the brown bear in the British Isles.

Jellyfish blooms are making headlines around the world. This is due to the damage they cause to tourism, fishing and our health. How can these creatures, which are over 98% water and have no shell, skeleton or brain, expand so rapidly? Although this is a normal stage in the life cycle of these gelatinous animals, we have to admit that blooms have become much more frequent and massive in recent decades. We're even witnessing jellyfish populations appearing in more and more regions where fish have been replaced by them, such as off the coast of Namibia, in the Black Sea, in the Sea of Japan and in certain areas of the Baltic Sea. What causes this? Why has the role of jellyfish in the ocean been underestimated, even though they outlived the dinosaurs? Are jellyfish on their way to dominating the oceans as they once did? What if they were to be the only ones left?

It is winter at an emergency shelter for the homeless in Lausanne. Every night at the door of this little-known basement facility the same entry ritual takes place, resulting in confrontations which can sometimes turn violent. Those on duty at the shelter have the difficult task of “triaging the poor”: the women and children first, then the men. Although the total capacity at the shelter is 100, only 50 “chosen ones” will be admitted inside and granted a warm meal and a bed. The others know it will be a long night.
