From matches to penicillin to X-rays, science is littered with accidental discoveries. Here's another recent entry.

A University of Ottawa researcher's experiment with multiple sclerosis (MS) patients didn't quite work out as planned, but in an unexpected twist seventeen of them who had received bone marrow transplants experienced a remission of the disease. It should be noted that MS is considered to be incurable. Here's an excerpt from the story:

Patients who got bone marrow stem-cell transplants - similar to those given to leukemia patients -- have enjoyed a mysterious remission of their disease.

And Dr Mark Freedman of the University of Ottawa is not sure why.

"Not a single patient, and it's almost seven years, has ever had a relapse,'' Dr Freedman said.
