Seed Hunter is a one-hour documentary, as part of the ABC's Future Makers series, about the hunt for seeds that may help save the world from its greatest ever crisis - a global food shortage brought about by human-induced climate change. As Australia and much of the world wrestles with hotter weather and a dwindling water supply, mass starvation on a global scale is on the cards if we can't find ways to improve crop resilience. Scientists are exploring many solutions to adapt our food supply, including going back to Mother Nature herself to locate the genes that can withstand our changing climate; genes that, thanks to a high-yielding monoculture, have almost disappeared.
In the 70s, the world seemed to be falling apart. From acid rain to overpopulation and resource depletion, ecological concerns were big news. And it was at this time that climate change first became a hot political issue.
Richard Hammond returns with the second series of Engineering Connections, visiting 'down under', Towering over Sydney Harbour, the famous Opera House is one of the most recognisable and iconic buildings in the world. Richard takes a stroll along the incredible structure's roof, learns how its unique "sails" work, and discovers a bizarre engineering connection with a First World War gas mask.
Dr Aleks Krotoski continues her investigation into how the world wide web is transforming our lives. In this second film in the series, she charts how the web is forging a new brand of politics.
We all know the word "Neanderthal" to be an unflattering qualifier for some of our more uncultured and dim-witted fellow humans. But was the real Neanderthal man truly such an intellectual dunce? The Real Neanderthal Man looks at modern scientific findings that reveal quite the opposite.
Colour blindness is when people are unable to distinguish between certain colours, and the most common form of this disorder is red/green colour blindness. Paul Martin, a vision scientist from the University of Melbourne, explains what causes it and the types of colour blindness out there.
From birds and mammals to fish and frogs, lots of different animals can change their colour. Jessie Sinclair, a zoologist from the Melbourne Museum, will talk you through how and why animals can do this.
Have you ever stopped to wonder why flowers and fruits come in so many amazing colours Well Jason Goodger, a plant researcher from University of Melbourne, will take you through how and why fruits and flowers vary in so many colours.
This short BBC clip offers an excellent backgrounder to humanity's relationship with the moon.
Volcanoes and earthquakes are only part of a bigger picture. Tectonic forces also push continents around and cause mountains to be uplifted. The crust recycles itself. The lighter rocks of the continents float on the heavier rocks of the mantle.
World renowned climate scientist Michael Oppenheimer outlines the evidence for global warming.
The Moon takes a look at our closest neighbour in space. How was it viewed by our ancestors? What is its effect on the Earth and on people? Is it really made of cheese?
In this episode, Adam and Jamie tackle Sir Isaac Newton's founding principle of thermodynamics and the law of conservation of momentum. They're looking into a physics classroom urban myth. If birds in a truck take flight do they lighten the load? Meanwhile, Grant, Tory and Kari become crime scene investigators.
Brief view of different habitats to stimulate students' interest.
Using dramatic reconstructions, interviews and CGI graphics the programs reconstruct the world of the Neanderthal. Is it possible that through the interbreeding of Neanderthals and Homo sapiens, every person of European descent may have a little bit of Neanderthal in them? And that Neanderthal genes might show up in fundamental traits, like big brains and sociability, that we think of as particularly human?
Studying the Earth's atmosphere help scientists to understand the weather and long-term climate changes. Top discoveries about our planet include continental drift theories, the composition of the inner and outer cores of the Earth and cosmic radiation.
The origin and then modern significance of Charles Darwin's theory of natural selection is discussed.
