Upasana Taku is the co-founder of an app that changed the way millions of Indians use digital technology to make payments. Mobikwik now has more than a 150 million registered users.

When Upasana set up the business in 2009 with her co-founder Bipin Preet Singh, India was still a cash-dependant society, but having worked for big tech companies in the US, Upasana knew there was a gap in the market.

Devina Gupta asks her about her decision to leave a high-powered job in the US to move back to India to start a fintech company, and how she convinced both investors and her family that it was a smart business move.

In July, South Africa unveiled a new coalition government, after the ruling African National Congress (ANC) party lost its majority in May's elections.

The coalition was welcomed by the business community who said it would ensure economic stability.

So what's happened since? And will any optimism last?

Donald Trump's return to the White House has raised big questions about what he'll do to the US' growing green energy sector. On the campaign trail he promised to undo Joe Biden's Inflation Reduction Act, the biggest piece of climate legislation in US history. The IRA gives incentives and tax breaks for green industries and has created hundreds of thousands of jobs, many of those in Republican voting states.

President-elect Trump also pledged to end offshore wind "on day one" and reverse emissions rules aimed at increasing the number of electric cars on America's roads.

Will he keep those promises? And what of the influence of Elon Musk, the world's richest man, now in Donald Trump's inner circle? Is he worrying about what a Trump presidency might mean for his car company Tesla and will he be lobbying behind the scenes on behalf of electric vehicles?

We hear what people in those sectors think will happen under Trump 2.0. Can the renewables industry survive or even grow over the next four years?

Earlier this year, Manchester City midfielder Rodri issued a warning that players were "close" to taking strike action over their increased workload.

Rodri played 63 competitive games for club and country last season. But a recent report found that a player welfare 'red line' was a maximum of between 50 and 60 matches per season, depending on a player's age.

Some of the game's biggest names have joined Rodri in threatening to walk out, and the union that represents them is launching legal action against the sport's governing body, FIFA.

But there's a lot of money invested in football, so what's the likelihood the sport might change to stop players feeling over-stretched? And is strike action likely or even possible?

We find out why, in a country famous for championing gender equality, some women are choosing to become stay-at-home wives and girlfriends.

The social media #softgirl trend is a small but growing minority, who say they do not want the stress of juggling family and work. They want a 'softer' life - with more balance and not having to focus on a career. It has triggered cultural and political debates across Sweden where feminism has been a part of mainstream politics since the 1950s.

Ghana is a global gold mining powerhouse and Africa's biggest producer.

The informal mining sector of gold – known locally as “galamsey” - is a big election issue here. There have been recent marches demanding tougher action against illegal miners in Accra. But illegal mining is also a major source of employment. More than a million Ghanaians make their living from galamsey.

We hear from local galamsey miners and look at the negative impact this industry is having on both the workers in terms of health, the environment, and the wider community.

Advent calendars have evolved from the simple cardboard doors or chocolate treats to a multimillion-dollar premium industry; with major companies using them as a powerful brand awareness tool.

We find out why the design of an advent calendar is more important than ever, with many retailers investing in appearance and reusability; and we hear from environmental groups who are still concerned about the amount of waste.

Plus - are the products in these more extravagant calendars actually worth the money?
