Because of Joy, scientists developed a simple, non-invasive, three-minute skin swab test that analyzes sebum to diagnose Parkinson's. In laboratory settings, this test has shown an accuracy rate of over 90%.

Unfortunately that insight hasn't led closer to a cure.

It also turns out sort of bad to tell people they have a horrible neurodegenerative disease 10 years before the major symptoms start.

Why isn't everyone's mind blown? Well for the cynical explanation, look at the state of science education and what people said about Artemis, vaccines, etc. or optimistically, there are too many mind blowing discoveries to treat them all fairly.
