Already able to identify faces with DNA, where does the criminal run for escape?
Which "path" for criminals is now able to build a face from a collection of DNA from the scene.
Recently, a genetic technology company called Parabon Nanolabs used DNA collected from the crime scene, through which the image of the culprit's face was created.
And this picture is the result that Parabon company handed over to the police.
In fact, this is not the first time this company has used genetic technology for the purpose of supporting investigation. Earlier in May, Parabon Nanolabs joined an advertising agency in Hong Kong to create large posters with faces of indiscriminate garbage people.
Using DNA collected from gum residues as well as cigarette filters, Parabon focuses on genes that regulate basic human characteristics such as hair color, as well as eye color. Later, they used computers to create images of the faces of environmental polluters, then printed on large-format posters pasted in crowded places across the city.
The faces of littered people are stuck in crowded places.
Build up "nowhere" word faces
Few people know that the idea of building a face based on DNA has existed for a long time.
In 2012, a New York painter - Mrs. Heather Dewey-Hagborg - used this technology to create the faces of unknown women, through DNA obtained from cigarette filters and high candy residues. su on the street.
Mrs. Heather Dewey-Hagborg is also a work of her.
In order to extract DNA, she only needed to perform a very simple procedure at a London lab. Then, Deway-Hagborg uses a special code based on face-building software written by researchers at the University of Basel, Switzerland to extract genes that regulate appearance characteristics like hair, eye color. In addition, DNA also gives information such as skin color, width of the nose, distance between the eyes, etc.
Her exhibition, called "Unusual Faces" , has been opened in many countries around the world.
Only "almost" only
Because DNA cannot give us information about health, as well as age, so faces are made up of only similarities, not perfect copies. According to Mrs. Dewey-Hagborg, these faces are like "family members".
The faces that Parabon has created are no exception."We can only help authorities have an overview of who they need to look for," said Ellen Greytak, the company's director .
Another face created by genetic engineering.
Understandably, because each of us contains more than 3 billion pairs of chromosomes - denoted by letters A, C, G and T. One of the methods of gene analysis is focusing on those Chromosome groups come with specific characteristics , such as hair, eye color, resistance to certain diseases, etc . This analytical method is called SNP by scientists. .
In general, this method is very effective in analyzing some specific human characteristics. For example, scientists can predict blue or brown eye color, as well as red hair with almost absolute accuracy. However, it is much more difficult to determine if a person is blond. At the same time, factors such as face shape, or height are another issue altogether.
