评语："What's the Right Diet for You? A Horizon Special - Episode 1" 12 January 2015 00x85 The first of a three-part special in which Dr Chris van Tulleken, clinical psychologist Tanya Byron and nutrition and weight-loss scientists from Oxford and Cambridge universities put one of the latest theories on diets to the test. They have selected 75 overweight people from across the UK, who will be put on personalised regimens to explore overeating related to genes, gut hormones and emotions. The opening programme follows the volunteers as they undergo an intensive five-day analysis at a residential diet lab at Liverpool Hope University, before they are then put on the diets the experts believe are best-suited to them. "What's the Right Diet for You? A Horizon Special - Episode 2" 13 January 2015 00x86 In the second of three programmes, the volunteers leave the lab and take their diets home, where they face the challenge of sticking to their weight-loss plans while dealing with all the stresses and temptations of their real lives. Geneticist Giles Yeo uses eye-tracking technology to investigate how the Constant Cravers are affected by their 'hungry genes', while Tanya Byron visits Cambridge University to discover what happens in the brains of Emotional Eaters to compel them to comfort eat. The Feasters are brought together for a test by Fiona Gribble, who wants to find out why soup is such a great dieting tool. "What's the Right Diet for You? A Horizon Special - Episode 3" 14 January 2015 00x87 This programme looks into how physiological processes in the body and the brain can make the final weeks and months of a diet difficult. Fiona Gribble runs an experiment to show that the rate at which the Feasters eat their food affects how full they feel, Giles Yeo demonstrates how eating breakfast can help the Constant Cravers, and Paul Aveyard demonstrates ways that will help the Emotional Eaters learn how to deal with occasional indulgences and avoid further relapse. Lastly, the final results of the study are announced, revealing how successful the diet personalisation approach has been for the group and how many of the volunteers made their five per cent weight-loss target.

评语："Cat Watch 2014: The New Horizon Experiment: A Cat's Eye View" 7 October 2014 00x82 Millions of people have cats in their homes, yet they know very little about them. Are they playful pets, fearsome fighters or deadly hunters? In this three-part programme, Liz Bonnin joins forces with some of the world's leading feline experts to conduct a groundbreaking scientific study using GPS trackers and mini-cameras to follow 100 cats in three very different environments to find out what they get up to when they leave the house. The first edition examines how cats see, hear and smell the world with the senses developed by their wild ancestors, and looks at why this could be making life difficult for them in the modern world. "Cat Watch 2014: The New Horizon Experiment: The Lion in Your Lap" 8 October 2014 00x83 The second programme of the three-part scientific study reveals the wild side of domestic cats, with GPS trackers and mini-cameras showing how they transform from pet to predator as soon as they leave the house. Liz Bonnin and the team of experts put Ozzy and Smudge under surveillance to find out who's king of the street, and explain why cats' hunting instincts cannot be kept under control. "Cat Watch 2014: The New Horizon Experiment: Cat Talk" 9 October 2014 00x84 In the final episode of this three-part scientific study, Liz Bonnin and the team examine the secret language of cats, revealing the surprising conversations they have when their owners are asleep, and investigating why they meow to humans but not one another. They rig a house with cameras and trackers to discover if four cats residing under one roof can all get on and find out why living alongside people is making things difficult for 21st-century felines.

评语："Comet of the Century: A Horizon Special" 23 November 2013 00x81 Comet Ison is due to make its closest approach to the sun on 28 November and will be visible in both the evening and morning skies during December if it survives its brush with the star. The programme examines how Ison's tail of vaporised gas and water could give insights into some of the greatest mysteries of science, including the origin of the solar system and whether Earth's water came from similar celestial objects.

评语："Sex: A Horizon Guide" 11 September 2013 00x78 Professor Alice Roberts investigates how science came to understand sex - a simple word for a very complex set of desires, including individual passions, wants and emotions.
