The Hello, Hello Dominic. Hello and this week how nuclear bombs have helped to prove that adults make new brain cells.

Is Michael Douglas right when he says his oral cancer was caused by a virus and GPS spoofing can your satinab be tricked into telling you you're

Let's kick off with a look at this week's science news headlines as ever and first up there's evidence now that the

question of whether human adults can make new brain cells and use those brain cells appears

to have been resolved and that has been done using

would you believe it nuclear bomb tests from the Cold War era. This is the work of

Kirstie Spalding she's a researcher at the Karolinska Institute in Sweden.

It's published this week in the journal Cell.

And what she and her team have been developing over the last about 10 years is a way of carbon

dating cells using Carbon which is in the DNA in those cells. So what she has done

is to get samples of brain tissue from people aged between 19 and 92, you extract the DNA from those cells and because when people are

eating food and that food has been grown from plants which is taking carbon

dioxide out of the atmosphere, the amount of

radioactive carbon in the form of carbon dioxide in the atmosphere ultimately ends up in that

person. Now if nerve cells are only born in a person when they are themselves

born in other words one person's set of brain cells has to last a lifetime then
