Kate Adie introduces stories on India's 'cockroach' protests, anger in Ukraine over army recruitment, the Iranian school bombed at the start of the war, fears over voting changes in America's deep south, and the bio-hacking phenomenon in Berlin.

The Cockroach Janta Party, or CJP, is now one of India's most visible youth movements, driving tens of thousands of students to take to the streets to protest about education, corruption, and a lack of job opportunities. Azadeh Moshiri met demonstrators in central Delhi.

President Zelensky’s decision to replace Ukraine's popular defence minister Mykhailo Federov triggered an outburst of anger this week. The country's military is struggling on several fronts - not least when it comes to signing-up new soldiers. Sarah Rainsford reports on the growing hostility around conscription.

In Iran we return to the opening hours of the conflict back in February, when a strike on an Iranian school transformed an ordinary Saturday morning into one of the war's defining tragedies - and its deadliest single incident for civilians. Nawal Al-Maghafi returned to the scene in Minab.

In Alabama, there is concern that a recent decision by the US Supreme Court could roll back hard-earned civil rights victories which protected the interests of minority African-American voters. Brandon Drenon has been speaking to voters in Tuskegee.

And so-called bio-hacking – using data to optimise one’s health, mental performance, and longevity - is being embraced by start-ups across Europe. Simon Busch has been finding out more in Berlin - one of the industry’s thriving hubs.
