Two flights have made the headlines recently after being hit by severe turbulence. Early investigations into a Singapore Airlines flight say that the plane dropped around 54m over 4.6 seconds. One passenger died of a suspected heart attack and dozens were injured.

Injuries from turbulence is pretty rare but scientists think that climate change could be making severe turbulence more likely in the future. The BBC’s climate and Science reporter, Esme Stallard, joins us to explain what causes severe turbulence and what scientists are doing to limit it.

It’s not just planes that fly, birds also have to deal with stormy weather. Researchers are now studying our feathered friends to better understand and predict turbulence. Emily Shepard, a researcher in bird flight and air flow, tells us how this might help.

In June Europeans will go to the polls to decide the make-up of the next European Parliament. Far-right parties are expected to make significant gains in several countries, including Germany — the most populous country in the European Union.

Alternative for Deutschland (AfD) — Germany’s most popular far-right party — have been using social media, especially TikTok, to appeal to younger voters. Their political rivals, including Chancellor Olaf Sholz and his Social Democratic Party, are now playing catch-up when it comes to TikTok.

The BBC’s Kristina Volk explains who the AfD are and describes some of the controversies surrounding them during the current election campaign. TikTok specialist Marcus Bösch describes the growth of the AfD on the platform. And we hear from Maggy Hess, who started the #ReclaimTiktok campaign, which makes viral content to counter the influence of the AfD.

China and South Korea are arguing on social media. This time it’s over K-pop group IVE’s new video for HEYA: some people in China claim that the group is passing off Chinese culture as Korean.

This isn’t the first time the neighbouring countries have had disputes about the origin of certain cultural things. There have been spats involving BTS, Squid Game, fashion, and - one that’s still fermenting - kimchi. The BBC’s Kerry Allen and Fan Wang talk us through the what and why.

Coral around the world is turning white and even dying as recent record ocean heat takes a devastating toll. It has triggered the fourth “global mass coral bleaching event”. Hannah chats to What in the World producer Kevyah Cardoso about the magical life of coral.

BBC climate reporter Georgina Rannard explains what’s causing this bleaching and whether the coral can recover from it. And we hear from two parts of the world where people are trying to monitor and revive their coral reefs. The BBC’s Alfred Lasteck in Tanzania tells us about his visit to the Mnemba Island, Zanzibar where they are restoring the coral reefs. And 19 year old environmental activist and divemaster Emma Batty Sukerta, whose family are from Bali, Indonesia, talks about why she is recording the sounds of the coral reefs there.

Thousands of young people have been out protesting in Georgia. But this isn’t organised by the opposition or a political party - these demonstrations are being driven by the 20 year olds themselves. It’s all because of a “foreign agents” law the government there is trying to bring in. There’s a fear that this law will suppress dissent and prevent Georgia from eventually joining the European Union.

This law will require non-governmental organisations and media outlets that receive more than 20% of their funding from abroad to register as an "organisation serving the interests of a foreign power". Don’t worry, we’ll go through it all in the episode.

The government says the law aims to increase transparency. Critics refer to it as the “Russian law” because it mirrors similar legislation introduced by Russian President Vladimir Putin in his country.

Nutsa Dzandzava (22) and Dato Dolaberidze (23) have been spending their spare time on the streets of Georgia’s capital Tblisi. We hear why they’re protesting and what they hope to achieve. The BBC’s Rayhan Demytrie explains a bit about Georgia’s history with Russia - and the details of the controversial law that started the protests.

This year’s Olympics will, for the first time, feature breaking – a style of street dance that originated in 1970s New York City. It’s characterised by acrobatic movements, speedy footwork and a hip-hop soundtrack. More than 30 breakers from all over the world will compete.

Rachael Gunn, from Australia, is one of them. She tells us what she loves about the sport, and why it’s so physically demanding. And BBC Sport Africa reporter Isaiah Akinremi explains what else to look out for this year — including an Opening Ceremony on the River Seine.

As India votes in the general election, it is impossible to avoid the wealth of AI-generated content being created - from campaign videos, to personalised audio messages in a range of Indian languages, and even automated calls made to voters in a candidate's voice.

Prime Minister Narendra Modi has also already made the best of the emerging technology to campaign effectively - addressing an audience in Hindi which, by using the government-created AI tool Bhashini, was then translated into Tamil in real time.

But as the tools get more sophisticated, experts worry about its implications when it comes to making fake news appear real. In April, two viral videos showed Bollywood stars Ranveer Singh and Aamir Khan campaigning for the opposition Congress party. Both filed police complaints saying these were deepfakes, made without their consent.

The BBC’s Meryl Sebastian, who is based in Kochi in southern India, explains how the election is playing out amidst the wave of AI and deepfake content.

Plus we get advice on how to deal with AI and deepfake material as a voter from Divyendra Jadoun, founder of The Indian Deepfaker, who creates this exact content.

Iran’s President Ebrahim Raisi, and several other officials, including the foreign minister, have died in a helicopter crash. Mr Raisi was widely tipped to eventually become Supreme Leader, the most powerful role in the country.

The BBC’s Shayan Sardarizadeh explains who Mr Raisi was, how power works in Iran, what the reaction has been, and what this could mean for the future of the regime.
