How Pubic Hair Can Actually HELP Deter Sexual Assualt
A sex offender could actually be traced to a crime scene by the bacteria found in their pubic hair.
Anyone who's ever watched a crime show on TV knows that during a forensic investigation, DNA from hair is of the most commonly used forms of trace evidence collected from a crime scene. It always seems to be hair that leads the main characters to the perp, right?
However, for the most part, hairs recovered during forensic investigations usually don't contain enough amounts of human genetic material to be able to perform DNA suspect profiling.
A recent study conducted at the Murdoch University and published in Investigative Genetics has revealed that bacteria found in pubic hair can actually distinguish between guys, girls and individuals.
Researchers discovered that a person's unique pubic hair microbiota get transferred during sex; meaning bacteria detected in pubic hair could be potentially utilized for forensic analysis in cases of sex offending.
The great news that came out of this study is that bacteria found in pubic hair can not only distinguish between men and women and individual persons, but pubic hair microbiota gets transferred over to the other person during sexual intercourse, meaning sexual perpetrators can be traced to their crimes by the hair from their nether regions.
According to lead author of the study Silvana Tridico, in rape cases for example, the transfer of bacteria between the sex offender and their victim could potentially pace the way for an entirely new way of connecting offenders to victims in cases where no human DNA has been exchanged.
The research study conducted at Murdoch University whereby pubic and scalp hair was collected from seven individuals, including a cohabiting couple found that while scalp hair revealed less distinct microbe variations, each study participants' pubic hair contained distinct communities of microbes.
This poses as potential for future forensic implementation in sex crimes.
My only question is, with everyone shaving everything off these days, wouldn't sex offenders simply avoid this potential new form of forensic analysis by adhering to the social pressure to be bald eagle down there?!
