UK: Stephen Fry urges help for bipolar gene study
Stephen Fry is encouraging people with bipolar disorder to take part in a university's research into how genes can contribute to the illness.
The actor, author and presenter has taken part in Cardiff University's study, along with TV personality Kerry Katona.
Researchers need to double the number of the 3,000 volunteers who have so far donated DNA samples for analysis.
Fry said volunteers would help "remove stigma, shame and hidden pain".
