Humpback Whale

   2006    Nature
Few sounds are more beautiful or moving than the underwater songs of the humpback whale. Male whales compete with their songs, which often last for 10 minutes at a time, and can be repeated for hours on end. Whales separated by thousands of miles of sea will sing almost identical songs. Researchers have found that the songs change throughout the breeding months, following a mysterious pattern repeated across the waves. Whales also use sound to hunt. To catch herring, humpback whales release a stream of bubbles to form a shimmering, circular fishing net. Emitting a repetitive loud scream, they scare the fish into a tight ball, then lunge out of the water to swallow the shoal whole. Now it seems that the long-held image of the gentle giant must change to one of a ferocious and opportunistic hunter.

Hunt for Alien Evidence

   2019    Science
In the third episode, the discovery of extraterrestrial life might face an impossible challenge: the physics of the universe itself; but using cutting-edge tech, experts might be on the verge of a groundbreaking find -- and the evidence could already be in hand.

Hunt for the Mars Aliens

   2020    Technology    HD
NASA's brand-new Mars rover is on the hunt for alien life, and with the help of cutting-edge engineering, scientists embark on a search for fossilized remains, which might prove the Red Planet was once home to a vast ocean and extraterrestrial life. Perseverance carries seven scientific instruments to study the Martian surface at Jezero crater. It carries several cameras and two microphones. The rover is accompanied by the helicopter Ingenuity, which will help Perseverance to scout for locations to study.

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.

Hunting for Earth Twin

   2020    Science
In just one generation, our ability to search for planets beyond our solar system has transformed. With modern techniques and telescopes, planetary scientists have found thousands of exoplanets in our universe, and many of them have the perfect conditions for life. Are we about to find Earth’s twin?

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.
