Long-Term Space Exposure Alters DNA

This is pretty interesting.

The Twins Study brought ten research teams from around the country together to accomplish one goal: discover what happens to the human body after spending one year in space. NASA has a grasp on what happens to the body after the standard-duration six-month missions aboard the International Space Station, but Scott Kelly’s one-year mission is a stepping stone to a three-year mission to Mars.
Scott’s telomeres (endcaps of chromosomes that shorten as one ages) actually became significantly longer in space. While this finding was presented in 2017, the team verified this unexpected change with multiple assays and genomics testing. Additionally, a new finding is that the majority of those telomeres shortened within two days of Scott’s return to Earth.
Another interesting finding concerned what some call the “space gene”, which was alluded to in 2017. Researchers now know that 93% of Scott’s genes returned to normal after landing. However, the remaining 7% point to possible longer term changes in genes related to his immune system, DNA repair, bone formation networks, hypoxia, and hypercapnia.

The fountain of youth has been in space this whole time

Definition of spaced out

That was only one year in space, no telling what decades of exposure would do.

Maybe his DNA is different because the aliens took him and sent back someone different

Astronauts were from Germany

I've heard of a few people that have had that happen to them...

Thats what she said

Shorter telomeres can lead to more risk of disease. Someone needs to do a study on astronauts and disease. If they have longer telomeres they should have a reduced risk

Interstellar was a market tester of research results to see if the public would accept that Matt Damon would out live us all.

So what does this say?
Will he live to be 150? Does his wang double in size? Is he bulletproof?

This is some cool shite.

Would be incredible to look back on generational changes if they actually develop an outpost on Mars.

Hey, you folks who bitch about NASA being a waste.
This kind of shite is why it’s good.
You keep pushing boundaries and breaking new ground, you never know what you’ll discover.
Now they can start an investigation into why.
Is it the micro gravity? Is it the low grade impact of radiation? If so, what type is ideal? Can the effect be recreated on earth?

Space isn't real

So does this mean that Scott is now a banana?

I think the lack of gravity must have some effect on DNA, down to the molecular level. A good analogy for the DNA lengthening would be how a person gets a bit taller in space because of less pressure being put on spine, allowing it to lengthen back out. I would be interested to see how much effect is from gravity and how much is from more radiation exposure in space(will be really bad going to mars or elsewhere)

This is especially interesting as one of the theories gaining traction is that telomeres are a primary driver in the aging process (each time a cell copies itself, the telomeres shorten).

Well no shite.
It might have something to do with all of that radiation exposure.

I rarely hear people bitching about NASA being a waste. Most bitch about big government spending on welfare and world police instead of this. Also, NASA doesn't help themselves by getting involved in muslim outreach.
