Andrew Marr looks at the ideas and issues that have dominated the world of science in the past year, and those that will be vitally important in the year ahead. Sir Roy Anderson looks at the developments and mutations of swine flu and how the world deals with global pandemics. As a former government advisor, he also explores that thorny issue of when politics and science collide. Richard Dawkins reflects on a year dominated by Darwin, Professor John Shepherd on the blue-sky thinking to combat climate change with a report on geoengineering, and Barbara Sahakian considers whether taking pills to make us clever, well-behaved and sociable will become the norm in the years ahead.
