BTS are back! It’s the first time all seven members have been together since completing mandatory military service in South Korea. They’ve returned with a 14-track album titled Arirang and an 82-date world tour. Fans in South Korea were treated with the opportunity to see them for free in a huge opening night show in Gwanghwamun Square in Seoul.

BBC Korean’s Yuna Ku tells us what it was like be at the comeback show. Plus we hear from those who watched the concert on Netflix from across the globe. Music journalists Clint Edwards and Chase Karng also give us their first impressions of Arirang.

The White House is stepping up their social media promotion on the war in Iran... with memes. Clips from the NFL, Spongebob Squarepants and Call of Duty have all been spliced together with scenes military strike footage from the Iran war, racking up millions of views on TikTok. President Trump’s team say it’s a modern way to get their message across to young audiences and show their military successes, but the comments show that not everyone agrees, and some argue that it trivialises the human cost of war.

Anthony Zurcher, the BBC’s North America correspondent, explains it all - and tells us how this compares to the tactics previous US governments have used to depict conflicts. And social psychology Professor Sander van der Linden, who’s from Cambridge University, tells us how these hype videos can affect our perception of the war.

Looksmaxxing has been all over the internet lately - this is the trend aimed at young men and it’s based on the idea of self-improvement, maximising your physical attractiveness and increasing your sexual market value. It's been part of fringe reddit forums for years now but recently it’s become mainstream, with the hashtag going viral on TikTok, X and Instagram.

The trend promotes extreme dieting, obsessive body ranking and pseudo-scientific cosmetic advice - including a recent "bonesmashing" trend which has been condemned by doctors. And it has links to incel and manosphere networks. BBC journalist Thomas Morgan explains looksmaxxing and why it’s become popular with young men, as well as some of the real life consequences.

We speak to 22 year old actor Trevor Larcom about his own looksmaxxing journey and find out what he makes of the accusations of misogyny and toxic culture. And Stephen Imeh, who wanted to become the “first black looksmaxxer”, tells us about his experience.
