A few days ago, science journalist Claire O'Connell wrote a brilliant article in the Irish Times on how scanning the brain activity of teenagers, as they listen to music, can help determine whether the track will be a hit amongst the wider population. Then, Science Week co-ordinator Donna McCabe recommended this video - a clip from 'Science of the Movies' - which looks at how movie studios are using science to determine if their movie trailers will attract an audience. Fascinating stuff. You might also find these videos interesting - a brain scan of a man aged 20-25 as he watches the trailer for 1. Avatar and 2. Beyonce's "Single Ladies".
