This story about a new development in analyzing material collected in a rape kit may be bad news for rapists, but it is good news for justice.
The science of collecting evidence from rape victims is being expanded at the University of Virginia. The technology is called “Sperm Paint.” This revolutionary new technology could help police solve rape cases that previously had to be tossed aside due to a lack of evidence.
According to the story, the current process requires finding intact sperm which is harder than I assumed it to be since sperm cells break apart quickly. The new process identifies the tail of the sperm by a protein that can't come from anywhere else.
This new process also may increase the time available for collecting viable evidence which is definitely good news.
