If there can be a faint silver lining to this outbreak, it's that researchers have been able to study the evolution of the virus in a way no previous Ebola epidemic has allowed. With thousands of cases documented to date, investigators have been able to track mutations in the virus' RNA genome—and they found hundreds of mutations just in viruses examined before the publication of a paper in Science in August. In a tragic footnote, five of the authors of this paper died of Ebola during this outbreak.
