New Study Shows Hand Scent Alone Can Accurately Reveal a Person's Sex

Researchers analyzed scent compounds on 60 people's hands and correctly identified their sex 96.67% of the time.
The analysis used mass spectrometry to examine scent compounds on participants' palms.
The discovery could help law enforcement identify suspects in certain crimes where hand scents are left behind.
Some critics argue scent identification can lead to wrongful arrests and violates civil liberties.
Previous research shows scent also reveals a person's age, race, and ethnicity.
