If, like CrowdScience listener Lili, you enjoy working out in the gym, you may have wondered where your fat disappears to when you exercise?

The short answer is that we convert it to energy that powers a whole range of physical processes, from breathing to walking as well as lying down and doing nothing. But the science behind energy expenditure is a little more complicated.

Presenter Anand Jagatia jumps on an exercise bike to have his metabolism measured and learns that he may be relying on an entirely different source of fuel as he works up a sweat.

Is all that hard work worth the effort it involves? Recent research suggests there is a limit to the number of calories humans can burn and that engaging in physical activity is not always a sure-fire way to keep trim.

So if working out is not the best way to lose weight, how about harnessing our own fat to tackle the complications of obesity? It used to be thought brown fat was exclusive to babies (and bears) but we now know adults have some of it too. Anand discovers that it appears to play a vital role in combatting a range of chronic diseases including hypertension and diabetes.

In 1944, Doreen Page was studying German at London university. When her call up papers came through, language skills were in high demand and she was snapped up to be a German interpreter at Bletchley Park. She worked in ‘Hut 8’.

Discover the story behind the recently discovered only known wartime film footage of a secret site connected to Bletchley Park.

A silent film, recently donated to Bletchley Park Trust, is believed to be a compilation of footage recorded between 1939 – 1945, showing members of MI6 Section VIII at Whaddon Hall, Buckinghamshire. During World War Two, this was a most secret site where Ultra intelligence produced by the Government Code and Cypher School (GC&CS) at Bletchley Park would be sent, and then passed on to Allied commanders in the field.

In this mini-documentary, hear Bletchley Park Veteran, Geoffery Pidgeon who worked in MI6 Section VIII during WW2, recall how it felt to watch the film for the first time and recognise his father. Peronel Craddock, Bletchley Park’s Head of Collections and Exhibitions and Dr. David Kenyon, Research Historian at Bletchley Park also talk about why the discovery of this film is so important.

About Bletchley Park

Bletchley Park is a vibrant heritage attraction and museum, open daily to visitors.

It was the home of British World War Two codebreaking; a place where technological innovation and human endeavour came together to make groundbreaking achievements that have helped shape the world we live in today.

This unique site was previously a vast Victorian estate, where parts including the Mansion still survive, expanding during wartime to accommodate Codebreakers Huts and Blocks.

During World War Two, the Government Code and Cypher School (GC&CS), now known as the Government Communications Headquarters (GCHQ), was based at Bletchley Park. It grew from a small team of specialists to a vast intelligence factory of thousands of dedicated women and men. This extraordinary combination of brilliant and determined people and cutting-edge technology contributed significantly to Allied victory. In tough conditions, they provided vital intelligence and developed pioneering technological innovation that had a direct and profound influence on the outcome of the war.

The site continues to reveal secrets and tell fascinating stories of our national legacy.

The Bletchley Park Trust

Bletchley Park Trust is a registered charity, heritage attraction and independent museum. As an independent charity, we rely on income from our visitors, Friends and supporters to secure the long-term future of the site.
