Space travel can accelerate Alzheimer’s: U.S. study

Source: Agence France-Presse

Long journeys into deep space, including a mission to Mars, could expose astronauts to levels of cosmic radiation harmful to the brain and accelerate Alzheimer’s disease, said US research Monday.

The NASA-funded study involved bombarding mice with varied radiation doses, including levels comparable to what voyagers would experience during a mission to Mars, and seeing how the animals managed to recall objects or locations.

Mice that were exposed to radiation were far more likely to fail those tasks — suggesting neurological impairment earlier than such symptoms typically appear.

“Galactic cosmic radiation poses a significant threat to future astronauts,” said Michael O’Banion, a professor at the University of Rochester Medical Center and senior author of the study published in scientific journal Plos One.

Why would anyone want to jump out of a perfectly good Airplane?

Put on your Tinfoil Hats to protect you from Cosmic Radiation........Good luck with that.

13. if galactic cosmic radiation is the cause, it would make sense to me that without an ozone...

we shouldn't have to leave the planet to experience this.

21. It makes me wonder about air travel

Pilots and frequent fliers might also have elevated risks, even though x-ray dosages would be much less severe.
