Secrets of the Seven Earths

   2018    Science    HD
We are living in a new golden age of exploration. Planet hunters are searching far beyond our solar system and they are actually finding new worlds orbiting other suns. Thousands of these alien worlds have already been found, but this is the story of perhaps the greatest discovery yet, a star 40 light-years away with seven Earth-sized planets: Trappist-1.
This new discovery of seven alien Earth-like planets in a faraway solar system is a major milestone in our hunt for extraterrestrial life, and experts investigate the secrets of Trappist -1's mysterious worlds to reveal if we're truly alone in the universe.

T Rex Timeline

   2019    Science    HD
The Tyrannosaurus Rex is known as the king of the dinosaurs, but how did its reign begin? Meet Moros Intrepidus, a 180 lb., deer-sized ancestor to the T-Rex. Learn how the latest in palaeontology can now link this small dinosaur to the 19,000-pound Scotty, the largest T-Rex ever discovered.
We're filling in gaps in the history of well-known dinosaurs and we're finding specimens of even the most famous dinosaur that are telling us new things about their biology, about their growth, about their size, that we didn't know before. We are nowhere at the end of learning about dinosaurs and in generations to come, we will be knowing things about the lives of these ancient creatures that would probably blow our minds.

The Cognitive Tradeoff Hypothesis

   2019    Science
Join us on a journey into the mysterious depths of the human psyche as we investigate the strange and surprising terrain of the Mind Field.
Chimps and Humans can be traced biologically back to a common ancestor. The Cognitive Tradeoff Hypothesis theorizes about the two different paths of development - particularly cognitive development - that occurred in these two species after the split. Chimps stayed in the trees and developed some extraordinary cognitive capabilities which are shown by the research work of Japanese scientists, while humans came down into the savanna and developed social capabilities and language.
The hypothesis is that humans 'traded' some aspects of cognitive capabilities by re-purposing areas of the brain that had evolved in the context of other uses. Those capabilities are kept in chimps and are far surpassing that of normal humans. This is shown by the research work of scientists at the Primate Research Center connected with Kyoto University.

Life: Insects

   2009    Nature
There are 200 million insects for each of us. They are the most successful animal group ever. Their key is an armoured covering that takes on almost any shape. Darwin's stag beetle fights in the tree tops with huge curved jaws. The camera flies with millions of monarch butterflies which migrate 2000 miles, navigating by the sun. Super slow motion shows a bombardier beetle firing boiling liquid at enemies through a rotating nozzle. A honey bee army stings a raiding bear into submission. Grass cutter ants march like a Roman army, harvesting grass they cannot actually eat. They cultivate a fungus that breaks the grass down for them. Their giant colony is the closest thing in nature to the complexity of a human city.

Life: Plants

   2009    Nature
Plants' solutions to life's challenges are as ingenious and manipulative as any animal's. Innovative time-lapse photography opens up a parallel world where plants act like fly-paper, or spring-loaded traps, to catch insects. Vines develop suckers and claws to haul themselves into the rainforest canopy. Every peculiar shape proves to have a clever purpose. The dragon's blood tree is like an upturned umbrella to capture mist and shade its roots. The seed of a Bornean tree has wings so aerodynamic they inspired the design of early gliders. The barrel-shaped desert rose is full of water. The heliconia plant even enslaves a humming bird and turns it into an addict for its nectar.

Mighty Amazon

   2005    Nature
A look at the unique habitat which is formed every year when the Amazon floods an area of forest the size of England. It creates a world that is home to turtles, caiman and giant otters, and where fish fly through the air and dolphins hunt amongst the tree tops.
