The Happy Pod: The injection that saved my sight

We hear from a woman whose determination to avoid going blind has inspired her doctors to develop a new treatment for a rare eye condition. Nicki Guy says the injection of a low cost, water-based gel has been life changing and given her the chance to see her son grow up. The treatment has already helped restore the eyesight of dozens of other people with hypotony - which can cause the eye to collapse, leading to blindness. Also: the new Barbie doll that's designed to help improve understanding and acceptance of autism. A neurodiverse writer says she hopes it will help young girls understand it's not something to hide or be ashamed of. A revolutionary way of treating some cancers is being offered to people in the UK with an aggressive form of leukaemia for the first time.

Plus, how one man's regular habit of having gumbo at the same restaurant twice a day may have saved his life; the 24-year-old in charge of protecting the Pacific Ocean around the remote Pitcairn island; and the amateur football team who pulled off one of the biggest upsets in English footballing history by beating a side from the Premier League.
