Geneticists at the University of Georgia have accomplished the first ever editing of the genes of a lizard with the gene editing tool CRISPR.  

 

The scientists weren’t shocked that the process worked, but they were surprised at the extent to which it was effective. That’s because the technique they were pursuing was a kind of work around for a peculiarity of reptile reproduction.

Experts call it a major game-changer for cold-case investigations: DNA and genetic genealogy. These methods can also identify living people. For example, DNA profiles pulled from publicly available ancestry websites were used to identify and arrest The Golden State Killer for a series of murders dating back to the 1970s and 80s. Cece Moore is chief genetic genealogist with Parabon Nanolabs and PBS’s Finding Your Roots with Henry Louis Gates, Jr. She talked about the relationship between DNA and law enforcement.
