Past research has already demonstrated that the biochemical composition of blood differs between males and females and individuals of different races. But the ability to obtain this information on-site at the crime scene in a matter of minutes could change the way body fluids are processed. In a recent study, Prof. Igor Lednev and his team applied a technique known as attenuated total reflection Fourier transform-infrared (ATR FTIR) spectroscopy to blood analysis, with the aim of establishing whether characteristics such as sex and race can be determined from bloodstains.
“Through the use of biomolecular analyses, such as ancient DNA, stable isotope dietary reconstruction, and radiocarbon dating, we discovered that the history of Roopkund Lake is more complex than we ever anticipated,” said geneticist David Reich of Harvard Medical School.
