Horizon is BBC Two's flagship 50-minute science documentary series. In September 2004 it celebrated its 40th anniversary and it continues to enjoy outstanding critical acclaim. Recognised as the world leader in its field, it regularly wins a sweep of international science, medical and environmental film accolades, and has recently won the Royal Television Society Award and the Prix Italia. In 2002, the British Academy of Film & Television Arts presented Horizon with the BAFTA Television Award for Best Factual Series or Strand. In 2003 it won the prestigious Images et Science award for best medical documentary and the Carl von Linne Award at the Living Europe film festival in Sweden. That year, a Horizon co-production with WGBH Boston won the Emmy for best documentary.

M Theory for Dummies

Horizon plunges down the biggest rabbit-hole in history in search of the smallest thing in the Universe. 　　It is a journey where things don't just become smaller but also a whole lot weirder. Scientists hope to catch a glimpse of miniature black holes, multiple dimensions and even parallel Universes. As they start to explore this wonderland, where nothing is quite what it seems, they may have to rewrite the fundamental laws of time and space.

Horizon: The Truth About Looking Young Plastic surgeon Dr Rozina Ali leaves the operating theatre behind for the frontiers of skin science and asks if it is possible to make your skin look younger without surgery. She discovers the latest research about how the foods we eat can protect our skin from damage, and how a chemical found in a squid's eye is at the forefront of a new sun protection cream. She also finds out how sugar in our blood can make us look older, and explores an exciting new science called glycobiology, which promises a breakthrough in making us look younger.
