reCAPTCHA provides the user 2 words to decode. One of them is known on the server side (like traditional captcha), but the second is an unknown word that failed the optical character recognition process.

With 60 million captchas solved by human eyes every day, this could really assist the digitization of printed works for the Internet Archive.

IBM researchers James Frye, Rajagopal Ananthanarayanan, and Dharmendra S. Modha assembled a simulated mouse cortical hemisphere (that is, a functional half of a mouse brain) on one of the smaller BlueGene/L supercomputers. They then ran the simulation -- at ten seconds of computer processing equal to one second of brain function.

In other words: they ran a simulated mouse brain at 1/10 time.
