"Could you make a machine to make it rain in minutes?" asks listener Alexander from Hampshire, aged 12. For this series, with lockdown learning in mind, Drs Rutherford and Fry are investigating scientific mysteries for students of all ages. Rutherford and Fry dive into the clouded story of weather modification.

First, we need to decide where and when we might deploy any rain machine. Liz Bentley, Chief Executive of the Royal Meteorological society, takes us through the science, maths and art of predicting the weather. Hannah heads down to the BBC Weather Centre to meet meteorologist Helen Willetts, who takes us through the highs and lows of forecasting.

And then for the technology itself. Mark Miodownik, scientist and author of Liquid: The Delightful and Dangerous Substances The Flow Through Our Lives, reveals that a technique called cloud seeding has almost certainly been tried in different places around the world for decades. But, whilst it’s supposed to induce showers and even clear the way for sunny spells, the results aren’t always reliable. And even if we can make it rain, Liz explains why messing with the weather may be at our peril.

The Evidence: The science of the menopause

Millions of women around the world experience the menopause each year; it’s an important milestone, which marks the end of their reproductive years.

But every individual's experience of it is personal and unique. In some cultures, there's a stigma about this life stage – it's viewed with trepidation and as something to be dreaded. In other cultures, it's considered to be a fresh start - a time of greater freedom when women no longer have to worry about their menstrual cycles.

In this edition, recorded at Northern Ireland Science Festival in Belfast, Claudia Hammond and her expert panel take a global look at the science of the menopause and debunk some myths along the way.

As Claudia and her guests navigate their way through the menopause maze, they look at the most recent academic research in this area. They also discuss the physical and psychological symptoms, the lifestyle changes women can make and the different treatments available, including Hormone Replacement Therapy.

Claudia also speaks to the American biological anthropologist who has dedicated an impressive 35 years of her life to studying the average age of the menopause in different countries - and finds out how hot flushes vary in different cultures. She also speaks to a doctor who is working hard to make women’s health less of a taboo subject in the community where she works. And she hears from a Professor of Reproductive Science who is setting up the UK's first menopause school.
