At 7,000 kilometres (4,350 miles), the Nile is Africa’s longest river. But a mega project, the Grand Ethiopian Renaissance Dam, has triggered a major dispute in the region.While Addis Ababa says the dam is crucial to its economic development, Cairo calls it an existential threat. And Khartoum fears the project will increase the risk of flooding and affect the safe operation of its own dams on the river.Can Ethiopia, Sudan, and Egypt find a diplomatic solution to their dispute, or will it escalate further? Sudan’s Irrigation Minister Yasser Abbas talks to Al Jazeera.-

Congo Connection (2009): The mineral Coltan has fuelled a technological revolution in the West, but in the DRC it has become a talisman of brutal violence.

Modern technology relies upon a mineral found in the Congo. Is our appetite for the latest gadgets fuelling rebel fighting in the Congo - threatening the survival of central Africa’s great gorillas?

On the inside of many devices like mobile phones and laptops is the mineral ‘Coltan’, which has made our gadgets smaller and more complex. In the mineral-rich Congo, armed militia watch over the children digging this mineral from the ground. “"The government only pretends to help us"” says one miner, who pays a government official just to work. “"The Congo is a shifting sands of various militia, the largest of which is the Congolese state itself”," explains an expert on blood minerals.

Yet the miners depend on the little they get from mining to survive. Electronic giants like Apple now claim they will no longer use Coltan from this area but experts are convinced the militias will “smuggle it onto the market” regardless. For local miners, the move away from African minerals is “just another way of penalising Africans”. Coltan fuels a conflict, which has seen national parks become war zones, gorillas killed for meat and hundreds of houses set on fire in turf wars over mineral territory. Yet it also feeds 400,000 petty traders. Why did it take a mobile phone to make us appreciate the injustice in the Congo?

What is quantum biology? Philip Ball explains how strange quantum effects take place in the messy world of biology, and how these are behind familiar biological phenomena such as smell, enzymes and bird's migration.

In this guest curated event on quantum biology, Jim Al-Khalili invited Philip Ball to introduce how the mysteries of quantum theory might manifest themselves at the biological level. Here he explains how the baffling yet powerful theory of the baffling yet powerful theory of the subatomic world might play an important role in biological processes.

Philip Ball is a science writer, writing regularly for Nature and having contributed to publications ranging from New Scientist to the New York Times. He is the author of many popular books on science, including works on the nature of water, pattern formation in the natural world, colour in art, and the cognition of music, and he has also broadcast on many occasions on radio and TV.

Jim Al-Khalili is Professor of Theoretical Physics and Professor of Public Engagement in Science at University of Surrey. He is author of several popular science books and appears regularly on radio and television. In 2007, he was awarded the Royal Society Michael Faraday Prize for Science Communication.

This event took place at the Royal Institution on 28 January 2015.

Loop quantum gravity aims to unify the theories of general relativity and quantum mechanics, as explained by Jim Baggott.

Quantum gravity is the holy grail for modern theoretical physicists – a single structure that brings together the two great theories of the 20th century: quantum mechanics and general relativity. One widely-known solution is string theory, which emerged from particle physics. In this talk, Jim Baggott will describe the other approach known as Loop Quantum Gravity. This theory starts from general relativity, borrows many ideas and techniques from quantum mechanics, and predicts that space itself is quantum in nature.

Jim Baggott is an award-winning science writer. He trained as a scientist, completing a doctorate in chemical physics at the University of Oxford in the early 80s, before embarking on post-doctoral research studies at Oxford and at Stanford University in California.

This talk was filmed at the Ri on 12 February 2019.
