The Mysteries of the Octopus, with Prof David Scheel Jul 13, 2023

Show notes

Octopuses are surely one of the most unusual animals on Earth. They have eight limbs, three hearts, a doughnut-shaped brain and bleed blue blood. It’s little wonder, then, that they have inspired awe and curiosity in everyone from artists and filmmakers to biologists and science fiction writers.

In this episode we catch up David Scheel, professor of marine biology at Alaska Pacific University. He tells us what he has learned in his 25 years of studying these fascinating animals, and what new discoveries he made when writing his book, Many Things Under a Rock: The Mysteries of Octopuses.

Why touch is our most misunderstood sense, with Prof Michael Banissy Jul 09, 2023

Show notes

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.

He tells us all about the fascinating discoveries he has made about everything from the effects of mother’s skin-to-skin contact on a new born’s growth and development to the boost in performance sports team’s get when they regularly hit high fives.

The argument for a four-day workweek, with Alex Pang Jul 02, 2023

Show notes

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.

The intriguing science of phages, with Tom Ireland Jun 29, 2023

Show notes

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.

The race to bury nuclear waste in hidden bunkers, with Lewis Blackburn Jun 25, 2023

Show notes

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.

How mental imagery training could boost your motivation, with Dr Jon Rhodes Jun 22, 2023

Show notes

Whether your goal is mastering a new skill or losing weight, you’ll know the importance of motivation and effective planning. And one intriguing new field of psychology called Functional imagery training may help here.

As an increasing number of compelling studies show, vividly visualising attaining your goal and the road bumps along the way could leave you better motivated when setbacks occur. That’s why functional imagery training is now being used by athletes and the military.

How does it work? And how promising are the results? We speak to Dr Jon Rhodes, lecturer in psychology at the University of Plymouth, to find out.

The fascinating chemistry of fermentation, with Andrea Sella Jun 18, 2023

Show notes

From kimchi to kombucha to kefir, you’ve probably noticed that fermented foods are trendy right now. They appeal to the daring, but also to people who may not even know they are eating fermented foods when they enjoy their beer, bread, and cheese. In fact, these fermented goodies have actually been around for hundreds of years – but what actually are they, and why do we like them?

This week, I’m joined by Andrea Sella – a professor of chemistry at University College London and a keen fermenter. Speaking to Andrea behind the scenes of the Cheltenham Science Festival, we discussed the importance of sugars to creating and digesting food, why and how we overcome disgust responses to get pleasure out of fermented foods, and how new fermentation techniques could help us lower our greenhouse gas emissions – along with some chemist’s tips for creating delicious fermented meals.

The psychology of why we feel ghostly presences, with Ben Alderson-Day Jun 11, 2023

Show notes

At our core, humans are deeply curious about the unknown – and ghostly spirits are no exception. From Hamlet to The Sixth Sense to Ghostbusters, the excitement or horror of encountering ghosts or spirits is ingrained in the human imagination. But for many people it’s very real: for people who feel someone’s presence who isn’t there, or see someone or something, or hear voices.

In this episode of Instant Genius, we spoke to psychologist Ben Alderson-Day ahead of the Cheltenham Science Festival about why some of us believe in ghosts, science mediums and psychological disorders, and what makes someone more likely to feel presences.
