British scientists from Staffordshire University and the University of Hull have studied the behavior of blood droplets in microgravity conditions for the first time. The results of the experiment should form the basis of a new branch of criminology dedicated to solving crimes beyond Earth. The article was published in the scientific journal magazine Forensic Sciences International: Reports (FSIR).
“Examining the shape of bloodstains can provide valuable, constructive information about a crime or accident. But little is known about how liquid blood behaves under changing gravitational conditions. “Although this area of research is new, it has implications for forensic investigations in space,” said forensic scientist Zach Kowalske. “It contains,” he said.
The experiments were conducted on a modified Boeing 727 aircraft. The researchers used a mixture of 40% and 60% red food coloring that simulated the density and viscosity of human blood.
“Due to the lack of gravitational influence, the surface tension and adhesion of blood droplets increases. This means that blood in space has a higher tendency to stick to surfaces. Regarding the formation of blood spots, this means that the droplets spread more slowly in zero gravity and also have shapes and sizes that are not typical for Earth “It means it is,” explained study co-author Professor Graham Williams.
According to the authors of the scientific study, due to the pace of technological development in space exploration, the need for reliable forensic methods will become increasingly important and will lead to the emergence of astroforensics.
