Homebase was once one of our leading home improvement chains so, why did it have to close all of its stores?

The BBC Business journalist Sean Farrington investigates.

Alongside him is the entrepreneur Sam White, who at the end of the show has to reach her own conclusions, based only on what she has heard and her own business acumen.

Homebase was established by the supermarket chain Sainsbury's and a Belgian retailer which was already running a DIY business in Europe and America.

The first Homebase store opened in Croydon in 1981 and it had to be temporarily closed by the police after visiting crowds caused a traffic jam.

The chain expanded across the UK and had more than 300 stores.

It went through some highs, and some serious lows, with various owners but what ultimately caused the closure of its shops?

Sean and Sam hear from expert guests including:

- Allison Foster, curator of the Sainsbury Archive, which is based at London Museum Docklands

- Dave Elliott, a former Trading Director then later Commercial Director at Homebase under different owners

- Matt Walton, senior data analyst at GlobalData

While Homebase's standalone stores are toast, the brand continues to trade online under new ownership. Homebase garden centres and products are also being included within branches of The Range.

FHM was the men's magazine that sold vastly more copies than any of its competitors but still ended up toast. So, why did its publishers stop printing it while other men's magazines survived?

The BBC Business journalist, Sean Farrington, charts its highs and lows in the company of four of FHM's former editors.

Alongside them is the entrepreneur, Sam White, who has to use her business acumen to reach her own conclusions based upon what she has heard.

Featuring in the show are:

- Eric Musgrave - the original editor of 'For Him Magazine' as it was known when it launched in 1985

- Mike Soutar - the FHM editor who took sales to over half-a-million a month in the late 1990s

- Piers Hernu - FHM's editor-at-large who took to the airwaves to defend lads' mags against accusations of sexism

- Joe Barnes - who edited the magazine for four years until shortly before its print publication ceased

Can supplements claiming to make menopause symptoms more bearable, really help?

Going through menopause can result in a myriad of symptoms, leaving women stressed, exhausted, and desperate for anything that might make it easier to deal with.

In recent years, a huge range of products have become available in supermarkets, pharmacies and online, all promising to help alleviate some of these symptoms – for a price. So listener Susie, who said she felt she was experiencing some of these symptoms, got in touch with Sliced Bread, to ask if it might be money well spent?

Greg Foot drills down into the top ingredients of these supplements and their claims, alongside GP Dr Helen Wall who runs a Menopause Clinic in Greater Manchester. They look at what the science says, and ask if these supplements really can support women through the menopause?

Do Vagus Nerve Stimulators help your mental health?

The vagus nerve could be one of the most important body parts you might never have heard of. It's a large nerve that connects major organs like the heart and lungs to the brain and studies have found that stimulating it with electrical pulses can lead to dramatic improvements in some people with depression and other mental health conditions. Those trials were for medical devices implanted into the chest, but listener Karin has seen commercially available versions that you wear over your ear.

But do they work? Karin joins Greg in the studio along with leading experts in the field to do a deep-dive into the studies and separate out the science fact from the marketing fiction.

When staring at shelves full of sticks, tubs and tubes all promising us the perfect pout, how do you know which Lip Balms will really help keep chapped lips at bay?

Listener Kiran is a regular lip balm applier - saying she often suffers with dry or cracked lips, and recently splashed out on an expensive lip balm after seeing celebrity endorsed adverts for it online. But she isn’t sure it’s any better than her trusty tub of Vaseline.

To find out, Greg Foot speaks to Consultant Dermatologist and Dermatological Surgeon Dr Emma Craythorne about lips, lip lickers, mouth breathers and the causes of cracking - as well as lecturer in pharmaceutical and medicinal chemistry at the University of Sunderland, Dr Teresa Borrello about what is IN these lip balms to plump, smooth, or repair.

Which products are best for bedtime listening?

According to a YouGov poll nearly half of us listen to music or podcasts to help us get to sleep and there are a range of products designed to do just that.

Listener Nick has seen wearable sleep headbands with speakers woven in to the fabric which he hopes will stop him waking up in the middle of the night with headphones or earbuds digging into his ears.

And listener David says his social media is promoting sleep bars that go under the pillow and claim to transmit sound via bone conduction.

To find out more, Greg is joined by acoustic expert Professor Trevor Cox and Lecturer at the Surrey Sleep Research Centre, Ullrich Bartsch. They discuss the sound quality of these devices and whether it's a good idea to listen to music or podcasts at bedtime at all. Is there any evidence that it results in a good night's sleep?

You may have heard health warnings around too much red or processed meat, and considered trying a plant based meat alternative as one of your midweek meals instead. But after looking at the ingredients on the packet and spotting salt, additives and flavourings, wondered if they really are the healthier choice?

That’s exactly what listener Graham did, as he hunted for an alternative to his beloved sausage – and found that the plant based versions all seemed to be heavily processed. He's asking, are they really better for us? And are they better for the environment too?

Artificial sweeteners appeal to anyone with a sweet tooth looking to cut down on their sugar intake. They’re not only for use in our cups of tea or coffee, but they’re also in fizzy drinks, low calorie products, sweets and baked goods. But are they really a better alternative?

Greg is joined by a leading scientist from the World Health Organisation, as well as a Professor of Gastroenterology who has researched the impact of sweeteners to “spill the tea” on this topic. Can using them as an alternative help us reduce our blood sugar? Are all kinds of sweetener safe? And what about their effects on us long term?
