Description

The latest developments in health, medicine, environmental issues, space and technology feature in this exciting and thought-provoking package of science stories. This episode looks at the race to build a radically different kind of computer - a so-called quantum computer - in which the microprocessors are individual atoms; a team of Australian researchers that is conducting a world-first study to discover how high risk children can be spared the agony of full-blown anxiety disorders as they grow into adulthood; tiny creatures called chitons that make teeth of solid iron; a LIDAR laser being built in Tasmania and destined to be sent to Antarctica to take the temperature of the atmosphere 90km above the Earths' surface; and a new technique that is helping surgeons detect the single lymph node most likely to be affected by cancer - the so-called 'sentinal' node.
