Climate change has shot up the current political agenda in part due to the Extinction Rebellion protests. An urgent question now facing UK policymakers is whether they should accelerate the adoption of cutting-edge green energy technology to curb the country's carbon emissions. But are there dangers of being an early adopter of new technology? What happens if it doesn't work or if it's outpaced by newer technologies which are cheaper and more efficient? The BBC's Business Editor, Simon Jack, investigates.
The Real Gender Pay Gap
Women are paid less than men and do more unpaid work. The gender pay gap doubles after women become mothers. Female-dominated professions tend to be lower-paid than male-dominated ones. What's going on and can we fix it?

Maintenance is an unfashionable word. But as Chris Bowlby discovers, keeping our infrastructure in good condition is one of the most crucial and creative challenges we face. Key assets such as concrete bridges built in the early post-war decades are crumbling, and may be what one expert calls 'ticking time bombs'. And all kinds of systems, even in the digital world, still need maintaining well. But all the focus for politicians and many engineers is on brand new infrastructure, not sustaining the vital assets we already have. So how can we learn to value maintenance in a radical new way?

Love Island, dating apps and the politics of desire
For centuries we have met our other halves through family, friends, work, or religious institutions. But they have all now been outstripped: meeting online is now the most common way to meet. Not long ago, finding love online was considered unconventional. Now the ping of dating apps is the soundtrack to many people's lives.
But what does this change mean for how we choose whom to date?
Shahidha Bari, author and academic at Queen Mary University of London, examines the changing landscape of modern love - its dating apps, its politics of sexual preference - and ultimately tries to answer the age-old question: what does Love Island tell us about love?

Will China and America go to war?
Will the growing competition between China and the United States inevitably lead to military conflict? One leading American academic created huge attention when in 2017 he posed the idea of what he called a "Thucydides Trap". Drawing on the work of the ancient Greek historian, he warned that when a rising power (Sparta) threatens an existing power (Athens) they are destined to clash, unless both countries change their policies. He warned that the same pattern could play out with the US and China. Since then, President Trump has engaged in combative rhetoric over trade, while China has fast been modernising and upgrading its military. BBC Diplomatic Correspondent Jonathan Marcus considers whether Washington and Beijing can escape the trap - or whether the growing economic, strategic and technological rivalry between the two nations will inevitably end in conflict.
