As someone deeply interested in ALS research because two people in my family died from this disease, I would urge caution about this type of article. It seems every month someone is claiming to have made a breakthrough in ALS, yet there is no known cure.

ALS is likely an umbrella term for various diseases, as it could stem from multiple causes. In ~10% of the cases, it's of familial origin, but environmental factors, such as eating false morels [1], certain jobs, or playing certain sports, can also trigger ALS, perhaps in a multiple-step manner.

The authors of the Nature article [0] studied whole-blood donations from 40 individuals with ALS and 28 age- and sex-matched healthy controls. This is a very small number to draw conclusions about a disease with such a large disparity of phenotypes that it defeats designing clinical trials.
