The truth is that this news is very brave and it caused me grace to think that a mouse doesn't fear a cat to modify his genetics. I doubted to put it in this section why thinking it a little the truth thought the quantity of things that they can only be achieved modifying part of the code of the DNA of an alive being.
They imagine the nerds taking a pill to make him front
to the small hoodlums that marry them of spot jaja!
Japanese investigators were able to modify the genetic structure of a rodent, giving life to an animal that can play gently with their " enemy ".
The game of the cat and the mouse will no longer be the same one. Scientists created a rodent mutant that lost their instinct of fear to the felines, the periodic The he/she informed Independet.
By means of a genetic change in the sense of the smell of the mouse, the investigators caused him the loss of the ability to associate the scent of a cat with the fear to a potential predator.
The result was a rodent that can play friendly with a feline without showing the most minimum alarm sign.
The study for Hitoshi Sakano, of the University of Tokyo,
who he/she affirmed that the investigation is important because it shows that it is possible to counteract the natural ill will that the mammals –incluyo the humans - they have in front of certain aromas.
Introducing a gene of the toxin diphtheria in the mouse, the scientists could remove certain nervous cells of the smell bulb of the animal that it is located in the base of the brain selectively and he/she receives nervous impulses of the smell receivers that are in the nasal cavity.
The professor's study Sakano explains that the smell bulb is formed by two types of nervous cells: those that respond to innate impulses and those that react before learned situations. According to the own specialist, their work it was able to discover that these two types of cells are separate the some of the other ones.
"These results indicate that, in the mouse, the information of rejection is received in the smell bulb by groups separated from nervous cells: those dedicated to the innate thing and those that respond to that learned". AND, thanks to the manipulation, the mouse mutant lacked innate answers to the scents that generate him rejection, although it was able to detect them", he added.
The next step of the investigation will be to look for more even of circuits in other parts of the sensorial system of the mammals.
With regard to the images that illustrated the study, Sakano clarified: "The cats were very fed before taking the pictures. Otherwise, they would have killed our valuable mouse mutant."
