How we became the heaviest drinkers in a century May 06, 2019

Chrissie Giles on her generation’s climb to Peak Booze.

"I didn’t feel that I had a problem with alcohol, nor did any of my friends. We got drunk, sometimes too drunk, and then suffered the consequences. We were just doing what young people did. But recently, with getting on for 20 years of drinking under my belt, I started to wonder if my generation’s relationship with alcohol was abnormal. When I looked into the numbers I realised that it was. I discovered that 2004 was Peak Booze: the year when Brits drank more than they had done for a century, and more than they have done in the decade since. Leading the way to this alcoholic apogee were those of us born around 1980. No other generation drank so much in their early twenties. Why us?"

Hungary's cold war with polio Oct 29, 2018

"Polio was unpredictable. Often no more harmful than any other childhood infection, it could on occasion ‘turn’ with swift, inexplicable savagery, destroying a child’s nerve cells and leaving him paralysed for life. If it damaged the nerves controlling his lungs they could freeze up and György would either die or spend the rest of his life inside an iron lung that breathed for him."

Trapped by the Cold War and scarred after a failed revolution, Hungary fought one of its greatest battles against polio.

What the nose knows Oct 15, 2018

"Losing enjoyment of food and drink is a common complaint for people who lose their sense of smell. You can taste sweet, salty, bitter, sour and umami with your tongue. More complex flavours – like grapefruit or barbecued steak – depend on smell. But for Nick, as for many people who can’t smell, there’s another category of loss altogether."

Losing your sense of smell can fundamentally change the way you relate to other people.

People are animals, too Aug 06, 2018

"We gaze into the eyes of a chimp and see a reflection of ourselves. We glance at a crow and see an alien being that under some jurisdictions can be exterminated with impunity - bringing a sinister second meaning to the phrase "a murder of crows". Such biases affect ordinary people and academic experts alike, skewing our understanding of what non-human intelligence looks like."

"Cholera has killed nearly 9,000 Haitians. More than 730,000 people have been infected. It is the worst outbreak of the disease, globally, in modern history. Hundreds of emergency and development workers have been working alongside the Haitian government for five years, trying to rid the country of cholera, and millions of dollars have been dispense in the fight to eradicate it. But it's still here. Why?"

Can India’s urban future be a healthy one? Jul 09, 2018

"As more Indians adopt more urban lives, chronic conditions like diabetes, obesity and heart disease are on the rise, replacing malnutrition and infectious diseases as the country’s most urgent health worries. Reddy doesn’t want to risk his family’s health. He has decided that being healthy and poor is better than taking their chances in the modern, more developed, more open India."

Ill-health is the price rural Indians have to pay for seeking a better life in the city. Twenty-nine villages near Hyderabad are helping to explain why, Michael Regnier discovers.

Brazil's cancer curse Jun 11, 2018

"Gomez is one of Achatz's regular patients at the A C Camargo Cancer Center in São Paulo, Brazil. He is extraordinarily susceptible to cancer. So too are many members of his extended family; cancer is so common among them - and premature death so painfully familiar - that until they learned very recently of the cause, some believed their family was cursed. Gomez's is not the only family affected. The 'cure' afflicts hundreds of thousands of people in Brazil."

The startling discovery that hundreds of thousands of Brazilians have a genetic mutation that undermines their ability to resist cancer is helping labs worldwide in their search for new treatments for the disease. Sue Armstrong reports."

The worst sound in the world Apr 30, 2018

John Osborne has always hated the sound of whistling. But it wasn’t until a man whistling in a café infuriated him so much that he got up and left that he realised it was becoming a problem. Could he even be suffering from misophonia – a condition characterised by a strong dislike of certain sounds?

To get to the root of the issue, John embarks on a whimsical journey of self-discovery, diving headfirst into the worlds of professional whistling and psychology in an attempt to understand if he could ever learn to tolerate – or even love – the sound of whistling.

The troubled history of the foreskin Apr 16, 2018

"Men have been circumcised for thousands of years, yet our thinking about the foreskin seems as muddled as ever. And a close examination of this muddle raises disturbing questions. Is American exceptionalism justified? Should we really be funding mass circumcision in Africa? Or by removing the foreskins of men, boys and newborns, are we actually committing a violation of human rights?"

Common in the US, rare in Europe and now championed in Africa, male circumcision is hotly debated. Jessica Wapner explores whether the gains are worth the loss.

Death in the outback Feb 19, 2018

"Almost 30 per cent of children in care in Australia come from an Aboriginal background: 'The Stolen Generation - when Aborigines were forcibly taken away from their families - may not just be a shameful part of Australia's history...'. 'Is this seriously happening, in 2014?' I wonder. Most Australians are aware of the Stolen Generation, when it was legal for the government to take Aboriginal children away from their families. But this forced separation, I thought, had ended decades before."

Healthcare in Australia’s Aboriginal communities is hindered by a long history of racial discord between very different cultures. Georgina Kenyon discovers the story of one young woman who died in the 1980s, and asks whether anything has changed since.

"By the end of that day the September 11th Fund had been established by two major local charities. Donations poured in. Money first went on immediate aid - hot meals for rescue workers, emergency cheques for victims and their families - and then funds were made available for programmes to help New Yorkers to recover.

Written by Emma Young, read by Kirsten Irving, produced by Barry J Gibb, edited by Geoff Marsh.
