Genetic variations and DNA study

Where is my train coming from?

Once I wanted to participate on the action of National Geographic "Genographic" -this was the name, I think. Yes, I'm right and posted the address too. The sense of this project was (and is) to study DNA of most persons possible to understand where are we from.

The studies say, we all come from the same ancestors that lived in Africa about 50-200, 000 years ago, says the site. Than they began to migrate and with time different mutations happened in our DNA. So, if you study the mutations in your DNA using this project, you can know, what way did all your branch till arrived there, where you are today. It's interesting, you are right. You can participate on this project too. The price of the analyze begins from $119. Visit the site and find the today price if you are interested in.

Now with DNA study the scientists can resolve different problems. I give you some examples and hope you'll find something new for you too.

Etruscans
Nobody knew where were those exceptional people from.
Ancient historians had different points of view on this question. Dionysus thought, they are aboriginal from Italy, Titus Livius said, they came from North, Herodotus wrote they are from Livia, a state existed in the territory of modern Turkey till VI b.C.

DNA study of the population of Tuscany demonstrated, from all these opinions Herodotus had right. Etruscans come from Turkey. There were different groups of studies. One of them studied ... DNA of the cows. And even this study showed the same: the cows, original from this zone (Tuscany) have DNA different from all the other cows, living in Italy. Their DNA is similar to those of the cows, living in Turkey. And because the cows could come here only with persons that take them together in their travel, it shows once more, that Etruscans are originally from Turkey. (Lenta.ru)

Do you have blue or brown eyes?
If your eyes are brown, you are "original" as those that came out of Africa many thousands years ago. Because brown is original colour of human eyes.
During their migrations persons had different mutations in their DNA and one of them was the mutation of colour of the iris about 6-10,000 years ago.

“From this we can conclude that all blue-eyed individuals are linked to the same ancestor,” says Professor Eiberg. “They have all inherited the same switch at exactly the same spot in their DNA.”

Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production. (scientificblogging.com)

Poor me... My eyes have a colour that is unpossible to describe...

Breast cancer and deodorant

Some days ago I wrote a review about breast cancer and when I read information in the web about it (to write the post I read many sources), found bad numbers about deaths from this illness.

I know it from experience in my own family, how is important to make controls and that the life is not too long when the surgery was made too late. Well, the notice from Daily Mail is surely not about the case in my family.

One researcher, Chris Exley (hope I write his name good) controlled tissues of 17 women after surgery and found they have great quantity of Aluminium near underarm. Normally this metal don't accumulate in the body. From other side, everybody knows that it's cancerogenous.

The researcher says: they can't be sure that this aluminium came in the ill tissues from deodorants, but everybody knows, it is used to produce deodorants because it blocks the perspiration.

Maybe it would be wise to read what components have our new deodorants befor we buy them?

How to make everybody know about you

This morning I was amused by the way one Japanese company choose to make everybody know about it. This is the notice:

One unknown Japanese company "..." (I don't want to write the name) announced they bought 51% of actions of 6 most big companies like Toyota Motor Corp., Sony Corp., Astellas Pharma Inc., Mitsubishi Heavy Industries and similar paying for it 190 mlrd. doll. (Reuters)

All interested persons began to investigate who is it and how was possible something like this ecc.
Company that no one knew till that day become well known one by ALL the financial world and in all the world too.

Some time later the representatives of listed corporations denied the transactions and demonstrated why is it lie, but the thing was done (I think so).

I say, what means great publicity by free.

Finally online! and the game of tagging

For some days I was without my PC and had not access to internet and to your blogs too.
I ask PARDON to all of you that don't see me visit your blogs.

Unfortunatelly my troubles are not finish else, but till monday I have to be here. From monday I have to take my PC to the technitian once more, with hope to resolve my problems forever.

So, I ask you about a little patience with me, pls.

;))) but till monday I'll be very brave.

Now the Tagging game.

I'm very greatful to Leena she adds my link to her posts very often.

Leena has not only a very interesting intellectual game's blog, she likes to partecipate on tagging games too. In this way I have the benefit to be linked from time to time in her posts. Today she has a new game in this post Viral linking with a difference, she linked me too and now I add here her list.
If you like this game, copy this list and write me about it. I'll add your link here too.

To copy:

I tag Liudmila, André, RennyBA, Jenny and Gil
