Fingerprints have been used for centuries to identify people and are one of the most common crime-fighting tools. But with advancements in DNA, GPS, and iris scanners, are fingerprints losing status? Forensic scientists say fingerprints are still one of the most reliable tools they have to crack crimes but only if handled properly. On a Science Café edition of the Sound of Ideas, we’ll investigate the whorls, loops and arches on our fingers. We'll uncover why we have fingerprints, how they’re lifted from crime scenes and hear about the switch from ink and roll to digital technology. Join Regina Brett and guests, Friday morning at 9 on 90.3.

Regarding the issue of children fingerprinting: If fingerprinting is difficult but DNA swabs are an alternative maybe there should be an option to have your child’s DNA collected at birth. Has this ever been proposed?
If someone has an accident and cuts his finger, does the finger print changes or with time the skin will regenerate itself to get back to the same finger print?
