This is where we're at

From the AP: Cloak of invisibility takes a step forward.
Researchers at Germany's Karlsruhe Institute of Technology report they were able to cloak a tiny bump in a layer of gold, preventing its detection at nearly visible infrared frequencies.

Their cloaking device also worked in three dimensions, while previously developed cloaks worked in two dimensions, lead researcher Tolga Ergin said.

The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump in the gold later beneath, the researchers reported in Thursday's online edition of the journal Science.

From Nature: Scientists supersize quantum mechanics.

A team of scientists has succeeded in putting an object large enough to be visible to the naked eye into a mixed quantum state of moving and not moving.

Andrew Cleland at the University of California, Santa Barbara, and his team cooled a tiny metal paddle until it reached its quantum mechanical 'ground state' — the lowest-energy state permitted by quantum mechanics. They then used the weird rules of quantum mechanics to simultaneously set the paddle moving while leaving it standing still. The experiment shows that the principles of quantum mechanics can apply to everyday objects as well as as atomic-scale particles.

Okay, people of Earth. You are officially no longer allowed to complain that it's the year 2010 and there are no jetpacks or flying cars. You're looking for cool future tech in the wrong place.

So cool!

I find the quantum physics part really cool--both moving and not moving. Hopefully that's the first step to space travel :P
