Science In Action - The final moments of DART
NASA’s latest mission, DART hit the headlines this week after the space agency’s satellite successfully collided with a far off asteroid. The mission acts as a demonstration of Earth’s first planetary defence system. Jon Amos, one of BBC’s Science correspondents, talks Roland through the final moments of the DART satellite. Although the collision was a success, we may have to wait a little longer before we know if the asteroid’s trajectory has been altered…
Simone Pirrotta, project manager at the Italian Space Agency, has more to add. His nifty camera system broke away 10 days before DART’s collision, ensuring its own survival. This celestial drive by is guaranteed to provide scientific data to get excited about.
Also this week, we visit the China Kadoorie Biobank. Twenty years in the making, it houses a collection of over half a million genetic samples, which might help identify links between our own genetic compositions and illness. Roland Pease visited them in Oxford to find out more.
Finally, a new review describes the use of mercury by ancient Mayans. The metal is famous for its use across a plethora of civilizations throughout history. Andrea Sella from University College London, tells Roland how his favourite element underpins industrialisation across the ages and the globe.

Stuff They Don't Want You To Know - Vigilante Justice: The Story of La Sombra Negra
In the wake of a horrific civil war, El Salvador found itself confronted with enormously pervasive, deadly gang activity -- it seemed the official law enforcement channels were often incapable of fighting back against the flood of crime. Until, that is, a new organization came out of the shadows -- unaccountable to authorities, unstoppable, and brutal. Today's question: What is La Sombra Negra? They don’t want you to read our book. They don’t want you to see us on tour.

A History of Rock Music in 500 Songs - A Request
Transcript
Hi. We're still on a skip week, the main podcast will be back next week, but as we've now reached a point in the podcast where more of the people discussed are living than dead, I'd just like to say something, and make a request. I've seen several people asking people mentioned in the podcast if they're listeners, on Twitter and other social media, and I would very much rather people stop doing that. Please don't tag any living subjects of my podcast episodes into tweets about those episodes. I can't stop you, of course, and I'm not meaning to shame anyone who has, as they've done it for the best of reasons, but it makes me extremely uncomfortable. I've had people take offence before at things I've written about their work which I didn't intend to be offensive. Creative people will often focus on a single negative aside in what is otherwise a wall of praise, and it can cause them real upset. I can't stop any subjects of podcast episodes from listening to them, but the podcast is not ultimately for them. The very best case scenario is that knowing those people are going to hear the podcast makes me uncomfortable and restricts what I say, making the podcast less good. The worst-case scenario is someone takes legal action because of something I've said, and the podcast has to end altogether. But mostly, I just know that if someone I've talked about is going to listen to my podcast, there's a good chance that they'll pick up on one casual remark I didn't even think about and ruminate about it all day. And I don't want to make people I admire have bad days. So please, do keep telling your friends about the podcast, but don't tell the stars I talk about. I know you all mean well when you do it, but it can cause far more harm than good.
