Sliced Bread BBC Radio 4

What's the best - and most humane - way to get rid of pests?
For some of us Tom and Jerry might be the sum total of our knowledge of the struggle between domestic life and unwanted rodents. But for listeners Colin and Mary, things are getting much more real! Colin wants to know if the plug-in devices he's seen that promise to deter rats and mice using ultrasonic actually work. Mary has caught mice and then released them back into the wild in nearby woodland, believing it's the more humane way to deal with the problem. But is it?
With the help of Natalie Bungay from the British Pest Control Association and Rob Young, Professor of Wildlife Conservation at the University of Salford, Greg Foot sets out to find the answers, hoping to nibble at the metaphorical cheese without getting caught in the figurative trap (or something).
All of the ideas for our investigations come from you, our listeners, and we're always on the lookout for more.

Listener Jennifer is considering switching contact lenses, if there's an alternative that's more eco friendly. She's not alone - we've had lots of questions about eyecare options, and whether the fancy features some lenses offer are worth the extra cash. Joining Greg and Jennifer in the studio to talk all things contact lens are Daniel Hardiman-McCartney, a clinical adviser to the College of Optometrists, and Sarah Smith - a research optometrist who's studied the environmental impact of these tiny pieces of plastic.

Is it worth paying more for premium car tyres?
There's a huge range of car tyres to choose from and the price differences between them can be significant. So do you really need to pay more to get a good tyre?
Listener Ian runs a car maintenance business and wants to know if the budget tyres he's been fitting are the right choice. Will they last as long and be just as safe? What do the different ratings on the labels you can see online mean? And as he moves towards electric cars he's also keen to know whether they need a special sort of tyre.
With the help of two experts in the field, Greg Foot 'treads' through the studies and the science to find out more. It's how he rolls (we'll stop now).

Lots of different types of period products claim to be eco friendly, from menstrual cups to period pants and reusable pads. But how do their environmental credentials stack up? That's what listener Sam wants to know - and she's not the only one asking about not just the impact of these so called sustainable period products on planetary health, but also on women's health too. Joining Sam and Greg for this one are Natalie Fee, founder of the non profit City to Sea, who campaigns for "plastic-free periods", and Dr Nicola Tempest, a senior lecturer in gynaecology at Liverpool University.

The UK market for air care products is expected to grow to £674 million this year - and for this episode, we're investigating just how these products tackle bad smells in our homes. Can air fresheners really "eliminate" stinky odours with science, or do they just smell nicer? And what does using them do for our air quality? That's what listener Conor from Manchester wants to know. He joins Greg in the studio, alongside two experts - Nicola Carslaw, a professor in indoor air chemistry‘ at the University of York, and emeritus professor of chemo-reception at the University of Manchester, Krishna Persaud.

Is an LED face mask the secret to brighter, clearer, more youthful skin?
Greg Foot is back with a new series of Sliced Bread to run a whole new batch of your suggested wonder products through the evidence mill. From car tyres to contact lenses, air fresheners to LED face masks, Greg will separate science fact from marketing fiction as he investigates whether each product is 'the best thing since sliced bread' or 'marketing BS'.
There's a slightly new sound to this new series: having recorded most of the previous episodes remotely, Greg is going to be joined in the studio by the listener and experts to investigate the wonder products together!
First to join Greg is Helen Leneghan from County Down. She’s seen LED Face Masks all over social media and wants to know if they actually work. Do they reduce your wrinkles? Will they give you a radiant glow? And can they help with some skin conditions like acne or rosacea?
