The DNA Switch

   2019    Medicine    HD
Destiny is beyond our control, our fate already set, perhaps from the onset of disease or being born with a special ability. You may think our lives are determined by the genes we're born with, but that is not the case. In the non-coding 98% of our DNA, we have countless switches to promote or suppress the physiological reactions of our bodies. Interestingly, we can change the states of these switches through our own efforts and even can affect the DNA conditions of our offspring before their birth.

What Is Out There

   2010    History
An informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society's historical path. The Story Of Science tells the forces that came together to create scientific knowledge; the practical business of making instruments and machines; the great forces of history – revolutions, voyages of discovery and artistic movements – and the dogged determination of scientists and experimenters. This is the story of how scientific ideas shaped the modern world and how science made history. Michael Mosley begins the first episode with the story of one of the great upheavals in human history - how we came to understand that our planet was not at the centre of everything in the cosmos, but just one of billions of bodies in a vast and expanding universe. He reveals the critical role of medieval astrologers in changing our view of the heavens, and the surprising connections to the upheavals of the Renaissance, the growth of coffee shops and Californian oil and railway barons. Michael shows how important the practical skills of craftsmen have been to this story and finds out how Galileo made his telescope to peer at the heavens and by doing so helped change our view of the universe forever.

Dragons of the Dry

   2008    Nature
About 340 million years ago a brand new family of animals was evolving in the primeval swamps. They were to go one step further than the amphibians who had emerged onto dry and before them. For they would eventually completely cut their ties with water. They were the ancestors of todays lizards. They evolved scaly impermeable skins and moved up into the forests. They diversified into a multitude of different shapes and sizes. They developed signalling systems to communicate with one another. And they squabbled as animals do. For food they hunted insects that were already well established on the land in great numbers. And here without returning to water they produced their families. They powered their bodies not only with food but with the heat that they drew directly from the sun.
As they diversified so they spread into the harshest of the lands habitats. The baking waterless deserts which eventually they would come to dominate. Discover jacky lizards that wave, wrestling beaded lizards and the the world's smallest chameleon, which is no bigger than his thumbnail, and the biggest lizard in Australia.

Flowering

   1995    Nature
The third episode is devoted to the ways in which plants reproduce. Pollen and a stigma are the two components needed for fertilisation. Most plants carry both these within their flowers and rely on animals to transport the pollen from one to the stigma of another. To do this, they attract their couriers with colour, scent and nectar. It isn't just birds that help pollination: some mammals and reptiles also do so. However, it is mostly insects that are recruited to carry out the task. To ensure that pollen is not wasted by being delivered to the wrong flower, some species of plant have developed exclusive relationships with their visitors, and the gentian and its attendant carpenter bees is one example. Since pollen can be expensive to produce in terms of calories, some plants, such as orchids, ration it by means of pollinia and a strategically placed landing platform. Other orchids offer no reward for pollination, but instead mislead their guests by mimicking their markings and aroma, thus enticing males to 'mate' with them (Pseudocopulation). The most extreme fertilisation method is one of imprisonment, and one plant that uses it is the dead horse arum. It is often found near gull colonies, and mimics the appearance and smell of rotting flesh. Blow-flies are attracted to it, and are forced to stay the night before being allowed to depart in the morning, laden with pollen. Finally, Attenborough introduces the world's largest inflorescence: that of the titan arum.

Earth: Venus Evil Twin

   2015    Science
There is a hellish planet in our solar system; covered in thick dense clouds and roasted by colossal temperatures. It will be inevitable that the Earth will someday not only be like Venus, but actually put it to shame. A billion years from now, Earth's oceans will boil off, triggering a runaway greenhouse effect, and the temperature will be so high, its all surface will melt. In the distance future, Earth could be the evil twin of Venus. To understand how our world will be destroyed we need to look at what happened to Venus.
