The Real Mobile Phone Wars - DRC, 10 October 2001
As the high tech age takes over more and more of our lives manufacturers will go to any lengths to get the sometimes scarce minerals that go into them. Tantalum is one such rare ingredient. Few of us know that in the middle of Africa much human suffering is created in the pursuit of it.

Coltan is a valuable metal because it can be processed and manufactured into a component called a capacitor, which sits on the circuit board of mobile phone and other portable electronic devices. The Democratic Republic of Congo is the world's second biggest supplier of coltan (after Australia), supplying an estimated 18 per cent of the world market. The trouble with coltan from Congo is that it is fuelling the war there. Various rebel groups and militias are mining, stealing, taxing and/or smuggling coltan to raise funds for their war effort. A recent UN report has declared the trade in coltan from Congo illegal because the legitimate and internationally recognised Government of the Democratic Republic of Congo does not license it. Instead the trade of coltan is helping to destabilise that government. Our reporter, JULIANA RUHFUS, travels via Uganda across the Kasindi border crossing, to Congo, her quest to find the source of coltan. Her often dangerous journey takes her via coltan traders, miners and warlords including the Mayi Mayi.

A report by Juliana Ruhfus for Unreported World. Produced by Mentorn. Ref. 1170

In ‘Unreported World’ we’re in the Congo with a tribe under threat, as the forest they hunt for food in is put off limits to protect the wildlife. The Baka tribe tell us of threats and intimidation by the proposed park’s guards who are part-funded by the World Wildlife Fund.
Ade Adepitan travels deep into the rainforests to see how the Baka are fighting for food. Is the survival of endangered species being put above their own?
WARNING: You may find scenes of
butchered animals upsetting.

Where the foothills of Mount Kenya merge into the desert, the people of Samburu have maintained a strict patriarchy for over 500 years in northern Kenya. That is, until 25 years ago, when Rebecca Lolosoli founded Umoja village as a safe haven for the region's women. Umoja, which means "unity" in Swahili, is quite literally a no man's land, and the matriarchal refuge is now home to the Samburu women who no longer want to suffer abuses, like genital mutilation and forced marriages, at the hands of men.
Throughout the years, it has also empowered other women in the districts surrounding Samburu to start their own men-excluding villages. Broadly visited Umoja and the villages it inspired to meet with the women who were fed up with living in a violent patriarchy.

Probability is the backbone of science, but how well do you understand it? Odds are, not as well as you think; it is a surprisingly subtle concept that is often misunderstood, sometimes even by professionals who use it to guide crucial and far-reaching decisions. In this program, experts from technology, physics, medicine, and programming explore the slippery side of probability and the powerful role it plays in modern life.
This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
Original Program Date: May 30, 2015
Host: John Hockenberry
Participants: Robert Green, Leonard Mlodinow, Masoud Mohseni, Alan Peters

It’s happened. The first children genetically engineered with the powerful DNA-editing tool called CRISPR-Cas9 have been born to a woman in China. Their altered genes will be passed to their children, and their children’s children. Join CRISPR’s co-discoverer, microbiologist Jennifer Doudna, as we explore the perils and the promise of this powerful technology. It is not the first time human ingenuity has created something capable of doing us great good and great harm. Are we up to the challenge of guiding how CRISPR will shape the future?
PARTICIPANTS: Jennifer Doudna, Jamie Metzl, William Hurlbut

Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.
The lecture explores how the introduction of new notation has paved the way for new leaps in understanding, and considers some mathematical quirks of language, such as what the number 4 in English has in common with the number 11 in Russian.
