The U.S. Agency for International Development (USAID) is under fire. It is the world’s biggest donor and spends billions of dollars a year, funding programmes around the world, like fighting malaria in Bangladesh, clearing unexploded landmines in Cambodia and Laos and providing medical supplies in Sudan.

But President Trump says it is run by “radical lunatics” and he and billionaire Elon Musk, who’s got the job of trying to slash American government spending, want to shut it down. They have paused almost all international spending for 90 days and issued “stop work” orders to their staff. BBC journalist Nathalia Jimenez tells us what USAID does - and why the Trump administration wants to close it.

A large proportion of USAID funding goes towards healthcare and HIV medication in sub-Saharan Africa. Makuochi Okafor, the BBC’s Africa Health correspondent tells us what impact closing USAID could have in this region.

Anselm Gibbs, a BBC reporter based in Trinidad and Tobago, tells us about programmes USAID funds in the Caribbean. And Hilde Deman from Search for Common Ground, an international NGO that uses USAID funding in countries affected by violent conflict, talks about the impact to their work in the Democratic Republic of Congo.

More young men are inquiring about and getting vasectomies. It’s a trend that’s been observed informally in several countries, and has particularly spiked in the United States since the Supreme Court’s decision to overturn Roe v Wade.

But what exactly does the procedure involve? Dr Jeff Foster specialises in men’s health. He talks us through the procedure, and debunks some common myths about pain, semen and erections. We also hear from two men - in the US and Kenya - about why they chose to have ‘the snip’.

Forget dating apps or meet cutes... marriage matchmaking is back. Young people in South Korea have been signing up to professional agencies to find love, and sales are booming.

Our reporter Rachel Lee has been speaking to young people in Seoul to find out more.

We also run around our global office and ask: would you use a matchmaking service? (The reaction was surprisingly mixed…)
