For the past 100 years diamonds have been the ultimate symbol of love, luxury and opulence. But then, a darker side to them was exposed. Diamond mining was shown to have links to conflict, human rights abuses and state corruption, putting off a lot of consumers. Lab-grown diamonds then appeared on the market as a more eco-friendly, ethical and cheaper alternative, but do they have the same appeal?

We speak to Caroline Steel, a BBC Science presenter, about what makes the gems so precious and the science behind how diamonds are formed.

We also hear from Shingai Nyoka, a BBC Africa reporter, about Africa’s relationship to diamond production, and the discovery of the second-largest mined diamond in Botswana in August.

The war in Gaza has lead to a surge in settler violence. Extreme Israeli settlers are the perpetrators behind the attacks. Not only have they become more aggressive, Israeli settlers have also seized more and more land.

One spokesperson from Peace Now, an Israeli organisation that monitors settlement growth, says Jewish extremists in the West Bank are exacerbating an already tense and volatile situation, and making it harder than ever to end the Israel-Palestinian conflict. So will these settlements will permanent? The BBC’s Middle East correspondent Yolande Knell explains.

On Wednesday Israeli forces launched a "counterterrorism operation" in the occupied West Bank which includes air strikes and ground troops in several Palestinian towns and cities - including in Jenin and Tulkarm.

Last week the newly announced CEO of Starbucks landed in hot water when it emerged that he’d be commuting from his home in California to the Starbucks headquarters in Washington using a private jet. The 1,600 km, three-hour commute stoked a wave of criticism online.

It’s not the first time a public figure has come under fire for their eye-watering air mileage; earlier this year media outlets began scrutinising Taylor Swift's carbon footprint after a student began posting her flight information online by using publicly available data to track the take-offs and landings of privately owned planes belonging to the rich and famous. Her lawyers threatened to sue him, saying that the tracking amounted to "stalking." In 2022, Twitter banned the same student’s profile after Elon Musk accused him of sharing his "assassination coordinates".

But when a four-hour private flight emits as much as the average person does in a year, climate campaigners say that the cost to the planet is not worth the convenience.

BBC business reporter Charlotte Edwards unpacks the Starbucks CEO’s controversial commute and lifts the curtain on the business of luxury air travel. And our climate and science reporter Esme Stallard explains the environmental cost of the industry.

This week we’ve had the release of what is, right now, the most popular game in the world - but it’s not a new version of GTA or Minecraft - this one is from China and it’s called Black Myth: Wukong. There are predictions it’s going to make hundreds of millions of dollars - and it now has more than two million active online players.

It’s been made by a relatively small Chinese company called Game Science and it’s the first time a game from the country has managed to break through internationally on this scale.

The BBC’s Kerry Allen, a China media analyst, describes the gaming industry in China - and the various restrictions gamers there face. And Mel Ramsay, a BBC journalist and video games expert explains why the game has become so popular inside and outside China - and some of the controversies around it.

Also, Kirk McKeand, a video games journalist in the UK who has played Black Myth: Wukong, gives us his take.

The Somali Parliament recently passed the National Disability Act. Twelve percent of the population in Somalia are estimated to be living with a disability. People with disabilities in Somalia have less access to formal education and higher rates of unemployment. This new law aims to protect their rights, make sure they get equal opportunities in jobs, education, and healthcare, and help reduce the stigma they face.

Fardowsha Hanshi, a BBC journalist from Somalia, explains what life is like in Somalia for people living with a disability and talks about her own experience of disability. She tells us what activists hope this new law will achieve. BBC journalist Ellis Palmer describes where the first disability legislation came from - and why implementation and individual advocacy is key.

And we hear from Kenyan Wilson Macharia, who is visually impaired and sued a company in Kenya for discrimination.

A legal battle has been raging after a woman suffered a severe allergic reaction and died at Disney World Orlando in Florida. The restaurant she ate at isn’t owned by Disney itself but her husband believes the entertainment giant does have some liability as well and tried to sue the company.

But here’s the catch - Disney’s lawyers said he couldn’t take the company to court because of terms in a Disney+ free trial contract he signed up to years before.

Disney has since backtracked on this argument after the case blew up on social media. But what are we really agreeing to when we tick the box on a terms and conditions document?

Graham Fraser from the BBC’s tech team takes us through the story at Disney World.

Plus Alex from the What in the World team goes into other weird clauses in contracts you might have signed.

Research shows that people in Africa are disproportionately rejected for visas over other nationals. While passport holders from Singapore can sail straight past immigration in many countries they visit.

To understand the unfair disparities that exist between passport holders, we speak to Stephanie Hegarty, the BBC’s global population correspondent. We learn about the new version of the Henley passport index (which lists the strength of passports), and why nationality plays a huge role in shaping the outcome of a person’s visa application, especially to countries in the West.

The BBC’s Tessa Wong, a Singaporean national, explains why her passport ranks the strongest in the world. And Daniel Dadzie, a BBC reporter, tells us about his personal experience of applying for a student visa to study in the UK from Ghana.

More incidents of rape have made headlines in India since the trainee doctor was killed.

Bebika Dhurve, a dentist who has worked in hospitals, tells us her reaction to what’s been happening.

And Arunoday Mukharji is our correspondent in Delhi. He takes us through the story and what challenges female medical professionals face.

MrBeast is the world's biggest YouTuber with more than 300 million subscribers. He’s built an empire partly through so-called “stunt philanthropy,” where he surprises people with large sums of money or gifts. MrBeast has given waiters thousand-dollar tips, gifted people new cars and houses, and even paid for surgery to help 1,000 deaf people hear for the first time. The recipients’ reactions are then filmed and put on his channel.

Tom Gerken, a BBC technology reporter, explains why some people don’t consider MrBeast’s stunt philanthropy particularly philanthropic and how he — and other YouTubers — make money through advertising and brand sponsorships. He also briefly explains the allegations facing MrBeast and some of his colleagues.

We also hear from Makuochi Okafor, a BBC reporter in Lagos, to find out how the trend is taking off in Nigeria.

A school girl in Zimbabwe was recently killed in a road accident which involved a US diplomat. Ruvarashe Takamhanya’s family are calling for the person involved to apologise to them in person. The US diplomat has now left Zimbabwe, and is back in the US.

Danai Nesta Kupemba, a BBC Africa journalist, has spoken to the family. She talks us through the case.

All diplomats have diplomatic immunity, which means they are protected from being arrested or prosecuted for alleged crimes. Alex Rhodes from the What in the World team explains why diplomatic immunity exists and who gets it. We also discuss prominent cases where diplomacy has been key - including with Julian Assange.

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.
