Sharks off the coast of Brazil recently tested positive for cocaine in lab research by The Oswaldo Cruz Foundation. It was the first study to detect cocaine in the species. It’s not yet known how the drug affect the predators.

It’s not just sharks ingesting man-made substances. Marine experts have found traces of painkillers, contraceptive pills, anti-depressants and MDMA in other aquatic creatures. Crabs and fish have demonstrated significant behavioural and psychical differences as a result.

We get a round up of the research from Alex Ford, a professor of biology at the University of Portsmouth. He explains how recreational drugs and medicines have been found in seawater samples in the U.K. and how that could impact animal behaviour and development.

There are loads of podcasts about entrepreneurship, setting up a business or start-up, being your own boss and making money. According to the American business magazine Forbes, up to 9 in 10 start-ups fail, and the number is thought to be even higher in Africa.

Chidimma Adetshina, a 23-year-old law student, has been facing online abuse since becoming a finalist in Miss South Africa 2024. Chidimma is South African and grew up in Cape Town to a Nigerian father and South African mother with Mozambican roots. Some people think she shouldn’t compete because of this - even though she is eligible.

BBC Africa journalist Danai Nesta Kupemba talks us through the details, and what this says about xenophobia and ‘afrophobia’ more generally in South Africa.

This isn’t the first time there have been issues over the Miss South Africa beauty pageant. Melissa Nayimuli - whose father is Ugandan - competed last year and also faced online abuse. She joins us to share her experience.

This podcast was recorded on Wednesday lunchtime in the UK. On Wednesday evening, the South African government released a statement saying there was an ongoing investigation into fraud and identify theft involving Chidimma Adetshina’s mother, in order to become a South African citizen. On Thursday, Ms Adetshina announced she was withdrawing from the contest “for the safety and well-being” of herself and her family. She did not refer to the investigation.

There are celebrations in Bangladesh following Prime Minister Sheikh Hasina’s resignation after weeks of violent unrest.

Many have described the past month as one of the worst periods of violence seen in Bangladesh since the country formed five decades ago. Student protests against quotas in government jobs escalated into an anti-government movement after a violent crackdown by security forces and pro-government student groups have seen around 400 people killed.

The country remains in a state of chaos after the Prime Minister hastily fled the country before protestors stormed her official residence.

Until recently, 30% of civil service roles in Bangladesh were reserved for the children and grandchildren of people who fought for the country’s independence back in 1971, a system protestors said benefitted those close to the ruling party.

Protestors share their experiences and our BBC reporter in Dhaka, Akbar Hossain, explains how the student protests changed course and dramatically ended the 76 year-old leader’s 15 year reign. We also hear from Rani Singh, who previously interviewed Sheikh Hasina at her palace.

Animals are essential in maintaining ecosystem balance, but in some cases they can have the opposite effect. In the coastal city of Mombasa, Kenya, authorities are looking to cull 1 million Indian house crows. Conservationists say they are becoming a nuisance and have significantly reduced the number of small indigenous birds in the region. So how will they be dealt with? The BBC’s Dorcas Wangira, an Africa health correspondent, explains.

Pest are an issue in New York too. There’s estimated to be 3 million rats scurrying around the Big Apple and the city’s mayor has made it his mission to deal with the rocketing number of rodents by hiring a ‘rat tsar’. Sam Cabral, a BBC reporter in New York, tells us more.

Finally, we hear from Predator Free Wellington, an organisation in New Zealand, which is hoping to completely remove predators (like rats and possums) by 2050.
