Hibakusha Voices at One Young World

We look back on our happiest stories from the past year, including: the man who created 'Christina's Corner' for his most loyal customer; the life-saving medical breakthrough in the fight against Huntington's; and the four-legged litter picker taking the internet by storm. Plus: the survivors of an atomic bomb tell us why they want peace; the blood test helping detect ovarian cancer early; the cafe in Tokyo where people with dementia can volunteer; diplomacy through folk music 'From China to Appalachia'; and the rat that helps sniff out tuberculosis.

Our weekly collection of inspiring, uplifting and happy news from around the world.
