The Origin of Life

   2024    Science    HD
The film, marking our first own production, embarks on an awe-inspiring journey, shedding light on one of science's most profound questions: How did life emerge from the non-living? With a focus on the intricate mechanisms that may have transformed simple molecules into the first microorganisms, this film explores the concept of a chemical evolution that meticulously selected increasingly complex molecules, eventually leading to the genesis of life. By delving into the pivotal role of RNA, viewers are invited to contemplate the plausibility of life spontaneously arising from the basic elements of the universe.
The documentary meticulously illustrates a potential pathway for the emergence of life, emphasizing the significance of ribozymes—RNA molecules with catalytic abilities—and their role in a prebiotic chemical evolution. The film posits a compelling argument for the natural processes that might have led to the formation of the first complex lipid vesicles, a critical step towards cellular life. By presenting a theory that bridges gaps in our understanding with scientific ingenuity, ‘The Origin of Life’ invites viewers on an intellectual adventure to discover the origins of existence itself.

The Private Life of Plants Living Together

   1995    Nature
The fifth programme explores the alliances formed between the animal and plant worlds. Attenborough dives into Australia's Great Barrier Reef and contrasts the nocturnal feeding of coral, on microscopic creatures, with its daytime diet of algae. Some acacias are protected by ants, which will defend their refuge from any predator. Besides accommodation, the guards are rewarded with nectar and, from certain species, protein for their larvae as well. Fungi feed on plants but can also provide essential nutriment to saplings (Mycorrhiza). The connection is never broken throughout a tree's life and a quarter of the sugars and starches produced in its leaves is channelled back to its fungal partners. Meanwhile, fungi that feed on dead wood leave a hollow trunk, which also benefits the tree. Orchids enjoy a similar affiliation. Lichens are the product of a relationship between fungi and a photosynthetic associate, usually algae. They are extremely slow-growing, and a graveyard is the perfect location to discover their exact longevity. Mistletoe is a hemiparasite that obtains its moisture from a host tree, while using own leaves to manufacture food. Its seeds are deposited on another by the mistletoe tyrannulet, following digestion of the fruit. The dodder (Cuscuta) is also parasitic, generally favouring nettles, and siphons its nourishment through periodic 'plugs' along its stem. The rafflesia has no stem or leaves and only emerges from its host in order to bloom — and it produces the largest single flower: one metre across.

The Private Life of Plants: Travelling

   1994    Nature
Sir David Attenborough reveals plants as they have never been seen before - on the move and dangerously devious. About the major problems of life - growing, finding food, reproduction - and the varied ways plants have evolved to solve it. Filmed from the plant's point of view, using computer animations, fibre-optics and unique time-lapse photography. The first episode looks at how plants are able to move". The bramble is an aggressive example: it advances forcefully from side to side and, once settled on its course, there is little that can stand in its way. An altogether faster species is the birdcage plant, which inhabits Californian sand dunes. When its location becomes exposed, it shifts at great speed to another one with the assistance of wind — and it is this that allows many forms of vegetation to distribute their seeds. While not strictly a plant, the spores of fungi are also spread in a similar fashion. One of the most successful (and intricate) flowers to use the wind is the dandelion, whose seeds travel with the aid of 'parachutes'. They are needed to travel miles away from their parents, who are too densely packed to allow any new arrivals. Trees have the advantage of height to send their seeds further, and the cottonwood is shown as a specialist in this regard. The humidity of the tropical rainforest creates transportation problems, and the liana-species Alsomitra macrocarpa is one plant whose seeds are aerodynamic 'gliders'. Some, such as those of the sycamore, take the form of 'helicopters', while others, such as the squirting cucumber release their seeds by 'exploding'. Water is also a widely used method of propulsion. The tropical sea bean Entada gigas has one of the biggest fruits of all plants and is dispersed by water streams. However, most plants use living couriers, whether they be dogs, humans and other primates, ants or birds, etc., and to that end, they use colour and smell to signify when they are ripe for picking.

The Propaganda Game

   2015    Culture
North Korea, formerly known as the hermit kingdom, is perhaps the largest source of instability as regards world peace. Its border is one of the most militarized in the world. The lack of impartial information, both inside and coming out of the country, is the perfect setting for a propaganda war, which will be analysed in the film through numerous examples of the surprising way in which information is manipulated, in and about North Korea. Alejandro Cao de Benos, the sole foreigner who works for the People's Republic of Korea Government, and many locals will show us their vision of the reality in North Korea. The other side of the story will be reflected through interviews to South Korean citizens, human rights advocates, diplomats, propaganda experts, etc.

The Race to Space

   2022    Technology
A new era of space is dawning where small satellites no bigger than a shoebox will be deployed not in one or twos, but in their thousands - referred to as satellite swarms. It's been described as the democratization of space. What was once the preserve of governments and superpowers is evolving into a truly global industry. The catalyst for this dramatic change is this new generation of satellites.
