Wimbledon Grass Science

We visit Wimbledon’s iconic Centre Court... but we’re not interested in the tennis, we want to know all about the grass. Just how important is science to cultivating the perfect playing surface? Also this week, we discuss the aims and ethics of human stem-cell-based embryo models in research after a new code of practice for the UK made headlines. And we answer a listener question about whether white paint could help tackle climate change. Send your burning science questions to insidescience@bbc.co.uk.
