The theme of our 20th science4u conference is Science for Celebration. It feels apt that the 20 year anniversary for this wonderful event has a celebratory feel because this year has seen a number of clinical landmarks worthy of celebration too. We have seen the return to normality (or nearly!) following the global pandemic and the success of the incredible vaccination program that has permitted this. This year has also seen the rollout in the UK of the first population-wide newborn screening program using DNA, which has already saved babies' lives. We also saw the first gene therapy given for T-cell acute lymphoblastic leukaemia, the expansion of artificial intelligence into clinical diagnostics, and an agreement to try two new drugs to combat antibiotic resistant microbes.

We invite you to use your imagination about how scientists might make further vital breakthroughsin healthcare over the next few years.
