Chemicals stored in home garages linked to ALS risk

Storing chemicals in a garage at home may associate with an increased risk of ALS, a study finds. This comes as research has found that exposure to environmental toxins, such as pesticides and volatile organic compounds, are also linked to ALS development. Researchers call the buildup of exposures of the lifetime the ALS exposome.

The researchers also discovered an unexpected social life—the rats appear to be monogamous and may even form small family units with their offspring.
