Science history: Doctor identifies transmissible proteins A doctor hypothesized that proteins can be transmitted to cause diseases like mad cow.

· #ScienceHistory ·
On April 9, 1982, a doctor at the University of California, San Francisco, published a paper in the journal Science showing that infectious proteins caused a degenerative nerve disease in sheep. In doing so, he transformed our understanding of how some diseases are transmitted.
