The Ice Bucket Challenge that went viral in 2014 has funded an important scientific gene discovery in the progressive neurodegenerative disease ALS, the ALS Association says.
Scientists have identified a new gene contributing to the disease, NEK1.
The Ice Bucket Challenge has raised $115m (£87.7m) from people pouring cold water over themselves and posting the video on social media.
It was criticised as a stunt, but has funded six research projects.
