Every time your fingers touch your cell phone, they leave behind trace amounts of chemicals. And each chemical offers clues to you and your activities. By analyzing them, forensic scientists might be able to piece together a story about your recent life, a new study finds. One day, police might use such data to help track down a phone’s owner. Or they might figure out what a person had recently been up to.
A molecule is a group of atoms. It represents the smallest amount of some chemical. Your skin is covered in molecules picked up by everything you have touched. Those molecules might include traces of the chocolate bar you had snacked on. Or there might be small amounts of shampoo, cosmetics — even some medicine you took. And with each new thing your skin contacts, you leave behind some small share of what it had touched earlier.
Researchers at the University of California, San Diego (UCSD) recently analyzed such chemical leftovers on the phones of 39 volunteers. These residues helped the scientists analyze each phone user’s behavior.
