What in the World

Elon Musk could be about to become the world’s first trillionaire. That’s after a record-breaking pay package - that could be worth nearly $1tn (£760bn) - was approved by Tesla shareholders. The electric car boss is already the world's richest man, but this would take his wealth to a whole new level. But who is Elon Musk and how did he make all this money? We explain all, as well as breaking down what a trillion dollars actually is...

Children learn best when they’re taught in the language they use at home, research suggests. But there's the question about the power of world languages like English, Spanish, French or Arabic and how they could provide more opportunities to those who learn it, be it in education or a career.

You’ve been messaging us about what languages you learned in at school. Say hello to Brian in Kenya and Christian in the Philippines!

GPS interference or GPS ‘jamming’ is getting more common. It’s when radio signals on the same frequencies as GPS satellites are used to overwhelm and block legitimate navigation signals. It’s led to pilots having to make emergency landings or switch to older non-GPS systems. The issue has become so prevalent that the European Union Aviation Safety Agency (EASA) held a conference on it last year. Several European governments also be...

COP30, the big meeting where countries discuss climate change annually, has finished. This year it was hosted in the city of Belem in Brazil, in the Amazon forest, which is directly affected by it. The role of the two biggest emitters has also made headlines. The United States hasn’t taken part in the talks and China has kept a very low profile.

This summit has ended without a clear commitment to phase out fossil fuels and that has...

Scientists at Oxford University in the UK now think that kissing evolved more than 21 million years ago, and it wasn’t humans that started it.

As a behaviour, it has no obvious survival or reproductive benefits but it’s seen across the world, in humans and animals alike.

Victoria Gill, our Science Correspondent, tells us all about the research and what we know about if animals can be romantic like humans can.

Miss Mexico Fatima Bosch has been crowned Miss Universe at a ceremony in Bangkok, marking the end of an exceptionally scandal-filled pageant season. It's the 74th Miss Universe pageant and there was a lot of drama before a single contestant took to the stage.

Early in November, Miss Mexico walked out of an event after she was told off by a Thai official and those who supported her were threatened with disqualification.

Then in the d...

After months of mounting pressure, US lawmakers have just voted to release all of the so-called Epstein files. So documents from criminal investigations into the sex offender Jeffrey Epstein before his death could soon be made public. The vote was passed in the House of Representatives 427-1 and the Senate unanimously fast-tracked it without a formal vote. Now it’s down to US President Donald Trump, who’s already said he’ll release...

In Sudan, where a civil war has been raging for over two years, millions of students have had their education disrupted. Over half of all schools are in conflict zones. Many schools are being used as shelters and many students have missed their exams. In some parts of the country there is no education at all.

Sudan is one of the biggest countries in Africa. It’s mostly Muslim and is also one of the poorest countries in the world. Mo...

Both Jamaica and the Philippines have been battered by tropical storms in the past month. Hurricane Melissa, a category five storm, was the worst storm to ever hit Jamaica and one of the strongest so far to affect the Caribbean, leaving at least 30 people dead. And super-typhoon Fungwong displaced more than a million people in the Philippines, only days after an earlier storm claimed hundreds of lives.

Neither region is a stranger ...

These days, buying concert tickets is a huge expense. If fans miss out, they can often find tickets on resale sites at hugely inflated prices. Sometimes people resell their tickets because they can’t go but there are also lots of “professional resellers” or ticket touts playing the system and making loads of profit. They buy tickets in bulk from the original seller platform, then mark them up to fans.

We hear from a Taylor Swift su...

Prepping is a big deal in the US. There’s even a reality TV show called “Doomsday Preppers”. Prepping is when you stockpile loads of stuff - food, water, medicine - in case of a disaster, nuclear war or an unstoppable virus. Now billionaires are taking it to the next level, building underground mansions and self-sustaining bunkers that look like something out of a zombie apocalypse movie.

Meta CEO Mark Zuckerberg is building a $100...

Are Christians being targeted and killed in their thousands in Nigeria? That’s the claim made by US President Donald Trump in several social media posts. He’s blamed the Nigerian Government for allowing the killing of Christians, and has threatened to stop aid and send troops into the African country. It not only caught the attention of Nigerians, but also rapper Nicki Minaj. In a post on X that’s been seen more than 50 million tim...

Do aliens exist? What’s out there in the universe beyond Earth? These are some of the questions which have plagued astronomers and film producers for years.

Well, now astronomers are revisiting these questions following the discovery of a possible atmosphere around an Earth-sized planet about 40 light years away. The exoplanet is called Trappist-1e and may be able to host life.

The COP30 climate summit is taking place in the Brazilian city of Belém for the next two weeks. It's run by the United Nations (UN) and every year is one of the biggest events in the calendar, especially for world leaders and environmental campaigners. This COP is in the Amazon rainforest. The country's president, Luiz Inácio Lula da Silva, says it will be an historic summit because it is "a COP in the Amazon, not a COP about the A...

New York has chosen its new mayor - Zohran Mamdani. He’s a Muslim, was born in Uganda, and loves Arsenal. He’s also pretty young. The politician has been making waves online with his social media campaign and united a huge Gen Z force behind him. From viral moments like jumping in the sea in a suit to walking the entire length of Manhattan, he’s probably appeared on your timeline.

So, what made his campaign go down so well with you...

The Amazon rainforest is home to billions of trees, animals and people. It’s spread across nine countries in South America - Brazil, Peru, Colombia, Bolivia, Ecuador, French Guiana, Guyana, Suriname and Venezuela - but the majority of it, almost 60%, is in Brazil. As well as being rich in biodiversity, the Amazon is also very important in the world's fight against climate change; as it absorbs carbon dioxide and produces oxygen.

The RSF (Rapid Support Forces) have taken the city of el-Fasher, in Darfur, from the Sudanese army. The city had been under siege by RSF fighters for 18 months, trapping hundreds of thousands of civilians and sparking a hunger crisis. Thousands are now trying to flee. And there are mounting fears of mass killings and sexual violence - some of which are feared to be ethically motivated.

The civil war in Sudan has been going on since...

Sora and Vibes are making it easier than ever to make AI-generated videos. You may already be familiar with low-budget ‘AI slop’ which is creeping into TikTok and Instagram. Things like Will Smith eating spaghetti, dogs riding motorbikes, or the late Queen Elizabeth rapping. Or, maybe you enjoy POV videos - and imagining you’re an angel waking up in heaven, or the Pope in the Vatican. Now Sora, from the owners of ChatGPT, and Vibes...

Nauru is the third smallest country in the world. It’s located in the middle of the South Pacific Ocean and is home to around 12-thousand people. The tiny island has recently received its first transfer of foreign detainees from Australia - following a controversial deal between the two nations. The deal was struck after Australia's top court ruled that it could not indefinitely detain about 358 people, the bulk of whom have been c...
