A lot is happening in the world around us. And in space above us. And inside the mice that scientists used to grow human blood vessels. Neat-o! Dork. What's the latest this week in the world of science? Check it out in this week's Science Weekend Warrior!

"No one dies tonight... so says the Phoenix!" And most definitely, Polaris (the North Star, not the Marvel character) isn't one to die off just yet. See, observations of Polaris over the last century have led scientists to believe that the star was about to switch itself off. Poof. Snap. Boom. Asplode. What have you. I'm not really certain what sound a star makes when it switches itself off (especially since sound doesn't travel well in a space vacuum), and I don't think we'll find out soon from Polaris. Despite the continuous drop in vibrations from the star's surface, it's managed to jump-start its way back to life! Now that's hot.
