A social media craze has done some good.

FOX's Chris Hoenig reports:

Remember the ice bucket challenge? It seemed like everyone was doing it, such as LeBron James...

Well, some of the money raised by it has helped identify one of the key genes involved in ALS, or Lou Gerhig's disease.

In a paper published in the journal Nature Genetics, Project MinE researchers say the discovery of the NEK1 gene will help in understanding and developing new therapies for the disease.

The ice bucket challenge helped raise more than $100-million for ALS research, Project MinE receiving $1-million of that.
