It's fun to toss around theories about how there might be other universes out there, and there may even be some evidence that at least four of them have smashed headlong into our universe. You'd think proving that this is the case would be tricky, but neutrons may be taking trips to other universes all the time.
Classical physics is good at describing the motion of big things (such as planets), while quantum physics is needed to describe the behavior of small things, such as atoms. But if you get a big enough atom, its electrons should orbit around just like a planet orbiting the sun, and physicists have managed to make that happen.
You'd have to be a pretty small ninja to wield one of these stars, since they're made of molecules. Or rather, each star is just one single molecule all tied in knots, and they're the most complex molecules (outside of DNA) that we've ever synthesized.
Though searching for a fountain of youth might sound like something out of a King Arthur story, it's also something happening right now, across the world, as scientists race toward discovering immortality. It might make marriage proposals seem a bit heavier, but some folks out there are dedicated to figuring out how to live forever (which sounds expensive).
The largest man-made structure on Earth is the Great Wall of China. The second largest is about to be the KM3Net neutrino detector, which will span several cubic kilometers under the Mediterranean, listening for whales. Oh, and looking for neutrinos. That too.
How high-speed can a high-speed camera get? Try fast enough to watch a pulse of light itself move through a soda bottle.
At CERN today, home of the Large Hadron Collider, particle physicists announced the most recent (and most tantalizing) results in their search for the Higgs Boson. They haven't nailed down the elusive particle quite yet, but they're closer than ever before, and they may now know just exactly where it's hiding.
From yarn to batteries to space elevators, it seems like there's nothing that carbon nanotubes can't do. And for their latest trick, they can make things completely disappear.
Remember the last time you walked into a room and forgot what you were there for? Absurd lack of parallelism aside, it's something we all experience, and apparently it isn't just some random occurrence. A team of researchers in the state of Indiana say there's a bona fide, scientific reason for it.
Once again, I don't know where this kind of thing was when I was in school, but students at University of Canterbury in New Zealand have built themselves a sort of horizontal, man-made lightning cannon. Oh, did I say cannon? I meant, uh, "research project." Yeah.
