   Which weather app is the most accurate? Lees meer

   Listener Owen keeps running into a problem: he's not sure which weather forecasting app to trust. He and his partner each use different weather apps on their phone, and find they often predict different things.

   Owen wants to know once and for all - which app should he trust, and why?

   To find out, Greg Foot is joined by with meterologist Dr Rob Thompson from the University of Reading.

   Which eye drops are best for dry eyes? Lees meer

   Listener Carole wakes up each morning with dry, gummed-up eyes. As a result she's built up a small hoard of different eye drops, variously promising to hydrate, soothe, or relieve; and that's only a fraction of the many drops, vials, and ointments out there on the pharmacy shelves. Carole's seen some brands come with premium prices, and others promise to be "preservative-free". She wants to know: are any of them the best thing since sliced bread?

   To find out, Greg Foot is joined by consultant corneal and cataract surgeon Bita Manzouri and research optometrist at Aston University Dr Sònia Travé Huarte.

   Can mushroom gummies really sharpen your mind, reduce stress, and boost your energy? Lees meer

   Listener Daisy has been seeing adverts for mushroom gummies all over her Instagram. These aren't the psychedelic kind of mushrooms - instead they're gummy sweets containing so-called 'functional mushrooms' such as lion's mane and reishi. The companies promise that taking just two a day will provide all sorts of beneficial effects, and some online posts even hint that they can address symptoms of perimenopause and menopause.

   But do they actually work?

   To find out, Greg Foot is joined by Dr. Nicholas Money, mycologist and science writer at Miami University in Ohio; and Dr. Helen Wall, GP and menopause specialist.
