Blood
DNA
Excursion Time
On Tuesday, Sep 8 2015, our Forensics Science class went to visit Victoria Police Museum to learn more about Forensics Science with different materials used and famous crime cases in Australia. We also had a chance to investigate a built up case by the Museum base on the corpse of the victim. During the excursion, there was a Forensics Technique that I found very interested in which was Forensic Odontology. Our teeth is extremely hard. Class can be melt under fire but not the teeth. In the crime scene or cases where the victims are all terribly burn, the only part that help the investigator to rely on is the teeth. After the Black Saturday, the police went to Mrs John's house and discovered a remaining body, they couldn't conclude that body was Mrs John's. But base on what was left behind was the teeth, so they used a kind of gel and create a mold of teeth with the exact shape of hers and gave it to the dentist. The result matched with the body. Forensics Odontology is really important.
DNA of Dinosaurs
DNA of dinosaurs is completely different from human DNA. the researchers have discovered 75-million-year-old red blood cells and proteins. This discovery indicates that blood and other cells might be preserved much longer in fossils than previously believed. And studying these cells in the future could give us brand-new insights into how dinosaurs looked and behaved. However, the chance of getting DNA from the cells is very low but not never. Perhaps, one day DNA fragments might be found in an exceptionally preserved dinosaur fossil. At the moment, there is no accurate evidence or certain conclusion about Dinosaurs, but the scientists all over the world have been trying to figure out how Dinosaurs DNA is and how it looks like.
