A vivid journey into the mysterious subterranean world of mycelium and its fruit— the mushroom. A story that begins 3.5 billion years ago, fungi makes the soil that supports life, connecting vast systems of roots from plants and trees all over the planet, like an underground Internet.

Some 240,000 women over 55 are at risk of homelessness In Australia – a figure both surprising (owing to this demographic being less likely to speak up about their difficulties) and shocking, given this country’s wealth. Under Cover introduces us to 10 of these people, including a survivor of domestic violence, a former advertising executive, a self-confessed loner and a displaced immigrant, for whom security and shelter are constant unknowns and who, until now, have suffered in silence.

Probably no other sea animal has captured our affection and attention like the dolphin. Its intelligence and athleticism has fascinated observers for years. Dolphins seem to exhibit a friendly willingness to co-operate with humans...something very rare in the wild animal kingdom.

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 We're even witnessing jellyfish populations appearing in more and more regions where fish have been replaced by them, such as off the coast of Namibia, in the Black Sea, in the Sea of Japan and in certain areas of the Baltic Sea.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?
