Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and 'big data,' the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, 'Prediction by the Numbers' explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don't understand how they arrive at them? And how far ahead can we really forecast?

Could scientists recreate Hollywood's Jurassic Park using 100-million-year-old dinosaur DNA? Director Steven Spielberg, author Michael Crichton, actor Jeff Goldblum, and a host of scientific experts answer this compelling question in the award-winning Nova documentary, The Real Jurassic Park. Behind-the-scenes clips, interviews, and demonstrations with leading paleontologists investigate the viability of reviving the extinct species. All phases of logistics are addressed, including extracting prehistoric insect DNA, creating embryos for placement in host eggs, and more. The scientific analysis of the process leads to the examination of the ethics of recreating a vanished life form.

David Attenborough brings to life, in unprecedented detail, the last days of the dinosaurs. Palaeontologist Robert DePalma has made an incredible discovery in a prehistoric graveyard: fossilised creatures, astonishingly well preserved, that could help change our understanding of the last days of the dinosaurs. Evidence from his site records the day when an asteroid bigger than Mount Everest devastated our planet and caused the extinction of the dinosaurs. Based on brand new evidence, witness the catastrophic events of that day play out minute by minute.
