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.

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.
