Hunt for the Oldest DNA

   2024    Science    HD
For decades, scientists have sought to unlock the secrets of ancient DNA, a fragile genetic blueprint that rarely survives millions of years. Danish biologist Eske Willerslev had a groundbreaking idea: instead of searching for DNA in fossils or ancient tissues, he looked to frozen sediment. Initially dismissed as impossible, his work led to the recovery of genetic traces from over two million years ago, revealing lush ecosystems that existed before the Ice Age. These discoveries offer unprecedented insights into long-extinct species that thrived in warm, verdant Arctic landscapes.
Willerslev’s perseverance revolutionized DNA research, enabling scientists to reconstruct vanished ecosystems and uncover the genetic secrets of ancient worlds. By examining the DNA of past climates, researchers are paving the way to better understand Earth's deep history and adapt to current environmental challenges. This landmark breakthrough demonstrates that ancient DNA acts as a "time machine," allowing humanity to explore its distant past and draw lessons for the future.

Humboldt Epic Explorer

   2020    History
In 1799, the German scientist Alexander von Humboldt embarked on a perilous journey of discovery across South America. It would take him to the deepest jungle near the Orinoco and to the heights of the Andes. His aim was twofold: to conduct the first scientific survey of South America and to discover how the natural world actually works — at a time when most scientists believed that the world was created less than 6,000 years ago. He later became a leading scientific figure and champion of the abolitionist movement in the US.
This extremely visual docudrama follows Humboldt’s extraordinary path. Travelling in Humboldt’s footsteps is historian Andrea Wulf, whose book on Humboldt became a worldwide bestseller. For good reason, since Humboldt’s ideas on the planet’s fragile web of life are as important today as they were 220 years ago.

Hunting for Martian Life. The Perseverance Rover

   2020    Technology    HD
Meet Perseverance, NASA's latest rover, as it heads to Mars to answer one question: did life exist on the red planet? On the way, it will lay the foundation for human exploration of our closest neighbour.
Today, Mars is hostile to life. It's too cold for water to stay liquid on the surface, and the thin atmosphere lets through high levels of radiation, potentially sterilizing the upper part of the soil. But it wasn't always like this. Some 3.5 billion years ago or more, water was flowing on the surface. It carved channels still visible today and pooled in impact craters. A thicker carbon dioxide atmosphere would have blocked more of the harmful radiation. The Mars 2020/Perseverance rover is designed to better understand the geology of Mars and seek signs of ancient life. The mission will collect and store a set of rock and soil samples that could be returned to Earth in the future. It will also test new technology to benefit future robotic and human exploration of Mars, as the Ingenuity Helicopter.

Secrets of the Red Planet

   2025    Science    HD
Groundbreaking missions and the latest research are finally uncovering the long-hidden secrets of Mars. From ancient water flows to possible traces of life, scientists are piecing together the planet's dramatic past. As powerful new technology scans its surface and atmosphere, experts confront extraordinary questions: Did Mars once support life? And could humanity one day make the Red Planet its second home? A stunning exploration into the evolving mysteries of our nearest planetary neighbor.

Nature Microworlds: Galapagos

   2012    Nature
A visit to arguably the most famous archipelago on Earth, the Galapagos. It's home to a myriad of bizarre and unique creatures, endemic to these islands - but how did they get here and what is the key to these extraordinary islands that allows them to thrive? The programme reveals that this key holds not just the secret to life here, but also to how Darwin was able to leave with the ideas that would revolutionise biology.
