Imagine you’ve just started a new job or it’s your first day at uni. You’re talking to your boss or teacher, someone who’s much older, much richer, or much more powerful than you. Do you call them by their first name? Or do you go with Mr, Mrs, Professor, Doctor?

In Nigeria, a video of a young woman being corrected for calling a billionaire businessman, Tony Elumelu, by his first name has sparked a conversation about respect, age and power.

We speak to three Nigerians to get their take on the story and how you should refer to your boss.

Investing used to be seen as something that was for older people in suits, but now more young people are getting into it, thanks to the rise in online investing apps that have made it more accessible, and a growing awareness of how stocks and shares work.

But data suggests that despite being less likely to start investing, women often make higher returns than men when they do. So, why are women often better at investing? And how does it work?

BBC business reporter Emer Moreau unpacks the data on how women and men invest differently, what investing is and why it can be risky. We also chat to Viktoriia and Gabriella, two women in their 20s, about why they started investing and how they are finding it.

Videos from the second edition of the World Humanoid Robot Games in Beijing have been going viral. Two thousand robots from 16 countries took part and the robots seem more human-like than ever. They dance, compete in boxing matches, sprint faster than Usain Bolt, and even lift weights (not always successfully).

BBC China Analyst Kerry Allen explains how the Games relate to China’s international and domestic goals. Among other things, China’s leaders want to show the world how advanced their robotics industry is and demonstrate advances that will allow robots to strengthen China’s workforce.

We also hear reactions from content creators Christina Ernst in the United States, Uchechukwu Ololo in Nigeria and Cheryl Liu in China.

Tradwife content is everywhere - you’ve seen it on your feed. Influencers showing off their sourdough loaves while talking about how lucky they are to be stay-at-home wives, mothers, and girlfriends. For some, it looks like an aspirational lifestyle - fairy-tale wealth, a beautiful home, family and no 9-5 job.

One of the biggest accounts like this is Nara Smith. And although she’s often seen as the face of the movement, she’s now said she doesn’t identify with the label.

Others using the hashtag on their content say the same.

We chat to Crystal Gorsuch, who is 20 and a stay-at-home mum. What does she think of the label and how has her content been received by people online?

Plus, Chelsea from the team talks to us about how this trend is changing and where it might go next.

Dolly Parton was a country music star like no other. Following her death from cancer on Tuesday, everyone from President Donald Trump to Beyoncé has expressed condolences online.

William Lee Adams, a BBC culture reporter, explains why Dolly’s legacy has only grown with time. We discuss her uplifting personality, endlessly quotable quotes, and philanthropic endeavours — from donating a million dollars to help fund the Moderna Covid-19 vaccine to the Imagination Library, her charity that has gifted children more than 200 million free books.
