Forensic science gets a significant upgrade. Pioneering research reveals a breakthrough: ancient DNA techniques, onc reserved for woolly mammoths, are now crucial for identifying severely burned human remains. This innovative method, detailed in a Binghamton University study, allows scientists to extract usable DNA from bones exposed to high temperatures, offering a vital secondary_keyword that assists in the identification process, especially when dental records are insufficient. Analyzing bone discoloration to determine fire heat is also a scientific advancement. Long bones are the most effective source for DNA recovery.

Ancient DNA Technique Plays Key Role Identifying Burned Remains
Updated June 15,2025
A method initially created to extract DNA from ancient specimens,including woolly mammoths,is now being used to identify badly burned human remains,according to a Binghamton University study.The technique plays a key role in modern forensic science.
While dental records can sometimes identify fire victims, DNA testing frequently enough becomes the only viable option. Researchers have found that usable DNA can be extracted from bones burned between 200 and 250 degrees Celsius. However, DNA concentration drops sharply between 350 and 550 degrees Celsius.
Matthew emery, research assistant professor of anthropology at Binghamton University and lead author of the study, said there’s an inverse correlation between burn temperature and DNA preservation. “Part of the idea was to look at how DNA degrades systematically across different temperature ranges,” Emery said.
The research team used two different DNA extraction techniques on bones and teeth from 27 fire victims involved in house fires, plane crashes, and vehicle accidents.
One technique, initially designed for extracting ancient DNA from Ice Age animals and archaeological human remains like Neanderthals, was used. The second, the total demineralization protocol, was developed by odile Loreille, an FBI forensic scientist and co-author.
Both methods proved effective up to 350 degrees Celsius. The forensic DNA protocol is preferable below that temperature, while the ancient DNA technique amplifies shorter DNA fragments, making it more useful in hotter fires.
Researchers also developed a method to estimate fire heat by examining bone discoloration. Bones heated below 200 degrees Celsius are typically well-preserved. Yellow and brown discoloration indicates temperatures between 200 and 300 degrees, while a black or smoked appearance suggests 300 to 350 degrees. Bones exposed to 550 to 600 degrees may appear grey, and higher temperatures result in a white or calcined appearance.
This knowledge helps forensic scientists select the most suitable bones for DNA extraction, improving the role of DNA analysis in identifications.
“The whole point of the study is to devise a best practices approach for forensic anthropologists and forensic scientists working in the field,” Emery said.
Bone type also matters. Long bones, such as the tibia, femur, and ulna, are the best reservoirs because their thick, hard exterior preserves DNA, Emery said.
Emery is currently working on another project with Maricopa County burn remains, aiming to identify cold-case victims.
“In these cases, the technology wasn’t there at the time to identify them,” he said. “The same techniques that are used in the field to get DNA from woolly mammoths, we’re now using to get DNA from victims in cold cases.”
What’s next
The research team hopes their findings will refine forensic practices, improving the identification of fire victims and resolving cold cases through advanced DNA analysis.
