In this month's Cafe Scientifique, Dr Luke Clarke from the University of Cambridge explores the effect gambling has on our brain. He reveals why gambling is so addictive, how 'near-misses' make us gamble more and how gambling stimulates the same pleasure centres in our brains as chocolate and sex! We also answer audience questions including why gambling on the lottery seems less risky, whether there are differences between regular and internet gambling, and whether there are differences in addiction between men and women.

This month we enter the clinic to discover how clinicians at hospitals across the UK are using Diamond to investigate a variety of medical concerns. We discover why some women may be prone to pre-term labour, and why metal-on-metal hip replacements cause inflammation in some patients and not others. Plus, we've got the the latest news and events from Diamond! Like this podcast? Please help us by supporting the Naked Scientists

In this months Cafe Scientifique Dr Giles Yo from the Institute of Metabolic Research at the University of Cambridge askes the question: Are my genes to blame when my Jeans don't fit?. He explores the behind our metabolism and fat storage and asks if these play a more crucial role than our environment in determining our weight. We also answer audience questions that reveal how our weight may also be affected by what happens when we're in the womb and how twin studies are crucial in understanding the role of our genes. Plus, we give you a heads up on what to expect at next months event! Like this podcast? Please help us by supporting the Naked Scientists

In this podcast from the March Cafe Scientifique in Cambridge, we investigate how our brain takes shortcuts to understand the world around us and how it jumps to delusions! We meet event speaker Dr Paul Fletcher to find out how our brains process the masses of information coming in from the world around us by using shortcuts and how changes in these shortcuts can lead to delusions . We also answer your questions such as what the scale of these delusions are and whether knowing this about our brains means eye witness accounts are less reliable. All that plus a heads up on what to look forward... Like this podcast? Please help us by supporting the Naked Scientists

In this podcast from the February Cafe Scientifique in Cambridge, we look out deep into our universe to investigate our place in the cosmos. We meet event speaker Dr Carolin Crawford to find out how astronomers look out into our universe and what they understand about our stars and galaxies so far. We also answer your questions such as how we much of our universe we can see, what dark matter and dark energy are, and we also investigate the likeliness of other life out in space!
