Over a person's lifetime they are likely to be prescribed more than 14,000 pills. Antibiotics, cholesterol lowering tablets, anti-depressants, painkillers, even tablets to extend youth and improve performance in bed. These drugs perform minor miracles day after day, but how much is really known about them? Drug discovery often owes as much to serendipity as to science, and that means much is learnt about how medicines work, or even what they do, when they're taken. By investigating some of the most popular pills people pop, Horizon asks, how much can they be trusted to do what they are supposed to?

Horizon explores the strange and wonderful world of illusions – and reveals the tricks they play on our senses and why they fool us. We show how easy it is to trick your sense of taste by changing the colours of food and drink, explain how what you see can change what you hear, and see just how unreliable our sense of colour can be. But all this trickery has a serious purpose. It’s helping scientists to create a new understanding of how our senses work – not as individual senses, but connected together. It holds the intriguing possibility that one sense could be mapped into another.

Born in Groot-Zundert, The Netherlands, Van Gogh spent his early life as an art dealer, teacher and preacher in England, Holland and Belgium. His period as an artist began in 1881 when he chose to study art in Brussels, starting with watercolours and moving quickly on to oils. The French countryside was a major influence on his life and his early work was dominated by sombre, earthy colours depicting peasant workers, the most famous of which is The Potato Eaters, 1885. It was during Van Gogh's studies in Paris (1886-8) that he developed the individual style of brushwork and use of colour that made his name. In 1888 he moved to Arles where the Provençal landscape provided his best-known subject matter. However, it also marked the start of his mental crisis following an argument with his contemporary Paul Gauguin. Van Gogh was committed to a mental asylum in 1889 where he continued to paint, but he committed suicide in 1890.

The Obama Deception is a hard-hitting film that completely destroys the myth that Barack Obama is working for the best interests of the American people. The Obama phenomenon is a hoax carefully crafted by the captains of the New World Order. He is being pushed as savior in an attempt to con the American people into accepting global slavery.

In this programme, Mary descends into the city streets to discover the dirt, crime, sex and slum conditions in the world's first high-rise city. This Rome is not the marble Rome we know, but a vast, messy metropolis with little urban planning, where most Romans lived in high-rise apartment blocks with little space, light, or even sanitation. Forced outdoors into the city streets, she reveals where they went to hang out, get drunk, have sex and get clean. She looks at the Forum as a place of gamblers, dentists and thieves, and she explores the lustiness of Roman bar life and jokes. Finally, exploring law and order from the bottom up, Mary examines how this city really worked. She meets Ancarenus Nothus, an apartment dweller who lived in fear of the rent collector; Notorious Primus, who wrote about his three great pleasures in life - baths, wine and sex; and Unlucky Doris, a seven-year-old girl killed in one of Rome's many fires.
