Mar 13 2008 Scientists Build Coilgun That Stops "Bullets"

Scientists at the University of Texas-Austin have developed a coilgun that can allegedly stop projectiles in mid-air. The coilgun works in the opposite manner of a typical coilgun -- this one slowing down projectiles as opposed to speeding them up. Unfortunately (and I know you will all hate me for this) the "bullets" used in the tests are atom and molecule sized. Not .38s or 9mms or anything like that. But still, it's a step.

The coilgun consists of 64 hand-made units (about $25 each) and is powered by its own capacitor. Here's how it works: The researchers trap particles from the air, store them in a tiny chamber, and release them in the direction of the gun. When a particle reaches the gun and encounters the coils, each coil's magnetic field progressively slows the particle down without touching it. The coilgun brought atoms and molecules traveling at 500 meters per second (1,118 mph) to a complete stop.

Yeah, a lot less exciting than I made it out to be. I apologize. I mean, they already have things that can stop bullets. It's called me. Well, to be fair I haven't actually stopped any bullets. I'd like to think my vital organs slowed them down a bit though. Anyway, the eventual goal of this coilgun project is to weigh neutrinos, which, if I had to guess, are particles that don't want to get involved in the fight between positrinos and negatrinos. But what do I know? I'm no scientist. I'm just a guy who sneaks into the physics lab to heat my coffee with a laser.

Mar 11 2008 Uh-Oh: Nanobots To Take Over The World

Dr. Anirban Bandyopadhyah, of the National Institute of Materials Science in Tsukuba, Japan, has developed a chemical "brain" capable of controlling nanobots. This "brain", soon to be known by the few remaining humans not killed in the machine uprising as "Mother Brain" will control the bots responsible for the demise of humanity. The cave dwelling survivors of the apocalypse will regularly pray to Samus Aran that she return in all her hotness and destroy said brain to make the planet safe for humans once more.

Anyway, the two nanometer "brain" is made of 17 molecules of duroquinone, each considered a "logic device" and controlled by a center "control" molecule. By switching the control molecule in the center with a scanning tunneling microscope, the other 16 are switched based on the logical instructions received. There are over four billion combinations of outcome. At least three billion being "We're all going to die", and the other billion being "We're all going to die slowly."
