Have you ever wondered how we can tell the differences between identical twins that share the exact same look? If one of them commits a crime, how would the police know which one is actually guilty? With recent advanced technology, forensic science is able to tease out several minute differences in our genomes that help to differentiate the twins. However, back in the old days, how were the police and detectives able to do their jobs and maintain justice in our society? It is because in addition to our appearances and DNA sequences, each and everyone of us has another feature that identifies who we are – the fingerprints. Fingerprints are composed by patterns of ridges and valleys found on our fingertips, and they are extremely unique for each individual. No two people have ever been found with the same fingerprints. Even identical twins have different fingerprints. Also, do you know that we actually leave our fingerprints on everything we touch? That is how the detectives are able to follow traces of criminals, figure out who they are and put them in jail. Sound cool, right?
Want to study more on how fingerprints are formed, how they can be so unique, and how we are able to record them accurately and distinguish one from another? You are welcome to join us and the local kids in a science event on September 25th, 2016. This activity is supported by the Vietnamese STEM community.
