Is the "always on" culture of work emails and messaging destroying our health? Should we have a legal right to switch off, like in France?

Manuela Saragosa explores the world of office Whatsapp groups and the blurring work-life balance, with Professor Mark Cropley of Surrey University, occupational health psychologist Gail Kinman of Bedfordshire University, and Ellen Temperton of solicitors Lewis Silkin. Plus entrepreneur Mitul Thobhani explains why at his tech company Baytree Labs he doesn't impose any division between work and home life at all.

Could drone technology solve our urban transport needs? Ed Butler explores the new generation of flying cars developers hope will be ferrying commuters around major cities in the next few years. Steven Tibbitts, chief executive of Zeva Aero, and Eric Bartsch of start-up VerdeGo Aero, give the sales pitch. Steve Wright, associate professor in aerospace engineering at the University of the West of England in the UK, gives the reality check.

When governments need to raise money, they promise a reward in return for your investment. But how much - or how little - they're promising says a lot about the country, and if investors perceive it as risky to invest in or not. But why are analysts so obsessed over something called the bond yield curve? Pippa Malmgren, policy analyst, says at the moment there's nothing to be afraid of from what the curve tells us. Russ Mould from AJ Bell on the other hand says we should be careful. We try to make sense of this confusing curve.

Overrun by bots and identity thieves, does the worldwide web need a fundamental overhaul?

Ed Butler reports from the Future in Review tech conference in Utah, where he speaks to two entrepreneurs offering partial solutions. Denise Hayman-Loa's firm Carii offers corporations safe spaces for secure online collaboration, while Steve Shillingford's Anonyome Labs helps citizens keep their personal data secret when active online.

But do such solutions go far enough, or does the internet a complete redesign? Ed speaks to one of its original architects, Larry Smarr of the California Institute for Telecommunications and Information Technology, as well as Berit Anderson, founder of the future tech media company Scout.

Why has there been so little political fall-out from allegations by the New York Times that the US President and his family dodged hundreds of millions of dollars in tax, in some cases through outright fraud?

Manuela Saragosa speaks to Susanne Craig - one of the journalists making the claims after 18 months of painstaking research. Yet the US public remains unmoved. Bloomberg editor John Authers fears for what that says about the breakdown in trust in modern Western society.

Plus Pippa Malmgren, a former advisor to President George W Bush, explains why she thinks the tax investigation may represent a bigger threat to Donald Trump than the much-reported Mueller investigation.

The private sector is muscling in on space exploration, and the biggest commercial opportunity could be tourism.

Ed Butler meets the star-gazers at the Future in Review conference of tech entrepreneurs in Utah. Ariel Ekblaw, who founded the Space Exploration Initiative at MIT, discusses the logic of self-assembling space hotels. Nasa chief scientist Dennis Bushnell talks cosmic beach combing.

And Chris Lewicki, head of space mining start-up Planetary Resources, explains why he thinks it makes more sense to mine water on asteroids than bring it with us from Earth.

Are new forms of 'artificial' meat about to change the food industry? Regan Morris goes to California to taste a chicken nugget its makers hope will be on restaurant menus by the end of this year. Josh Tetrick is the boss of Just - the company behind it. She also hears from Mark Post, the maker of the first lab-grown burger, and Tom Mastrobuoni from Tyson Ventures, the meat processing company that wants to be the world's largest 'protein' company. That's fine but just don't call it "meat" says Lia Biondo from the US Cattlemen's Association.

Does STEM still have a problem with women? Manuela Saragosa speaks to Dr Jess Wade, a physicist at Imperial College in London, and soil microbial ecologist Kelly Ramirez, co-founder of 500 Women Scientists. Rebekah Higgitt, a lecturer in history of science at the University of Kent in the UK, explains the marginalisation of women in science.

Tsunamis, earthquakes and a sinking capital - not all of Indonesia's problems are down to Mother Nature.

Jonathan Bithrey reports from this blighted archipelago on the Pacific ring of fire. 14 years after the Indian Ocean tsunami, why was the country so ill-prepared for the tidal wave that hit Palu this week? And what is being done to stop Jakarta slowly sinking into the sea under the weight of poor planning and overdevelopment?

Whatever the fate of the heavily indebted Tesla Motors, is the electric vehicle revolution now set to sweep the world? And despite his Twitter antics and legal problems, has the company's chief executive earned the right to be brash?
