  • Building a Healthier Britain - 02 Fluoride

  • Radio 4

Adding fluoride to the water supply has always been a polarised debate. Some think it will prevent tooth decay while others say its safety has not been proven. Its not a new argument, 50 years of fluoridation studies are available but recently public health officials of both Scotland and England have revisited the issue. The difference is that Scotland has decided against increasing the amount of fluoride in the water, while in England the Strategic Health Authorities can, after consultation, request that Water Companies add fluoride to an agreed level. Richard Hannaford asks whether science can ever solve this controversy.

  • The Lopsided Universe - Life Through the Looking Glass

  • Frank Close

There's an ass in mythology that stood equidistant between two bunches of carrots. One on its left, the other on its right side. The ass, unable to choose between left and right, starved to death. Luckily for us, life made a decision and didn't perish like Buridan's ass. The molecules that make living things are all handed. What's more they all have the same handedness - but why? Frank Close finds out how a French chemist found the clue to this conundrum at the bottom of a glass of wine a hundred and fifty years ago.

  • Botany: A Blooming History: Hidden World

  • BBC 4

For 10,000 years or more, humans created new plant varieties for food by trial and error and a touch of serendipity. Then 150 years ago, a new era began. Pioneer botanists unlocked the patterns found in different types of plants and opened the door to a new branch of science - plant genetics. They discovered what controlled the random colours of snapdragon petals and the strange colours found in wild maize.

  • Botany: A Blooming History: Photosynthesis

  • BBC 4

The air we breathe, and all the food we eat, is created from water, sunlight, carbon dioxide and a few minerals. That\'s it, nothing else. It sounds simple, but this process is one of the most fascinating and complicated in all of science. Without it there could be no life on earth. It\'s that important.

  • Chemistry: A Volatile History : The Order of the Elements

  • BBC

In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists\' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry\'s most beautiful intellectual creations - the periodic table.

The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?

It's the process that powers the Sun, and scientists know that if they could just make nuclear fusion happen here on Earth they could solve all the world's energy problems. Billions of dollars have been spent on trying to make it happen, but now an American scientist claims to have created nuclear fusion simply by bombarding a flask of liquid with sound waves. Many scientists refuse to believe his claims, so Horizon has assembled a team to replicate the experiment. This film reveals the team's findings
