Lack of Sleep = Cold?

Studies show that poor sleep and susceptibility to colds go hand in hand. In a recent study, scientists followed 153 men and woman for two weeks, keeping track of their duration and quality of sleep. Then, during a five-day period, they exposed the subjects to cold viruses. It turned out that those who slept an average of fewer than seven hours a night were three times as likely to get sick than those who averaged at least eight hours.
It seems that sleep and immunity are tightly linked. Studies have shown that mammals that produce greater levels of white cells also require the most sleep. And researchers have shown that species that sleep more have more resistance against pathogens.

Monkey on Mars

Russia is going to send a cosmonaut (that's what they call astronauts. Yay, new vocabulary!) to Mars. But there's a problem. No one knows how the radiation exposure during a year-and-a-half-long flight would harm travelers. A monkey has volunteered to travel instead. At least, I hope so. It'd be cruel to force the monkey to do it.
The monkey will be taken care of by a robot. Is there going to be any kind of human or even sub-human on this journey? How come robots and monkeys are going to Mars before human?
Back to (monkey) business! The robot will feed the monkey and clean up after it. The humans will have to teach the monkey how to cooperate and work with the robot. Back to kindergarten!
I still think the monkey should get paid.
