Submission + - Termite Networks are Architects of African Savanna (discovery.com)

reillymj writes: Termite mounds form a vast, evenly-spaced network throughout the African savanna. From satellite photos, scientists have found that the mounds are actually the underpinnings of the entire savanna ecosystem — from lions to giraffes down to geckos and plants, everything starts with the these mounds. And their spacing is important — researchers found that when they tried to randomly space the mounds in a controlled experiment, the whole thing fell apart. Somehow termites have engineered a vast complex natural system that's given rise to some of the world's most famous large beasts simply by building piles of nutrient-rich dirt in a specific pattern across the Serengeti.

Because if they've managed to make their way all to way to us, they must be organized and unified to a large degree, and that doesn't happen if there is still someone around who wants to wage war. They'd be busy fighting each other for (relatively, as in planetbound) small rewards, like we are. Also, sending an invasion fleet with all the necessary weapons, armour and equipment across the stars would break the back of any planet's economy. Since even a peaceful interstellar expedition would be incredibly expensive, they'll be looking to to recoup some of the costs.

That and the fact that a large part of the internet lists their birthday as being January 1st, some year that makes them older than eighteen. Personally I find that a single twirl on the scroll wheel of my mouse generally makes me be born somewhere in the late seventies or early eighties these days.

Goodness me, I would have thought that the trade between France and Germany was significantly reduced after France declared war in 1939. Or maybe, you know, after Germany invaded France in 1940. If you had said before 1939 you would have been correct, remember that the USA arrived late for the party that was WWII.

That is a good idea, but on the other hand it might not be so cheery for the average Facebooker to have to answer questions when registering about what to do when they (inevitably) die... The logic is obvious, people's reaction to something that might be called morbid is a lot harder to gauge.

The top end of your scale is about right, 40C is 104F, which I do believe as you, is too damn hot, however, I'd put the -10C into the biting cold category, and -20 is simply too cold to go outside. 0 to -9 is the normal winter day and anything slightly above freezing is mild winter.

That depends entirely on where you live, my friend. Here in Norway, some schoolchildren will happily walk to school in -20C on a daily basis during the winter, where I currently live -10C is pretty cold but yet quite normal and certainly doesn't inhibit daily life. And don't even get me started on these wimpy "snow days" that seem to play such a large part of American children's hopes of getting off school.

The movie Space Cowboys had a similar device, a satellite that would launch a bunch of warheads at the USA when it lost contact with the Motherland (or was approached by other spacecraft). Obviously it started failing, which also would trigger the launch, and the only ones old enough to know how to fix it were Clint Eastwood and his gang! One helluva movie.
