This amazing event, dubbed "The world's greatest science festival" has something for everyone, from naked mole rats to record-breaking cars. There will be fascinating talks by a wide range of scientists and presenters alongside a host of exhibitors offering brilliant interactive activities. We'll be there and we hope to see some of you there too.

Check out the latest BTO migration blog.
