Detects traces of life after the body dies

Researchers found many genes that can last up to four days after the body dies.

According to a study published in the journal Science on June 22, some genes, including the fetal gene and the gene associated with cancer , may be more active after the body dies.

Research may contribute to reducing the risk of cancer after transplantation, and help forensic experts determine when the victim was killed. Professor Peter Noble at the University of Washington in Seattle, USA, said research is an experiment that satisfies the curiosity of what happens when people die . " We can get a lot of information about life by studying death," said Professor Noble.

Researchers learn what happens to more than 1,000 genes in rats and zebrafish after they die. Genetic changes were recorded in four days after zebrafish died and two days after the death of the rat.

" We found hundreds of genes that increased activity for hours after death and some that survived for days. This finding was very unexpected. Because the gene after death was found in zebrafish. and mice, which can infer a similar phenomenon that occurs in other multicellular life forms, " said Professor Noble.

According to the researchers, the finding helps them find a better way to preserve the implant, while also providing many applications in forensic science and murder investigation. Changes in the gene can be used to accurately predict the time of death in the corpse.
