LOL!
I would think that if 7% of his DNA really “mutated,” he would be suffering from all types of cancers.
Nice that there’s an article rebuffing those silly claims, from the National Geographic, no less.

Exactly. Some really big newspapers obviously didn’t read the required reading material and didn’t understand basic biology.

Trueish. It becomes a bit of a whispering game. That’s why checking your sources is so important. Mind you, this is not fake news, but usually just misunderstandings. They can have serious implications anyway, and used to further totally unrelated ideas, such as conspiracy theories. Aka., “the State is sending people to outer space to manipulate their DNA and produce a super race,” or something like that.

That was a very interesting article, and a good explanation of what happens to our DNA throughout our lives.  I know the article only touches on telomeres to explain the process, but I found this part interesting:

 

Normally, telomeres shrink with age, the idea being that each time a chromosome is copied during cell division, the process chips away at that cap. Shortened or frayed telomeres are largely thought to be responsible for age-related cellular breakdown.

But Kelly’s telomeres elongated in space … and then quickly shrank to their original lengths after he returned to Earth. That these structures exhibit such flexibility is intriguing and potentially quite consequential, says Bailey, whose lab studied Kelly’s telomeres.

 

Just shows the complexity and marvel of our bodies, how Jehovah has created us.  Whatever the consequences of the flexibility of our telomeres have on extending our lives, we will one day have the privilege of finding out when Jehovah explain it all to us.  Unlike potential pseudo news, like Thesauron mentioned, sending us all into outer space to live longer.
