Jay Owens argues that dust is a lot more interesting than we think, and we ought to pay more attention to it.
Jay has spent years researching dust, and produces a popular newsletter on the subject. In this fascinating Four Thought, recorded at the Design Museum in London, she shares some stories from the field of dust research that up until now have only been known to other ‘dust people’, as she calls her fellow dust researchers.
Producer: Giles Edwards.
The castaway this week is James Burke, whose broadcasting style has been described as "turning science into show-biz". But, paradoxically, he admits to being immensely impractical and reveals to Michael Parkinson, while choosing his eight records to take to the island, that he at one time planned to make music his career.
Melvyn Bragg and guests discuss the origins, development and uses of chromatography. In its basic form, it is familiar to generations of schoolchildren who put a spot of ink at the bottom of a strip of paper, dip it in water and then watch the pigments spread upwards, revealing their separate colours. Chemists in the 19th Century started to find new ways to separate mixtures and their work was taken further by Mikhail Tsvet, a Russian-Italian scientist who is often credited with inventing chromatography in 1900. The technique has become so widely used, it is now an integral part of testing the quality of air and water, the levels of drugs in athletes, in forensics and in the preparation of pharmaceuticals.

X Minus One was a half-hour science fiction radio drama series broadcast from April 24, 1955 to January 9, 1958 in various timeslots on NBC. Initially a revival of NBC’s Dimension X (1950—51), the first 15 episodes of X Minus One were new versions of Dimension X episodes, but the remainder were adaptations by NBC staff writers, including Ernest Kinoy and George Lefferts, of newly published science fiction stories by leading writers in the field, including Isaac Asimov, Ray Bradbury, Philip K. Dick, Robert A. Heinlein, Frederik Pohl and Theodore Sturgeonalong with some original scripts by Kinoy and Lefferts.

Ron Douglas is Professor of Visual Science at City University and an expert on the biology of deep-sea creatures. He talks to the Wellcome Trust’s Daniel Glaser about how vision works 4000 metres down.
The process of drilling for oil produces the deepest holes in the Earth ever created. Oil must be pulled up from miles below the ground, where it’s been forming through the long processes of time.
The rock brought up to the surface while drilling for oil can be millions of years old. The millions of years have formed a protect layer on top of whatever’s down there, covering with layer after layer after layer of dirt and rock. What is it down there, deep in the past, at the bottom of the hole? Is it just rock and oil, or is there something else being brought up out of the core of the Earth?
