There may be a warning signal in our brains that helps us keep out unwanted thoughts. The team hears about the fascinating word-pairing method researchers used to identify this mechanism, and how the findings could help people with PTSD, OCD, and anxiety disorders.
When we talk about climate change, we often think of its dramatic global consequences. But it’s having effects everywhere and to make that point, this week Rowan visits Wytham Woods in Oxfordshire.
