The Frontline in the War on Corruption

Can you change a nation's attitude to corruption? It seems both Tanzania and Brazil are trying to prove that it's possible. In Brazil, President Dilma Roussef is fighting for political survival in the wake of the Petrobras scandal. In Tanzania, President John Magufuli has promised to sweep corruption away. BBC Brasil's Camilla Costa and BBC Africa's Zuhura Yunus compare notes on how you get rid of a culture of corruption.

Fleeing Chernobyl
In the week that the world marks the 30th anniversary of the Chernobyl disaster, BBC Ukrainian's Anastasia Zanuda remembers her flight from Kiev after the explosion. The authorities had blocked roads to stop people leaving, but her father was a mushroom picker and his knowledge of back roads enabled them to get to the Crimea, away from the deadly radiation.

Radio listening in Syria
Regular power cuts make it difficult for Syrians to get their usual television shows, so radio is filling the gap. Some of the space is filled by social programmes giving advice on how to get by in war conditions. Where to find tomatoes for instance, how to cope with intermittent water supplies, or even tips on how to give birth at home. Amira Galal from BBC Monitoring has been looking at the explosion of FM stations across the country.

In praise of the shehnai
It's a hundred years since the birth of legendary Indian musician Bismillah Khan, whose name will forever be associated with the shehnai. This is an instrument similar to the oboe, which he made famous in post-independence India. He was only the third classical musician ever to be awarded India's highest civilian honour - the Bharat Ratna. Fifth Floor fans of Bismillah Khan and the shehnai - Rupa Jha of BBC Media Action and Vandana Dhand from BBC Delhi - share their enthusiasm.
