Water Bears!

That's right, I figured my first official blog post had to be something both scientific and adorable. (Must credit my sister for finding the video...see link in text below, because I'm too slow to figure out how this whole blog posting thing works.)
"Tardigrades — barely visible invertebrates that cling to mosses and lichens — are...virtually indestructible.In recent years, scientists have subjected tardigrades (which are also known as water bears) to extreme temperatures, ranging from 155ºC to –200ºC. They've deprived the creatures of food and water for years at a time and zapped them with incredibly toxic levels of radiation. But, just like a Timex watch, water bears keep on ticking. Earlier this month, scientists reported that a colony of tardigrades had even managed to withstand the vacuum of outer space. (The European Space Agency put the creatures on a satellite and sent them into orbit for ten days.) If our life form manages to destroy the earth as we know it, maybe we can take some solace in knowing which other species will survive us."
