Chemist and biologist Lesley Chesson, president of Salt Lake City-based IsoForensics, Inc., is Science Unwrapped's featured speaker Friday, March 21.

 

CSI Chemistry: "I Know Where You've Been and What You Ate"

Different forms of elements, called isotopes, are found everywhere in the environment. These isotopes are incorporated into materials in varying ratios and the abundance of different isotopes, thus, serves as a record of the material's formation. Analysis of a material for its distinct isotope signature can, therefore, be used to reveal its history.

Science Unwrapped welcomes chemist and biologist Lesley Chesson, president of Salt Lake City-based IsoForensics,Inc., who'll tell us about the field of stable isotope forensics.

"Investigators apply stable isotope analysis to a variety of materials of forensics interest, including drugs,explosives, money, food, ivory and human remains," Chesson says. "For example, the isotopes in human hair protein can reveal the age of an individual, what he or she ate and how often and where they traveled."

Following Chesson's talk, Science Unwrapped attendees are invited to enjoy free refreshments and a variety of hands-on learning activities.

Join us at 7 p.m. in the Emert Auditorium (Room 130) of the Eccles Science Learning Center.
