Last month saw the hottest June on record – and, while July has seen heavy downpours in the UK, much of Europe and the US experienced life-threatening heatwaves.

As things heat up, aquifers shrivel – and London’s 90-day supply of water means the city is never far from its taps running dry. That’s Day Zero: a benchmark that several cities around the world have come alarmingly close to – or, in some cases, even reached – in the last decade. But what happens when that day comes?

In today’s episode we speak to Professor Priti Parikh, infrastructure engineer at University College London, about the looming threat of Day Zero and how household tricks all the way national innovations can offer promising solutions.

Would you call yourself a bit of a hugger? Or does the mere thought of a stranger brushing past you in a cafe make your skin crawl? When it comes to being touched, we all have our own attitudes and opinions. But what can science tell us about this understudied and often misunderstood sense?

In this episode we catch up with Prof Michael Banissy, a social neuroscientist based at Goldsmiths University in London and author of the new book When we Touch.

For many, working only four days a week – and enjoying a longer weekend – might sound like a pipe dream: However, some workplaces are now experimenting with just that. 61 UK companies recently piloted a four-day workweek, with above 90 per cent of them continuing the scheme after the six-month trial.

What impact does a four-day workweek have on a person’s productivity, mental health and physical wellbeing? And are there many drawbacks to working less? To answer this and much more, we’re joined by Alex Pang, productivity researcher, author of Work Less, Do More and programme director at non-profit organisation 4 Day Week Global.

Even before the global COVID pandemic, simple mention of the word ‘virus’ was likely to send shivers down most of our spines. But it turns out not all viruses are nasties. Ever heard of a phage? They are a type of virus that infect bacteria. Despite being one of the most common forms of life on Earth we still only know very little about them. However, current research suggests they may just be one of our greatest allies in the fight against superbugs.

As the UK builds more nuclear reactors, there is an increasing pressure to find somewhere to put the waste. But what actually is nuclear waste? Does it actually look like a bright green sludge? Where does currently go? To answer these questions I’m joined by Dr Lewis Blackburn, nuclear materials scientist at the University of Sheffield. He talks about the incredible research going into sealing, burying and locking away nuclear waste, the relationship between nuclear and space (and why we can’t just fire off our nuclear waste on a rocket), and the vast timescales when it comes to nuclear waste that go beyond human lives, including the people working on them.
