Our hard-wired stress response is designed to gives us the quick burst of heightened alertness and energy needed to perform our best. But stress isn’t all good. When activated too long or too often, stress can damage virtually every part of our body. Sharon Horesh Bergquist gives us a look at what goes on inside our body when we are chronically stressed.

For every pound we spend on food shopping, 77p goes to the supermarkets, giving them a huge influence over what we eat. But can we trust the supermarkets to tell us the truth about what we are buying and how it was produced? Or do their profits come first? In an experiment to discover the hidden truths about our everyday foods, Horizon has built the first ever truly 'honest supermarket'. Drawing on the latest scientific research and leading experts from across the UK, the team have built a supermarket where the products are labelled with the real story of how they are produced and their effect on us and the environment. We invite the British public to come in and discover the truth about their favourite foods. And in our on-site lab, new scientific discoveries reveal the food facts the supermarkets aren't telling you. Presented by Dr Hannah Fry and dietician Priya Tew, The Honest Supermarket takes a cold hard look at what's really going on with the food we eat. From new research that reveals you're likely to be ingesting plastic particles along with your bottled water to the lab tests that uncover the disturbing truth about just how old your 'fresh' supermarket fish really is… You'll never look at the food on your supermarket shelves in the same way again.

Dr Chris Van Tulleken calls on the British public to seek out the truth about the top-selling over-the-counter medicines. We spend an astonishing 2.3 billion pounds on pills, potions and lotions from the chemist's shop every year to beat common ailments from headaches to colds to indigestion. But how much do we really know about what we're buying?

It’s 4am, and the big test is in 8 hours. You’ve been studying for days, but you still don’t feel ready. Should you drink another cup of coffee and spend the next few hours cramming? Or should you go to sleep? Shai Marcu defends the latter option, showing how sleep restructures your brain in a way that’s crucial for how our memory works.

Our lifespan is increasing by 2.5 years every decade - and a third of all babies born today can expect to live to 100. But living longer can come at a cost. Old age itself brings with it a range of debilitating illnesses, many of which are the result of accumulating damage during our lifetime. Three diseases in particular have become the main killers in the developed world - cancer, heart disease and dementia. But a revolution in bio-medicine is now offering new hope for the treatment of these ailments, and the potential to extend our lives still further. Methods such as gene editing and stem cell therapies are transforming the way medicine can conquer disease today. These extreme frontiers of medicine do, however, also come with a range of ethical dilemmas - when is the right time to try out an experimental technique on a patient? Should we gene edit human embryos? And is it right to use cells from aborted foetuses for medical treatments?
