After vowing that nothing could stop him from running for re-election, US President Joe Biden has dropped out of the 2024 presidential race and endorsed Vice President Kamala Harris to take over.

He didn’t just fall out of a coconut tree, he exists in the context of what came before - so we explain how he got here.

He made the announcement via a statement on social media, in which he said his decision was "in the best interest of my party and the country". It comes after weeks of intense suggestions from fellow democrats, voters and even George Clooney to drop out following a dodgy debate performance against Donald Trump.

He’s still president until January, when the winner of the 2024 election will take office. But in the meantime, what happens? How do we get there? And why on earth are so many people talking about coconuts? We explain what’s likely to unfold over the next four months.

A lot of us dream about becoming a professional athlete and the ultimate athletes in sport are at the Olympic Games. But what does it take?

Since the start of the month, university students have been protesting across Bangladesh, asking for quotas in government jobs to be removed. 30% of roles are reserved for the children and grandchildren of people who fought for the country’s independence back in 1971.

The anti-quota protesters have clashed with members of a pro-government student group and police.

Things have escalated this week and at least ten people have been killed.

Akbar Hossein is from BBC Bangla in Dhaka - he explains what the quota system is and why students want to change it.

A new strain of the mpox virus is spreading quickly in the Democratic Republic of Congo, and experts say it is the most dangerous variant they have seen.

We chat to Makuochi Okafor, a BBC Africa health reporter, who explains the symptoms of mpox, why scientists changed its name, and how people can protect themselves. He also describes what we know about the new variant.

In 2022, a global outbreak of the virus spread across the world. The World Health Organisation said more than 87,000 cases were recorded in 111 countries. We hear what it was like for some people who caught it.

And BBC Health reporter Philippa Roxby tells us how that outbreak was controlled, and the role public information and vaccines played. With not enough vaccines in Africa, can authorities stop the spread this time?

This weekend, traffic in a key part of Mumbai came to a standstill to make way for a convoy of VIP guests attending one of the year’s most talked about events, the wedding ceremony of Radhika Merchant and Anant Ambani.

On Saturday evening someone tried to kill Donald Trump. The former president was giving a speech at a political rally in Pennsylvania when a gunman took aim from a nearby rooftop. The bullet grazed Mr Trump’s right ear before he was rushed to safety.

Images of the defiant presidential candidate, moments after the incident, standing with his fist raised, lines of blood streaked across his face, could impact the election. We look at why. We also discuss security and how the gunman managed to get past US Secret Service agents.

JailTime is a record label that aims to get prisoners away from crime and into the music industry. It operates from a studio in New Bell prison, a high security jail in Douala, Cameroon. They say they’ve brought reoffending rates down significantly.

JailTime’s founders, Dione Roach and Steve Happi, tell us what they're trying to achieve and talk about one of their success stories; Moussinghi.

On the other side of the world, the USA has one of the highest recorded reoffending rates in the world. Can arts programmes prevent offenders returning to crime? Maurice Chammah from the Marshall Project gives us his take. He also talks us through the history of music in prisons and describes how prisoners manage to record music from their cells unofficially.

Over the last 18 months the world has gone pretty crazy about AI. Apple has been jumping into the space and Samsung is forecasting higher profits than ever from its advanced chips. Tech companies say it’s the future and may even put a lot of us out of a job. But a new report from one of the world’s top banks says that generative AI, things like ChatGPT or Gemini, might not prove to be the gamechanger that tech companies have been promising.

Generative AI also uses huge amounts of energy and water, behind the super smart tech are massive data centres that drive up greenhouse gas emissions. So we’re asking is AI really going to be worth the cost to our wallets and potentially our planet?

Imran Rahman Jones, a BBC Tech Reporter, tells us how the drive for AI has bumped up Google’s emissions by almost half and explains the ways tech companies are trying to compensate for the surges.

We will take you to Spain, Southern Africa and Hawaii to discuss the tension between the money that tourism brings in, and the price locals have to pay.

There’s loads of misinformation online about vaccines. For years, there have been false claims about the tetanus jab causing infertility. One of our listeners, Henry, got in touch to ask us if they were true. Fauziyya Tukur, a BBC Disinformation journalist in Abuja, looks into the claims with us.

The BBC's medical editor, Fergus Walsh explains why vaccine hesitancy is on the rise around the world - and the impact vaccines have had on global health. And we hear from Sahar Baloch, a BBC journalist in Islamabad, who talks about efforts to eradicate polio in Pakistan, amid misinformation about the jab (fuelled in part by a CIA fake vaccine campaign to seek out Osama bin Laden!).
