Re: How do satellites not crash into each other?

Pardon the ignorant question, but for all of the debris in or near LEO, why does it not all eventually fall out of orbit since it has no thrust capabilities? Or is it just a slower process than I'm imagining?

Re: Human Gut Microbiome: Essential or Not?

What happens if you recolonize adult germ-free mice with normal gut flora? Do they gain significant protection from pathogens? Is their immune dysfunction ameliorated at all? Yes*, see here for an example: http://www.ncbi.nlm.nih.gov/pubmed/24629343 *Note this is only one model system of infection.

Just to play Devil's Advocate, if you have two forces pushing on the box, one bigger than the other, then the greater magnitude force is going to accelerate the box away from whatever's providing the lesser force - eg you can't stand behind a car and push it forward if the engine has already pushed...
