Hagia Sophia: Istanbuls Ancient Mystery

   2015    History
Whether serving as Christian church, Islamic mosque, or secular museum, Hagia Sophia and its soaring dome have inspired reverence and awe. For 800 years, it was the largest enclosed building in the world—the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537?" As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets. Follow engineers as they build a massive 8-ton model of the building's core structure, place it on a motorized shake table, and hit it with a series of simulated quakes, pushing it collapse—a fate that the team is determined to avoid with the real building

Wild Wild Country Part Two

   2018    Culture
Ma Anand Sheela and several other followers recount their experiences of moving to the ranch and the hostility from the residents of the city of Antelope. With the help of architects, engineers, city planners and commune residents, Rajneeshees construct a town called Rajneeshpuram. The commune decides to become self-governing which would allow them to issue their own building permits and have separate law enforcement.
Locals describe their mistrust towards Bhagwan. The American press begins to affiliate Rajneeshpuram with the Jonestown Massacre and paints Bhagwan as an antichrist. The group '1000 Friends of Oregon' initiates a court case to have the buildings of Rajneeshpuram destroyed. In response, Sheela begins buying up available properties in Antelope.

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.

Ocean Deep

   2006    Nature
Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour. Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.

   2003    Science
If you're a paleontology buff, this series is for you. And the fun-loving Nigel Marvin provides a great narrative. Explore the prehistoric world in search of sea-based monsters. It focuses on life in ancient oceans during each prehistoric period. Nothing, not the carnivorous dinosaurs of the past, nor the imagined sea serpents and monsters of maritime history, nor the great white shark, salt water crocodile, killer whale and leopard seal of today can compare to the horrifying hunters of the prehistoric oceans.
