If you asked me to guess when the brain goes through the most changes, I would say early life and old age. It turns out, though, that the brain also goes through rapid and unstable changes in middle age. Yet we know so little about the “middle-ageing” brain.
Two neuroscientists at University College Cork explain why knowing more about brain changes at this stage of life could be critical for understanding future dementia risk.
The SS Hartdale was missing for 109 years after being sunk by a German U-boat during the first world war. But a team of researchers has finally tracked down the ship’s final resting place. We hear their fascinating story.
Plus, new research highlights that the multi-million dollar coral reef restoration business may be pursuing a futile enterprise – but innovation could give corals a fighting change.
