Gold Dust: Under Blaise Compaore's leadership, Burkina Faso's unregulated gold rush has had a devastating effect on mining conditions. This report digs deep into the industry, exposing the corruption beneath Compaore's ruling.

Millions of people - including children as young as fourteen - mine in an unregulated industry for a few golden grams of hope. Marcel toils underground to support his family - but without the glittering rewards promised. “We all have hope, we hope to earn” he says, but "they rob us here...They treat the miner like an animal." 17-year old Soumaele has been mining for two years. His thin body can go to even deeper than the older men, to places where the air is impossible to breathe and the tunnels are likely to collapse. Gold promises a great deal, but in an anarchic industry, teacher Soungalo Hema fears for the future of children like Soumaele: "You try and save them", she says, "but a lot of the time it’s in vain. I ask myself 'what will happen to all of us?'"

Nigeria's government has repeatedly said it has defeated Boko Haram.
Yet after more than 10 years of fighting the armed group, violence is on the rise in the northeast.
Boko Haram is suspected of being behind an attack on Saturday that's described as the most violent on civilians this year.
The UN says at least 110 people were killed in the assault on farmers in rice fields near Borno State's capital Maiduguri.
So what's been done to fight Boko Haram?
And can it be defeated?

From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.

Watch the Q&A: https://youtu.be/NXcu0BlbTrM

Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.

Carlo Rovelli is a theoretical physicist who has made significant contributions to the physics of space and time. He has worked in Italy and the US, and is currently directing the quantum gravity research group of the Centre de physique théorique in Marseille, France. His books 'Seven Brief Lessons on Physics' and 'Reality Is Not What It Seems' are international bestsellers translated into forty-one languages.

This talk and Q&A was filmed in the Ri on 30 April 2018.
