A scientist has created a revolutionary technique to extract DNA from hair that has long fallen from someone’s head, and is using it to solve cold cases.
Ed Green, a paleogeneticist at the University of California, Santa Cruz, is an expert in finding DNA where others can not and his skills are now being used by law enforcement.
Nuclear DNA is a person’s unique genetic material which can identify them beyond doubt, and can be taken from any part of the body.
However, extracting it from hair has always been a challenge unless it still has the root attached.
Now, Dr. Green, who helped sequence the entire genome of the first Neanderthals and Denisovans, has found a way to do what most experts thought impossible.
