Doctors demand social media data

It can provide instant access to information, communication with friends and online support. Children's screen time might even occasionally offer respite to frazzled parents. But doctors worry it could harm both body and mind, and report a growing number of children self-harming and attempting suicide as a result of online discussions. Now they are calling for tech companies to be forced to share data and pay a tax to fund further research.

The government is setting up an independent regulator for online safety. And the Royal College of Psychiatrists wants it to require social-media companies to share anonymised data on how youngsters use the likes of Instagram, Facebook and Twitter. "Time for... decisive action to hold social-media companies to account for escalating harmful content to vulnerable children and young people," says report co-author Dr Bernadka Dubicka. Industry body Tech UK points to existing research partnerships, such as a project with the Samaritans to deepen understanding of how people engage with harmful content.

If you're wondering how to navigate the social media minefield, our report contains psychiatrists' advice for parents.

Can a city go carbon neutral to stop climate change?

Domestic heating, industrial emissions, transport... many of the ways in which cities pump carbon into the atmosphere are largely out of local authorities' control.

Glasgow is among them and BBC News is reporting from the city throughout the day as part of the Our Planet Matters project. Hear what citizens make of the target.

If you're wondering what personal changes you can make to help reduce the impact of climate change, our Your Questions Answered series has been advising the audience.

What convinced the buyer to part with the sum? Well, the 22-carat gold disc - fractionally smaller and lighter than a pound coin - was one of a trial set of six coins featuring Edward VIII that never went into mass production owing to his abdication in December 1936. Read about the coin's quirky history.

When 'apocalypse' came to Kangaroo Island

By Shaimaa Khalil, BBC News

Kangaroo Island in South Australia has been likened to a Noah's Ark for its unique ecology. But after fierce bushfires tore through the island this week, there are fears it may never fully recover. "You see the glowing in the distance," says Sam Mitchell, remembering the fire that threatened his home, family, and animals last week. "The wind is quite fast, the glowing gets brighter - and then you start to see the flames."

Sam runs Kangaroo Island Wildlife Park and lives there with his wife and 19-month-old son, Connor. As the flames approached, an evacuation warning was issued. Within 20 minutes, "everyone was gone". But Sam - and four others - stayed behind. "You can't move 800 animals including water buffaloes, ostriches and cassowaries," he says.
