Wild Inside returns for a new series to take a look at some of our planet’s most exceptional and unusual creatures from an entirely new perspective: the inside. Whilst we can learn a lot from observing the outside, the secrets to the success of any animal – whether they swim, fly, or hop – lies in their complex internal anatomy. How do these wild animals survive and thrive in harsh and changing environments? To truly understand we need to delve inside.

Professor Ben Garrod, evolutionary biologist from the University of East Anglia, and expert veterinary surgeon Dr Jess French, open up and investigate what makes each of these animals unique, in terms of their extraordinary anatomy, behaviour and their evolutionary history. Along the way, they reveal some unique adaptations which give each species a leg (or claw) up in surviving in the big, wild world.

The series begins with an icon of the outback – known best for its hopping, boxing, and cosy pouch – the red kangaroo. Despite the immense heat and lack of water, these marsupials dominate Australia, with their evolutionary history driving them to success. From the powerful legs which allow them to hop up to 40km an hour, to an unexpected reproductive system that keeps their populations plentiful, Ben, Jess and marsupial expert Dr Jack Ashby reveal a mammalian anatomy which holds many surprises.

Hannah Fry explores two tales of data and discovery.

A young researcher gains access to a secretive data set and discovers a system causing harm to the very people it is supposed to help.

One day a student makes a discovery which, if true, could shake the intellectual foundations of a global movement, and undermine politicians around the world.

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.

Hannah Fry explores two more tales of data and discovery.

Gossip and rumour are plaguing a tile manufacturing company. The chatter is pulling morale to new lows, and amid it all, a question hangs in the air: who is spreading it? Can the science of networks find out?

And, what is the secret to ageing well? One man believes he may have found the beginnings of an answer, and it is hiding in a convent.
