Trip To Mars Could Damage Astronauts' Brains
Hugh Pickens writes writes "Alex Knapp reports that research by a team at the Rochester Medical Center suggests that exposure to the radiation of outer space could accelerate the onset of Alzheimer's disease in astronauts. 'Galactic cosmic radiation poses a significant threat to future astronauts... Exposure to ... equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer's disease' says M. Kerry O'Banio. Researchers exposed mice with known timeframes for developing Alzheimer's to the type of low-level radiation that astronauts would be exposed to over time on a long space journey. The mice were then put through tests that measured their memory and cognitive ability and the mice exposed to radiation showed significant cognitive impairment. It's not going to be an easy problem to solve, either. The radiation the researchers used in their testing is composed of highly charged iron particles, which are relatively common in space. 'Because iron particles pack a bigger wallop it is extremely difficult from an engineering perspective to effectively shield against them,' says O'Banion. 'One would have to essentially wrap a spacecraft in a six-foot block of lead or concrete.'"
A Democrat is just a Liberal who spends other people's money to not feel guilty when he helps homeless people.

A Democrat is just a Liberal who spends other people's money for programs that give the appearance of helping poor people, while in fact creating a larger base of poor people to justify the existence of the programs.

Booom, instant "(Score:0, Flamebait)"! Good to see free speech is alive and well!
So, making jokes about Democrats is funny, but making jokes about Republicans is flamebait? Good to see free speech is alive and well!
Hah, it gets funnier and funnier! Now my sig has been blanked. So, the site mods are totally impartial, are they?
