ABC, a Spanish news paper published a new where it say that a group of Scientifics of the Swiss Federal Institute of Technology Zürich had discovered that the environment leaves a mark in our brain and then a little RNA can pass the information about our experience to the next generation.
It was discovered in the psychology. The scientist Isabelle Mansuy said ”There are diseases such as bipolar disorder, that run in families but can’t be traced back to a particular gene”. She and her team discovered that the enzymes of the RNA contain some molecules called microRNAs, which control how many copies of a particular protein are made and others functions. They are changed with traumatic stress alter and they go to the brain, the blood and the sperm and then they pass to the descendent.
But this information normally appear in the third generation because the traumatics cases stay in the brain, in organs anf also in the gametes.
We can see this article in the ABC (a newspaper) and in the page of the ETHZ (Swiss Federal Institute of Technology Zürich), and we have the full information in the Nature Neuroscience, but it is a private document where you have pay to see it (PDF)
We can see some differences because in this type of documents the writers always change some numbers or information, but in this case the changes are not problematic.
I chose this article because it looks very interesting.
In my opinion, the discovery is good for explain how we can have feelings, in this case bad feelings, feelings that parents and a son can feel when something happened.
It does not resolve something for the sciencie that the scientists can use to treat some desease, even though it is so necessary for families interesting in this cases. Even though i hope that the sciencia will continue inventigate about this because some day we can prevent all bad things that occur in our organims.
